Diet to strengthen memory and prevent Alzheimer's risk

Diet to strengthen memory and prevent Alzheimer's risk

According to a 2012 US study, the intake of omega 3 fatty acids would be decisive

The 9 foods richest in Omega 3

Including nuts, fish, poultry and almonds in your daily diet, all foods characterized by the presence of omega-3 polyunsaturated fatty acids, can help strengthen memory and prevent Alzheimer's (this disease, in 2030, will affect over 74 million people in the world according to the World Alzheimer Report 2015). This is the conclusion reached by a study published in 2012 and conducted by an active team at Columbia University in New York.

The scientific work just mentioned, published in the pages of the journal Neurology, is a cross-sectional study that started with the aim of clarifying the associations between diet and the presence, at the plasma level, of beta-amyloid protein, in turn associated with problems of memory and the onset of Alzheimer's (the senile plaques that characterize the brain of those suffering from this neurodegenerative pathology are aggregates of beta-amyloid protein).

Returning to the study, we recall that the researchers who conducted it recruited 1,219 subjects over 65 and cognitively healthy. Using linear regression models, the researchers monitored the intake of certain nutrients, specifically saturated fatty acids, monounsaturated fatty acids, omega-3 and omega-6 polyunsaturated fatty acids, vitamin E, vitamin B12, beta-carotene, folic acid and vitamin D.

At the follow-up, it was possible to identify an association between the intake of omega-3 polyunsaturated fatty acids and lower levels of beta-amyloid protein (the data on this last point were obtained following the execution of tests of the blood, which allows you to easily get a picture of the situation).

Columbia University experts, by monitoring the responses to questionnaires on eating habits administered to the subjects included in the sample, were able to identify some of the foods characterized by the presence of omega-3 fatty acids included in the diet. Among the aforementioned sources it is possible to mention meals characterized by the content of salad, but also margarine, fish, fruit and poultry.

The study in question represented the umpteenth confirmation of how the Mediterranean food model – characterized by the presence, in the typical menu, of large quantities of plant-based foods and the intake of good fat sources – represents a valid alternative to contribute to slowing of cognitive decline.

We conclude by pointing out that, for specific references on what to eat to prevent Alzheimer's, it is advisable to ask your doctor for advice.
