Carbohydrates that cause blood sugar levels to spike and fall rapidly could be a risk factor for central vision loss with aging. Central vision loss is one of the first signs of age-related macular degeneration (AMD), a leading cause of blindness among the elderly.
Diets high in carbohydrates that are quickly digested and absorbed, such as white bread, rice, potatoes, pasta, sugars and corn syrups is also suspected of being involved in the vision loss that sometimes accompanies diabetes.
The type of damage to eye tissue produced by these “fast” carbs could be similar in both AMD and diabetic eye disease.
