Can Tryptophan Foods Increase Serotonin?

Studies that have tried to elucidate whether tryptophan foods serve to increase serotonin or not have reached controversial conclusions.

A study published in the JAMA Network states that one of the foods with tryptophan: chocolate is capable of increasing serotonin production instantly (8)

These authors explain that the combination of carbohydrates with tryptophan increases the concentration of said amino acid in the nervous system and stimulates the production of serotonin.

In contrast, the Journal of Affective Disorders states that the effects of chocolate consumption on serotonin levels are short-lived. (7)

When chocolate is consumed as a strategy to cure psychological disorders, there are more chances of generating a lousy habit than of curing depression.

Foods with tryptophan are essential for making the hormone serotonin. But its effects should not be overestimated.

Foods with tryptophan are helpful when there is a chronic lack of these in the diet. Including foods with tryptophan is an excellent strategy to balance biochemistry. However, it should not be posed as the solution to the problem.
