Myths and facts: seafood is brain food

Eating any type of fish just once a week increases brain health, a study has revealed. Just one fillet – grilled or baked – boosts grey matter, regardless of how much omega-3 fatty acid it contains. Experts have previously said the anti-oxidant effect of omega-3 fatty acids – found in high amounts in fish, seeds, nuts and certain oils – are associated with improved brain health. “Omega-3s [found in fish] are important, we think, because they reduce inflammation and help neurons function well,” says researcher Joseph Hibbeln of the National Institutes of Health.

But the new study hints that eating any fish has health benefits. The new research reveals that people who eat a diet including fish have larger brain volumes in areas associated with memory and cognition. The findings add to growing evidence that lifestyle factors, such as diet, contribute to brain health later in life. Scientists estimate that more than 80 million people will have dementia by 2040, which could become a substantial burden to families and the NHS. But evidence shows that consumption of 8 or more ounces of seafood per week can reduce the risk of death from cardiovascular disease, and some studies have linked a regular fish habit over a lifetime to a lower risk of cognitive decline as well.

‘Baked or broiled (grilled) fish contains higher levels of omega-3s than fried fish because the fatty acids are destroyed in the high heat of frying, so we took that into consideration when we examined their brain scans.’ The researchers found that people who ate baked or grilled fish at least once a week had greater grey matter brain volumes in areas of the brain responsible for memory – by four per cent – and cognition at 14 per cent.

In conclusion: eating seafood regularly can help increase cognitive functions and maintain cognitive health in old age. It helps memory and avoid cardiovascular diseases so it really is brain food. We at crabit recommend keeping seafood in your regular menu and consuming at least 1-2 times a week, to keep you mind even sharper than it is. We recommend trying our Red King Crab and Atlantic Cod for the nutrients and wonderful taste they possess.
