Abstract
Background: This study aimed to determine the prevalence and mean infection intensity of zoonotic foodborne trematodes (FBT) in small indigenous species (SIS) fish hosts. Materials and Methods: A total of 8630 specimens of unknown origin were collected from the markets in Phnom Penh City. Fish were identified, weighed, and separated into 20 g subsamples for each fish species, and were examined using the artificial digestion method. A total of 10 species of FBT were detected in 11 species of fish out of the 23 species of fish in the total sample. Results: All infected FBT species were intestinal flukes. No liver flukes were found. The overall prevalence of FBT infection was 29.3% ± 5.3%, and the mean intensity was 0.85 ± 1.89 metacercariae (Mc)/g. The highest FBT prevalence was observed for Isthmiophora hortensis (10.7%) and Centrocestus formosanus (7.9%). Other species identified were Diplostomum spp., Echinochasmus japonicus, Echinostoma revolutum, Echinostoma sudanense, Haplorchis taichui, Haplorchis pumilio Heterophyes spp., and Procerovum varium. The highest mean intensity was found for Diplostomum spp. (1.75 ± 3.03 Mc/g). Trichopsis vittata was one of the main species constituting the SIS in urban markets (31.72%) and showed the highest prevalence of FBT (75.0%). In addition, T. vittata had the highest diversity of intestinal flukes compared with other fish species. Amblypharyngodon chulabhornae showed the highest mean intensity. but low diversity (only two species) and low prevalence. Conclusions: T. vittata could be considered a potential indicator for targeted monitoring of FBT intestinal flukes, but A. chulabhornae could also be considered for quantitative studies considering its high mean intensity.

Genetic Identification and Technological Potential of Indigenous Lactic Acid Bacteria Isolated from Alheira, a Traditional Portuguese Sausage. Foods 2024; 13:598. [PMID: 38397575 PMCID: PMC10888191 DOI: 10.3390/foods13040598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 02/07/2024] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
Alheira is a naturally fermented meat sausage traditionally made in the Portuguese region of Trás-os-Montes. Lactic acid bacteria (LAB) are the dominant microorganisms in alheira and can endow it with various technological properties. This study aimed (1) to characterize technological features and in vitro antimicrobial activity of LAB isolated from alheira, and (2) to reveal associations between such phenotypic characteristics and the isolates species identified through amplification and sequencing of the 16S ribosomal gene. Sixty-two LAB isolates were identified and Enterococcus (E.) faecium corresponded to 32.3% of isolates, followed by Leuconostoc (L.) mesenteroides (19.4%) and Latilactobacillus (Lb.) sakei (17.7%), aligning with previous research on traditional Portuguese fermented meat sausages. The phenotypic analysis of LAB isolates indicated diverse acidification capacities, proteolytic activities, and inhibitory effects against foodborne pathogens Listeria (L.) monocytogenes, Salmonella (S.) Typhimurium and Staphylococcus (S.) aureus. Overall, lactobacilli displayed high inhibition activity against the pathogens S. aureus, L. monocytogenes, and S. Typhimurium. Although the mechanisms for the inhibition of pathogen growth need to be further elucidated, these findings enhance our understanding of LAB diversity and functionality in alheira sausages, contributing to product safety and quality.

A metagenomic survey of bacterial communities from kurut: The fermented cow milk in Kyrgyzstan. Chem Biodivers 2024; 21:e202301374. [PMID: 38230544 DOI: 10.1002/cbdv.202301374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 01/13/2024] [Accepted: 01/16/2024] [Indexed: 01/18/2024]
Abstract
Kurut is a traditional dry dairy product mostly consumed in Central Asia. In this study, the distribution of the dominant bacteria present in kurut samples (n=84) originated from seven (Chuy, Issyk-Kul, Talas, Naryn, Jalal-Abad, Osh, and Batken) regions in Kyrgyzstan were analyzed with Illumina iSeq100 platform. The dominant phylum detected was Firmicutes followed by Proteobacteria, Actinobacteria, Cyanobacteria/Chloroplast, and Tenericutes. The most abundant family detected was Lactobacillaceae followed by Streptococcaceae, Enterococcaceae, Chloroplast, and Leuconostocaceae. At the genus level, Lactobacillus was the predominant one in samples and Streptococcus, Enterococcus, Lactococcus, and Streptophyta followed this. Further comprehensive characterization analyses in kurut samples may have potential applications both in industrial starter culture developments and also future therapeutic approaches based on potential strains with probiotic properties.

Abstract
Iodine is essential for human health, and dietary iodine sources are critical. Living isolated on islands in the North Atlantic Ocean fostered unique dietary traditions in the Faroe Islands. The dietary peculiarities led us to collect and measure the iodine content of local foods and beverages and calculate daily iodine intakes based on four Faroese dietary scenarios. Marine foods and birds had iodine contents from 300 µg/kg and up, markedly higher than dairy, grains, terrestrial, vegetables, and liquid foods (p<0.001). Vegetables and beverages contained negligible iodine. Wind-dried fermented lamb meat iodine content varied by 100% depending on whether it was herded on an island with beaches (105 µg/kg) or with cliffs (53 µg/kg) facing the ocean. The daily iodine intake varied from around 50 µg to just over 200 µg with diets rich in fish and whales. In conclusion, the traditional diet has been a critical source of iodine on the Faroe Islands. The Faroese may be iodine replete with traditional diets but face the risk of iodine deficiency with dietary transition towards a more western diet. Locally produced Faroese foods are therefore relevant to promote health, and may additionally support food security, local involvement and knowledge, and long-term sustainability.

Abstract
Traditional foods (TFs) hold increasing global relevance due to their potential to address health and dietary challenges. This study explores TF consumption and patterns in a middle-income country's general population. Using 2017 Ecuadorian highlands survey data, we identified four consumption clusters with distinct TF preferences. Chi-square tests identified variations in independent variables across clusters. Poisson regression models highlighted city, age, education, and food habits as independent predictors of TF-based clusters. Our findings broaden TF importance to nutrition beyond specific populations. Understanding consumption patterns and socioeconomic links supports nuanced public health strategies to tackle contemporary health, social equity, and sustainability issues.

Factors Affecting the Consumption of Traditional Food in Tourism-Perceptions of the Management Sector of Catering Facilities. Foods 2023; 12:2338. [PMID: 37372549 DOI: 10.3390/foods12122338] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/01/2023] [Accepted: 06/03/2023] [Indexed: 06/29/2023] Open
Abstract
The topic of this study is the factors that influence the consumption of traditional food products (TFPs) in tourism, as seen from the perspective of management-sector employees in food and beverage catering facilities. The paper aims to analyse the economic, environmental, social, and touristic factors that highly influence the consumption patterns of catering facilities which are significant providers of traditional gastronomic experiences in tourism, by using the specially designed TFPct scale. The study was conducted on a sample of 300 catering facilities in AP Vojvodina (the Republic of Serbia). An explanatory factor analysis was used to confirm the key factors that influence the consumption of traditional products used to prepare the meals that are a part of what catering facilities offer. Subsequently, a binary logistics regression model was used to establish which of the indicated factors has a statistically significant effect on the management's decision to purchase these products for their catering facility. The study showed that the TFPct scale is appropriate for this type of research, and that economic factors are key factors in the consumption of traditional products. Moreover, compared with other types of catering facilities, interest in the consumption of these products is clearly expressed by a la carte restaurants.

"We Need to Live off the Land": An Exploration and Conceptualization of Community-Based Indigenous Food Sovereignty Experiences and Practices. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:4627. [PMID: 36901638 PMCID: PMC10002046 DOI: 10.3390/ijerph20054627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/02/2023] [Accepted: 03/04/2023] [Indexed: 06/18/2023]
Abstract
Although Indigenous food systems are sustainable in nature, many of these systems have been forcibly altered among Indigenous communities within Canada, as a consequence of colonization. Indigenous Food Sovereignty (IFS) movements work to counteract the dismantling of Indigenous food systems as well as the negative health impacts of environmental dispossession experienced by Indigenous communities. Through community-based participatory research methodologies and the utilization of Etuaptmumk, or two-eyed seeing, this research project explored community perspectives of IFS in Western Canada. Reflexive thematic analysis of qualitative data collected during a sharing circle held with community members identified the influence of Indigenous Knowledge and community support on three main aspects of Indigenous food sovereignty, including (1) environmental concerns, (2) sustainable practices and (3) a strong relationship with the land and waters. Through the sharing of stories and memories related to traditional foods and current sovereignty projects, community members identified concerns for their local ecosystem as well as a desire to preserve its natural state for generations to come. The strengthening of IFS movements is critical to the overall wellbeing of Indigenous communities within Canada. Support is needed for movements that honour relationships with traditional foods and recognize traditional lands and waters as necessary for healing and sustaining the health of Indigenous communities.

