Episode 464: Is Lead in Protein Powders a Major Concern for You?

This week, Dr. Kahn dives into new research linking plant-based diets to both a lower risk of type 2 diabetes and improved control in type 1 diabetes. (Fun fact: even eating one juicy mango a day can help with blood sugar control!) He also tackles the recent Consumer Reports headlines about lead in protein powders, explaining why the use of California’s Prop 65 limits may have exaggerated the concern compared to what most health experts believe.  Finally, Dr. Kahn reviews new data on Lipoprotein(a) and heart health—including one fascinating study that connects risk levels to waist size.  This episode is brought to you by the Fresh Pressed Olive Oil Club.

Dr. Kahn also breaks down two emerging treatments gaining popularity—EBOO (Extracorporeal Blood Oxygenation and Ozonation) and TPE (Therapeutic Plasma Exchange)—and how they may play a role in improving cardiovascular health. In the second half, Dr. Kahn turns to the topic of cholesterol-lowering therapies like statins, emphasizing how long-term use and individualized risk assessment matter more than online debates suggest. He highlights tools such as the Mayo Clinic Statin Decision Aid, PREVENT calculator, and Astro-CHARM calculator to help patients and practitioners make informed decisions.  Thanks to the Fresh Pressed Olive Oil Club for sponsoring this episode.

Plus, hear how maintaining low cholesterol and heart-healthy habits starting at age 18 can dramatically improve long-term outcomes.  A packed episode filled with practical takeaways for your heart and overall health.

Connie Zack, co-founder of Sunlighten Sauna, joins Dr. Kahn to discuss the science and benefits behind infrared sauna and red light therapy. Sunlighten is the leading brand in “full spectrum” infrared saunas, designed to deliver maximum results even at lower temperatures. Connie explains how infrared sauna therapy can improve cardiovascular health and support healthy blood pressure—benefits that are well documented in clinical studies. She also explores the growing field of red light therapy (photobiomodulation), which offers additional wellness advantages and even includes FDA-approved applications.  This episode dives into how combining these two therapies can optimize overall health and recovery. You’ll enjoy this insightful and practical conversation.

This week marks the 10th anniversary of the Kahn Center for Cardiac Longevity—thank you for being part of the journey! Dr. Kahn reviews important new Mayo Clinic data comparing causes of heart attacks in men vs. women under 65. The findings show that non-traditional causes are significantly more common in women. Because the study ended in 2018, neither COVID nor vaccine-related data were included. In addition, Dr. Kahn covers a range of timely health topics: Sucralose (Splenda) and cancer therapy Magnesium for hypertension Eating early vs. late in the day Hydration and survival The ongoing debate over whether meat promotes or protects against cancer deaths (spoiler: it does not) Thanks to Igennus.com—use discount code DrKahn for savings.

Dr. Monica Aggarwal, a practicing cardiologist and mother, experienced rheumatoid arthritis but was able to dicontinue using medications through the diet and lifestyle changes as she shares in her book Body on Fire. She later completed a randomized study of plant-based diets—with and without olive oil—showing that both improve outcomes compared to the standard American diet. An advocate for whole foods, she suggests choosing avocados and olives over the oils derived from them, while also recognizing supporting data for extra-virgin olive oil and avocado oil. Check out her book and listen to our conversation on this special bonus episode of Heart Doc VIP with Dr. Joel Kahn.

This week, Dr. Joel Kahn dives into surprising results from recent medical research. The most eye-opening? Women recovering from a heart attack with relatively preserved heart function were found to have higher mortality risk when discharged on beta-blockers — a finding that challenges 40 years of clinical practice. Dr. Kahn urges listeners to discuss these results with their own healthcare teams. Other unexpected studies are highlighted too, including new insights on taurine, spermidine, meal timing, ketogenic diets, aspirin therapy, and even sugar substitutes.  Special thanks to igennus.com — use discount code DrKahn for savings.
