Omega-3 and a Better Brain


Nutrients in the foods you eat can have a profound effect on mind, memory and mental function. Omega-3 is one of those nutrients important in both the young and the old (and in between).


A group of healthy young adults (average age 22) took omega-3 fatty acids (DHA 750mg and EPA 930mg) daily for 6 months, underwent brain scans, blood testing and working memory tasks. Dietary sources of omega-3 already correlated with cognitive function and after the 6 months, working memory improved significantly, indicating pro-cognitive effects.

A clinical study of 281 people aged 65 years and older found that omega-3 fatty acids may help prevent age-related brain degeneration. Participants blood levels of omega-3 fatty acids and brain scans using MRI examinations were measured at the beginning and after 4 years. Participants with higher levels of omega-3 fatty acids were associated with lower grey matter atrophy, the areas of the brain important in mood, memory and cognitive function. Those with lower levels of Omega-3 had brain atrophy and a greater degree in memory decline and depressive symptoms. Other studies have been found to support these findings

Both studies highlight the significance of healthy eating for better mental health.
