The brain is the fattiest organ in the body. 60% of its dry weight is fat - the myelin sheath that transmits nerve signals is made of it. Omega-3 fatty acids (especially DHA) are critical for brain health. Fish, walnuts, flaxseed are known as "brain food" for this reason. Low-fat diets can negatively affect memory and concentration.
