Histidine is one of the essential amino acids.
Histidine, similar to other amino acids, is found primarily in high-protein foods. Meat, poultry, fish, dairy and some grain products including rice, wheat and rye are therefore histidine-containing foods.
Yellowfin tuna, mackerel, sardines, skipjack and anchovies are excellent sources of histidine.
Other histidine-rich foods include soybean tofu, chicken, beans, eggs, buckwheat, corn, cauliflower, mushrooms, potatoes, bamboo shoots, bananas, cantaloupe and citrus fruits.
Histidine is readily available in a wide variety of foods. While it is easy for your natural histidine supplies to run short, consuming foods from each of the food groups will ensure you meet your daily histidine needs.
