Industrial processing of condiments and seasonings and its implications for micronutrient fortification

The Potential of Condiments, Seasonings, and Bouillon Cubes to Deliver Essential Micronutrients in Asia: Scenario Analyses of Iodine and Iron Fortification

Micronutrient deficiencies are still highly prevalent in Asia. Fortification of cooking aids, such as condiments (fish and soy sauces), seasonings, and bouillon cubes, may be an additional strategy to improve micronutrient intake. The current study evaluated the potential impact of iodine and iron fortification of cooking aids on micronutrient intake in Asian countries. A systematic literature search was performed to collect consumption data from different countries in Asia. Data from 18 studies in nine Asian countries were included. Scenario analyses were performed using different fortification levels based on regulations and literature. Mean intake of cooking aids ranged from 3.2-15.9 g/day for condiments and 0.4-11.7 g/day for seasonings and bouillon cubes. When replacing salt with iodized salt (30 µg of iodine/g of salt), iodine intake would increase by 13-119 µg/day for soy and fish sauces (9-80% of the Nutrient Reference Value (NRV)), and 5-83 µg/day for bouillon cubes and seasonings (4-56% of the NRV). Fortification with iron 0.5 mg/g food product for condiments or 1 mg/g food product for bouillon cubes and seasonings improved iron intake for soy and fish sauces by 1.6-8.0 mg/day (11-57% of the NRV), and for bouillon cubes and seasonings by 0.4-5.6 mg/day (3-40% of the NRV). These results indicate that, depending on the consumption pattern, fortification of cooking aids can be a suitable strategy to increase intake of micronutrients.

Hutton Z, Fattore G, Sabatier M, Detzel P. Reducing the burden of iron deficiency anemia in Cote D'Ivoire through fortification

BACKGROUND

Iron deficiency anemia (IDA) is highly prevalent in the Cote d'Ivoire and has severe health and economic consequences. In this paper, we apply a health economic model to quantify the burden of IDA, and the contribution of nationwide mandatory iron fortification of wheat flour and voluntary iron fortification of condiments to the reduction of this burden.

METHODS

The analysis for the population from 6 months to 64 years builds on published reviews and publicly available datasets and is stratified by age-groups and socioeconomic strata using comparative risk assessment model.

RESULTS

Without the impact of these fortification strategies, the annual burden of IDA is estimated at 242,100 disability adjusted life years (DALYs) and 978.1 million USD. Wheat flour and condiment fortification contributed to a reduction of the IDA burden by approximately 5% each.

CONCLUSION

In places with high prevalence of malaria and other infectious diseases, such as the Côte D'Ivoire, food fortification as a nutritional intervention should be accompanied with infectious disease prevention and control. The findings of this study provide additional input for policy makers about the magnitude of the impact and can support the conception of future fortification strategies.

Performance Factors Influencing Efficacy and Effectiveness of Iron Fortification Programs of Condiments for Improving Anemia Prevalence and Iron Status in Populations: A Systematic Review

Iron fortification of staple foods is a common practice around the world to reduce the prevalence of iron-deficiency anemia. More recently, fortified condiments, including salts, sauces, and powders, have been tested in various efficacy trials. However, there is limited information on how nutritional, environmental, and experimental factors affect their efficacy and effectiveness. The purpose of the present work was to systematically review performance factors affecting the efficacy of condiment fortification trials. Three databases were searched using a standardized keyword search and included based on four-point inclusion criteria. Studies were evaluated against a quality assessment tool and effect sizes were calculated. Studies were ranked as low or high performing, based on whether or not they significantly improved iron-deficiency outcomes (hemoglobin, anemia prevalence, and ferritin levels). Of the 955 retrieved studies, 23 were included-of which, nine performed poorly, eight performed highly, and six were classified as neither because they did not meet the criteria of assessing the three iron outcomes. Results showed that unsuccessful trials did not consider environmental factors such as parasitic infections, nutritional factors such as micronutrient deficiencies other than iron, consumer acceptability of the product or experimental factors such as monitoring and adherence to the trials. Two common performing factors identified among those studies performing highly vs. those that did not were the control of sensory changes and monitoring of consumption compliance (i.e., dose delivery). The present work can be used as decision-making support for nutrition policy makers when determining the appropriate implementation of condiment fortification programs.

