RESUMO

Although mandatory fortification of oil with vitamin A is efficacious, its effectiveness can be compromised by suboptimal compliance to standards. In this study, we assessed (1) the availability of oil brands across the eight divisions of Bangladesh, (2) fortification quality (the extent to which vitamin A content is aligned with fortification standards) of oil brands and producers and (3) the market volume represented by available edible oil types. We visited different retail outlets in rural and urban market hubs to ascertain available oil brands and bulk oil types and collected samples. We used high-performance liquid chromatography to quantify average vitamin A content and compared them to the national oil fortification standards. Among the 66 packaged brands analyzed, 26 (39%) were not fortified, and 40 (61%) were fortified, with 28 (42%) fortified above the standard vitamin A minimum. Among the 41 bulk oil type composites analyzed, 24 (59%) were not fortified, and 17 (41%) were fortified, with 14 (34%) fortified below and 3 (7%) fortified above the standard minimum. Vitamin A fortification is high for packaged and branded edible oil but low for oil sold in unbranded, loose form. As bulk oil makes up a large proportion of the oil market volume, this means the majority of the oil volume available to the population is either not (25%) or fortified below the standard requirement (39%). Regulatory inspections of producers selling bulk oil should be prioritized to support and incentivize the industry to make all oil traceable and fortified to standard.

RESUMO

Low dietary calcium is very common in many populations, contributing to nutritional rickets/osteomalacia in children/adults and increasing the risk of several health problems. Calcium is a nutrient of concern as the recommended nutrient requirements are difficult to meet in the absence of dairy products. The provision of culturally acceptable calcium-fortified foods may improve calcium intake when it is a feasible and cost-effective strategy in a particular setting. This landscape review was conducted in 2019 and describes current calcium fortification efforts and lessons learned from these experiences. Worldwide, the United Kingdom is the only country where calcium fortification of wheat flour is mandatory. It is estimated that this fortified staple ingredient contributes to 13-14% of calcium intake of the British population. Other items voluntary fortified with calcium include maize flour, rice, and water. Current calcium fortification programs may lack qualified personnel/training, clear guidelines on implementation, regulation, monitoring/evaluation, and functional indicators. Also, the cost of calcium premix is high and the target groups may be hard to reach. There is a lack of rigorous evaluation, particularly in settings with multiple micronutrient programs implemented simultaneously, with low quality of the evidence. Further research is needed to assess the impact of calcium fortification programs.

RESUMO

Large-scale food fortification is an effective, sustainable, and scalable intervention to address vitamin and mineral deficiencies, however, pressing gaps exist globally around ensuring the quality of fortified foods. This paper summarizes the global challenges and gaps faced in monitoring the quality of fortified foods, the guidance produced in response to these challenges, where we are today in terms of effective implementation, and what approaches and opportunities may be usefully applied to enhance the quality of fortified foods moving forward.

RESUMO

BACKGROUND: There is an opportunity to reduce child mortality by preventing folic acid-preventable spina bifida and anencephaly (FAP SBA) in developing countries. We estimated reductions in FAP SBA-associated child mortality in 69 countries with an immediate potential for mandatory fortification of wheat flour. METHODS: Using data from multiple sources, we estimated the percent reductions in neonatal, infant, and under-five mortality that would have occurred by preventing FAP SBA; and the contributions of these reductions toward each country's Sustainable Development Goals (SDG) for child mortality reduction. We used the combined prevalence of spina bifida and anencephaly in selected countries before fortification, and estimated preventable child mortality associated with FAP SBA, assuming 0.5 per 1,000 live births as minimum achievable prevalence from mandatory fortification. RESULTS: Annually, 56,785 live births with FAP SBA occurred in the 69 countries examined. Of these, about 49,680 (87%) would have resulted in deaths under age 5 years, and are preventable through mandatory folic acid fortification. On average, compared to current rates, prevention of FAP SBA would have reduced the neonatal, infant, and under-five mortality by 19% (95% uncertainty interval [UI]: 16-24%), 15% (UI: 13-17%), and 14%, (95% UI: 13-17%), respectively. Prevention of FAP SBA seemed to contribute toward achieving SDG on neonatal and under-five mortality in developing countries. CONCLUSIONS: Prevention of FAP SBA will lead to notable and immediate reductions in child mortality. Many countries have an opportunity to effectively move toward child mortality-related SDG targets with existing milling infrastructure for food fortification.

