Beta-carotene is an inactive form of vitamin A that is found in many fruits and plants. Because it is so similar to vitamin A, Beta-carotene provides a lot of the same benefits that vitamin A does.

One of vitamin A's most well known health benefits, improved night vision, is also provided by beta-carotene. Taking healthy doses of either vitamin A or beta-carotene can improve vision, night vision, and can also protect against vision problems like cataracts.

Like vitamin A, beta-carotene is an antioxidant.

Antioxidants, which can be found in many fruits, vegetables, and supplements, neutralize free radicals, which are naturally occurring unstable molecules that can cause damage to healthy cells in the body.

Free radicals can contribute to a number of ailments, including heart disease, neurological disease, and many types of cancer. Free radicals are also partially responsible for the physical aging of the human body. Taking antioxidants like beta-carotene can help protect against free radicals, and in turn help prevent all the health problems that free radicals cause.

Specifically, beta-carotene has been shown to help with lung cancer and oral cancer, but because of its antioxidant properties, it is likely that beta-carotene could be used to help with many types of cancer. One caveat to this, however, is for smokers. Research has shown that smokers who take beta-carotene supplements actually have an increased chance of developing lung cancer, so smokers should avoid taking beta-carotene.

For those looking to increase their beta-carotene intake, it can be found in a wide variety of fruits and vegetables. Beta-carotene actually has a red-orange pigment, so foods that are red, orange, or yellow like papayas, yams, mangoes, and carrots will contain high amounts of beta-carotene.

Around the Web, learn more about the relationship of beta carotene and Vitamin A, its history, food sources and controversial studies suggesting its possible use in lung cancer treatment, along with recent studies warning that too much beta carotene may actually increase cancer risk ...