Tetracycline Resistance Genes in the Traditional Swedish Sour Herring surströmming as Revealed Using qPCR. Genes (Basel) 2022; 14:genes14010056.

Abstract
Antibiotic resistance (AR) represents a global concern for human health. To the best of the authors' knowledge, no study addressing AR in surströmming, a traditional Swedish fermented herring, has been performed to date. The aim of the present research was to study the prevalence of tet(O), tet(S), tet(W), tet(K), and tet(M) genes encoding for resistance to tetracycline using quantitative PCR (qPCR) applied to ready-to-eat surströmming samples collected from three producers located in Sweden. The tet(M) gene was found in all the analyzed samples, and it was also the most abundant among the tested tet genes; moreover, tet(O) was the least frequently detected gene. As a general trend, all the analyzed samples showed a high occurrence of the target genes, with slight variations among the producers. A principal component analysis did not reveal any separation among the samples or producers. All the collected data allowed for a drawing of a first picture of the occurrence of tetracycline resistance genes in ready-to-eat surströmming samples. Since no differences among the samples manufactured by the different producers were observed, it is likely that the detected genes were homogeneously spread among the microbial species shared by the herrings used as raw materials. Moreover, it can be hypothesized that the presence of the detected genes was also the result of a selective pressure of the natural marine environment on the herrings' gut microbiota and, hence, on the pro-technological microorganisms responsible for the fermentation of surströmming. However, the contribution of the manufacturers to the contamination of the processed herrings cannot be excluded.

Learning Circles: A Collaborative Approach to Enhance Local, Healthy and Traditional Foods for Youth in the Northerly Community of Hazelton/Upper Skeena, British Columbia, Canada. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15878. [PMID: 36497954 PMCID: PMC9737344 DOI: 10.3390/ijerph192315878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/23/2022] [Accepted: 11/24/2022] [Indexed: 06/17/2023]
Abstract
Youth health, long-term food sovereignty and the reclamation of traditional food-related knowledge are areas of concern within Indigenous communities in Canada. Learning Circles: Local Healthy Food to School (LC:LHF2S) built on an exemplar program in four predominantly Indigenous communities. In each, the initiative worked with interested community members to plan, implement and evaluate a range of activities aimed at enhancing access to local, healthy and traditional foods for schools and youth. This case study describes the context, process, outcomes and perceptions of implementation in one of the communities, Hazelton/Upper Skeena, located in northern British Columbia. Data were collected between 2016-2019 and included semi-directed interviews with community members and LCEF (n = 18), process reporting (e.g., LCEF reports, emails, conference calls and tracking data), photographs and video footage, and photovoice. Data were analyzed thematically. Hazelton/Upper Skeena has an active local and traditional food culture. Indigenous governance was supportive, and community members focused on partnership and leadership development, gardens, and food skills work. Findings point to strengths; traditional food, knowledge and practices are valued by youth and were prioritized. LC:LHF2S is a flexible initiative that aims to engage the broader community, and exemplifies some of the best practices recommended for community-based initiatives within Indigenous communities. Results indicate that a LC is a feasible venture in this community; one that can facilitate partnership-building and contribute to increased access to local and traditional food among school-aged youth. Recommendations based on community input may help the uptake of the model in similar communities across Canada, and globally.

Abstract
The study recorded the food uses of wild food plants (WFPs) among the Sarikoli diaspora and the dominant Wakhi in Broghil Valley, North Pakistan, to understand their food adaptation, mainly by looking through the lens of food ethnobotanies. A total of 30 participants took part in the study, which included 15 elderly individuals from each ethnic group. Data were gathered through semi-structured interviews. We recorded 29 WFPs, mostly used as cooked vegetables and snacks. The food uses, as well as the local plant nomenclatures, linked to WFPs of the two studied groups were completely homogenized, which could be attributed to the cultural assimilation of the Sarikoli people to Wakhi culture. We found that although traditional knowledge on WFPs has been homogenized, social change in nearby regions is also threatening the traditional knowledge of the two communities, as evidenced by the smaller number of plants reported compared to that of all other field ethnobotanical studies conducted in nearby regions. Moreover, the growth of legal restrictions and sanctions on accessing natural resources are posing serious challenges to cultural resilience in the valley, and the restrictions on cross-border movement in particular are creating challenges for those who have cross-border kinship relationships between the two groups. We suggest specific measures, such as the promotion of food tourism and educational activities, to protect traditional knowledge and bicultural heritage from further erosion in the region.

Abstract
Two years after the onset of the COVID-19 pandemic, many nations and communities continue to grapple with waves of infection and social fallout from pandemic fatigue and frustration. While we are still years away from realizing the full impacts of COVID-19, reflecting on our collective responses has offered some insights into the impact that various public health policies and decisions had on nations' abilities to weather the multifaceted impacts of the pandemic. Widely believed to have the potential to be devastated by COVID-19, many Indigenous communities in Canada were extremely successful in managing outbreaks. This paper outlines one such example, Wapekeka First Nation, and the community's formidable response to the pandemic with a specific focus on food mobilization efforts. Built on over a decade of community-based participatory action research and informed by six interviews with key pandemic leaders in the community, this paper, co-led by two community hunters and band council members, emphasizes the various decisions and initiatives that led to Wapekeka's successful pandemic response. Proactive leadership, along with strong traditional harvesting and processing efforts, helped to take care of the community while they remained strictly isolated from virus exposure.

Abstract
A dietary transition away from traditional foods and toward a diet of the predominantly unhealthy market is a public health and sociocultural concern throughout Indigenous communities in Canada, including those in the sub-Arctic and remote regions of Dehcho and Sahtú of the Northwest Territories, Canada. The main aim of the present study is to describe dietary intakes for macronutrients and micronutrients in traditional and market food from the Mackenzie Valley study. We also show the trends of contributions and differences of dietary intakes over time from 1994 data collected and reported by the Centre for Indigenous People’s Nutrition and Environment (CINE) in 1996. Based on 24-h dietary recall data, the study uses descriptive statistics to describe the observed dietary intake of the Dene First Nations communities in the Dehcho and Sahtú regions of the NWT. Indigenous people in Canada, like the sub-Arctic regions of Dehcho and Sahtú of the NWT, continue to consume traditional foods, although as a small percentage of their total dietary intake. The observed dietary intake calls for action to ensure that traditional food remains a staple as it is critical for the wellbeing of Dene in the Dehcho and Sahtú regions and across the territory.

Abstract
Wild food plants (WFPs) have been an important source of human nutrition since ancient times, and it particularly revives when conventional food is not available due to emergency situations, such as natural disasters and conflicts. The war in Syria has entered 10 years since it started in 2011, and it has caused the largest war-related crises since World War II. Nearly 60% of the Syrian population (12.4 million people) are food-insecure. WFPs are already culturally important in the region, and may be supplementing local diets during this conflict. Our study aimed to uncover the conflict’s effect on the use of WFPs and to know what species are consumed by local people during the current crisis. The fieldwork was carried out between March 2020 and March 2021 in the Tartus governorate located in the coastal region of Syria. Semi-structured interviews were conducted with 50 participants (26 women and 24 men) distributed in 26 villages along the study area. We recorded the vernacular names, uses, plant parts used, modes of preparation and consumption, change in WFP use before and during the conflict, and informants’ perceptions towards WFPs. We documented 75 wild food plant species used for food and drink. Almost two-thirds (64%) of informants reported an increase in their reliance on wild plants as a food source during the conflict. The species of Origanum syriacum, Rhus coriaria, Eryngium creticum, and Cichorium intybus were among the most quoted species by informants. Sleeq (steamed leafy vegetables), Zaatar (breakfast/dinner food), and Louf (soup) were the most popular wild plant-based dishes.

Abstract
Flatbreads are traditional food products of ancient origin, still produced and appreciated in their original locations and beyond, having spread through historical and modern migration. While the history and preparation of Somali flatbread, known as canjeero in southern regions and laxoox in northern regions, has been shared orally for generations among the women who cook it at home, it has not been the object of scientific studies. An in-field study was therefore carried out in various cities in Somalia, Somaliland, and Ethiopia’s Somali State to document the formulation, production methods, and consumption patterns of this Somali flatbread. Laxoox /canjeero production was found to be relatively homogenous, but the data revealed two significant divergences: in bread formulation and in the procedure for structure development. These divergences result from disparities in the mechanization of bread production between rural and urban, and from the destruction of infrastructure, including food processing machines in public markets, leading up to the Somali civil war. An original framework of four production styles (“heritage,” “new heritage,” “innovative,” and “global”) illustrates these divergences in detail. Heritage production is linked to the historic era of nomadic Somali pastoralism, while the other three styles originated in civil conflict and continue today.

