Health is wealth in human life. Health depends on the daily need of body nutrients and its supply accordingly. Among all the nutrients, although vitamins are required in very small quantities but they play very important role in the body. Among all the vitamins, one of the most important vitamin for human health is vitamin A. Chemically it is named as retinol and found in foods of animal origin only. Its richest source is fish liver oil. Butter, cheese and egg yolk are good source. Carotenoids found in the plants are metabolised in our intestine giving rise vit A. It is very important for vision, healthy skin, growth and bone development, health and reproduction. Many diseases including night blindness may occur because of its deficieny. Hence, our diet should include vit A or carotenoids.