RESUMO

PURPOSE: To assess iodine and fluoride status among Lebanese children. METHODS: A nationally representative cross-sectional study of 6- to 10-year-old schoolchildren was conducted using multistage cluster sampling. Spot urine samples were collected from 1403 children, and urinary iodine, fluoride, creatinine and sodium levels were measured. Salt samples from markets (n = 30) were tested for iodine concentration by titration. RESULTS: Median urinary iodine concentration was 66.0 µg/l, indicating mild deficiency, and almost 75 % of Lebanese children had a urinary iodine concentration (UIC) <100 µg/l. UIC was higher among children from private schools and in areas of higher socioeconomic status. Most salt samples were fortified at levels far below the legislated requirement, and 56 % of samples contained less than 15 ppm iodine. Fluoride-to-creatinine ratio (F/Cr) was 0.250 (0.159-0.448) mg/g. There were weak positive correlations between UIC and urinary sodium (r 2 = 0.039, P value <0.001) and UIC and urinary fluoride (r 2 = 0.009, P value <0.001). CONCLUSIONS: Lebanese elementary school children are iodine deficient due to inadequately iodized salt. The weak correlation between UIC and urinary sodium suggests most dietary iodine does not come from iodized salt. The poor correlation between UIC and urinary fluoride suggests that fluoride intake is not affecting iodine metabolism. Efforts are needed in Lebanon to improve industry compliance with salt fortification through improved monitoring and enforcement of legislation.

RESUMO

INTRODUCTION: Although fortification of food with folic acid has been calculated to be cost saving in the U.S., updated estimates are needed. This analysis calculates new estimates from the societal perspective of net cost savings per year associated with mandatory folic acid fortification of enriched cereal grain products in the U.S. that was implemented during 1997-1998. METHODS: Estimates of annual numbers of live-born spina bifida cases in 1995-1996 relative to 1999-2011 based on birth defects surveillance data were combined during 2015 with published estimates of the present value of lifetime direct costs updated in 2014 U.S. dollars for a live-born infant with spina bifida to estimate avoided direct costs and net cost savings. RESULTS: The fortification mandate is estimated to have reduced the annual number of U.S. live-born spina bifida cases by 767, with a lower-bound estimate of 614. The present value of mean direct lifetime cost per infant with spina bifida is estimated to be $791,900, or $577,000 excluding caregiving costs. Using a best estimate of numbers of avoided live-born spina bifida cases, fortification is estimated to reduce the present value of total direct costs for each year's birth cohort by $603 million more than the cost of fortification. A lower-bound estimate of cost savings using conservative assumptions, including the upper-bound estimate of fortification cost, is $299 million. CONCLUSIONS: The estimates of cost savings are larger than previously reported, even using conservative assumptions. The analysis can also inform assessments of folic acid fortification in other countries.

RESUMO

Micronutrient deficiencies remain a significant public health issue in Southeast Asia, particularly in vulnerable populations, such as women of reproductive age and young children. An important nutrition-specific intervention to address micronutrient malnutrition is fortification of staple foods and condiments. In October 2013, the International Life Sciences Institute (ILSI) Southeast Asia Region held a workshop on micronutrient fortification of food in Bangkok, Thailand. The objective was to engage multiple stakeholders in a discussion on food fortification and its importance as a public health intervention in Southeast Asia, and to identify and address key challenges/gaps in and potential opportunities for fortification of foods in ASEAN countries. Key challenges that were identified include: "scaling up" and mobilizing sustainable support for fortification programs in the form of multi-stakeholder partnerships, effecting policy change to support mandatory fortification, long-term monitoring of the programs' compliance and efficacy in light of limited resources, and increasing awareness and uptake of fortified products through social marketing campaigns. Future actions recommended include the development of terms of engagement and governance for multi-stakeholder partnerships, moving towards a sustainable business model and more extensive monitoring, both for effectiveness and efficacy and for enforcement of fortification legislation.

