Progression to both dry and wet forms of advanced AMD disease was 25% less likely among those eating a diet rich in omega-3 fatty acids.
People with advanced AMD who also consumed a low-GI diet, eating of foods that release their sugar more slowly, and who took supplemental antioxidant vitamins and minerals like vitamin C and zinc appeared to reduce their risk of disease progression by even more - by up to 50%.
Substituting five slices of wholegrain bread for white bread every day out of a total intake of 250g of carbohydrate might cut out almost 8% of advanced age related macular degeneration over five years, say the authors.
The top quartiles of consumption of omega 3 fatty acids DHA and EPA were only over 64 and 42 mg per day respectively. These aren't high doses.
While the omega 3 fatty acids help at all stages of the disease the vitamins and minerals actually seem to speed up the disease in its early stages.
And Elaine W. T. Chong, MD, PhD, of the University of Melbourne and colleagues, in their study of more than 6,700 58- to 69-year-olds, found those who consumed the most omega-3 fatty acids were at 15% lower risk of early-stage AMD. People who ate the most olive oil (at least 100 milliliters, or about seven tablespoons, per week) were about half as likely to develop late AMD as those who consumed less than 1 mL per week.
Dr. Chong and her team also found people who ate the most trans fat were 1.76 times more likely to develop late AMD during the study’s follow-up period.
Olive oil helps more than omega 3 fatty acids? Well, consume them both. I'm eating olives in my lunches now. Mu guess is that whole olives deliver a bigger benefit than the same number of calories as olive oil.
