A compilation study from Tufts University, University of Wisconsin, and the EMMES Corporation researched the effects of taking the AREDS supplement plus omega-3 and reducing dGI (dietary glycemic index) on AMD (age-related macular degeneration). dGI is a numerical index given to a carbohydrate-rich food that is based on the average increase in blood glucose levels occurring after the food is eaten.
The trial spanned 8 years and studied 3,000 eligible AREDS AMD trial participants.
Looking at the risk of advanced AMD, the study found that the AREDS supplement plus higher intakes of omega-3 (DHA and EPA), and reducing dietary glycemic index (dGI) helped reduce progression of the disease.