RESUMO

BACKGROUND: Linear programming has been used for analyzing children's complementary feeding diets, for optimizing nutrient adequacy of dietary recommendations for a population, and for estimating the economic value of fortified foods. OBJECTIVE: To describe and apply a linear programming tool ("Cost of the Diet") with data from Mozambique to determine what could be cost-effective fortification strategies. METHODS: Based on locally assessed average household dietary needs, seasonal market prices of available food products, and food composition data, the tool estimates the lowest-cost diet that meets almost all nutrient needs. The results were compared with expenditure data from Mozambique to establish the affordability of this diet by quintiles of the population. RESULTS: Three different applications were illustrated: identifying likely "limiting nutrients," comparing cost effectiveness of different fortification interventions at the household level, and assessing economic access to nutritious foods. The analysis identified iron, vitamin B2, and pantothenic acid as "limiting nutrients." Under the Mozambique conditions, vegetable oil was estimated as a more cost-efficient vehicle for vitamin A fortification than sugar; maize flour may also be an effective vehicle to provide other constraining micronutrients. Multiple micronutrient fortification of maize flour could reduce the cost of the "lowest-cost nutritious diet" by 18%, but even this diet can be afforded by only 20% of the Mozambican population. CONCLUSIONS: Within the context of fortification, linear programming can be a useful tool for identifying likely nutrient inadequacies, for comparing fortification options in terms of cost effectiveness, and for illustrating the potential benefit of fortification for improving household access to a nutritious diet.

RESUMO

OBJECTIVE: To study the highest levels for vitamin A voluntary fortification in food by using the principles and methods of risk assessment. METHODS: The dietary nutrient intake data of 68 962 subjects form "Survey on the Status of Nutrition and Health of the Chinese People" in 2002 were analyzed to calculate the highest fortification level of vitamin A in different groups stratified by age, sex and economic development level, using maximum sage fortification level (MSFL) model recommended by European countries. The results were compared with the current national standards of China. RESULTS: The overall results showed that women aged ≥5 0 years had the highest MSFL(2011.5 µgRE/1000 KJ) and the men aged 14 - 17 years had the lowest MSFL (1078.5 µgRE/1000 KJ). The MSFL for pregnant women was 1066.8 µgRE/1000 KJ. The results in different areas showed that men and women aged 14 - 17 years in large city had lower MFSL(997.3 and 879.1 µgRE/1000 KJ respectively). the MSFL in other groups in different areas were between 1000 - 2000 µgRE/1000 KJ. After conversion using the lowest MSFL, the highest fortification levels for vegetable oil, wheat flour, rice, modified milk, biscuit, soybean powder, milk powder for preschool children, milk powder for pregnant and lactating women were 33 063,12 650,12 729,1978,15 929,15 411,20 642,17 920 µgRE/kg respectively,higher than the current fortified level in national standard. CONCLUSION: The current fortification levels in foods are safe and the risk of over intake of vitamin A from fortified food is very low.

RESUMO

Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) are almost unanimously recognized for their health benefits, while only limited evidence of any health benefit is currently available specifically for the main precursor of these fatty acids, namely α-linolenic acid (ALA, 18:3n-3). However, both the n-3 LC-PUFA and the short-chain C18 PUFA (i.e., ALA) are commonly referred to as "omega-3" fatty acids, and it is difficult for consumers to recognize this difference. A current gap of many food labelling legislations worldwide allow products containing only ALA and without n-3 LC-PUFA to be marketed as "omega-3 source" and this misleading information can negatively impact the ability of consumers to choose more healthy diets. Within the context of the documented nutritional and health promoting roles of omega-3 fatty acids, we briefly review the different metabolic fates of dietary ALA and n-3 LC-PUFA. We also review food sources rich in n-3 LC-PUFA, some characteristics of LC-PUFA and current industry and regulatory trends. A further objective is to present a case for regulatory bodies to clearly distinguish food products containing only ALA from foods containing n-3 LC-PUFA. Such information, when available, would then avoid misleading information and empower consumers to make a more informed choice in their food purchasing behavior.

