Can blindness be prevented through diet?

Increasing intake of the omega-3 fatty acids DHA and EPA, found in popular fish-oil supplements, may protect against blindness resulting from abnormal blood vessel growth in the eye, according to a study in Nature Medicine. The study was done in mice, but a clinical trial at Children's Hospital Boston will soon begin testing the effects of omega-3 supplementation in premature babies, who are at risk for vision loss.

   People consuming diets with a higher glycemic index than average were at greater risk of developing advanced age-related macular degeneration, report researchers at Tufts. The researchers suggest that twenty percent of cases of advanced Age-Related Macular Degeneration might have been prevented if individuals had consumed a diet with a glycemic index below average.

   The obesity epidemic has spawned not just diabetes, but another serious public health problem: a surge in fatty liver disease, which can lead to cirrhosis and liver failure. Now, research suggests that limiting consumption of high-glycemic-index carbohydrates can prevent the condition in mice. A clinical trial is now testing this idea in overweight adolescents, as well as the possibility of reversing fatty liver disease through diet.

5. A novel way found to prevent protein plaques implicated in Alzheimer's
   11-18-2007 · EurekAlert!
   For unknown reasons a protein called amyloid beta aggregates into toxic plaques in the brain, killing neurons. These plaques are one of the hallmarks of Alzheimer's disease. Now two new animal studies show for the first time that the deadly transformation of amyloid beta into plaques can be prevented through an interaction between amyloid beta and another protein called cystatin C.

9. Blinded by sFRP-1: A WNT signaling protein plays a key role in glaucoma
   02-14-2008 · EurekAlert!
   Increased pressure in the eye is a major risk factor for glaucoma, one of the main causes of visual impairment and blindness in the world. It is thought that impaired outflow of fluid from the eye causes glaucoma-associated increased pressure in the eye, and the authors of a new study have now shown that increased expression of the protein sFRP-1, an inhibitor of cell signaling through WNT proteins, seems to be responsible for this.
