We create more than a hundred new videos every year. They are the culmination of countless hours of research. We comb through tens of thousands of scientific papers from the peer-reviewed medical literature so busy people like you don’t have to.
In 2025, I covered a wide variety of hot topics. I released an extensive series on Ozempic, updates on vitamin B12, and, of course, a lot on aging and anti-aging based on my research for How Not to Age. Which videos floated to the top last year?

Pawpaw fruits, like soursop, guanabana, sweetsop, sugar apple, cherimoya, and custard apple, contain neurotoxins that may cause a neurodegenerative disease.
#2 The Highest Antioxidant: Apple, Bean, Berry, Lentil, or Nut?
Remember these kinds of videos from way back when? I brought them back! Of course, the best apple, bean, berry, lentil, and nut are the ones you’ll eat the most of, but if you don’t have a strong preference, which ones have the highest antioxidant power?
#1 How to Slow Cancer Growth
The fact that this video was so popular is validation for my plan to take on cancer after How Not to Hurt, my upcoming book on lifestyle approaches to pain management, which should be out in (fingers crossed) December 2026. This video explains how, at this very moment, many of us have tumors growing inside our bodies, so we cannot wait to start eating and living more healthfully.
