Nutritional Considerations of Vitamin D Deficiency and Strategies of Food Fortification

Abstract

Vitamins and minerals are crucial for human health. Any deficiency can lead to major diseases; however, the most prevalent one is the vitamin D deficiency. Due to its high risk in the Middle East and Lebanon, besides its major effects, solutions to decrease this deficiency are taken nowadays. Vitamin D food fortification is the most popular solution taken now. Liposomes showed highest efficiency in vitamin D fortification. However, a study must be done in order to deduce the amounts needed in the targeted population. Therefore, before fortification starts, FDA regulations must be reviewed. Several foods succeeded in fortification with vitamin D and increasing its levels such as milk and cheddar cheese. Stability and flavors showed good results over fortification, while according to the odor, water sources showed more aroma depth than oil sources. The AOAC methods for vitamin D amount in fortified foods must be applied. Dietary 25(OH)D3 was 7.14-fold more effective at raising serum 25(OH)D than dietary vitamin D3.
