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.
