New Study Further Supports the Role of Omega-3s in Reducing Risk of Alzheimer’s disease

Published:

About the Study

A study published in the Journal of Alzheimer’s Disease entitled Impact of Omega-3 Fatty Acid Supplementation on Memory Functions in Healthy Older Adults was recently conducted to further analyze the potential benefits of omega-3s for brain function, specifically learning and memory function. In this double-blind placebo-controlled study, 44 cognitively healthy men and women aged 50–75 years received either a long chain polyunsaturated omega-3 supplement (2,200 mg/day of omega-3s) or a placebo for 26 weeks. Before the study, memory tasks were tested, and reevaluated when the study concluded. Auditory Verbal Learning Tests (AVLT), dietary habits, omega-3-index (omega-3 blood levels), and other blood-derived factors were also assessed.

 

What did the study find?

The researchers found that the group that took the omega-3 supplements had a greater improvement in their memory, specifically with the recall of object location, versus the group that took the placebo. Additionally, the group that took the omega-3 supplements had a significantly greater omega-3 index than that of the placebo group.


What does this mean to me?

Alzheimer’s is a growing problem in Canada, with 1.1 million Canadians expected to have the disease in the next 25 years[1]. There is currently no treatment for Alzheimer’s disease and the exact cause still remains unknown.

This study adds to the growing body of scientific evidence that omega-3 fatty acids can have a positive effect on memory and brain function. It further supports longtime research that shows prevention of cognitive decline through a diet high in omega-3s and through omega-3 supplementation is key in helping to reduce the risk the Alzheimer’s disease and plays an important role in maintaining optimal brain health.