Abstract
The tradition of making fermented foods and beverages in Iraq dates back to 7500 BC. These fermented foods and beverages are represented by meat-, milk-, vegetable-, and fruit-based products reflecting diversity of agricultural production in ancient Iraq (Mesopotamia). Although the recipes for some fermented foods and beverages were lost throughout history, those remaining foods and beverages occupy a noticeable position in modern Iraqi cuisine. In this review, knowledge and techniques for preparation of 5 traditional fermented foods, i.e. Basturma, Smoked Liban,Aushari cheese, Turshi, and Sour Khobz, and 3 fermented beverages, i.e. Shanina, Sharbet Zbeeb, and Erk Sous in Iraq, are documented. Traditional fermented foods and beverages have multiple health benefits because of high content of probiotics and bioactive compounds. Traditional fermented foods and beverages are made using the back-slopping technique which ensures safety of production and maintains organoleptic properties. The review highlights the potential of fermented foods and beverages for their large-scale commercialization.

Abstract
Wild game consumption has been associated with health benefits but the acute influence on human protein metabolism remains unknown. We compared feeding-induced responses of equivalent amounts of free-range reindeer (FR) and commercial beef (CB) on protein kinetics using stable isotope methodology. Seven participants (age: 40 ± 14 years; body mass index: 24 ± 3 kg/m2) completed two randomised studies, ingesting 2 oz of FR or CB. L-[ring 2H5]phenylalanine & L-[ring 2H2]tyrosine were delivered via primed, continuous intravenous infusion. Blood samples were collected during the basal period and following consumption of FR or CB. Feeding-induced changes in whole-body protein synthesis (PS), protein breakdown (PB), and net protein balance (NB) were determined via plasma sample isotope enrichment analysis by gas chromatography-mass spectrometry; plasma essential amino acid (EAA) concentrations were determined by liquid chromatography-electrospray ionisation-mass spectrometry. Plasma post-prandial EAA concentrations were higher with FR compared to CB (P < 0.05). The acute feeding-induced PS response was not different, but PB was reduced and contributed to a superior level of NB (P < 0.00001) in FR compared to CB. Our results demonstrate that FR may influence more favourable protein metabolism than CB. These data support potential health benefits of wild game onf whole-body protein.Abbreviations: BMI: body mass index; DIAAS: digestible indispensable amino acid score; CB: commercial beef; EAA: essential amino acids; FR: free-range reindeer; Ra: rate of appearance; UAF: University of Alaska Fairbanks; USDA: USA Department of Agriculture.

[PMID: 34834883 PMCID: PMC8623271 DOI: 10.3390/plants10112520] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 11/12/2021] [Accepted: 11/17/2021] [Indexed: 05/16/2023]
Abstract
The home garden is a unique human-nature interspace that accommodates a diverse spectrum of plant species and provides multiple services to households. One of the most important roles of home gardens is to shelter the agricultural plant diversity that provides for diverse and healthy nutrition, especially in rural communities. While tropical home gardens have received wide recognition due to their provisional function for the local communities, temperate and especially European home gardens have been discussed less frequently as a source of subsistence. The main objectives of the current study were to document plant species grown in Bulgarian rural home gardens and to explore related local knowledge and cultural practices that influence food plant diversity, its selection and preservation. Field work was focused on settlements situated in eight provinces in South and North-West Bulgaria. Participants representing 65 home gardens were approached through semi-structured interviews. Home gardens were found to harbor 145 cultivated and semi-cultivated plant taxa, used as food, medicinal and aromatic plants and as animal fodder. Members of the Rosaceae family were most numerous. The largest part of the garden area was occupied by vegetable crops of Solanaceae and Cucurbitaceae. In 63.1% of the studied households, the food growing area comprised more than 2/3 of the total size of the garden. Most preferred crops reflected the social and cultural importance of food self-provisioning, especially in the rural areas. The provisional role of the home gardens in regard to preparation of traditional foods and the driving forces for seed saving are discussed.

Phytochemical Composition, Antibacterial Activity, and Antioxidant Properties of the Artocarpus altilis Fruits to Promote Their Consumption in the Comoros Islands as Potential Health-Promoting Food or a Source of Bioactive Molecules for the Food Industry. Foods 2021; 10:foods10092136. [PMID: 34574246 PMCID: PMC8468414 DOI: 10.3390/foods10092136] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 08/30/2021] [Accepted: 09/02/2021] [Indexed: 12/03/2022] Open
Abstract
The present study aimed to evaluate the health-promoting potential of breadfruit (Artocarpus altilis (Parkinson) Fosberg, Moraceae family), a traditional Comorian food, considering the sample variability according to geographic localisation. Moreover, the main aims of this research were also to promote its consumption in the Comoros Islands as potential health-promoting food and evaluate it as a source of bioactive molecules for the food industry thanks to its antioxidant and antibacterial properties. Investigations on biologically active substances were carried out on the extracts obtained from breadfruit flours from five regions of Grande Comore (Ngazidja), the main island in Comoros. Phytochemical screening revealed the presence of tannins and polyphenols, flavonoids, leucoanthocyanins, steroids, and triterpenes. The considered secondary metabolites were phenolic compounds, vitamin C, monoterpenes, and organic acids. The contents of total phenolic compounds (mgGAE/100 g of dry weight—DW) in the extracts ranged from 29.69 ± 1.40 (breadfruit from Mbadjini—ExMBA) to 96.14 ± 2.07 (breadfruit from Itsandra—ExITS). These compounds included flavanols, flavonols, cinnamic acid and benzoic acid derivatives, and tannins which were detected at different levels in the different extracts. Chlorogenic acid presented the highest levels between 26.57 ± 0.31 mg/100 g DW (ExMIT) and 43.80 ± 5.43 mg/100 g DW (ExMBA). Quercetin was by far the most quantitatively important flavonol with levels ranging from 14.68 ± 0.19 mg/100 g DW (ExMIT) to 29.60 ± 0.28 mg/100 g DW (ExITS). The extracts were also rich in organic acids and monoterpenes. Quinic acid with contents ranging from 77.25 ± 6.04 mg/100 g DW (ExMBA) to 658.56 ± 0.25 mg/100 g DW of ExHAM was the most important organic acid in all the breadfruit extracts, while limonene was quantitatively the main monoterpene with contents between 85.86 ± 0.23 mg/100 g DW (ExMIT) and 565.45 ± 0.24 mg/100 g DW (ExITS). The antibacterial activity of the extracts was evaluated on twelve pathogens including six Gram (+) bacteria and six Gram (−) bacteria. By the solid medium disc method, except for Escherichia coli and Pseudomonas aeruginosa, all the bacteria were sensitive to one or more extracts. Inhibitory Halo Diameters (IHDs) ranged from 8 mm to 16 mm. Salmonella enterica, Clostridium perfringens, and Vibrio fischeri were the most sensitive with IHD > 14 mm for ExITS. By the liquid microdilution method, MICs ranged from 3.12 mg/mL to 50 mg/mL and varied depending on the extract. Bacillus megaterium was the most sensitive with MICs ≤ 12.5 mg/mL. Pseudomonas aeruginosa, Shigella flexneri, and Vibrio fischeri were the least sensitive with all MICs ≥ 12.5 mg/mL. ExHAM was most effective with a MIC of 3.12 mg/mL on Staphylococcus aureus and 6.25 mg/mL on Salmonella enterica. The antioxidant power of the extracts was evaluated by the FRAP method. The activity ranged from 5.44 ± 0.35 (ExMBA) to 14.83 ± 0.11 mmol Fe2+/kg DW (ExHAM). Breadfruit from different regions of Comoros contained different classes of secondary metabolites well known for their important pharmacological properties. The results of this study on phenolics, monoterpenes, and organic acids have provided new data on these fruits. The obtained results showed that breadfruit from the biggest island of the Union of Comoros also presented antimicrobial and antioxidant properties, even if some differences in effectiveness existed between fruits from different regions.

