4. Bananas
According to Zuckerbrot, “bananas are high in complex carbohydrates, which contain serotonin, the feel-good chemical.” She adds that “complex carbohydrates also improve the transport of tryptophan into the brain, where it is converted to serotonin.” Bananas also contain the amino acids called tyrosine and phenylalanine.
“Tyrosine leads to balanced levels of dopamine in the brain and aids in the reduction of body fat—and who doesn’t want to lose weight!?—while phenylalanine is used to form tyrosine.” Plus, people who consume bananas regularly noticed an improved digestive health.
