Vitamin A

Vitamin A is a fat soluble micronutrient essential for healthy vision, cell reproduction, wound healing, immunity and other crucial bodily functions.

A study by the university of Arizona found that vitamin A has a protective affect against many types of cancer, according to M. Colgan in his book, The New Nutrition. It is found in animal products, but can be manufactured by the body from its precursor beta carotene (found in vegetables). As an antioxidant vitamin A protects cell membranes and fatty tissue, helps repair damage caused by air pollutants and boosts the immune system.