Gathered Wild Food Plants among Diverse Religious Groups in Jhelum District, Punjab, Pakistan. Foods 2021; 10:foods10030594. [PMID: 33799901 PMCID: PMC7999103 DOI: 10.3390/foods10030594] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 02/22/2021] [Accepted: 03/04/2021] [Indexed: 12/15/2022] Open
Abstract
Recent ethnobotanical studies have raised the hypothesis that religious affiliation can, in certain circumstances, influence the evolution of the use of wild food plants, given that it shapes kinship relations and vertical transmission of traditional/local environmental knowledge. The local population living in Jhelum District, Punjab, Pakistan comprises very diverse religious and linguistic groups. A field study about the uses of wild food plants was conducted in the district. This field survey included 120 semi-structured interviews in 27 villages, focusing on six religious groups (Sunni and Shia Muslims, Christians, Hindus, Sikhs, and Ahmadis). We documented a total of 77 wild food plants and one mushroom species which were used by the local population mainly as cooked vegetables and raw snacks. The cross-religious comparison among six groups showed a high homogeneity of use among two Muslim groups (Shias and Sunnis), while the other four religious groups showed less extensive, yet diverse uses, staying within the variety of taxa used by Islamic groups. No specific plant cultural markers (i.e., plants gathered only by one community) could be identified, although there were a limited number of group-specific uses of the shared plants. Moreover, the field study showed erosion of the knowledge among the non-Muslim groups, which were more engaged in urban occupations and possibly underwent stronger cultural adaption to a modern lifestyle. The recorded traditional knowledge could be used to guide future development programs aimed at fostering food security and the valorization of the local bio-cultural heritage.

Inuit Country Food and Health during Pregnancy and Early Childhood in the Circumpolar North: A Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18052625. [PMID: 33807905 PMCID: PMC7967653 DOI: 10.3390/ijerph18052625] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 02/18/2021] [Accepted: 02/18/2021] [Indexed: 02/08/2023]
Abstract
Inuit communities in the Circumpolar North have experienced a nutrition transition characterized by the decreased intake of culturally important, nutrient-rich traditional food (country food), and an increased intake of market food, resulting in concerns over reduced diet quality and emerging chronic diseases. Nutrition in early life is critical for development, may influence health risks in later life, and is an important concern for Inuit community health. The goal of this scoping review was to characterize the nature, extent, and range of the published literature on Inuit country food and health in pregnancy and childhood. A search string was developed and applied to three databases, followed by title and abstract screening and full text review. Articles published between 1995 and 2019 were included, and data were extracted and summarized descriptively. The number of articles generally increased over time, despite the unequal geographic distribution of articles. The majority of the articles focused on environmental contaminants, and one-quarter described nutrient adequacy. Few articles described food security or food safety in pregnancy, and the most utilized quantitative methods. Gaps in understanding of country food use in pregnancy and early childhood highlight areas of future research to support public health policy for this population. Given the critical role of good nutrition in early life and the important contribution country food makes to diet quality for Inuit, further understanding of this interface is warranted.

Ethno-essentialisms of the self: A critique of the cultural scripting of obesity in Japan. SOCIOLOGY OF HEALTH & ILLNESS 2021; 43:796-811. [PMID: 33682921 DOI: 10.1111/1467-9566.13256] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 12/31/2020] [Accepted: 02/03/2021] [Indexed: 06/12/2023]
Abstract
In challenging the 'validity' of the body mass index (BMI), the construct of metabolic syndrome has been used to comprehend how obesity affects Japanese people. This article is grounded in an adaptation of the 'sexual scripting theory' (Gagnon and Simon, 2005) and proposes the concept of 'ethno-essentialisms of the self' to explore the cultural scripts underpinning the development of metabolic syndrome. Ethno-essentialisms of the self indicate a dialectical relationship between a Japanese healthy self and a non-Japanese unhealthy Other, where ethno-racial susceptibilities might make a Japanese self prone to develop metabolic-related diseases. Despite these susceptibilities, Japanese 'biopedagogy' (Wright, 2009) to control bodyweight is oriented by a proper daily calculation of food consumption in relation to calorie-burning. Biopedagogy in the form of food and nutrition education has largely translated into unyielding efforts to (re)traditionalise eating habits to prevent the supposed Westernisation of Japanese food. Overall, medical knowledge serves to propagate ethno-essentialisms of the self, whose unintended consequence could be 'clinical iatrogenic disease' (Illich, 1976).

Market Opportunities for Hay Milk: Factors Influencing Perceptions among Italian Consumers. Animals (Basel) 2021; 11:ani11020431. [PMID: 33562364 PMCID: PMC7915989 DOI: 10.3390/ani11020431] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 01/17/2021] [Accepted: 01/30/2021] [Indexed: 11/16/2022] Open
Abstract
Central and South Italy are characterized by small-scale dairy farms and growing abandonment by farmers for other, better-paid, off-farm jobs. New marketing concepts for milk can be one solution to remunerate mountain farmers for their efforts. This study investigates the potential market for hay milk in Italy. In particular, we want to understand which variables drive the people's willingness to consume hay milk, and if the European food quality certification schemes impact on people's willingness to consume milk from hay-fed cows. Data were collected from a sample of consumers from Central and South Italy (n = 331) using a web-based survey. Later, a discrete choice probit model was applied. The main results indicate that aspects as curiosity, the production place of food, the local culinary traditions, label, and environmental issues play an important role in the people's consumption intentions for milk from hay-fed cows. Moreover, the survey highlights that the respondents had positive opinion towards hay milk and highlighted some important marketing implications for the Italian milk sector. The study findings could encourage discussion about a niche market to boost local growth, initiating a process of improving livelihoods, certification of products, and use of the marketing tools addressed towards a specific milk consumer's profile. In other words, the study could provide useful implications for food manufacturers and facilitate the design of marketing strategies for hay milk produced in Central and South Italy.

Exploring the Resource Value of Transvaal Red Milk Wood ( Mimusops zeyheri) for Food Security and Sustainability: An Appraisal of Existing Evidence. PLANTS 2020; 9:plants9111486. [PMID: 33158124 PMCID: PMC7694233 DOI: 10.3390/plants9111486] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 10/27/2020] [Accepted: 10/29/2020] [Indexed: 11/16/2022]
Abstract
Many African countries are endowed with rich biodiversity with enormous nutritional and economic prospects, but the majority of these resources are not fully harnessed. Exploring these neglected resources, for example, the Transvaal red milkwood tree [(Mimusops zeyheri) Sond. family: Sapotaceae] is of paramount importance for food and nutritional security as well as economic prosperity. This review provides a critical appraisal of the nutritional and health benefits as well as the economic potential of Mimusops zeyheri. The plant is known for its diverse uses among rural communities. In folk medicine, the decoction from the bark and leaves of Mimusops zeyheri are used for treating wounds and ulcers, while the root is used as an infusion taken to treat candidiasis and other health issues. The nutritional profile of the fruit tree is similar to popular exotic fruits and richer in vitamin C when compared to guava and orange. Mimusops zeyheri is a rich source of vitamins, protein, and fatty acids. Based on the rich chemical pool, especially in the fruit and seeds, it has the potential to provide an accessible, readily available, and affordable enriched functional food with valuable health benefits. However, the successful exploration of Mimusopszeyheri for food security and sustainability requires multidisciplinary research. This will help achieve the envisaged food-nutrition security and poverty alleviation potential of the plant, especially among local communities.

Abstract
“Yellow curd” (YC) is one of the most popular homemade Persian fermented foods and is consumed by many people. Notwithstanding, no studies are available to date on its nutritional and microbiological composition. In this study, we examined YC samples obtained from different local markets of Sistan and Baluchestan province, Iran. The results of the chemical analyses revealed a homogenous content of protein (13.71% ± 1.07), lipids (4.09% ± 0.73), and carbohydrates (61% ± 2.13) among the samples. By comparing the average mineral content of YC with yogurt, many relevant differences were detected. Apart from the calcium content, which was similar on average to that of YC, all other minerals tested are present in higher amounts in YC than in yogurt. The analysis of the main sugars present (i.e., lactose, galactose and glucose) highlighted relevant differences among samples, indicating that different YC samples contain natural strains with different capabilities to metabolize sugars. The concentration of galactose in YC samples should be taken into consideration by galactose intolerant people. From the microbiological perspective, the metagenomics analysis revealed that lactic acid bacteria, and particularly the genera Lactobacillus, Pediococcus, and Streptococcus, were dominant in YC. The information provided shows that YC is an interesting base for the preparation of novel functional foods with a good content of beneficial bacteria.

Abstract
INTRODUCTION AND OBJECTIVE Acrylamide (AA) is a carcinogenic and genotoxic food contaminant occurring in carbohydrate-rich foods produced at high cooking temperatures. The aim of the study was to determine the importance of AA exposure with respect to traditional food and to assess the associated risks. MATERIAL AND METHODS 165 food samples were collected from local markets in Lesser Poland. The participants enrolled in the study were 500 residents: (males - 179, females - 321) who had purchased food from local markets. Exposure of the participants to AA was assessed by combining the analytical AA results with data on the individual consumption of traditional foods. Risk assessment of AA exposure from traditional foods was estimated and the margin of exposure (MOE) values were calculated. RESULTS The highest mean AA level was measured in pretzels (92 µg kg -1), followed by bagels (74.81 µg kg-1) and pork paté (59.56 µg kg-1). The average and 95th percentile values of AA exposure were 0.213 and 0.458 [µg kg-1 body weight (BW) day-1]. The calculated values of MOE for the average [798 and 2,019 for both benchmark dose lower confidence limit (BMDL) 0.17 and 0.43 mg kg-1 BW day-1] and 95th percentile AA exposure values (371 and 939 for both BMDL 0.17and 0.43 mg kg -1 BW day-1) suggest that there is a health concern with respect to adult residents. CONCLUSIONS The results of the study confirm the general recommendation to the consumers, especially certain population groups, to eat a balanced healthy diet and to limit the amount of baked cereal products and fried products.

