Newest Thoughts on Brain Food
Fish have long been regarded as “brain food” because of their high content of omega-3 fatty acids.Historically, omega-3 fats have been said to improve brain development and maintenance. Now, two new studies in the American Journal of Clinical Nutrition provide further evidence for the beneficial effects of omega-3 fats, including better performance or preservation of your brain function as you age.While numerous studies exist showing diets high in omega-3 fats lower your risk of dementia, these newer studies looked at the benefits of omega-3 fats among healthy people, with the hope that they would prevent progression to dementia. More than 5 million Americans have some form of Alzheimer’s disease, and just as many suffer from vascular dementia, so preventing and slowing the progression of neurodegenerative disorders is a public health imperative.The studies found:
A diet high in fish and fish products is associated with better cognitive performance
Higher levels of omega-3 fatty acids were associated with less decline in the speed-related cognitive domainsIt often takes decades for dementia to develop and brain volume to shrink. These studies of the benefits of omega-3 fats on brain function offer an opportunity for early intervention to maintain your brain function and slow progression to dementia.
