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.
A BMJ study of all 1,712 former NFL players who died between 2008 and 2021 put the true rate of CTE at death somewhere between 24.5% and 97.7% for the most recent six years, a range wide enough to show how little the headline 93% figure actually settles.
Cochrane's updated living review of 80 trials and 29,861 people gives high-certainty evidence that nicotine e-cigarettes help more adult smokers quit than patches or gum, with serious side effects rare in every group.
A new National Bureau of Economic Research working paper found soda purchases dropped about 12% among SNAP households in 10 states with new restrictions, but recipients shifted up to 39% of that money into juice and other sugary drinks the rules do not cover.
A UK Biobank study of 46,448 people born around the end of British sugar rationing found lower rates of adult anxiety and depression in those restricted the longest, but the design cannot separate sugar from everything else that changed in 1953.
A Columbia team mapped nearly half a million cells from donated human hippocampus tissue and found that in major depressive disorder, new neurons start forming but fail to mature.
A 376,511-person Swedish cohort found that people who returned their mailed stool kit had 43% lower colorectal cancer mortality, while everyone who was merely invited had 26% lower mortality, and the difference between those two numbers is behavior, not biology.
What if cancer is better understood as a metabolic and mitochondrial disease than a purely genetic one? Dr. Ravi Kumar sits down with Dr. Casey Peavler, a hospitalist who has spent years digging into the metabolic science of cancer, to walk through the press pulse framework: a chronic press like therapeutic ketogenic metabolic therapy and stress reduction that handicaps a tumor's fuel supply, followed by intermittent pulses like high dose IV vitamin C and hyperbaric oxygen delivered when the cancer cell is least able to defend itself. They cover why glucose and glutamine supply roughly 80% of the NADPH a cell uses for antioxidant defense, why antioxidants may help prevent cancer but appear to worsen outcomes once it is present, and how repurposed drugs like metformin, mebendazole, and ivermectin fit in. Nothing here is medical advice, and every therapy discussed is framed as a potential add-on to work through with your oncologist.

Dr. Ravi Kumar is a board-certified neurosurgeon and assistant professor of neurosurgery at the University of North Carolina. After years in the operating room, a transformative sabbatical in India changed how he saw medicine forever.
Now, through The Dr. Kumar Discovery, he explores the intersection of modern science, traditional wisdom, and the questions most doctors never think to ask.