Abstract
BACKGROUND Over the past several decades, rural and indigenous populations in Latin America have experienced abrupt and profound transformations in their lifestyles and economies, many having remarkable health consequences. Yet, these changes have had heterogeneous effects on the population's biology in different local contexts. OBJECTIVES The primary goal was to characterize the nutrition transition and biomarkers of noncommunicable diseases (NCD) risk in 2 Chilean indigenous populations that have had divergent histories of subsistence strategies (agropastoralism compared with hunter-gathering) in the last few millennia and live in contrasting environments, and to identify context-specific factors driving the nutrition and epidemiological transitions. METHODS One-hundred-and-ninety (90 Pehuenche and 100 Atacameño) participants aged 18-87 y completed demographic, food-frequency, and physical activity questionnaires as well as measurements of some NCD risk biomarkers: blood pressure, weight, height, body fat percentage, waist circumference, blood total cholesterol, HDL cholesterol, triglycerides, and glucose. Framingham risk scores (FRSs) were calculated based on age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, smoking, diabetes status, and hypertension medication. RESULTS Few differences in dietary composition and physical activity patterns were observed between the 2 populations. Multivariate analyses showed no differences between the 2 populations in any of the individual NCD risk biomarkers or FRSs after adjusting for age, sex, time since last meal, food insecurity in childhood, ultraprocessed food consumption, and physical activity. CONCLUSIONS Despite contrasting ecological and historical contexts, the 2 groups are converging into similar processes of market and wage-labor integration and transitioning to a Western diet high in processed and nonlocal foods, although some aspects of their "traditional" foodways are still in practice. The frequency of individuals exhibiting NCD biomarkers "at-risk" is relatively high and corresponds to other populations that have gone through nutrition transition. Furthermore, none of these biomarkers or FRSs differed between the 2 populations, suggesting a homogenization in the NCD risk factors.

Abstract
BACKGROUND Due to the lack of resources in remote Aboriginal communities within the Northern Territory of Australia, Aboriginal people requiring chronic maintenance hemodialysis often must relocate from their home communities to Darwin city permanently to receive ongoing care. This phenomenon can cause distressing isolation from important traditional food, land, and family. OBJECTIVE The aim was to identify the relation to traditional food from an Aboriginal perspective and the enablers and barriers to accessing traditional food post-relocation from remote regions of the Northern Territory, Australia, to the urban city of Darwin. METHODS This was a qualitative study design with a total of 12 Aboriginal participants (4 males, 8 females) receiving ongoing hemodialysis at the Nightcliff Renal Unit. Participants had all relocated from a remote region to Darwin. Interviews were conducted between July and September 2018 in Darwin, Australia. Data interpretation was conducted by an Aboriginal researcher and co-authors with a combined 30 y of experience conducting research with Aboriginal people in a health context. Data analysis comprised an inductive thematic analysis approach with an indigenist knowledge interpretation lens to construct, reaffirm, and protect Indigenous views. RESULTS Traditional food was an important part of participants' identity and strongly connected to social, emotional, spiritual and physical health, and well-being. Access to traditional food post-relocation is associated with enablers and barriers including mobility, local knowledge, social support networks, commercial access, and economics. CONCLUSIONS Dialysis patients who are dislocated from remote Aboriginal communities to Darwin experience clear disruption to traditional food access, consumption, availability, and knowledge dissemination to the younger generations.

Abstract
In Canada, store-bought food constitutes the majority of First Nations (FN) people’s diets; however, their traditional foods (TF; wild fish, game, fowl, and plants) remains vital for their health. This study compares health indicators and diet quality among 265 Syilx Okanagan adults according to whether or not they reported eating TF during a 24-h dietary recall. Three methods assessed diet quality: nutrient intakes and adequacy, Healthy Eating Index (HEI-C), and contributions of ultra-processed products (UPP) to %energy using the NOVA classification. Fifty-nine participants (22%) reported eating TF during the dietary recall; TF contributed to 13% of their energy intake. There were no significant differences in weight status or prevalence of chronic disease between TF eaters and non-eaters. TF eaters had significantly higher intakes of protein; omega-3 fatty acids; dietary fibre; copper; magnesium; manganese; phosphorus; potassium; zinc; niacin; riboflavin; and vitamins B6, B12, D, and E than non-eaters. TF eaters also had significantly better diet quality based on the HEI-C and the %energy from UPP. Findings support that TF are critical contributors to the diet quality of FN individuals. Strength-based FN-led interventions, such as Indigenous food sovereignty initiatives, should be promoted to improve access to TF and to foster TF consumption.

Abstract
The densely packed storage of valuable nutrients (carbohydrates, lipids, proteins, micronutrients) in the endosperm of nuts and seeds makes the study of their complex composition a topic of great importance. Ceramides in the total lipid extract of some ground almonds and pistachios were searched with a systematic innovative discovery precursor ion scan in a triple quadrupole tandem mass spectrometry, where iso-energetic collision activated dissociation was performed. Five descriptors were used to search components with different C18 long chain bases containing different structural motifs (d18:0, d18:1, d18:2, t18:0, t18:1). The presence of hexoside unit was screened with a specific neutral loss experiment under iso-energetic collision activated dissociation conditions. The discovery scans highlighted the presence of two specific hexosyl-ceramides with a modified sphingosine component (d18:2) and C16:0 or C16:0 hydroxy-fatty acids. The hexosyl-ceramide with the non-hydroxylated fatty acid seemed specific of pistachios and was undetected in almonds. The fast and comprehensive mass spectrometric method used here can be useful to screen lipid extracts of several more seeds of nutraceutical interest, searching for unusual and/or specific sphingosides with chemically decorated long chain bases.

The Nitrogen Isotope Ratio Is a Biomarker of Yup'ik Traditional Food Intake and Reflects Dietary Seasonality in Segmental Hair Analyses. J Nutr 2019; 149:1960-1966. [PMID: 31268149 PMCID: PMC6825821 DOI: 10.1093/jn/nxz144] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 05/29/2019] [Accepted: 06/04/2019] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND The nitrogen isotope ratio (NIR) is a promising index of traditional food intake for an Alaska Native (Yup'ik) population, which can be measured in blood and hair. However, the NIR has not been calibrated to high-quality measures of Yup'ik traditional food intake. OBJECTIVES Our primary objective was to examine associations between intakes of Yup'ik traditional food groups, including fish, marine mammals, birds, land mammals, berries, greens, and total traditional foods, and the NIR. In an exploratory analysis, we also examined whether NIR analyzed sequentially along hair could reflect dietary seasonality. METHODS We recruited 68 participants from 2 Yup'ik communities in the Yukon Kuskokwim region of Southwest Alaska (49% female, aged 14-79 y). Participants completed 4 unscheduled 24-h food recalls over the period peak of RBC and hair synthesis preceding a specimen collection visit. The NIR was measured in RBCs ( n = 68), a proximal hair section (n = 58), and sequential segments of hair from individuals in the upper 2 quartiles of traditional food intake having hair >6 cm in length, plus 2 low subsistence participants for reference (n = 18). Diet-biomarker associations were assessed using Pearson's correlation and linear regression. RESULTS Intakes of fish, marine mammals, berries, and greens were significantly associated with the NIR. The strongest dietary association was with total traditional food intake (R2 = 0.62), which indicated that each 1‰ increase in the RBC NIR corresponded to 8% of energy from traditional foods. Hair NIR appeared to fluctuate seasonally in some individuals, peaking in the summertime. CONCLUSIONS Findings support the use of the RBC and hair NIR to assess total traditional food intake in a Yup'ik population. Analyses of sequential hair NIR provided evidence of seasonality in traditional food intake, although seasonal variations were modest relative to interindividual variation.

