Andrew Huberman (solo): Stanford professor of neurobiology and ophthalmology and host of the Huberman Lab podcast. This is a solo Essentials episode with no guest.
What this episode covers
In this Huberman Lab Essentials episode, Andrew Huberman covers the food-derived compounds that support brain structure and cognition, ranking them by importance: essential fatty acids (EPA/DHA omega-3s), phosphatidylserine, choline, creatine, anthocyanins from dark berries, and glutamine. He explains that fat, not glucose, is the most critical structural element of neurons. He then shifts to the neuroscience of food preference, describing three signals that drive food choice: taste on the tongue, subconscious gut nutrient-sensing neurons that trigger dopamine, and learned belief about what a food does. He shows how preferences are 'soft-wired' and can be retrained, and how belief alone (not placebo) measurably changes insulin and blood glucose responses.
Recommended on this episode
Creatine Monohydrate
(generic supplement)
“So, I personally take creatine, 5 g per day, and have for a very long time.”— Andrew Huberman
Rethinking Food Reward (Annual Review of Psychology, 2019)
Ivan de Araujo, Mark Schiller, Dana Small
“there's a wonderful review written by Ivan de Araujo... It's called Rethinking Food Reward and it was published in the Annual Reviews of Psychology.”— Andrew Huberman
Also referenced (named, not recommended)
Phosphatidylserine
(generic supplement)
“For those of you that are interested in supplementing with phosphatidylserine, it's a relatively inexpensive supplement”— Andrew Huberman
EPA / Omega-3 fatty acids
(generic supplement)
“supplementing with omega-3s to get above that 1.5 g and ideally up to 2 or even 3 g per day of EPA can be very beneficial for cognitive function”— Andrew Huberman
Choline
(generic supplement)
“most people should probably strive to get somewhere between 500 mg and a gram of choline per day”— Andrew Huberman
Alpha-GPC
(generic supplement)
“I generally consume these things like EPAs, creatine, alpha GPC to set a general context of support for my neurons, for my brain”— Andrew Huberman
L-Glutamine
(generic supplement)
“For people that supplement with glutamine, generally they will take anywhere from a gram as much as 10 g per day.”— Andrew Huberman
Big reveals from this episode
- Argues fat, not glucose, is the single most important food element for brain function because neuron membranes are built from structural fat.
- Huberman admits he takes 5 g creatine daily but has never come off it, so he can't personally vouch for a noticeable benefit.
- Explains 'neuropod cells' in the gut sense amino acids, sugars and fats and trigger dopamine release entirely below conscious awareness.
- Pairing an artificial sweetener with blood-glucose-raising food can later make the sweetener alone spike insulin.
- Alia Crum's milkshake studies showed identical shakes produced different insulin and glucose responses based purely on what subjects were told.
- Claims you can retrain your palate to enjoy a healthy food within about 7 to 14 days by pairing it with metabolism-shifting food.
Worth remembering
- Most people get enough omega-6 but not enough omega-3; Huberman suggests 1.5 to 3 g of EPA per day for cognition.
- Egg yolks are a top dietary choline source because an egg contains everything needed to grow an organism.
- Target choline intake is roughly 500 mg to 1 gram per day.
- Dark thin-skinned berries (blueberries, blackberries, currants) contain anthocyanins with real data supporting brain benefits.
- Gut glutamine-sensing neurons send satiation signals that can help offset sugar cravings.
- What your brain actually seeks when eating is not taste or dopamine but the metabolic activity sweet foods predict.
- The milkshake effect is a 'belief effect,' distinct from a placebo effect, directly altering physiology like blood sugar.
- Best to consume artificial sweeteners away from foods that raise blood glucose to avoid disrupting insulin regulation.