RESUMO

BACKGROUND: In sub-Saharan Africa, more than 42% of children are at risk for vitamin A deficiency, and control of vitamin A deficiency will prevent more than 600,000 child deaths annually. In the West African Economic and Monetary Union (UEMOA), an estimated 54.3% of preschool-age children are vitamin A deficient and 13% of pregnant women have night blindness. OBJECTIVE: To project the achievements of this West African coalition. METHODS: This article documents the achievements, challenges, and lessons learned associated with the development of a public-private partnership to fortify vegetable oil in West Africa through project reports and industry assessments. RESULTS: National-level food consumption surveys identified cooking oil as a key vehicle for vitamin A. Stakeholders therefore advocated for the production of fortified vegetable oil at large scale, supported industrial assessments, and reinforced the capacity of cooking oil industries to implement vitamin A fortification through effective coordination of public and private partnerships tied with standards, regulations, and social marketing. Strong alliances for food fortification were established at the regional and national levels. Stakeholders also developed policies, adopted directives, built capacity, implemented social marketing, and monitored quality enforcement systems to sustain fortification for maximum public health impact. The synergy created resulted from the unique and complementary core competencies of all the partners under effective coordination. The initiative began with the 8 UEMOA member countries and now includes all 15 countries of the Economic Community of West African States (ECOWAS), plus Cameroon, Tanzania, and Mozambique, forming a sub-Saharan Africa-wide initiative on food fortification. All members of the Professional Association of Cooking Oil Industries of the West African Economic and Monetary Union (AIFO-UEMOA) now fortify edible oil with vitamin A. Through multisector cooperation, an estimated 70% of the population has access to vitamin A-fortified edible oil in participating countries. CONCLUSIONS: Sustainable fortification of cooking oil is now a reality in all UEMOA countries.

RESUMO

BACKGROUND: Wheat and maize flours are widely used delivery vehicles for mass fortification. In lower-income countries, most, if not all, national-level cereal flour fortification programs routinely fortify with iron; however, cofortification with other micronutrients is common. Little information is available on the cost implications programs face when considering current fortification practices versus what the World Health Organization (WHO) interim consensus statement recommends. OBJECTIVE: The objectives of the present paper are to provide information on the costs of adding different chemical forms of iron and/or other micronutrients to premix formulations, and to discuss some of the issues that should be considered regarding which micronutrients to include in the premix. METHODS: Nine countries in Latin America, Africa, and Asia (three countries per region) that currently cofortify with multiple micronutrients including iron were selected based on low (< 75 g/day), medium (75 to 149 g/day), and high (> or = 150 g/day) mean population flour consumption levels. Premix costs per metric ton of flour produced were estimated for improving iron formulations and for following WHO recommendations for other micronutrients. RESULTS: For the selected programs to maintain current premix formulations and improve iron compounds, premix costs would increase by between 155% and 343% when the iron compound was switched from electrolytic iron to sodium iron ethylenediaminetetraacetate (NaFeEDTA), by 6% to 50% when it was switched from electrolytic iron to ferrous sulfate, and by 4% to 13 when iron addition rates were adjusted without switching the compound. To meet WHO recommendations for other micronutrients, premix costs would increase the most when the amounts of vitamins B12 and A were increased. CONCLUSIONS: For programs that currently cofortify with iron and additional micronutrients, the quality of the iron fortificant should not be overlooked simply to be able to afford to add more micronutrients to the premix. Micronutrients should be selected according to population needs, costs, and potential beneficial synergistic reactions the added micronutrients may have.

