Milk is rich in protein and mineral calcium, which is an important source of nutrition for the brain. Protein is the raw material of human body, and it is also one of the important elements to make brain cells and neurotransmitters, which can help the development of the brain. Calcium can inhibit abnormal discharge of brain cells, stabilize mood, promote good sleep, reduce physical fatigue and enhance resistance.

5. Fish
60% of brain cells are composed of unsaturated fatty acids, of which DHA is the most important. DHA is an important component of brain nerve cells, which is very important for the conduction of brain neurons and the growth of synapses, and can enhance brain intelligence, memory and concentration. The content of DHA in terrestrial meat and vegetables is almost zero, and only exists in marine meat, among which deep-sea fish are the most abundant, especially orbital fat and fish skin. However, large deep-sea fish are at the top of the food chain and have accumulated too much heavy metals in their bodies, so they should not be eaten too much. On the contrary, saury with higher DHA content than salmon is more suitable.
