    Can nutrition help us prevent some neurodegenerative diseases? Yes. According to an article recently published in the journal Neurology, a diet rich in fish and vitamins can protect the brain from the contraction associated with Alzheimer's disease.

    The study was conducted on people of an average age of 87 years in which they counted the levels of certain nutrients through blood tests. According to the data, people who had higher amounts of vitamins and omega-3 fatty acids -present mainly in fish- obtained higher scores in memory tests and cognitive abilities. By contrast, the people who obtained the worst results were those with high rates of trans fat in the blood, which are associated with diets where fast food abounds, fried, frozen and confectionery products. These people are more likely to suffer reductions in brain volume related to Alzheimer's disease.


    This study was the first to use biomarkers of nutrients in the blood to analyze the effects of diet on the risk of neurodegenerative diseases. In addition, the authors incorporated other variables such as age, blood pressure or number of years of education, which also proved to be decisive in the mental abilities of the participants.
