New research has discovered that switching from a high-glycemic (GI) diet to a low-glycemic diet can stop the progression of age-related macular degeneration (AMD).
The study by Tufts University found that for the same amount of total carbohydrate, high GI foods release sugar into the bloodstream more rapidly than low GI foods.
High GI foods include potatoes, white bread and rice, while examples of low GI foods are whole grains, lentils and fruit.
These included the loss of function of cells at the back of the eye, and of the cells that capture light.
Interestingly, switching from a high GI diet to a low GI diet could repair this damage to the retina.
