Some foods that increase serotonin levels in the body include free range turkey, wild fish and seafood, whey protein and sour cherries, according to Muscle Health Fitness. Each of these foods has a slightly different positive effect on serotonin levels.
Free range turkey contains a significant amount of tryptophan, an essential amino acid that is a building block for serotonin, reveals Muscle Health Fitness. When an individual eats a protein source high on tryptophan with a small side of carbohydrates, all the other amino acids are released from the body, leaving the tryptophan free to create serotonin. A variety of wild seafood items contain the essential fats EPA and DHA, which have been shown to relieve the symptoms of depression caused by low serotonin. Whey protein has not only been shown to regulate appetite and increase insulin sensitivity, allowing the body to better regulate blood-sugar levelss and avoid crashes, but also to increase the levels of plasma Trp-LNAA, an indirect signal of increased serotonin function in the brain, according to one study.
A good night's sleep is one of the best ways to restore the body's serotonin levels, asserts Muscle Health Fitness. Sour cherries are an excellent source of the hormone melatonin, one of the best-known and safest natural sleep aids, often also sold as a supplement.
