Eating turkey makes people especially drowsy
Turkey contains tryptophan, an amino acid found in proteins and essential to the human body. Scientific studies show that sleep and mood are affected by tryptophan. However, turkey does not contain an exceptional amount of tryptophan. Chicken and beef contain about the same amount, and pork and cheese contain more tryptophan per gram than turkey. Because turkey is consumed with other foods, absorption of tryptophan from turkey is minimal, noted the authors. The myth likely stems from the fact that everyone feels drowsy after eating a large meal because the body is using energy to digest food and blood flow and oxygenation to the brain decrease.
