Eating fish may boost brain health

It’s well known that fish is good for you. Now, a study published in the American Journal of Preventive Medicine confirms that fish boosts brain health and may help prevent neurological disorders, such as Alzheimer’s.

Researchers from the University of Pittsburgh School of Medicine scanned the brains of 260 participants from the Cardiovascular Health Study—a larger 10-year heart health study—who recorded their dietary intake and had normal brain health. The participants noted how often they ate fish and how it was prepared. Baked and broiled fish have more omega-3 fatty acids than fried fish because they are destroyed by the fryer’s high heat.

The researchers found people who ate baked or broiled fish once a week exhibited larger brain volumes in areas linked to memory by 4.3 percent and those linked to cognition by 14 percent. People who ate fish were also more likely to have a college education.

It’s often thought that the high amount of omega-3s in fish benefits brain health. But the study noted it did not find a direct connection between consumption of omega-3s and brain changes. This led researchers to believe it’s a combination of lifestyle factors that affects brain health, rather than simply biological ones.
