Healthy brains work even better with omega-3

Nutrients in food can have a profound effect on mental function and for the first time a study has shown that omega-3 fatty acids boost working memory, which is critical for reasoning and problem solving.

For the study a group of healthy young adults took omega-3 (DHA 750 mg and EPA 930 mg per day) for 6 months, underwent brain scans, had their blood omega-3 tested and were subject to a working memory task.

Notably before the test began the researches found a correlation between  their blood omega-3 and working memory, suggesting their dietary intake was already having an influence. And after taking the omeg-3 supplement their working memory significantly improved.

This finding indicates important benefits of omega-3 for brain function and highlights the significance of healthy eating for better mental health.

As the study investigators point out “previous studies in humans suggest that omega-3 deficiency is associated with impairment in mood and cognitive functioning. Some, but not all studies suggest that the supplementation of omega-3 in several neuropsychiatric disorders such as mood disorders, schizophrenia and attention deficit hyperactivity disorder holds promise as a primary or adjunctive therapy.”
