Top 10 NutritionFacts.org Videos of 2025

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?

#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?
