Dopamine and norepinephrine are two other important brain chemicals. They produce a feeling of alertness,an increased ability to concentrate,and faster reaction times. There are two possible ways this happens:(1) serotonin production is blocked by the consumption of protein-rich foods,resulting in increased alertness or concentration,or (2) levels of dopamine and norepinephrine are increased by the consumption of protein-rich foods.
Foods rich in protein are meat,milk,eggs,cheese,fish and beans.
