According to U.S. Department of Agriculture data, 55 percent of Americans do not obtain adequate levels of vitamin A. The vitamin provides many health benefits.
A-MAZING HEALTH BENEFITS
Night blindness. One of the classic signs of vitamin A deficiency is night blindness, characterized by difficulty seeing in the dark or being blinded after exposure to a glaring light (e.g., oncoming headlines). Most serious eye diseases, including cataract, macular degeneration, and glaucoma, are associated with night blindness.
Retinitis Pigmentosa. Doctors commonly recommend 15,000 IU of vitamin A daily for people with retinitis pigmentosa, an inherited disease that accelerates the breakdown of the retina. A recent study found that adding 12 mg of lutein daily further slows vision deterioration in people with this disease.
Cancer protection.Researchers have established the benefits of vitamin A in protection against epithelial cancers, including cancers of the breast and ovary. (Carcinomas are epithelial-related cancers.) In one recent animal study, vitamin A protected against radiation- and estrogen-induced breast cancers. Vitamin A promotes normal differentiation of cells, whereas cancer cells are undifferentiated.
Infection resistance. A 1928 article in the British Medical Journal described vitamin A as the “anti-infective” vitamin—so impressive was its effect on countering bacterial infections, including those of the lungs and urinary tract.
