How Foods and Nutrients Control Our Moods

About this video

Huberman explains how foods and nutrients control mood through serotonin and dopamine pathways. He directs listeners to examine.com for PubMed-linked evidence, reporting from that source that 5-HTP produces a notable decrease in appetite across three studies in his account, with a consequent decrease in body weight and a minor increase in cortisol, while cautioning against chronic use and noting he is not recommending it. Huberman explains the appetite effect as consistent with seeking foods for serotonin: if serotonin is sufficient, there is less reason to eat more. On dopamine, Huberman discusses Mucuna pruriens, a velvet bean, explaining that inside the bean is L-DOPA, the chemical precursor to dopamine, while its surface carries serotonin that irritates skin. He marvels that such compounds are available over the counter, while stressing he describes their effects to reveal what acute dopamine increases do, not to encourage use. Huberman also frames foods rich in L-tyrosine as biasing dopamine-related effects.

• Huberman describes Mucuna pruriens as containing L-DOPA, the precursor to dopamine.
• Huberman stresses he describes supplement effects for understanding, not as encouragement to take them.
• Huberman frames L-tyrosine-rich foods as biasing dopamine pathway effects.
