VITAMIN A
Vitamin A is a fat-soluble vitamin that has many different functions. First, it is related to the maintenance of normal vision in dim light and the prevention of night blindness. It also helps in the growth and formation of body cells, making it essential for body growth. It is especially needed for bone growth. If the intake is not sufficient, bones will stop growing before the soft tissues are fully mature. Vitamin A is also needed for normal tooth development, because the enamel-forming cells are affected by a lack of vitamin A. Like the carotenoids, vitamin A is also important for the maintenance of healthy epithelial cells. There are two kinds of epithelial tissue: those that cover the outer surfaces of the body - the resistant, protective skin (epidermis) and those that line all the mucus membranes. Without vitamin A, the epithelial cells become dry and flat and gradually harden to form scales that shed. Vitamin A is also important to the health of the membranes lining the stomach, intestinal wall, bladder and urinary tract and for the health of the sex glands and uterus. Lastly, vitamin A works better where there are sufficient levels of zinc and adequate protein intake in the diet.
Good sources of vitamin A include: cheese,eggs,oily fish,fortified low-fat spreads,milk and yoghurt.Liver is a particularly rich source of vitamin A, although this means you may be at risk of having too much vitamin A if you eat liver more than once a week.
You can also contribute to your vitamin A intake by including good sources of beta-carotene in your diet, as this can be converted into vitamin A by the body. The main food sources of beta-carotene are: yellow, red and green (leafy) vegetables, such as spinach, carrots, sweet potatoes and red peppers,yellow fruit such as mango, papaya and apricots
