How Foods & Nutrients Control Our Moods | Huberman Lab Essentials

About this video

Huberman explains emotions around food as a push-pull of attraction and aversion rooted in brain-body circuits, with the vagus nerve carrying information between gut and brain. He describes amino acids in food as precursors to neuromodulators: carbohydrate-rich foods favour serotonin, while his own low-carbohydrate, protein-focused lunch favours dopamine, acetylcholine and alertness, and evening foods containing tryptophan favour serotonin and sleep. Huberman discusses the omega-3 to omega-6 ratio and depression, citing a comparison using 1,000 milligrams a day of EPA, and presents a milkshake study in which the same shake blunted the hunger peptide ghrelin more when people believed it was high-calorie, illustrating top-down belief effects on physiology. Huberman frames these findings as evidence that food, belief and physiology continually inform one another through the brain-body relationship.

Key takeaways

• Huberman describes food’s amino acids as precursors to dopamine, serotonin and other neuromodulators.
• Huberman says he eats low-carbohydrate meals earlier in the day for alertness and tryptophan-containing foods in the evening for sleep.
• Huberman cites research linking a higher omega-3 to omega-6 ratio to less learned helplessness and discusses 1,000 milligrams a day of EPA in depression.
• Huberman describes how believing a shake was high-calorie blunted ghrelin more, even though both groups drank the same shake.
