The Potential Contribution of Fortified Maize Flour, Oil, Rice, Salt, and Wheat Flour to Estimated Average Requirements and Tolerable Upper Intake Levels for 15 Nutrients in 153 Countries.

ABSTRACT: Food fortification is designed to improve the nutritional profile of diets. The purpose of this research was to estimate the potential nutrient contribution of fortified maize flour, oil, rice, salt, and wheat flour in 153 countries, using the national intake (or availability) of the food and the nutrient levels required for fortification. This was done under two scenarios-maximum, where 100% of the food is assumed to be industrially processed and fortified, and realistic, where the maximum value is adjusted based on the percent of the food that is industrially processed and fortified. Under the maximum scenario, the median Estimated Average Requirements (EARs) met ranged from 22-75% for 14 nutrients (vitamins A, B1, B2, B3, B6, B12, D, E, folic acid and calcium, fluoride, iron, selenium and zinc), and 338% for iodine. In the realistic scenario, the median EARs met were 181% for iodine and <35% for the other nutrients. In both scenarios, the median Tolerable Upper Intake Levels (ULs) met were <55% for all nutrients. Under the realistic scenario, no country exceeded 100% of the UL for any nutrient. Current fortification practices of the five foods of interest have the global potential to contribute up to 15 nutrients to the diets of people, with minimal risk of exceeding ULs.

Project description:Following a request from the European Commission (EC), the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on the revision of the tolerable upper intake level (UL) for folic acid/folate. Systematic reviews of the literature were conducted to assess evidence on priority adverse health effects of excess intake of folate (including folic acid and the other authorised forms, (6S)-5-methyltetrahydrofolic acid glucosamine and l-5-methyltetrahydrofolic acid calcium salts), namely risk of cobalamin-dependent neuropathy, cognitive decline among people with low cobalamin status, and colorectal cancer and prostate cancer. The evidence is insufficient to conclude on a positive and causal relationship between the dietary intake of folate and impaired cognitive function, risk of colorectal and prostate cancer. The risk of progression of neurological symptoms in cobalamin-deficient patients is considered as the critical effect to establish an UL for folic acid. No new evidence has been published that could improve the characterisation of the dose-response between folic acid intake and resolution of megaloblastic anaemia in cobalamin-deficient individuals. The ULs for folic acid previously established by the Scientific Committee on Food are retained for all population groups, i.e. 1000 μg/day for adults, including pregnant and lactating women, 200 μg/day for children aged 1-3 years, 300 μg/day for 4-6 years, 400 μg/day for 7-10 years, 600 μg/day for 11-14 years and 800 μg/day for 15-17 years. A UL of 200 μg/day is established for infants aged 4-11 months. The ULs apply to the combined intake of folic acid, (6S)-5-methyltetrahydrofolic acid glucosamine and l-5-methyltetrahydrofolic acid calcium salts, under their authorised conditions of use. It is unlikely that the ULs for supplemental folate are exceeded in European populations, except for regular users of food supplements containing high doses of folic acid/5-methyl-tetrahydrofolic acid salts.
