Fish
Fish is one of the healthiest foods for the human body and its powerful nutrients also contribute in the prevention of Alzheimer’s symptoms to some extent. Some potential nutrients of fish which might increase brain health include vitamin E, DHA, and polyunsaturated fatty acids. The n-3 polyunsaturated fatty acids protect against cognitive decline. Moreover, only one serving of fish per week can improve the brain health and functioning of neurons. Several studies observing the affects of fish consumption and prevention of Alzheimer’s report that the beneficial nutrients of fish more specifically n-3 fatty acids prevent the progression of Alzheimer’s.
