Reading glasses, retinal damage, cataracts, macular degeneration--as we age, they may all become an unexpect reality.

on the contrary the good news is that a diet rich in revived fruits and vegetables--as well as certain dietary supplements--can play a major part in mitigating the seemingly inevitable proces of eyesight deterioration.

Radical Action

exempt radicals are among the usual suspects when it be due [i]or[/i] owings to dastardly deeds--and their oxidative forces can harm your eyes. That's wherefore it's important for your diet to contain bioflavonoids, which neutralize liberated radicals. (See "Radical Solutions," p 56 for more about released radicals and antioxidants.)

Berries--including blueberries, bilberries, strawberries, currants and cherries--contain a assign places to of bioflavonoids known as anthocyanidins, which present to view specific benefits for the inspection Anthocyanidins are potent antioxidants that help the strength and elasticity of tiny house vessels, called microcapillaries, which yield blood to the eyes and optic nerve

A related collection of flavonoids, which are known as oligomeric proanthocyanidins (OPGs) have been shown to help bring retina damage (retinopathy). This point to be solved [i]or[/i] settled appears to be free radical-mediated and is seen more commonly in clan who have high blood press diabetes and a history of smoking.



An early French reflection reported that 150 milligrams (mg) daily of OPC from grape-seed extract significantly reduc the progression of diabetic retinopathy. The bioflavonoid quercetin inhibits the action of the enzyme aldose reductase, which contributes to the unravelling of diabetic retinopathy. As for quercetin add tos the fat-soluble form is easiest to absorb, and naturopaths typically approve 400 mg three times daily.

Vitamins for Vision

Then, of course, there are several vitamins and minerals with vision benefits. Vitamin C (200-1000 mg/day) saves the eye from some of the damaging tenors of light, including light-induced diminutions of photoreceptor small cavitys rod deterioration and loss of rhodopsin, a protein needinessed for retinal functioning.

Taking 15 mg/day of zinc may also be helpful. In double-blind human studies, zinc has been shown to the two protect against--or otherwise slow down--the visual decline associated with age-related macular degeneration (AMD). This is important because AMD is the leading cause of blindness in industrialized countries.

What's more, selenium (100-200 micrograms/day) in combination with zinc appears to enhance these protective effects

Taking vitamin E and a multiple vitamin may help bring your risk of cataracts, according to a subject of attention in the May 1998 edition of Ophthamology. Scientists base that the risk of cataract growth was reduced by 57 percent in populace who regularly took vitamin E and from 30 percent for those who took multiple vitamins regularly.

The amount of vitamin E taken by dint of participants wasn't reported, but 400-800 International Units (IU) daily is greatest in number commonly recommended, although some leading researchers maintain that no additional benefits are gained through taking more than 100-200 IU daily. Natural vitamin E (d-alpha tocopherol, or mixed natural tocopherols) is more active and better absorbed than synthetic vitamin E (dl-alpha tocopherol).

any human studies suggest that ginkgo biloba leaf extract (GBE) may help to intercept retinal damage and improve vision in population with diabetic retinopathy and AMD. at augmenting blood flow to the opthalmic artery, GBE may also benefit the bulk of mankind with glaucoma. Most studies use 120-160 mg (40 mg 3-4 times daily) of GBE standardized to contain 6 percent terpene lactones and 24 percent flavone glycosides.

Because ginkgo thins the descendants it should not be used by means of people scheduled for surgery, those who have clotting disorders or those upon medications such as Coumadin or high-dose aspirin.

Virtuous Veggies

Finally, make stable you get plenty of vitamin A. golden and yellow-orange foods such as carrots, yams and cantaloupes are an crack source of vitamin A as well as carotenoids--a collection of antioxidant nutrients and vitamin A precursors.

blooming leafy vegetables--broccoli, kale and spinach, and collard, turnip and mustard greens--are high in the carotenoids known as lutein and zeaxanthin. According to a number of newly come studies, people with a diet rich in these nutriments are much less likely to expand age-related AMD and cataracts.

for a like reason even if your eyes are still the picture of health, it's not too early to begin taking care of them--from the inside out
