Eating one portion of omega-3 fatty acid-rich fish per week could halve your risk of developing a degenerative eye condition.
Research published in the American Journal of Clinical Nutrition adds weight to similar studies from Australia and the USA in finding that increased consumption of the fatty acids DHA and EPA can reduce the risk of developing wet age-related macular degeneration (AMD) by around 70 per cent.
Macular degeneration, which affects between 25 and 30 million people worldwide, is typically divided into two types: wet and dry. ‘Wet' AMD is often associated with sudden onset vision loss.
Conducted by lead researcher Astrid Fletcher from the London School of Hygiene and Tropical Medicine, the study recruited 105 people over the age of 65 with wet AMD, and over 2000 people to act as a control group.
When diets were compared, habitual consumption of one serving of oily fish per week showed a 50 per cent reduction in the risk of developing wet AMD. Those who consumed higher amounts of at least 300mg of DHA and EPA were deemed to be around 70 per cent less likely to develop the condition.
