Women who consume larger quantities of fish may have healthier brains as they age. A recent study published in the peer-reviewed journal Neurology revealed that women who had higher than normal levels of omega-3 fatty acids in their blood — which are commonly found in fish — tended to have larger overall brain volume than their peers with lower levels.
"This recent study looked at the connection of fish oil rich diets and some of the brain changes associated with Alzheimer's disease." says Heather M. Snyder, Ph.D., of The Alzheimer's Association
."This work adds to a larger body of literature where we have seen mixed information regarding a potential benefit of fish oil, and adds to the research regarding the possible connection of specific diet and reduced risk associated with Alzheimer's disease. The Alzheimer's Association supports an overall balanced diet, as research suggests this may be the most beneficial for healthy aging, and possibly reducing risk associated with Alzheimer's disease. Further, the strongest research we see consistently in the field is the connection between physical activity and a reduced risk of Alzheimer's disease."
