Jeff Nelson — VegSource

Investigations into health and nutrition. Real questions, real research, no agenda.

For three decades I've run Vegsource — one of the longest-running plant-based health resources online and the home of Dr. John McDougall's talks, which remain as relevant and accurate today as they were when he gave them decades ago. The channel covers what the science actually says about food, supplements, disease prevention, and the gap between what gets sold to us and what holds up over time.

Plant-based, evidence-based, and unafraid to revisit what the mainstream got wrong.

I'm also Jeff Nelson, the author of Fault Lines, The Montecito Rules, and the upcoming Jackie Kennedy's Stylist (June 18, 2026) and Lights, Camera, Roma (July 1, 2026).

For my memoir series about growing up inside one of America's great old-money families, see link below to Jeff Nelson Stories — separate channel, separate kind of show.
