Trials in human patients with macular degeneration, conducted by Dr. Yves Sauve and his team from the University of Alberta, have found those who have the highest level of DHA will have the lowest severity and slowest progression of macular degeneration.
“We don’t have any studies other than what we’ve found with DHA that can prevent that accumulation,” Dr. Sauve said.
He suggested everyone should increase their DHA levels by eating oily fish like salmon, or taking fish oil capsules with every meal. Because fish do not make the DHA but actually obtain it through micro-algae, vegetarian alternatives are also available in capsules.
Dr. Suave said a healthy diet should contain a one-to-one ratio of Omega-6 to Omega-3. The western diet is exceptionally high in processed foods containing large byproducts of soy and corn, which are high in omega-6 fatty acids. He said as well as benefiting vision, Omega-3 fatty acids have proven beneficial to human health in areas such as cardiovascular health and mental health in terms of severe depression.
