I want to find food high in tryptophan, can you tell me which foods contain tryptophan?
Sure we can tell. Tryptophan is an amino acid so it is found in aliments containing a good amount of protein.
Contrary to the popular belief, it is not turkey food with the highest content in tryptophan. Egg white and dried spirulina are the foods with the higher content, followed by dried cod and raw soy beans. Cheese, yogurt, chicken, turkey, meat, fish in general and tofu also contain tryptophan.
Tryptophan is a precursor for niacin, one of the vitamins of the B group, which, in turn, is a precursor for serotonin, a neurotransmiter, and melatonin, a hormone that controls sleep-wake cycles.
It is said that insulin removes all amino acids form the blood with the exception of tryptophan, allowing it to get into the brain.
That is why a glass of milk with biscuits will help you sleep.
