Understand the serotonin/food myths. Unfortunately, there are a lot of myths surrounding food and increased levels of serotonin. These myths include: Foods rich in tryptophan automatically boost serotonin. This is false. Most foods that contain tryptophan, an amino acid, compete with other amino acids to be absorbed by the body's transport system. Eating a lot of turkey, which is rich in tryptophan, will not automatically give you more serotonin. Eating a lot of banana will automatically boost serotonin. Bananas do contain serotonin. That serotonin, however, is unable to cross the blood-brain barrier and be absorbed by humans.
