10 Facts About Vitamin A

Vitamin A is essential for vision, immune function, and skin health. It supports growth and development, playing a vital role in overall well-being. Here are the 10 facts about vitamin A:1. Vitamin A was given the first letter of the alphabet for a name because it was the first vitamin to be discovered.

2. It was found that vitamin A has a large number of uses in the body including keeping eyes healthy, aiding cell growth and also helping boost the immune system.

3. Vitamin A is not only absorbed directly but it is also created by the body by converting beta carotene into vitamin A.

4. Vitamin A itself is found in a number of foods such as Beef liver (cooked), Cod liver oil, Salmon (cooked), Cheddar cheese, Eggs, Oysters (canned), Whole milk, Sweet potato (baked), Butternut squash (baked), Collard greens (cooked), Carrots (cooked), Romaine lettuce (raw), Swiss chard (cooked), Spinach (cooked), Mango, Cantaloupe, Watermelon, Apricot, Nectarine, Guava, Passion fruit, Tangerine and Grapefruit.

5. The Beta carotene that the body can convert into vitamin A is found in many fruits and vegetables, especially the red, orange and green colored ones.

6. The most important point to remember is that consuming too much pure vitamin A can be toxic. It is essential not to exceed the recommended daily allowance for vitamin A. The actual recommended allowance of vitamin A varies depending on a persons age, sex and other factors.

7. Many people will remember being told that eating lots of carrots helps you to see in the dark. Other foods which have high levels of beta carotene that can be converted to vitamin A include tomatoes and dark green leafy vegetables, such as spinach.

8. Beta carotene is not only used to form vitamin A, but it is also a powerful antioxidant in itself. None of the beta carotene that is absorbed is wasted as any excess after conversion to vitamin A is used to fight the harmful free radicals within the body.

9.Vitamin A also helps fight infections and illnesses by helping tissues that line various parts of the body, including the eyes, mouth, nose, throat and lungs, to grow and also to repair them if they are damaged to prevent infection.
