Dr. Ravi Kumar is a board-certified neurosurgeon who left the operating room to explore the questions that matter most about your health.
Listen to the PodcastEvery week, I cut through the noise of health headlines and marketing claims to bring you what the research actually says. No dogma, no agenda, just an honest look at the science that shapes how you live, heal, and thrive.
In 56,964 UK adults, brisk activity and less ultra-processed food were tied to lower type 2 diabetes risk even when genes loaded the dice, so a family history is no reason to skip moving more and cutting sugary drinks, though the study cannot prove those changes cause the drop.
If you have chronic low back pain, a review of 239 exercise trials suggests three or four 25 to 30 minute sessions a week for two to three months helps about as much as doing more, but pain that runs down your leg was almost never studied and needs its own plan with your doctor.
A Maryland state lab found high lead in Lior Cinnamon Ground Seasoning sold in New York, New Jersey, Pennsylvania, Texas, Florida and Illinois; if lot GAP11304 is in your cabinet, stop using it and throw it out or return it.
A Cornell analysis of nearly 150,000 new US foods and drinks found that claims like "low sodium" and "no trans fat" can sit on products that make up for it with more sugar, salt or saturated fat, so the Nutrition Facts panel on the back is the part to read.
If you have type 2 diabetes and are offered a few days of steroid pills for back pain, a rash or a cough, a new Taiwan study is a reason to ask whether you need them and to watch for black stools, fever or shortness of breath over the next month.
No dementia vaccine exists yet, but 72% of Americans over 50 say they would take one, and the shingles shot, already linked to lower dementia risk, is something you can ask your doctor about today.
Dr. Anne Marie Fine is an environmental medicine physician who has spent 25 years measuring what the rest of medicine never tests for. She and Dr. Ravi Kumar get into a UK Biobank study of 44,000 people where the brain and immune system, not the heart, tracked hardest with aging, and where youthful brains behaved like APOE2 carriers and aged brains behaved like APOE4 carriers no matter what the genotype actually was. They work through cadmium, lead released from bone during menopause, mercury vapor from dental fillings, PFAS blunting vaccine antibody response, benzene left behind by a gas stove, mold toxins that shut down glutathione production, DDE that 99% of Americans still carry, and gadolinium from contrast MRI. Then they turn to what you can actually do: avoidance first, air and water filtration, cleaning up makeup and food packaging, and why testing yourself broadly without a plan is bad medicine.

He is the best of both worlds - he shares a wealth of modern medical knowledge, but also empowers the listeners to take personal responsibility for their health."