RESUMO

BACKGROUND: Micronutrient deficiencies affect over 2 billion people worldwide, with profound implications for health, cognitive development, education, economic development, and productivity. Fortification of staple foods is a cost-effective strategy to increase vitamin and mineral intake among the general population. Rice is consumed by billions of people (> 440 million MT/year) but is as yet rarely fortified. OBJECTIVE: To discuss the untapped opportunity of rice fortification. METHODS: Review literature and experience with rice fortification and compare to fortification of other staple foods. RESULTS: Most technologies used to fortify rice first produce the fortified kernels and then blend them with regular, polished rice. Technologies differ with regard to how nutrients are added to the rice kernels, required investment, production cost, and degree of resemblance to unfortified rice. There are, so far, limited success stories for rice fortification. Some of the main roadblocks appear to be high initial investment and associated cost; lack of government leadership; and consumer hesitation to accept variations in the characteristics of rice, or a higher price, without good understanding of the benefits. CONCLUSIONS: In countries with a large centralized rice milling industry, starting rice fortification is easier than in countries with many small mills. Countries with large safety nets that supply rice to the poorest, for free or subsidized, have a good channel to reach those most in need. Furthermore, key players from the public and private sectors should establish a coalition to support the use of fortified rice and address some of the barriers to its implementation.

RESUMO

BACKGROUND: Vitamin and mineral premix is one of the most significant recurring input costs for large-scale food fortification programs. A number of barriers exist to procuring adequate quality premix, including accessing suppliers, volatile prices for premix, lack of quality assurance and monitoring of delivered products, and lack of funds to purchase premix. OBJECTIVE: To develop and test a model to procure premix through a transparent and efficient process in which an adequate level of quality is guaranteed and a financial mechanism is in place to support countries or specific target groups when there are insufficient resources to cover the cost of premix. METHODS: Efforts focused on premixes used to fortify flour, such as wheat or maize (iron, zinc, B vitamins, and vitamin A), edible oils (vitamins A and D), and other food vehicles, such as fortified complementary foods, complementary food supplements, and condiments. A premix procurement model was set up with three distinct components: a certification process that establishes industry-wide standards and guidelines for premix, a procurement facility that makes premix more accessible to countries and private industry engaged in fortification, and a credit facility mechanism that helps projects finance premix purchases. RESULTS: After three years of operation, 15 premix suppliers and 29 micronutrient manufacturers have been certified, and more than US$23 million worth of premix that met quality standards has been supplied in 34 countries in Africa, Central and Southern Asia, and Eastern Europe, reaching an estimated 242 million consumers. CONCLUSIONS: The Premix Facility demonstrated its effectiveness in ensuring access to high-quality premixes, therefore enabling the success of various fortification programs.

RESUMO

The concept of functional foods was born in Japan in the 1980s. They are foods that were developed specifically to promote health or reduce the risk of disease. Functional foods have not already been defined by the legislation in Europe. Generally, they are considered as those foods which are intended to be consumed as part of the normal diet and which contain biologically active components which offer the potential of enhanced health or reduced risk of disease. Attention concerning this category of foods has grown, new products have appeared in the European market and interest has turned to define the standards and guidelines for the development and promotion of this kind of foods. In the European Union, there is harmonised legislation on health claims, while compounds, ingredients, plants are still regulated only at national level. The question of traditional use and the role of European Food Safety Authority as European Authority for Food Safety will be examined.

RESUMO

INTRODUCTION: Lysine fortification of wheat flour has been used toward reducing protein energy malnutrition in developing countries. METHODS: The feasibility of fortifying instant noodles with lysine was evaluated based on sensory qualities and the residual lysine content. Fifty grams of deep-fried and dried instant noodles were fortified with 0.23 and 0.21 g lysine, respectively. The production temperatures used for deep-frying were 165-175 degrees C and for drying, 80-105 degrees C; these are the temperatures used in the industrial production of both kinds of noodles. Lysine fortification was then performed at the local factories using the commercial production lines and packaging for both types of instant noodles. Both fortified and unfortified deep-fried and dried instant noodles were stored at 50 degrees C under fluorescent light for 2 and 4 months, respectively. RESULTS: The fortified products were tested for residual lysine content and sensory qualities as compared with unfortified noodles. The results show fortified products from the tested processing temperatures were all accepted. After storage, significant losses of lysine were not found in both types of noodles analysed. The lysine-fortified noodles had amino acid scores of 102% and 122%, respectively. After 2 months, the sensory quality of fortified deep-fried noodles was still acceptable; however, the dried noodles turned to an unacceptable dark colour. CONCLUSION: This study shows that it is feasible to fortify deep-fried instant noodles with lysine, though lysine fortification exhibited an undesirable colour in the dried instant noodles after storage.