Traditional Sheep Consumption by Navajo People in Cameron, Arizona. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16214195. [PMID: 31671510 PMCID: PMC6862166 DOI: 10.3390/ijerph16214195] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 10/23/2019] [Accepted: 10/25/2019] [Indexed: 11/17/2022]
Abstract
Over 500 abandoned uranium mines are located on the Navajo Reservation. Different pathways of environmental uranium exposure have been studied with respect to the Navajo people including water, soil, and plants; however, uranium exposure from traditional Navajo food, specifically mutton (sheep), has not been reported. This study focuses on mutton consumption in the small community of Cameron, Arizona, located in the southwestern region of the Navajo Nation and initiated after community members expressed concern with the uranium exposure of their sheep. Preliminary investigation into the presence of uranium in sheep raised near Cameron showed elevated uranium levels in the kidneys the sheep tested. The goal of this study is to investigate mutton consumption among the Navajo living in Cameron. Mutton is a traditional food of the Navajo, but consumption practices are not well documented. An important aspect of determining the extent of exposure through food consumption is to assess the frequency of consumption. The results of this study indicate the Cameron participants consume mutton most commonly at family gatherings or celebrations. The survey suggests that less mutton is consumed now compared to the past, and there is concern that contaminated mutton may change traditional ceremonies.

Abstract
The food supply chain has been recognised by the EU as a critical infrastructure, and its complexity is the main cause of vulnerability. Depending on the food matrix, natural and/or deliberate contamination, food-borne diseases or even food fraud incidents may occur worldwide. Consequently, robust predictive models and/or software tools are needed to support decision-making and mitigating risks in an efficient and timely manner. In this frame, the fellow participated in data collection and analysis tasks, so as to provide additional predictive models. The working programme, covered a wide range of aspects related to risk assessment including identification of emerging risks (quantitative), microbiological risk assessment, authenticity assessment, spatio-temporal epidemiological modelling and database formation for hosting predictive microbial models. The training and close integration, in the open-source, in-house (German Federal Institute for Risk Assessment (BfR)) developed software tools under the framework of FoodRisk-Labs (https://foodrisklabs.bfr.bund.de.) for data analysis, predictive microbiology, quantitative microbiological risk assessment and automatic data retrieval purposes allowed for the independent use. Moreover, the fellow actively contributed to the update of the upcoming Yersinia enterocolitica risk assessment, and also in authenticity assessment of edible oils. Over the course of the year, the fellow was closely involved in international and national research projects with experts in the above-mentioned disciplines. Lastly, he consolidated his acquired knowledge by presenting his scientific work to conferences, and BfR-internal meetings.

Abstract
Bone mineral density (BMD) and fracture risk are elevated in adults with impaired fasting glucose (IFG) or type 2 diabetes mellitus (T2D). This study aimed to compare bone health among Inuit women with IFG, T2D and normoglycemia. The study included Inuit women (≥40 y) with IFG (n = 57), T2D (n = 72) or normoglycemia (n = 340) from the International Polar Year Inuit Health Survey 2007-2008 in Canada. Distal one-third forearm BMD (FaBMD) was measured using a peripheral instantaneous x-ray imager. Anthropometry, fasting plasma glucose (FPG), serum adiponectin, leptin and 25-hydroxyvitamin D (25(OH)D) were measured. Traditional food intakes were surveyed. Data were analysed using mixed model ANOVA and regression models. The median age was 53 (IFG: IQR 48, 67) y and 56 (T2D: IQR 49, 63) y. Compared to normoglycemic women, FaBMD and T-scores were significantly lower in women with T2D, but not with IFG. Frequency of marine mammal intakes (ß = 0.145; 95%CI: 0.018, 0.053, p = 0.0001) positively related to FaBMD. The odds ratio of having a T-score consistent with osteoporosis was lower among women with T2D and higher BMI, while aging increased the risk. Although T2D associates with lower BMD among Inuit women, risk of osteoporosis is tempered, possibly by maintenance of a traditional lifestyle.

Abstract
OBJECTIVE In remote, Alaska Native communities, traditional foods remain a significant source of essential nutrients and appear to protect against the development of chronic diseases. Relatively low intake of traditional foods among Alaska Native children is therefore of concern. The aim of this study was to identify household and parental predictors of child traditional food (TF) consumption and weight in remote Yup'ik communities of Alaska. DESIGN Children (10-18 years old) and parents in two communities (populations <500) were invited to participate in this cross-sectional study. Intake of traditional foods among children and parents was estimated from two-24 h recalls using NDS-R. Weight and height were measured and BMI calculated. Sociodemographic factors, including income and education, were collected from parents. A partial least square path modeling analysis and bootstrapping were performed to identify predictors of child TF consumption and weight. RESULTS Parental intake of traditional foods, Yup'ik identity and income were positively associated with child intake of traditional foods. Further, parental intake of traditional foods predicted lower child BMI. Parental education was negatively associated with child traditional food intake and positively associated with child BMI. CONCLUSIONS Findings suggest that interventions targeting parents may be an effective strategy to increase intake of traditional foods and improve diet quality among Alaska Native youth.

Abstract
Since 2004, research has been conducted in the Ainu Indigenous community of the Saru River Region of Biratori in Northern Japan examining traditional food use knowledge. The purpose was to improve the socio-cultural environment for the Ainu People by implementing interventions meant to reintroduce traditional Ainu food use, so that they can live with dignity and in harmony with non-Ainu people in the heterogeneous community where Japanese cultural values dominate. Ten years after the start of this research, a series of interviews was conducted with Ainu mothers and daughters active in the community to evaluate the result of the interventions because, in accordance with culturally established Ainu gender roles, the Ainu women prepare the Ainu dishes. The interviews indicated that the community of both Ainu and non-Ainu people shared traditional Ainu food as a communal food at community events organized by the Ainu members of the community. The people in the community now identify traditional Ainu dishes with Ainu names, indicating the establishment of culinary and linguistic boundaries between Ainu traditional food and mainstream Japanese food. This also signals that the Ainu People have begun to establish a basis for reconstructing their unique ethnic identity, once suppressed by the government's former assimilation policy.

Abstract
Traditional knowledge and practice of Indigenous Peoples related to their food use and well-being is a wealth of information for academic study and for public health nutrition. Despite unique long-evolved heritages of knowledge of ecosystem resources, Indigenous Peoples comprise 15% of the global poor, but only 5% of the world's population, and they experience poverty, discrimination, and poor nutritional health at far greater rates than mainstream populations in their nations of residence. These disparities are unacceptable in all human rights frameworks, and the call to alleviate them resonates through all human development programmes and the United Nations organizations. The scholars contributing to this special issue of Maternal and Child Nutrition describe how gender roles and the right to food for several cultures of Indigenous Peoples can be fostered to protect their unique foods and traditions, providing food sovereignty and food and nutrition security benefits, especially for women and children. Aspects of societal maternal or paternal lineality and locality, division of labour, spirituality and decision-making are described. These factors structure the impact of gender roles with Indigenous worldviews on the dynamics of family food access, its availability and use, and the use of local food biodiversity. Cultures of Indigenous Peoples in Ecuador, Nigeria, Thailand, India, Canada, Japan, and Morocco are discussed. This publication is a work of the Task Force on Traditional, Indigenous and Cultural Food and Nutrition of the International Union of Nutritional Sciences.

Abstract
European bird cherry (Prunus padus L.) has been known since the Middle Ages for its medical/food use and high health-promoting value. This study aimed to assess the potential of these fruits as a source of bioactive compounds through the characterization of its physicochemical traits, nutraceutical properties, phytochemical composition via HPLC fingerprint, and antioxidant capacity. Fully ripened fruits of Prunus padus L. (Colorata cv) were collected in mid-July 2017 in Chieri, north-western Italy. The TPC (194.22 ± 32.83 mgGAE/100 gFW) and TAC (147.42 ± 0.58 mgC3G/100 gFW) values were obtained from the analyzed extracts. The most important phytochemical class was organic acids (48.62 ± 2.31%), followed by polyphenols (35.34 ± 1.80%), monoterpenes (9.36 ± 0.64%), and vitamin C (6.68 ± 0.22%). In this research the most important flavonols selected as marker were quercitrin (16.37 ± 3.51 mg/100 gFW) and quercetin (11.86 ± 2.36 mg/100 gFW). Data were reported based on fresh weight. Moreover, fresh fruits showed a mean antioxidant activity value of 17.78 ± 0.84 mmol Fe2+·kg-1. Even though the seeds and leaves contain cyanogenic glycosides, this study showed that these fruits could be a natural source of bioactive compounds with high antioxidant properties, due to the contents of organic and phenolic acids, catechins, and a synergetic effect of vitamin C and flavonoids.

