How Can Diet And Nutrition Help To Prevent Blindness?

These options obviously have their place, but what is interesting is that for all three conditions, cataracts, glaucoma and macular degeneration, research has found that nutrition plays a very important role to prevent and delay progression of these diseases. With these conditions accounting for more that 68% of all visual impairment, nutrition has an important role in protecting vision.

Preventing Cataracts Through A Healthy Diet

For the onset of cataracts, a study in the early nineties pointed out that those people having a diet deficient in fruits and vegetables were 5.7 times more likely to develop cataracts than those not deficient in this food area. The studies suggested that the vitamin C, vitamin E and carotenoids from the foods were very powerful compounds with respect to their ability to protect the eyes and delay onset of cataracts.

Changing Our Diet To Avoid Glaucoma

Similarly, studies related to glaucoma found similar benefits from fruits and vegetables with risks of developing the disease being reduced by approximately 50 to 70 percent strictly based on diet. For those with the condition, vitamin A, chromium and Omega-3 fatty acids were found to reduce pressure within the eye while a vitamin C deficiency was found to increase the pressure. Clearly, inclusion of a reasonable amount of vegetables and fruits in our diet is an important part of protecting our vision.

Increasing Fruits and Vegetables To Reduce Macular Degeneration Risk

Very recently, studies have found the importance of nutrition with respect to the medical condition called Macular Degeneration. Macular Degeneration is a condition experienced mostly by older adults in which vision loss occurs in the center of vision. From the research, the scientists learned that the antioxidants found in a number of foods protect the eyes by reducing the amount of damaging oxidants in the eye. The oxidizing chemicals are formed when light hits the neurons in the eye and will kill neurons when concentrations are too high, causing permanent loss of vision. In one of the studies, the rate of degeneration was reduced by 20% simply by a change in diet. Again the diet described included more daily fruits and vegetables, but additionally nuts.
