Certain foods indirectly influence the production of serotonin—commonly known as the "happiness hormone"—due to their high content of tryptophan, an essential amino acid used by the body to synthesize this neurotransmitter.

According to experts, serotonin plays a key role in regulating mood and is a vital component of mental health. However, they emphasize that diet only impacts its levels indirectly and is not the sole determining factor.
According to Healthline, the human body cannot produce tryptophan on its own, meaning it must be obtained through dietary sources. The most prominent sources include eggs, dairy products, soybeans, fish, nuts and seeds, as well as turkey.
Eggs: Egg whites contain proteins that can raise tryptophan levels in blood plasma, while the yolks provide important nutrients such as choline and omega-3 fatty acids.
Dairy Products: Solid cheeses, in particular, are highly rich in this amino acid.
Plant-Based Sources: Options like tofu and other soy products provide tryptophan, serving as excellent alternatives for those reducing their animal protein intake.
Fish: Varieties such as salmon stand out for containing omega-3 fatty acids and vitamin D alongside tryptophan.
Nuts and Seeds: These serve as an important source of both tryptophan and healthy fats.
Turkey: This is considered a complete protein, containing all essential amino acids.
Experts point out that combining tryptophan-rich foods with carbohydrates may temporarily increase the amino acid's availability in the body, though its overall impact on serotonin levels remains limited.
They also stress that factors beyond diet influence serotonin production, including physical activity, exposure to sunlight, and the health of the gut microbiome.