Public Health Aspects in the Prevention and Control of Vitamin Deficiencies

Vitamin deficiencies remain major etiological factors in the global burden of disease, especially in low- and middle-income countries. The purpose of this state-of-the-art review was to update current information on deficiencies of vitamins and public health approaches to addressing them. Some stages of life present a higher risk of deficiency than others: risks are higher in pregnant women, children (from conception to young childhood), adolescents, the elderly, and all of the over 800 million people globally who are undernourished. At risk are approximately 125 million preschool children with vitamin A deficiency, as well as sub-populations at risk of deficiencies of folate, thiamin, vitamin B12, niacin, riboflavin, other B vitamins. and vitamin D. Addressing micronutrient deficiencies requires identifying those at risk and then working to prevent and manage that risk. Public health approaches include improved, diversified diets; supplementation; fortification and biofortification; and other supportive public health measures. Historically, as with pellagra and beriberi and, in the last 3 decades, with vitamin A and folic acid, there has been encouraging progress, but much remains to be done.

More than two-thirds of dietary iodine in children in northern Ghana is obtained from bouillon cubes containing iodized salt

OBJECTIVE

Bouillon cubes are widely consumed by poor households in sub-Saharan Africa. Because their main ingredient is salt, bouillon cubes could be a good source of iodine if iodized salt is used in their production and if their consumption by target groups is high. Our objective was to measure the iodine content of bouillon cubes, estimate their daily intake in school-aged children and evaluate their potential contribution to iodine intakes.

DESIGN

In a cross-sectional study, we measured urinary iodine concentrations (UIC) and estimated total daily iodine intakes. We administered a questionnaire on usage of bouillon cubes. We measured the iodine content of bouillon cubes, household salt, drinking-water and milk products.

SETTING

Primary schools in northern Ghana.

SUBJECTS

Schoolchildren aged 6-13 years.

RESULTS

Among school-aged children (n 250), median (interquartile range) UIC and estimated iodine intake were 242 (163-365) µg/l and 129 (85-221) µg/d, indicating adequate iodine status. Median household salt iodine concentration (n 100) was only 2·0 (0·83-7·4) µg/g; 72 % of samples contained <5 µg iodine/g. Iodine concentrations in drinking-water and milk-based drinks were negligible. Median iodine content of bouillon cubes was 31·8 (26·8-43·7) µg/g, with large differences between brands. Estimated median per capita consumption of bouillon cubes was 2·4 (1·5-3·3) g/d and median iodine intake from bouillon cubes was 88 (51-110) µg/d.

CONCLUSIONS

Despite low household coverage with iodized salt, iodine nutrition in school-aged children is adequate and an estimated two-thirds of their dietary iodine is obtained from bouillon cubes.

Estimating nutrient fortification levels in condiments and seasonings for public health programs: considerations and adaptations

Condiments and seasonings have been considered as potential vehicles for fortification in place of, or in addition to, fortifiable staple foods. Methodologies for establishing fortification programs focus primarily on use of staple foods, which are consumed in larger portions than condiments and seasonings. Some fortification models assume self-limiting consumption relative to the maximum energy consumed by target populations. However, this assumption may prove incorrect for estimating fortification concentrations of condiments and seasonings because they may only provide negligible energy. Although flavor or color may limit consumption, these limits would vary across each condiment or seasoning vehicle. In addition, the small volume of condiments and seasonings consumed relative to staple foods can lead to proportionally larger potential errors than with staple foods when measuring usual dietary intakes for establishing safe and effective fortification concentrations. This paper reviews available methods for setting fortification levels, whether or how available methods or conceptual frameworks could be adapted to condiments and seasonings, and gaps in knowledge for appropriately using condiments and seasonings as vehicles for fortification in public health.

Large-scale fortification of condiments and seasonings as a public health strategy: equity considerations for implementation

Fortification of staple foods with vitamins and minerals is an effective approach to increase micronutrient intake and improve nutritional status. The specific use of condiments and seasonings as vehicles in large-scale fortification programs is a relatively new public health strategy. This paper underscores equity considerations for the implementation of large-scale fortification of condiments and seasonings as a public health strategy by examining nonexhaustive examples of programmatic experiences and pilot projects in various settings. An overview of conceptual elements in implementation research and equity is presented, followed by an examination of equity considerations for five implementation strategies: (1) enhancing the capabilities of the public sector, (2) improving the performance of implementing agencies, (3) strengthening the capabilities and performance of frontline workers, (3) empowering communities and individuals, and (4) supporting multiple stakeholders engaged in improving health. Finally, specific considerations related to intersectoral action are considered. Large-scale fortification of condiments and seasonings cannot be a standalone strategy and needs to be implemented with concurrent and coordinated public health strategies, which should be informed by a health equity lens.
