Can Exercise Really Prevent Cancer? What 1.44 Million People Taught Us

📖 DescriptionIn this emotional and research-packed episode, Vic reflects on the rising number of friends and loved ones facing cancer—and what science says we can do about it.At the heart of today’s conversation is a 2016 landmark study published in JAMA Internal Medicine that analyzed data from 1.44 million adults to examine the association between leisure-time physical activity and the risk of developing 26 types of cancer.You’ll learn:🧬 The specific cancers most reduced by physical activity (some by over 40%)🏃 Why even 10–15 minutes of movement a day shows benefits☀️ Why melanoma and prostate cancer were exceptions💪 How exercise helps muscles compete with tumors for glucose🍽️ The role of fasting and protein moderation, based on Dr. Valter Longo’s researchVic also shares personal reflections on his vegan-to-Mediterranean diet journey, and his minimalist approach to supplements—only creatine and iron when necessary.Melanoma ↑ 27% (more sun exposure during outdoor activity)Prostate ↑ 5% (likely due to more frequent screening in active men)📚 Featured BookThe Longevity Diet by Dr. Valter LongoA science-based guide to optimal aging and disease prevention, including protocols like the Fasting Mimicking Diet (FMD). Longo's framework blends basic science, clinical trials, centenarian studies, and evolutionary biology to support dietary strategies that reduce cancer risk and promote long-term health.🔬 Key Research Studies & ResourcesJAMA Internal Medicine (2016)Association of Leisure-Time Physical Activity With Risk of 26 Types of Cancer🔻 Cancers with Lower Risk(% = relative risk reduction in the most active vs. least active group)Esophageal adenocarcinoma ↓ 42%Liver ↓ 27%Lung ↓ 26% (even in smokers)Kidney ↓ 23%Gastric cardia (upper stomach) ↓ 22%Endometrial ↓ 21%Myeloid leukemia ↓ 20%Myeloma ↓ 17%Colon ↓ 16%Head & neck ↓ 15%Rectal ↓ 13%Bladder ↓ 13%Breast ↓ 10%⚠️ Increased Risk (Likely Due to Detection or Exposure)Melanoma ↑ 27% (more sun exposure during outdoor activity)Prostate ↑ 5% (likely due to more frequent screening in active men)📄 Read the studyBreast Cancer & Exercise RecurrenceHolmes et al.
