How does the brain really work?

Over the last decades, epidemiological and interventional studies have shown that nutrition and some specific nutrients impact brain and cognitive development and brain health, functionally and structurally. Moreover, managing nutritional habit through specific diet has a positive impact on health. Some specific nutrients, such as the polyunsaturated omega-3 fatty acid docosahexaenoic acid (DHA) have also been shown to promote brain development and support cognitive function during aging. However, our understanding of how nutrition affects brain function remains very limited.