Abstract
Rungia congoensis, a traditional vegetable from Kongo Central area (DR. Congo) was studied for establishing microscopic characters and characterised by chromatographic techniques and their in vitro biochemical activities against ROS production were evaluated in cellular models and on an enzyme, myeloperoxidase (MPO), involved in inflammation. Microscopically leaf can be characterised by non-glandular and glandular trichomes, sinuous anticlinal epidermal cells, diacytic stomata and helical vessels. Methanolic extract displayed high cellular antioxidant activity at the concentrations range of 0.1-10 μg mL-1 and 1-20 μg mL-1 using lucigenin on neutrophils and DCFH-DA on HL 60, respectively. This extract also showed, more efficient effects on extracellular and intracellular ROS production and MPO activity. Antioxidant and anti-inflammatory activities of R. congoensis were significantly higher, positively correlated with their phytochemical constituents such as flavonoids, iridoids and phenolic acids; and could justify their use as traditional vegetable and potent local nutraceutical resource.

Abstract
BACKGROUND During past decades the formerly active lifestyle in Greenland has become sedentary, and the intake of traditional food has gradually been replaced with imported food. These lifestyle and dietary habits may affect pregnant women. AIM To describe age and regional differences in reproductive factors, lifestyle and diet among Greenlandic pregnant women in their first trimester. METHODS A cross-sectional study during 2013-2015 including 373 pregnant women was conducted in five Greenlandic regions (West, Disko Bay, South, North and East). Interview-based questionnaires on reproductive factors, lifestyle and dietary habits were compared in relation to two age groups (median age ≤28 years and >28 years). RESULTS In total, 72.4% were Inuit, 46.6% had BMI >25.0 kg/m2, 29.0% were smoking during pregnancy and 54.6% had used hashish. BMI, educational level, personal income, previous pregnancies and planned breastfeeding period were significantly higher in the age group >28 years of age compared to the age group ≤28 years of age. In region Disko Bay, 90.9% were Inuit, in region South more had a university degree (37.9%) and region East had the highest number of previous pregnancies, the highest number of smokers during pregnancy and the most frequent intake of sauce with hot meals and fast-food. CONCLUSIONS Overall a high BMI and a high smoking frequency were found. Age differences were found for BMI and planned breastfeeding period, while regional differences were found for smoking and intake of sauce with hot meals and fast-food. Future recommendations aimed at pregnant women in Greenland should focus on these health issues.

Abstract
OBJECTIVE To explore availability, variety and frequency consumption of traditional foods and their role in alleviating food insecurity in remote Aboriginal Australia. METHODS Availability was assessed through repeated semi-structured interviews and consumption via a survey. Quantitative data were described and qualitative data classified. RESULTS Aboriginal and non-Indigenous key informants (n=30 in 2013; n=19 in 2014) from 20 Northern Territory (NT) communities participated in interviews. Aboriginal primary household shoppers (n=73 in 2014) in five of these communities participated in a survey. Traditional foods were reported to be available year-round in all 20 communities. Most participants (89%) reported consuming a variety of traditional foods at least fortnightly and 71% at least weekly. Seventy-six per cent reported being food insecure, with 40% obtaining traditional food during these times. CONCLUSIONS Traditional food is consumed frequently by Aboriginal people living in remote NT. Implications for public health: Quantifying dietary contribution of traditional food would complement estimated population dietary intake. It would contribute evidence of nutrition transition and differences in intakes across age groups and inform dietary, environmental and social interventions and policy. Designing and conducting assessment of traditional food intake in conjunction with Aboriginal leaders warrants consideration.

Abstract
Background n-3 long-chain polyunsaturated fatty acids (LC-PUFAs) from fish are known modulators of cardiometabolic risk factors. Objective To examine fatty acids (FAs) status and the relationship between n-3 LC-PUFA and cardiometabolic risk factors in Cree participants. Design We analyzed data from a cross-sectional study (n=829) conducted in Cree adults (aged 18–74 years) from 7 communities of the James Bay territory of Quebec (Canada) in 2005–2009. Sociodemographic, lifestyle, clinical and anthropometric data were collected. FAs were quantified in red blood cells (RBCs) under fasting conditions. Results A total of 89% of the participants were overweight (with 69% obesity), 33% had hypertriglyceridemia, 44% had low plasma HDL-c and 77% had fasting plasma insulin ≥90 pmol/l. Total n-3 PUFAs accounted for 6% of total FAs and were higher among older participants, while n-6 PUFAs accounted for 31% of total FAs and were higher among younger participants. According to the adjusted multiple linear regression models, n-3 LC-PUFA was associated (p<0.05) with higher total cholesterol, LDL-c and apo B-100, and was also associated (p<0.05) with lower blood glucose. Conclusion Overall, this study showed that n-3 LC-PUFA levels measured in the RBCs of the Cree adults are relatively low and tend towards lower levels among youth. These levels might be insufficient to offset the prevalence of cardiometabolic risk factors.

Abstract
Black pudding, also known as blood sausages or blood pudding, is a kind of meat product made by blood, popular in Asia, Europe, and America. Twenty-five black pudding formulations with varying fat contents of 2.5%, 5%, 10%, 15%, and 20% (w/w) and sodium contents of 0.2%, 0.4%, 0.6%, 0.8%, and 1.0% (w/w) were manufactured. Sensory acceptance and ranking descriptive analyses as well as compositional and physicochemical analyses were conducted. Samples high in sodium (0.6-1.0%) were scored higher in juiciness, toughness, saltiness, fatness, and spiciness. These samples were the most accepted, whereas samples containing 0.2% sodium were the least accepted. Black pudding samples containing 0.6% sodium and 10% fat displayed a positive (P < 0.05) correlation to liking of flavor and overall acceptability. This meets the sodium target level set by the Food Safety Authority of Ireland and shows additionally that a fat reduction in black pudding products is more than achievable.

Abstract
AIMS AND OBJECTIVES To learn about the meaning of traditional food to institutionalised patients with dementia. BACKGROUND Traditional food strengthens the feelings of belonging, identity and heritage, which help persons with dementia to hold on to and reinforce their cultural identity and quality of life. Taste is more cultural than physiological. Dietary habits are established early in life and may be difficult to change. Being served unfamiliar dishes may lead to disappointment and a feeling of being betrayed and unloved. DESIGN AND METHOD The three studies presented have a qualitative design. In-depth interviews of family members and nurses experienced in dementia care were conducted in South Africa and among ethnic Norwegians and the Sami in Norway. Content-focused analysis, hermeneutic in character, was used to enable the exploration of the thoughts, feelings and cultural meaning described. RESULTS Traditional foods created a feeling of belonging and joy. Familiar tastes and smells awoke pleasant memories in patients and boosted their sense of well-being, identity and belonging, even producing words in those who usually did not speak. CONCLUSIONS In persons with dementia, dishes remembered from their childhood may help maintain and strengthen cultural identity, create joy and increase patients' feeling of belonging, being respected and cared for. Traditional food furthermore improves patients' appetite, nutritional intake and quality of life. To serve traditional meals in nursing homes demands extra planning and resources, traditional knowledge, creativity and knowledge of patients' personal tastes. RELEVANCE FOR CLINICAL PRACTICE This study provides insight into culture-sensitive dietary needs of institutionalised patients with dementia. The cultural significance of food for feeling contentment and social and physical well-being is discussed. Besides helping to avoid undernutrition, being served traditional dishes may be very important to reminiscence, joy, thriving and quality of life.

Traps as treats: a traditional sticky rice snack persisting in rapidly changing Asian kitchens. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2015; 11:24. [PMID: 25889115 PMCID: PMC4374397 DOI: 10.1186/s13002-015-0010-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2015] [Accepted: 02/06/2015] [Indexed: 06/04/2023]
Abstract
BACKGROUND An accessory to modern developing economies includes a shift from traditional, laborious lifestyles and cuisine to more sedentary careers, recreation and convenience-based foodstuffs. Similar changes in the developed western world have led to harmful health consequences. Minimization of this effect in current transitional cultures could be met by placing value on the maintenance of heritage-rich food. Vitally important to this is the preservation and dissemination of knowledge of these traditional foods. Here, we investigate the history and functionality of a traditional rice snack cooked in Nepenthes pitchers, one of the most iconic and recognizable plants in the rapidly growing economic environment of Southeast Asia. METHODS Social media was combined with traditional ethnobotanical surveys to conduct investigations throughout Malaysian Borneo. Interviews were conducted with 25 market customers, vendors and participants from various ethnical groups with an in-depth knowledge of glutinous rice cooked in pitcher plants. The acidity of pitcher fluid was measured during experimental cooking to analyze possible chemical avenues that might contribute to rice stickiness. RESULTS Participants identifying the snack were almost all (96%) from indigenous Bidayuh or Kadazandusun tribal decent. They prepare glutinous rice inside pitcher traps for tradition, vessel functionality and because they thought it added fragrance and taste to the rice. The pH and chemical activity of traps analyzed suggest there is no corresponding effect on rice consistency. Harvest of pitchers does not appear to decrease the number of plants in local populations. CONCLUSIONS The tradition of cooking glutinous rice snacks in pitcher plants, or peruik kera in Malay, likely carries from a time when cooking vessels were more limited, and persists only faintly in tribal culture today because of value placed on maintaining cultural heritage. Social media proved a valuable tool in our research for locating research areas and in interviewing respondents, and we endorse its further use in ethnobotanical investigations. Our gathered data urges for the preservation of sustainable, tribal plant use for the prosperity of both health and culture.

