The Silent Toxin Buildup That Ages Your Brain | Dr. Anne Marie Fine (opens the original)
Read excerpt
Today we're getting into something most of us never stop to think about: the chemicals we're all swimming in every day, and whether they're quietly aging our brains faster than our genes ever could. In a UK Biobank study of blood plasma proteins, people with youthful brains looked like they carried two protective copies of APOE2, the good version of the Alzheimer's gene, and people with aged brains looked like APOE4 carriers, the highest risk version, regardless of what genotype they actually ha
A Yoga Expert and a Spine Surgeon Agree on the One Exercise Everyone Needs | Dean Pohlman (opens the original)
Read excerpt
If sitting all day has left your back stiff, your glutes asleep, and your shoulders rounding forward, the tool behind this episode, Man Flow Yoga, is built to fix exactly that. Dean Pohlman's app has over 50 structured programs running from five to sixty minutes, and you can grab a discount with code Kumar. Most guys picture yoga as a stretching class for people who are already flexible, something to skip if you already lift or run. But a 2017 study found yoga is just as effective as physical th
The Science of APOE4: Why Evolution Kept the Alzheimer's Gene (opens the original)
Read excerpt
Every year more people get their DNA tested, and a lot of them find out they carry a gene called APOE4, the so called Alzheimer's gene. Today Dr. Ravi Kumar takes it apart, because he carries a copy himself, and the standard story about it never quite added up to him. Ravi builds the case with real data. In the Tsimane of the Bolivian Amazon, a 2017 study of 372 people found something backwards from what you'd expect: APOE4 carriers with a heavy parasite burden held onto their cognition while no

If you're new here, do me a favor and hit subscribe, and if this episode gives you something to chew on, a quick review helps more people find the show. Today's conversation is one of the most eye-opening we've done on the link between diet and severe mental illness. Here's a claim that sounds almost too big to believe: in a small pilot trial at Stanford, everyone with schizophrenia or bipolar disorder who stayed fully adherent to a ketogenic diet went into remission from their mental health dis
The Cancer Add-On Therapies Most Oncologists Never Mention | Dr. Casey Peavler (opens the original)
Read excerpt
What if cancer is better understood as a metabolic and mitochondrial disease than a purely genetic one? In this episode, Dr. Ravi Kumar talks with a hospitalist who has spent years digging into the metabolic science of cancer about the idea that mitochondrial dysfunction may actually come first, as a precursor to the genetic abnormalities we associate with tumors, and what that reframing opens up for patients already in treatment. Doctor Peavler is a hospitalist by day who began offering integra