RESUMO

Different European institutions have developed mathematical models to propose maximum safe levels either for fortified foods or for dietary supplements. The objective of the present study was to compare and check the safety of these different maximum safe levels (MSL) by using a probabilistic risk assessment approach. The potential maximum nutritional intakes were estimated by taking into account all sources of intakes (base diet, fortified foods and dietary supplements) and compared with the tolerable upper intake levels for vitamins and minerals. This approach simulated the consequences of both food fortification and supplementation in terms of food safety. Different scenarios were tested. They are the result of the combination of several MSL obtained using the previous models. The study was based on the second French Individual and National Study on Food Consumption performed in 2006-7, matched with the French food nutritional composition database. The analyses were based on a sample of 1918 adults aged 18-79 years. Some MSL in fortified foods and dietary supplements obtained independently were protective enough, although some others could lead to nutritional intakes above the tolerable upper intake levels. The simulation showed that it is crucial to consider the inter-individual variability of fortified food intakes when setting MSL for foods and supplements. The risk assessment approach developed here by integrating the MSL for fortified foods and dietary supplements is useful for ensuring consumer protection. It may be subsequently used to test any other MSL for vitamins and minerals proposed in the future.

RESUMO

BACKGROUND: Vitamin A deficiency is a major public health nutrition problem, affecting an estimated 190 million preschool-aged children and 19 million pregnant and lactating women globally, and 83 million adolescents in Southeast Asia alone. Its consequences (disorders) include xerophthalmia (the leading cause of early childhood blindness), increased severity of infection, anemia, and death. Because vitamin A deficiency is largely due to chronic dietary insufficiency of preformed vitamin A and proactive carotenoids, food fortification can offer an effective approach to prevention. OBJECTIVE: To provide guidance on fortifying wheat and maize flour milled in industrial rollers for national fortification programs in countries where vitamin A deficiency is considered a public health problem. METHODS: Critical review of the literature on the dietary gap in vitamin A intake and levels of wheat flour intake among risk groups as a basis for determining vitamin A fortificant levels. Additional review of efficacy evidence, safety and cost considerations, and country experiences related to wheat-flour fortification with vitamin A. RESULTS: Mill-rolled wheat flour is a technically fortifiable, centrally processed food vehicle that, where routinely and adequately consumed by target groups, should be considered a candidate for fortification. Vitamin A can be stable in flour under typical, ambient conditions, with processing losses estimated at approximately 30%, depending on source and premix conditions. CONCLUSIONS: Factors to guide a decision to fortify flour with vitamin A include the extent of deficiency, availability of other food vehicle options, the centrality of milling, market reach and population intake distributions of the flour products, the dietary vitamin A intake required, and associated costs. Large gaps persist in knowledge of these factors, which are needed to enable evidence-based fortification in most countries, leaving most decisions to fortify guided by assumptions. Where flour can and should be fortified, guidelines are given for providing nearly 25% of the Recommended Dietary Allowance for vitamin A to vulnerable groups consuming varying ranges of flour products. The costs will vary according to the level of fortification.

RESUMO

A promising approach to improving health care would be to produce a healthier food supply as a preventive health care strategy. The food supply could be improved by producing functional foods that have nutritional profiles that are healthier than conventional products. However, production of functional foods is not always easily accomplished since they must also taste good, be convenient and reasonably priced so that consumers will regularly purchase and use the products. Meats have great potential for delivering important nutrients such as fatty acids, minerals, dietary fiber, antioxidants and bioactive peptides into the diet. However, to produce successful products with these ingredients, technologies must be developed to increase their stability and decrease their flavor impact on muscle foods. In addition, many regulatory hurdles must be overcome for the commercial production of meats with added nutrients. These include redefinition of standard of identities and policies that allow front of the package nutritional claims. Without these regulatory changes, production of healthier meat products won't become a reality since these products would not have a competitive advantage over unfortified meats.
