Walnuts help to prevent age-related cognitive decline

Eating nuts reduces the risk of cardiovascular disease as it improves cholesterol levels and blood pressure. Of all nuts, walnuts have been studied the most and have been demonstrated to be beneficial for health, due to their high levels of antioxidants and high content of alpha-linolenic acid, an omega-3 polyunsaturated fat of plant origin. Furthermore, in the PREDIMED study conducted by, among other institutions, a team from the Hospital Clinic of Barcelona, ​​ the scientific data indicates that a Mediterranean diet complemented by a supplement of walnuts is linked to better cognition and less cognitive deterioration associated with age. A possible explanation for these protective effects is the high content in walnuts of alpha-linoleic acid, a fat that has been linked to better brain plasticity. It has also been suggested that the beneficial effects of a Mediterranean diet with a supplement of walnuts may be associated with their high content of phenolic compounds, antioxidants that could counteract the process of oxidation in the brain as well, and thus limit its neurodegeneration.
