Episode 507: The Nuance of How Much Dietary Protein for Optimal Health

This week, Dr. Kahn discusses new data from the amazing Valter Longo, PhD, and his colleagues regarding optimizing diet for both longevity and strong muscles. In a new publication, Dr. Longo used mouse models to show that animals fed a Longevity Diet, as described in his book, lived longer. However, when moderate amounts of methionine, an amino acid, were included in the diet, frailty was avoided. He then analyzed a dataset of 200,000 health professionals in the United States and found that those consuming the highest amounts of animal protein had double the risk of type 2 diabetes, as well as higher rates of obesity and hypertension, compared with those consuming more plant protein. You can learn more about Dr. Longo's L-Protein powder (with methionine) at prolonlife.com/drkahn. Other topics include PCOS and heart disease, aortic dissection, artificial sweeteners and memory loss, optimal medical treatment for high cholesterol, GLP-1 agonist use and hair loss, TMAO and the risk of atrial fibrillation, statins and better cognitive function in women, and how plant mitochondria may improve our own cellular function.

In this bonus episode, Dr. Kahn interviews functional medicine specialist Ivan Rusilko about the importance of advanced lab panels. Together, they explore the full spectrum of cardiac lab testing, with a special focus on inflammation, insulin resistance, and how these markers can uncover hidden cardiovascular risk.

This week, Dr. Kahn discusses the FDA approval of the first oral PCSK9 inhibitor, Lipfendra (enclicitide), taken as a 20 mg daily tablet. In a study of nearly 3,000 patients with elevated LDL cholesterol despite treatment with statins and, in many cases, ezetimibe, LDL-C dropped by more than 50% while Lipoprotein(a) levels fell by 28%, with an excellent safety profile. The medication is expected to retail for approximately $315 per month and will be available in pharmacies soon. A larger outcomes trial evaluating its impact on heart attack and stroke rates is currently underway. Other topics include oatmeal for diabetes, avocados for cholesterol, ketogenic diets and cancer, serotonin and heart valve disease, air pollution and cardiovascular events, and the relationship between sweetened beverages, fruit juice, and high blood pressure. Dr. Kahn also mentions the air filtration system he uses at home and in his office, available at: airdoctorpro.com Finally, thanks to this week's sponsor, the Fresh Pressed Olive Oil Club.

This week, Dr. Joel Kahn explores important new research showing how elevated inflammation, measured by Interleukin-6 (IL-6), may dramatically increase cardiovascular risk in people with high Lipoprotein(a), or Lp(a). He explains why IL-6 is emerging as an important biomarker and reviews the other inflammation tests he routinely uses at the Kahn Center, including hs-CRP, MPO, Lp-PLA2, NT-proBNP, fibrinogen, ferritin, the sedimentation rate, and the white blood cell count. Dr. Kahn also discusses Lilly's newly approved oral weight loss medication, the ABCDEF framework for cardiovascular prevention, the growing evidence linking erectile dysfunction and sleep apnea to heart disease, new research on cannabis use and coronary artery plaque, and intriguing early findings on creatine's potential role in supporting the immune system and anti-tumor activity.

Dr. Joel Kahn explores the latest science on supplements that may help slow or reverse atherosclerosis, building on a recent discussion from Simon Hill's The Proof podcast. He takes a closer look at the evidence behind vitamin K2, niacin, pycnogenol with centella asiatica, beta-cyclodextrin, and bergamot, explaining where the research is strongest and what it could mean for heart health. Additional topics include new research on nutrient deficiencies to watch for in vegan diets, the potential kidney risks of certain calcium channel blockers, the health benefits of onions, advanced plaque measurements from coronary CT angiography, the connection between periodontal disease and kidney disease, and how fasting-mimicking diets may improve gum health. Dr. Kahn also reviews encouraging early results from an emerging Lipoprotein(a)-lowering therapy that could reduce the need for lipoprotein apheresis.  Dr. Kahn is leading a group PROLON fasting-mimicking diet beginning this Sunday, July 12, and continuing for five days. A PROLON kit is required and can be purchased at prolonlife.com/drkahn. The NextGen version is recommended.  Finally, a giant thanks to this week's sponsor, Igennus.

This week, Dr. Kahn reviews important new research showing that the commonly prescribed antidepressant Prozac (fluoxetine) may disrupt cholesterol metabolism, injure the endothelium (the delicate lining of arteries), and potentially increase cardiovascular risk. He also examines growing evidence linking proton pump inhibitors (PPIs) and several common cancer therapies to endothelial damage, emphasizing that patients should always discuss the risks and benefits of these medications with their healthcare team rather than stopping treatment on their own. Other topics include new Harvard research showing that combining aerobic exercise, strength training, and less time spent watching television can reduce the risk of type 2 diabetes by up to 60%; promising data on niacin for glioblastoma brain cancer; predicting statin-related muscle injury; the protective effects of plant-based diets against heart disease, dementia, and several cancers; tea consumption and lower cardiovascular risk; vitamin K-rich leafy greens and lung health; whole grains and breast cancer prevention; and the latest research on red meat, inflammatory bowel disease, and hypertension.  Thanks to igennus.com/drkahn for this week's podcast sponsorship featuring their vegan Super B Complex.

Can a simple gratitude practice improve your heart health? This week, Dr. Kahn explores the growing science linking gratitude to better well-being, improved sleep, lower inflammation, and even enhanced cardiac function. He shares his own gratitude practices and offers practical ways to incorporate them into daily life.  Also covered in this episode: how adherence to Life's Essential 8 is associated with longevity, even among the ultra-elderly; the importance of identifying cholesterol hyperabsorbers; the connection between obesity and cancer risk; the relationship between sleep apnea and Lipoprotein(a); why strength training is especially important for women; and the link between hypothyroidism and elevated homocysteine levels.  Thanks to IGENNUS for their support of this episode, featuring their vegan Pro-Collagen Powder.

In Episode 499, Dr. Joel Kahn explores the growing importance of apolipoprotein B (ApoB) testing as a powerful tool for assessing cardiovascular risk. He reviews new research highlighting why ApoB may provide a more complete picture of atherosclerosis risk than traditional cholesterol measurements alone and explains how it relates to LDL-C and Lp(a). Dr. Kahn also discusses several noteworthy studies in preventive medicine and longevity, including research linking GLP-1 medications to lower cancer risk, the potential DNA-protective effects of melatonin, and new findings on stroke and clot prevention in patients with atrial fibrillation. Additional topics include the relationship between very low Lp(a) levels and diabetes risk, the benefits of organic produce for breast cancer prevention, Pilates training for blood pressure management, and the connection between processed meat consumption and gastrointestinal cancers. The episode concludes with a look at Endothelin-1 (ET-1), an important marker involved in vascular health and cardiovascular disease, along with a discussion of Vinia grape powder and its potential role in lowering ET-1 levels.

Dr. Joel Kahn dives into a groundbreaking Phase 1 trial of Verve 102, a one-time intravenous gene-editing treatment that silences the PCSK9 gene to produce lasting LDL cholesterol reduction. Among 35 participants, the high-dose group saw LDL drop by 62% with mostly mild side effects — promising results, though Phase 2 and 3 trials and 15 years of follow-up still lie ahead. Also covered: updated colorectal cancer screening guidelines now starting at age 45, healthy lifestyle habits cutting mortality risk in cancer survivors by one-third, real-world weight regain data after stopping GLP-1 medications, why your B12 "normal" range may be too low, a blood test that may predict Alzheimer's years in advance, and a longevity preparedness tool from MIT AgeLab.
