Vitamin A that is found in colorful fruits and vegetables is called provitamin A carotenoid. In the United States, approximately 26% of this vitamin is consumed by men and 34% of the vitamin is consumed by women is in the form of provitamin A carotenoids Common provitamin A < a href="http://www.antioxidants-anti-aging-super-foods.com/carotenoids.html">carotenoids found in foods that come from plants are beta carotene, alpha carotene and beta cryptoxanthin Beta-carotene is made into retinol with the most efficiency.. Alpha-carotene and beta-cryptoxanthin are only half as efficiently as beta-carotene

Vitamin A found in foods that comes from animals is called a preformed Vitamin A. It is absorbed as retinol, one of the most active forms of the vitamin. The main sources include liver, meats chicken liver and whole milk. Retinol can be made into retinal and retinoic acid which are other forms of the vitamin in the body. As for the supplement forms of these nutrients, they’re often separate, but not equal.

The problem is that the pure form of vitamin A for body which is the preformed < a href="http://www.antioxidants-anti-aging-super-foods.com/vitamin-a-for-body.html">vitamin A variety, can create a number of nasty toxic effects if you take too much of it.

There have been some studies that indicate to much retinol or preformed Vitamin A can cause a high incidence of bone fracture. There was no evidence that the Vitamin A from < a href="http://www.antioxidants-anti-aging-super-foods.com/fruits-vegetables.html">fruits and vegetable which is in the form of beta carotene caused any side effects.

There is a growing body of evidence to suggest that the more foods we eat that contain beta-carotene, the less likely we are to develop certain types of cancer. It looks as if beta-carotene may help prevent cancers of the lung, stomach, and esophagus. Theirs is also some evidence that beta-carotene might lower the risk of developing cancer of the cervix and colon as well. Mouth and throat cancers are also be on the list.

"A reduction in the risk of lung cancer really stood out, followed by mouth and throat cancer," says Dr. Mayne, summing up some of his cancer research studies. "Again, beta-carotene and other carotenoids showed very strong preventive activity. In fact, an international group of researchers reviewed this data, and the evidence of a protective effect remains very compelling."Scientists are looking at how beta-carotene can produce a protective effect in our bodies. What they’ve found is that beta-carotene acts as an antioxidant Like vitamins E and C and many other nutrients, it can neutralize free radicals. These are the free-roaming, unstable molecules that can damage cells. Vitamin A for body is a staunch cell protector. Once into the fatty membranes around a cell called the mitochondria, it also guards against DNA damage in both the Mitochondria and the cell nucleus.

Beta carotene which is vitamin A for body may also help to regulate the proteins that enable cell-to-cell communication. Again from Dr Mayne, "Every cell in the body has the ability to communicate with its neighbors, as though it were calling out across the backyard fence," “This ability to communicate is thought to play a role in inhibiting cancer”.
