Dr. Sara Gottfried likes to almost start with nutritional testing when phenotyping patients, especially in your 20s, because micronutrients play a huge role in terms of hormone production.

Dr. Sara Gottfried describes using the message of painful periods to investigate root causes, like inflammatory tone, rather than defaulting to oral contraceptives.
Dr. Sara Gottfried says it is essential to understand what your grandmother went through, and to know your mother's and grandmother's hormone health history, especially trauma and intergenerational trauma, because it affects the endocrine system and cortisol signaling.
Jeff Cavalier advises getting fish from a reliable source, because all fish — farm-raised or wild-caught — carries concerns about heavy metal contents and high levels of mercury.
None stated.
The question of what NOT to eat to protect memory is far easier to answer than what to eat. Omega-3 fatty acids have a fairly decent literature supporting benefits for memory and cognition. A researcher at UC Santa Barbara (name to be added in show notes) has studied omega-3 supplementation during pregnancy and its effects on brain size and function in human offspring. Omega-3s, polyphenols, and sufficient protein are identified as the established critical players for brain health.

Jeff puts his walnuts in his oatmeal every single day, or pairs them up with the omega-rich fish he talked about eating before, to consolidate daily foods.
Huberman describes apigenin as a derivative of chamomile that acts as a bit of an anxiety-lowering compound, useful prior to sleep for turning off thinking and reducing rumination, problem-solving, and future anticipation. He notes that reducing rumination, problem-solving, and future anticipation is a requirement for falling asleep.
Huberman explains he is not a fan of melatonin supplementation for a couple of reasons: melatonin induces sleepiness but does not keep you asleep, so people often fall asleep then wake and have trouble falling back asleep; melatonin supplements almost always contain amounts that far exceed normal endogenous biological levels; melatonin can impact not just sleep but other systems in the brain and body; and while it's true that we produce less melatonin as we age, he remains discouraged about its use.
Huberman describes an anti-pattern: people will take melatonin, fall deeply asleep, and then wake up and have trouble falling back asleep.

The cholinergic stimulation from alpha-GPC and the dopaminergic stimulation from L-tyrosine lead to increased focus without the stimulant-based alertness experienced with caffeine. Huberman notes some products and people combine caffeine, alpha-GPC, and L-tyrosine in a single formula, and he is not suggesting that's good or bad.
Huberman advises getting behaviors and nutrition correct before thinking about supplementation for hormones. He explains that getting morning sunlight increases cortisol levels, cortisol should be elevated early in the day for focus, alertness, and immune function, and cortisol levels should be low at night so growth hormone and testosterone can be elevated at night and early morning.
Getting morning sunlight elevates cortisol levels early in the day, which supports focus, alertness, and immune function. Keeping cortisol low at night allows growth hormone and testosterone to be elevated at night and early morning.
Dr. Chris Thompson recounts the earlier claim that a morning cortisol spike makes you more likely to store food eaten in the morning, says that may not be so true, and suggests it might be better to eat earlier and start the fasting window in the afternoon.

Andrew Huberman notes that whether people with gut issues should avoid intermittent fasting is highly contextual, and that based on the mucus-layer mechanism it stands to reason one might want to avoid an empty stomach for very long periods outside of sleep.

Dr. Chris Thompson describes how during the POEM procedure, vessels in the tunnel are hard to see and hitting one is a risk — AI can see those vessels through pattern recognition and color them so the surgeon avoids them.
Dr. Thompson says he would rather spend one long day under anesthesia getting completely non-damaging biopsies of every major organ than walk into the clinic at 72 discovering symptoms, noting that people typically end up either diagnosing themselves by symptoms, dropping dead, or being diagnosed by someone else.

For about a hundred years, the same eye procedure was done without fluorescein, so eye surgeons had to essentially guess based on intuition and training what tissue to preserve and what was healthy versus unhealthy. A drop of fluorescein — an innocuous liquid — creates contrast so the eye doctor can see what is what and not cut the wrong tissue. Simple-seeming technologies like this have improved margins of safety and outcomes tremendously.

A duodenal liner device is placed endoscopically — a stent springs open, anchors in the first part of the small bowel, and covers/protects the duodenum. Food travels inside the sleeve while digestive secretions and enzymes travel on the outside, not mixing for a few feet down. In clinical trials Dr. Thompson participated in, diabetics had a one-point drop in A1C and participants lost about 7% total body weight. However, it is still in clinical trials, has been around a while, and its implant nature is a drawback — like taking a drug that eventually has to come out, maybe a year later.
Several groups are doing hyperspectral imaging in surgery, including one in Lund doing phenomenal work. Using many narrow bands of wavelengths, each tissue has a fingerprint that can be identified, allowing surgeons to see margins of tumors without giving a dye. Dye injection is still used for lymph node testing, and LEDs in different kinds of cameras are what enable the hyperspectral light technology.
In esophageal tunneling procedures, blood vessels are hard to see, but AI can see them through pattern recognition and color them so the surgeon doesn't hit them, reducing the chance of vascular injury.
