Did you know that the brain is the highest fat organ? But unlike those contained in adipose tissue, they do not serve as a reserve: they enter into the composition of the sheaths that protect neurons. We owe this structure in particular to fatty acids omega-3, of which oily fish are one of the best sources. A deficiency also induces slight neurophysiological dysfunctions and particularly affects cognitive performance.

Le selenium contained in this type of fish would also be able to prevent cognitive aging by preventing the formation of free radicals. In addition, studies have shown the importance of starchy foods with a low glycemic index (beans, whole wheat, beans, hummus, lentils, etc.) to maintain intellectual performance over long periods of time (such as an exam, for example). Finally, do not skimp on foods rich in antioxidants(blueberries, grapes, vegetables, green tea…), especially when we know that the human brain is a very greedy organ: the degradation of its favorite resource (sugar) releases many free radicals responsible for aging.
