What is Beta Carotene? It is probably the best known of the
carotenoids, those warm colored pigments that give color to many
fruits and vegetables. The body converts Beta Carotene into vitamin A,
a nutrient recognized as vital to the growth and development of the
human body. A potent immune system booster and a powerful antioxidant,
Beta Carotene may counter the effects of cell-damaging molecules
called free-radicals. Eating plenty of fruits and vegetables is an
excellent way to supply your body with beta-carotene; however, if you
cannot fit them into your diet, Beta Carotene is sold in supplement
form.
Health Benefits of Beta
Carotene: There have been numerous studies on beta-carotene's
effectiveness for heart disease and cancer. Now researchers have been
exploring the nutrient's potential for treating chronic fatigue
syndrome, Alzheimer's disease, fibromyalgia, male infertility, and
psoriasis. Interestingly, low levels of beta-carotene and other
antioxidants have been linked to the development of cataracts, a
clouding of the eye's lens that impairs vision. Preliminary studies
also point to a possible connection between too little Beta Carotene
(and low levels of vitamins A and E) and subsequent development of
lupus, an autoimmune disorder.
No recommended daily
allowance (RDA) has yet been established for Beta Carotene, but about
10,000 IU of this nutrient fulfills the RDA for vitamin A.
Symptoms of a Beta
Carotene deficiency mimic those of a vitamin A deficiency: dry skin,
night blindness, susceptibility to infection. Such deficiencies are
seldom seen, however, even in people who don't eat fruits or
vegetables or take supplements, because so many other foods supply the
nutrient.
It is nearly impossible
to overdose on Beta Carotene because the body excretes what it doesn't
need.
