Vitamin A and its need

Vitamin A is an essential fat-soluble vitamin which promotes our eyesight and helps us see in the dark. It also aids in the differentiation of cells of the skin (lining the outside of the body) and mucous membranes (linings inside of the body). Vitamin A is important as it helps the body fight off infection and sustain the immune system, but it also supports growth and remodeling of the bones. 

If your body doesn't receive the needed vitamin A, then you could become vitamin A - deficient, which can lead to night blindness, bone problems, reduced immune system and health, anemia and unhealthy skin. 

How much vitamin A is needed? 

The Recommended Dietary Allowance (RDA) for vitamin A is measured in retinol equivalents (RE), retinol being the active form of vitamin A. 
For men - 1000 micrograms of RE per day 
For women - 800 micrograms of RE per day

Where to get Vitamin A from?

Most people would first reach for their vitamin supplements, but the best way to get your vitamins is from your diet.

Richest sources of Vitamin A are:

Liver, fish, liver oils, milk, milk products, butter, eggs.

Other sources of Vitamin A are:

A variety of dark green and deep orange fruits and vegetables - carrots, sweet potatoes, pumpkin, spinach, butternut squash, turnip greens, bok choy, mustard greens, lettuce. 

We have to keep in mind that the absorption of vitamin A from the diet is improved when consumed along with some fat in the same meal. There is nothing better than a fresh salad full of vitamins. But if you don't like salads, don't worry. Vegetables can be prepared in different ways and can be served as a tasty appetiser or a side dish.
