Variations in Food Safety Concerns, Hygiene Practices, and Purchasing Behaviors During Pandemic Era: What We Learnt from Coronavirus Disease 2019

The purpose of the study is to evaluate the food safety concerns, purchasing behaviors, and hygiene practices of individuals who contracted and did not contract the severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection. A total of 2393 individuals 18-65 years years of age, 760 who contracted and 1633 who did not contract SARS-CoV-2 infection, participated in the study. Participants were administered a questionnaire to assess demographic information, food safety concerns, hygiene practices, purchasing behavior, and fear of the coronavirus disease 2019 (COVID-19). Results indicated that 56.3% of participants expressed concern about food safety, and 67% were concerned about infected individuals while shopping. Participants who did not contract COVID-19 had higher levels of food safety concerns and generally adhered to better hygiene practices such as handwashing, hygienic food preparation, sanitizer use, and cleaning and disinfection practices (p < 0.05). Overall, purchasing behaviors did not significantly differ by the infection status, except for a significant difference in reduced purchase frequency (p < 0.001). In addition, purchasing behavior varied in relation to fear levels (p < 0.05). As the pandemic appears to be increasingly controlled, the insights gained from managing outbreaks might contribute to improved understanding and preparedness for global pandemics and food safety education in the future.

Comparing application methods of reishi mushroom (Ganoderma lucidum) extract in deep-fried meatballs: impact on heterocyclic aromatic amine formation

BACKGROUND

The present research was conducted to investigate the impact of reishi mushroom extract (RME) on the formation of heterocyclic aromatic amines (HAAs) in meatballs. Sample preparations involved applying RME using either the spreading or addition method, with varying concentrations (0%, 0.25%, 0.5%, and 1% of RME), followed by deep-frying at temperatures of 150 and 190 °C for 3 min.

RESULTS

The types and levels of HAAs varied based on the frying temperature, method of extract application, and the extract concentration. Notably, total HAA contents increased with rising the frying temperature (P < 0.01) and varied from undetectable levels to 4.91 ng g-1 across all analyzed meatballs. The addition method was more effective than the spreading method (P < 0.01), and among the concentrations tested 0.25% RME exhibited the highest efficacy in reducing total HAAs (P < 0.05). Furthermore, the addition method inhibited lipid oxidation more efficiently compared to the surface spreading method (P < 0.05).

CONCLUSION

This study demonstrated that RME had mitigating effects on HAAs depending on the concentration and frying conditions in deep-fried meatball samples. © 2024 Society of Chemical Industry.

The relationship between social media addiction and emotional appetite: a cross-sectional study among young adults in Turkey

OBJECTIVE

The present study focused on the relationship between addiction to social media (SM) and emotional appetite in young adults.

DESIGN

Cross-sectional online survey.

SETTING

The Bergen Social Media Addiction Scale (BSMAS) and Emotional Appetite Questionnaire (EMAQ) were used, and the duration and frequency of SM tools usage were analysed.

PARTICIPANTS

Five hundred and twenty-four participants (144 men and 380 women) aged between 18 and 25 years.

RESULTS

The mean of SM usage duration of participants was 3·2 ± 2·2 h per d along with a mean of BSMAS score of 16·1 ± 5·9. Concerning emotional appetite, the mean scores for positive and negative aspects of EMAQ were 4·4 ± 1·9 and 3·1 ± 1·2, respectively. The predominant SM tools were YouTube (92·6 %) and Instagram (90·3 %). Notably, a significant association was observed between SM addiction and the frequency of access to YouTube, Instagram, and Twitter, with addiction levels increasing as access frequency rose (P < 0·01).

CONCLUSION

This study demonstrated a possible relationship between SM addiction and emotional appetite among young adults. However, further research with more prominent participants and a lengthier follow-up duration is necessary to elucidate how SM tools affect eating behaviour.

Propolis extract reduces heterocyclic aromatic amine formation in chicken thigh meat

1. The objective of the present study was to examine the effect of propolis extract on reducing the formation of carcinogenic/mutagenic heterocyclic aromatic amines (HAAs), thereby minimising dietary exposure in human consumers.2. Chicken thigh meat samples were marinated with various concentrations (0%, 0.25%, 0.5% and 1%) of propolis extract, and cooked in a pan at 150°C or 200°C. Proximate composition, pH, lipid oxidation, creatine, creatinine content and twelve HAA levels of samples were analysed.3. Varying levels of IQx (≤35.44 ng/g), MeIQx (≤0.58 ng/g), MeIQ (≤1.60 ng/g), 7,8-DiMeIQx (≤0.83 ng/g), 4,8-DiMeIQx (≤0.75 ng/g), Harman (≤5.54 ng/g), Trp-P-2 (≤1.77 ng/g), PhIP (≤1.61 ng/g) and AαC (≤0.93 ng/g) were quantified in control samples. Total HAA levels ranged between 2.83 and 47.26 ng/g across all samples. Propolis extract decreased the levels of total HAAs by 41.2-89.4% and 49.4-91.4% at 150°C and 200°C, respectively.4. The results demonstrated that propolis extract marination might be an effective strategy to reduce the dietary exposure of HAAs via mitigating their formation in chicken thigh meat.

