Fish contain higher protein than beef. However, if after eating a lot of fish, you feel migraine and the increasing of blood pressure, stop eating it immediately. Fish turned out to contain histamine, a type of essential amino acids needed children and infants, but not an adult. In adults, histamine has a psychoactive (attacking nerve) and vasoactive (attack the circulatory system) effect. In people who are sensitive, histamine causes migraine and increases blood pressure.
