2. protein: It is the material basis of intellectual activities and the main substance to control the process of brain cell excitation and inhibition. Representative foods are lean meat, eggs, fish and so on. Carbohydrate is the energy source of brain activity. After being decomposed into glucose in the body, it becomes an important energy source for the brain. Representative foods include miscellaneous grains, brown rice, brown sugar, cakes and so on.
