Eating a healthy diet reduces a person"s risk of developing life-altering eye diseases, a study has suggested.
Scientists at the Laboratory for Nutrition and Vision Research in Boston have found that regularly consuming a combination of particular nutrients and foods that have a low glycemic index can protect people from age-related macular degeneration (AMD).
A food"s glycemic index is determined by how fast the carbohydrate it contains causes a spike in blood sugar levels.
In a study used by the researchers, the dietary intake of more than 4,000 men and women aged between 55 and 80 was analysed.
The nutrients that were found to be most protective against AMD in combination with the low-glycemic-index diet were vitamins C and E, zinc, lutein, zeaxanthin, and the omega-3 fatty acids DHA and EPA.
A report published in an issue of Archives of Ophthalmology revealed that smoking and low levels of cholesterol are linked to the occurrence of AMD.