Effects of trace elements applied to cows in transition period on serum fatty acid profile

The aim of this study was to determine the effects of a trace element solution applied to cows in the transition period on the levels of fatty acids in the transition period. The material of this study consisted of 20 clinically healthy 3-5 year old simental cows kept under the same care and feeding conditions. Pregnant cows used in the study were divided into 2 equal groups with 10 cows in each group. A single dose of 20 ml of a trace element solution was administered intramuscularly to the pregnant cows in the study group 3 weeks before the birth. Blood samples were taken for analysis at the time of trace element administration, the moment of birth and 3 weeks after birth. Serum samples were analyzed using gas chromatography-mass spectrophotometry (GC-MS) device. When the findings of the study were examined, the fatty acid levels determined 3 weeks before the birth in the group in which trace element solution applied were higher compared to the moment of delivery and the period 3 weeks after birth. In the control group, the fatty acid levels determined 3 weeks before the birth increased at the time of delivery, and the fatty acid levels determined 3 weeks after the birth remained higher than the levels determined 3 weeks before the birth. It was concluded that trace element supplementation applied to pregnant cows during the transition period prevented excessive increase in serum fatty acid levels during the transition period.

Adherence to Mediterranean diet and dietary changes according to the fear of COVID-19 during the pandemic: a cross-sectional study

The coronavirus disease 2019 (COVID-19) has led to the implementation of restrictions to reduce transmission worldwide. The restrictions and measures have affected the psychological health and eating habits. The objective of the present study was to evaluate dietary habits, lifestyle changes, adherence to the Mediterranean diet (MD) and fear of COVID-19 in Turkey during the pandemic. A cross-sectional online survey of socio-demographic characteristics, anthropometric measurements, nutrition, physical activity and lifestyle habits was used for data collection. The fear of COVID-19 levels of the participants was determined by the fear of COVID-19 scale (FCV-19S). The Mediterranean Diet Adherence Screener (MEDAS) was used to evaluate participants' adherence to the MD. The differences between the FCV-19S and MEDAS according to gender were compared. Eight hundred and twenty subjects (76⋅6 % women and 28⋅4 % men) were evaluated within the study. The mean of MEDAS (ranged between 0 and 12) was 6⋅4 ± 2⋅1, and almost half of the participants moderately adhered to the MD. The mean of FCV-19S (ranged between 7 and 33) was 16⋅8 ± 5⋅7, while women's FCV-19S and MEDAS were significantly higher than men's (P < 0⋅001). The consumption of sweetened cereals, grains, pasta, homemade bread and pastries of the respondents with high FCV-19S were higher than in those with low FCV-19S. High FCV-19S was also characterized by decreased take-away food and fast food consumption in approximately 40 % of the respondents (P < 0⋅01). Similarly, women's fast food and take-away food consumption decreased more than men's (P < 0⋅05). In conclusion, the respondents' food consumption and eating habits varied according to the fear of COVID-19.

Comparison of plasma and salivary meteorin-like protein levels in patients with newly diagnosed Type-2 diabetes and treated with metformin

OBJECTIVE

The present study compares the plasma and salivary Metrnl levels of patients newly diagnosed with type-2 diabetes who were treated with metformin for three months with those of a healthy volunteer group and immunohistochemically analyzes Metrnl in salivary glands.

PATIENTS AND METHODS

30 healthy volunteers and 30 newly diagnosed type-2 diabetes patients were included in the study. The newly diagnosed diabetes patients were treated with metformin for three months, and the plasma and salivary metformin levels of both groups were measured at baseline and after the three months of metformin treatment in the patient group. Plasma HbA1c, low-density lipoprotein (LDL-C) and Triglyceride (TG) values of all groups were also measured at baseline following three months of metformin treatment. Biopsies were taken from the parotid and submandibular glands and immunohistochemical staining was performed to show Metrnl immunoreactivity.

RESULTS

Plasma Metrnl, HbA1c, LDL-C and TG levels were higher in the newly diagnosed diabetes group than in the other group, and salivary Metrnl levels were higher than in the control group after three months of metrformin treatment. An examination of the immunohistochemical staining of salivary gland biopsies under light microscope revealed Metrnl immunoreactivity in the intralobular and interlobular ducts of the parotid gland, while Metrnl immunoreactivity was observed in the acinar cells in the intralobular striated duct and interlobular ducts in the submandibular gland.

CONCLUSIONS

Plasma Metrnl, HbA1c, LDL-C and TG levels were higher in the newly diagnosed diabetes group than in the other group. Metrnl immunoreactivity was detected in the parotid and submandibular glands. The relationship between Metrnl and DM should be investigated in larger groups.

