Abstract

Numerous studies examining the status of vitamin D in the diet in many countries around the world have shown that in terms of nutrition, most countries do not have a favorable situation in this area. One of the important biological functions of vitamin D is to control the absorption, transport, and deposition of calcium, and to lesser extent phosphorus, in the process of bone mineralization. Vitamin D is an essential fat-soluble vitamin that plays important role in skeletal and non-skeletal organs, including the prevention of chronic diseases such as diabetes, cardiovascular disease, autoimmune disorders, and cancer. One way to get this vitamin is to take it through food, while only a limited number of foods naturally contain high amounts of vitamin D, so a deficiency of this vitamin has always been reported and the enrichment of food consumed by humans from it is a common method used to overcome such deficiencies in food micronutrients. Dairy products, especially milk, are an ideal choice for fortification with vitamin D, calcium, and sometimes other minerals.
