Turkey

Bone health. Brain health. Muscle health. An excellent source of protein, which is essential for bone and muscle health, turkey is probably best known nutritionally for its abundance of tryptophan. This is one of the 9 essential amino acids. Essential amino acids cannot be made by the body. As a result, they must come from food. Tryptophan helps the body produce serotonin, a neurotransmitter that controls mood. Low serotonin levels have been linked to a variety of issues, including depression and eating disorders.