Effect of olive leaf extract marination on heterocyclic aromatic amine formation in pan-fried salmon

BACKGROUND

In this study, the reducing effects of varying levels of olive leaf extract (0%, 0.25%, 0.5%, 1% and 2%) on the formation of heterocyclic aromatic amines (HAAs) in pan-cooked salmon at 180 and 220 °C were examined.

RESULTS

All salmon samples were analyzed for ten HAAs: IQx, IQ, MeIQx, MeIQ, 4,8-DiMeIQx, 7,8-DiMeIQx, PhIP, AαC, MeAαC and Trp-P-2. The most abundant HAA was MeIQ (≤2.98 ng g^-1 ) followed by Trp-P-2 (≤2.40 ng g^-1 ), MeIQx (≤0.83 ng g^-1 ), IQ (≤0.41 ng g^-1 ), 7,8-DiMeIQx (≤0.29 ng g^-1 ), 4,8-DiMeIQx (≤0.16 ng g^-1 ) and IQx (≤0.06 ng g^-1 ). However, PhIP, AαC and MeAαC were undetectable in all samples. In the control samples, HAAs were found at levels ranging from not detected to 2.40 ng g^-1 . Total HAA content was between 0.81 and 4.03 ng g^-1 . The olive leaf extracts reduced the total HAA levels at all certain concentration levels at 180 °C and the reducing effects were found to be 32.78-77.69%.

CONCLUSION

The current study displayed that olive leaf extracts could be efficient when added in up to 1% concentration prior to cooking for reducing HAA formation without changing organoleptic characteristics of salmon. © 2021 Society of Chemical Industry.

Inhibitory effect of hawthorn extract on heterocyclic aromatic amine formation in beef and chicken breast meat

This study focused on the inhibitory effect of different levels of hawthorn extract (0, 0.5, and 1%) on the formation of heterocyclic aromatic amines (HAAs) in beef and chicken breast cooked by either pan-cooking or oven-cooking. All meat samples were cooked at three different temperatures (150, 200, and 250°C) and the levels of twelve HAAs were assessed (IQ, IQx, MeIQ, MeIQx, 4,8-DiMeIQx, 7,8-DiMeIQx, PhIP, harman, norharman, AαC, MeAαC, and Trp-P-2). Varying levels of IQ (up to 4.47ng/g), IQx (up to 0.69ng/g), MeIQ (up to 0.82ng/g), MeIQx (up to 1.01ng/g), 4,8-DiMeIQx (up to 0.10ng/g), 7,8-DiMeIQx (up to 0.23ng/g), PhIP (up to 0.75ng/g), harman (up to 2.15ng/g), norharman (up to 1.08ng/g), AαC (up to 1.86ng/g), MeAαC (up to 0.48ng/g), and Trp-P-2 (up to 12.88ng/g), were detected. Samples cooked at 150°C had very low amounts of HAAs, and the levels of HAAs increased gradually when the cooking temperature rose from 150 to 250°C. The total HAA content in chicken breast and beef ranged between not detectable to 17.60ng/g, and not detectable to 11.38ng/g, respectively. The inhibitory effects of hawthorn extract at 0.5% and 1% on total HAAs levels were found to be 12-100% and 19-97% in chicken breast, respectively, and 42-100% and 20-35% in beef, respectively. This study demonstrated that hawthorn extracts at 0.5% and 1% could mitigate HAA formation, especially at high cooking temperatures.

Dietary inflammatory index is associated with serum C-reactive protein and protein energy wasting in hemodialysis patients: A cross-sectional study

BACKGROUND/OBJECTIVE

Malnutrition and inflammation are reported as the most powerful predictors of mortality and morbidity in hemodialysis (HD) patients. Diet has a key role in modulating inflammation and dietary inflammatory index (DII) is a new tool for assessment of inflammatory potential of diet. The aim of this study was to evaluate the application of DII on dietary intake of HD patients and examine the associations between DII and malnutrition-inflammation markers.

SUBJECTS/METHODS

A total of 105 subjects were recruited for this cross-sectional study. Anthropometric measurements, 3-day dietary recall, and pre-dialysis biochemical parameters were recorded for each subject. Subjective global assessment (SGA), which was previously validated for HD patients, and malnutrition inflammation score (MIS) were used for the diagnosis of protein energy wasting. DII was calculated according to average of 3-day dietary recall data.

RESULTS

DII showed significant correlation with reliable malnutrition and inflammation indicators including SGA (r = 0.28, P < 0.01), MIS (r = 0.28, P < 0.01), and serum C-reactive protein (CRP) (r = 0.35, P < 0.001) in HD patients. When the study population was divided into three subgroups according to their DII score, significant increasing trends across the tertiles of DII were observed for SGA score (P = 0.035), serum CRP (P = 0.001), dietary energy (P < 0.001), total fat (P < 0.001), saturated fatty acids (P < 0.001), polyunsaturated fatty acids (P = 0.006), and omega-6 fatty acids (P = 0.01) intakes.

CONCLUSION

This study shows that DII is a good tool for assessing the overall inflammatory potential of diet in HD patients.
