Formation of cataracts
Cataract formation is believed to involve damage to lens protein by free radicals, causing the lens to lose its transparency. Cataract progression could be slowed with regular consumption of supplemental antioxidants, in particular vitamin E, vitamin C, and the carotenoids. It is estimated that if cataract development were delayed by 10 years as a result of increased antioxidant protection, the number of cataract surgeries performed in the U.S. would decrease by more than half (Percival, 1998).
Antioxidants and cataracts.
Cataract removal is the most common operation in the U.S. (1.2 million per year) with costs of over 3 billion dollars (Ames et al, 1993). There is evidence that cataracts have an oxidative aetiology and that dietary antioxidants can prevent their formation in humans. Five epidemiological studies examining the effect of dietary antioxidants on cataracts revealed strong preventative effects of ascorbate, tocopherol, and carotenoids. Those individuals taking daily supplements of ascorbate or tocopherol had about one-third the risk. Smoking, a severe oxidative stress, is a major risk factor for cataracts and radiation, an oxidative mutagen, is well-known to cause cataracts (Ames et al, 1993). Eye proteins show an increased level of methionine sulfoxide with age and proteins in human cataracts have over 60 percent of their methionine residues oxidised. Dietary antioxidants and a decrease in smoking are the most promising preventative strategies against cataracts.
AIM Proancynol 2000®
AIM Proancynol 2000® combines the proven antioxidants found in green tea and grape seed extracts with powerful antioxidant "newcomers" N-acetylcystiene and alpha-lipoic acid, as well as rosemary extract, selenium, and lycopene.
Treatment and prevention
A cataract is a progressive clouding of the eye lens, that interferes with light passing through the retina. This leads to a gradual blurring or dimming of vision. Normal activities like reading may become more difficult while driving a car can become dangerous. Cataracts can cause light glares, halos around lights, or even double vision. As the cataract develops, new eyeglass prescriptions may become necessary.
Currently, there are no medical treatments that reverse the development of cataracts. Once formed, the only one way to attain clear vision again, is to physically remove the cataract from the eye. For this reason, preventative strategies against cataracts, as supplemental antioxidants, are important.
Spinach, kale, broccoli, and other foods rich in the carotenoid lutein may cut the risk of cataracts, according to two major studies at the Harvard Medical School. Johanna Seddon and colleagues monitored more than 77,000 women in the Nurses' Health Study and more than 36,000 men in the Health Professionals' Follow-up Study. After 12 years, 1,471 cataracts were extracted from the women and after eight years, 840 cataracts were extracted from the men (Holly, 2003).
Those who ate the most lutein had about a 20 percent lower risk of cataract surgery than those who ate the least. Spinach has a fairly good ORAC score at 1260.
AIM Just Carrots®
Beta carotene is a potent antioxidant. AIM Just Carrots® has one of the highest sources of natural beta carotene - up to 700 percent of the U.S. government's Recommended Daily Allowance (RDA). Drinking one glass of AIM Just Carrots® provides you with 35,000 International Units of beta carotene.
AIM BarleyLife® is as effective as the Chinese wolfberries as an antioxidant, with an ORAC value of 25,500! AIM BarleyLife® is bursting with nutrition. It contains 2½ times the beta carotene found in an equivalent weight of raw carrots and about 25 times that found in an equivalent weight of raw broccoli. Beta carotene is an important antioxidant known to protect cells.
