Vitamin A (also called retinol) is a fat-soluble nutrient essential for the maintenance of our body. It is also an important nutrient because it cannot be produced by our body and must be provided as part of our diet. Vitamin A helps the body to grow well and strengthens immune system to resist diseases. It also promotes the development of certain organs in the body, especially the eye. While we can get Vitamin A from plant foods like carrot, pumpkin, and human milk, this nutrient is also available in animal foods, including dairy products (whole milk, yoghurt, cheese), liver, and fish oils.
Recently, the World Health Organization proposed that vitamin A deficiency has affected some groups of people, such as young children, women of childbearing age and pregnant women. Vitamin A deficiency has multiple consequences that affect our health and bodily functions. Today, Vitamin Deficiency Disease (VAD) remains a worldwidemain factor. Young children and pregnant women need to eat more foods rich in vitamin A to avoid the occurrence of deficiency.