Abstract
The present study was conducted to evaluate the lactic acid- and acetaldehyde-producing abilities of lactic acid bacterial species isolated from traditionally manufactured Turkish yogurts using HPLC. The lactic acid bacterial species purified from the yogurts were the 2 most widely used species in industrial yogurt production: Streptococcus thermophilus and Lactobacillus bulgaricus. These bacteria have the ability to ferment hexose sugars homofermentatively to generate lactic acid and some carbonyl compounds, such as acetaldehyde through pyruvate metabolism. The levels of the compounds produced during fermentation influence the texture and the flavor of the yogurt and are themselves influenced by the chemical composition of the milk, processing conditions, and the metabolic activity of the starter culture. In the study, morphological, biochemical, and molecular characteristics were employed to identify the bacteria obtained from homemade yogurts produced in different regions of Turkey. A collection of 91 Strep. thermophilus and 35 L. bulgaricus strains were investigated for their lactic acid- and acetaldehyde-formation capabilities in various media such as cow milk, LM17 agar, and aerobic-anaerobic SM17 agar or de Man, Rogosa, and Sharpe agar. The amounts of the metabolites generated by each strain in all conditions were quantified by HPLC. The levels were found to vary depending on the species, the strain, and the growth conditions used. Whereas lactic acid production ranged between 0 and 77.9 mg/kg for Strep. thermophilus strains, it ranged from 0 to 103.5 mg/kg for L. bulgaricus. Correspondingly, the ability to generate acetaldehyde ranged from 0 to 105.9 mg/kg in Strep. thermophilus and from 0 to 126.9 mg/kg in L. bulgaricus. Our study constitutes the first attempt to determine characteristics of the wild strains isolated from traditional Turkish yogurts, and the approach presented here, which reveals the differences in metabolite production abilities of the wild lactic acid bacteria strains, holds the potential for the selection of the most desirable strains to be used as starters in commercial yogurt manufacture in the future.

[PMID: 24708730 PMCID: PMC4008438 DOI: 10.1186/1746-4269-10-34] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2013] [Accepted: 01/14/2014] [Indexed: 05/20/2023]
Abstract
BACKGROUND There are few publications on the use and diversity of wild leafy vegetables (WLVs) in Morocco. In order to address this gap, we conducted ethnobotanical field work in Taounate, Azilal and El House regions. METHODS Ethnobotanical collections, free listing, qualitative interviews and a 7 day food frequency questionnaire. RESULTS More than 30 species in 23 genera of WLV were identified. Of these 4 had not previously recorded as WLVs used in Morocco in the literature. WLVs were used by 84% of households surveyed in Taounate (N = 61, in March 2005), and were used up to 4 times a week. Qualitative data revealed both positive and negative perceptions of WLVs and detailed knowledge about preparation among women. The greatest diversity of WLV knowledge and use was in the Rif Mountains (Taounate). There was significant variation in nomenclature and salience of WLVs, not only between regions, but also between villages in the same region. Within the same region (or even village) different local names were used for a given species or genus, and different species were identified by the same local name (including species from different botanical families). Data showed greater overlap in knowledge among villages using the same market. CONCLUSION We believe the results suggest that markets are important sites for WLV knowledge transmission.

Peptidoglycan Hydrolases of Local Lactic Acid Bacteria from Kazakh Traditional Food. Cent Asian J Glob Health 2014; 2:94. [PMID: 29805853 PMCID: PMC5960913 DOI: 10.5195/cajgh.2013.94] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Introduction Peptidoglycan (PG) is a major component of the cell wall of Gram-positive bacteria and is essential for maintaining the integrity of the bacterial cell and its shape. The bacteria synthesize PG hydrolases, which are capable of cleaving the covalent bonds of PG. They also play an important role in modeling PG, which is required for bacterial growth and division. In an era of increasing antibiotic-resistant pathogens, PG hydrolases that destroy these important structures of the cell wall act as a potential source of new antimicrobials. The aim of this study is to identify the main PG hydrolases of local lactic acid bacteria isolated from traditional foods that enhance probiotic activity of a biological preparation. Methods Lactococcus lactis 17A and Lactococcus garvieae 19A were isolated from the traditional sausage-like meat product called kazy. They were isolated according to standards methods of microbiology. Genetic identification of the isolates were tested by determining the nucleotide sequences of 16S rDNA. The Republican collection of microorganisms took strains of Lactobacillus casei subsp. Rhamnosus 13-P, L. delbrueckii subsp. lactis CG-1 B-RKM 0044 from cheese, Lactobacillus casei subsp. casei B-RKM 0202 from homemade butter. They used the standard technique of renaturating polyacrylamide gel electrophoresis to detect PG hydrolases activity. Results According to the profiles of PG hydrolase activity on zymograms, the enzymes of Lactococci 17A and 19A in kazy are similar in electrophoretic mobility to major autolysin AcmA, while the lactobacilli of industrial and home-made dairy products have enzymes similar to extracellular proteins p40 and p75, which have probiotic activity. Conclusions Use of peptidoglycan hydrolases seems to be an interesting approach in the fight against multi-drug resistant strains of bacteria and could be a valuable tool for the treatment of diseases caused by these microorganisms in Kazakhstan.

The dimensions of ' traditional food' in reflexive modernity: Norway as a case study. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2013; 93:3455-3463. [PMID: 23893890 DOI: 10.1002/jsfa.6318] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2013] [Revised: 05/31/2013] [Accepted: 07/24/2013] [Indexed: 06/02/2023]
Abstract
BACKGROUND This article aims to better understand the definition(s) of 'traditional' food. The authors discuss and exemplify how this rhetorical concept is used in the specialist literature and in Norwegian public debate. The authors ultimately propose a set of central dimensions of traditional food and their relevance across various discourses. RESULTS After examining the use of the concept 'tradition' in scientific publications, the authors note that it is based on two main axes: time and know-how. These are interwoven in a 'meaning' dimension in the connection between time and culture, but also in a 'place' dimension that is systematically materialised in food. In order to better describe and understand the dynamic that emerges from the interplay of innovation and tradition, the article goes through the broadest use of 'traditional food' in public discourses, in national and regional newspapers, and in consumers' attitudes. There, the concept of 'traditional food' is used for both preserving historic values and renewing sense of identity. CONCLUSION The article can be regarded as an empirical example which elaborates the understanding of tradition in reflexive modernity. It concludes that the concept of traditional food is neither fixed nor finite but is a fluid and energetic concept which, based on the tensions between four central axes, can adapt to the discourses of preservation, moderation and innovation.

Comparative ethnoentomology of edible stinkbugs in southern Africa and sustainable management considerations. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2013; 9:20. [PMID: 23531129 PMCID: PMC3735041 DOI: 10.1186/1746-4269-9-20] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2012] [Accepted: 03/18/2013] [Indexed: 05/10/2023]
Abstract
Insects, such as stinkbugs, are able to produce noxious defence chemicals to ward off predators, nevertheless, some ethnic groups have recipes to render them delicious. We provide an example of edible stinkbugs (Encosternum delegorguei) used by two locally separate ethnic groups in South Africa, the Vhavenda and Mapulana, with a third group, the Bolobedu using them for commercial purposes. Structured interview schedules and observations with 106 harvesters were conducted to determine differences in use, nomenclature and oral history, methods of collection and preparation as well as perceptions pertaining to availability. The stinkbugs’ foul defence chemical and flight response necessitates nocturnal harvesting when the insect is immobilised by cold. The defence chemical stains the skin and affects vision yet protective gear is not worn. Damage to host trees was recorded when harvesters poached from plantations or private land, whereas, in communal-lands, sustainable methods were preferred. The legitimisation of stinkbug harvesting and introduction of a collection funnel could reduce conflicts with managers of plantations and private land. Two methods to remove the defence chemical for increased palatability were used. Preparation methods differed in whether or not water was used and also whether the head was left intact or removed. Stinkbugs have numerous medicinal uses, in particular as a hangover cure. Awareness and optimal use of beneficial insects, such as stinkbugs, in rural areas could lead to a reconsideration of current environmental management strategies, where harvesters act as habitat stewards and clearing, grazing or burning indigenous vegetation is kept to a minimum.
