One of the most common questions centers on data and verification. Here are a few resources to check out. Due your own due diligence before acting.
Tier 1. Research translators. Highest signal-to-noise.
- Nutrition Made Simple! (Gil Carvalho, MD PhD) — https://www.youtube.com/@NutritionMadeSimple
- Reads the actual literature, states effect sizes, says "we don't know" out loud. Best model of scientific reasoning on YouTube.
- FoundMyFitness (Rhonda Patrick, PhD) — https://www.youtube.com/@FoundMyFitness | https://www.foundmyfitness.com
- Deep mechanism work. Long-form expert interviews. Note: she is more willing to extrapolate from mechanism than Carvalho.
- The Peter Attia Drive — https://peterattiamd.com/podcast | https://www.youtube.com/@PeterAttiaMD
- Longest-form clinical reasoning available in public media. Lipidology, cancer screening, exercise physiology.
- Physionic (Nicolas Verhoeven, PhD) — https://www.youtube.com/@Physionic
- Study-by-study breakdowns with explicit methodology critique.
- Sigma Nutrition Radio (Danny Lennon) — https://sigmanutrition.com
- Academic nutrition science. Low production value, high accuracy.
- Ground Truths (Eric Topol, MD) — https://erictopol.substack.com
- Cardiologist, one of the most-cited researchers in medicine. Sharp on hype detection.
Tier 2. Strong practitioner-scientists. Domain-specific.
Tier 3. Popular and useful. Verify before acting.
- Dr. Joel Kahn — https://drjoelkahn.com
- Preventive cardiology, plant-based. Real credentials. Advocacy position, so the evidence gets presented one-directionally.
- The Dr. Hyman Show (Mark Hyman, MD) — https://drhyman.com
- Wide reach, good guests. Functional medicine framing, heavy supplement commerce, frequent claims that outrun the data. Treat as a topic discovery tool, not a source of truth.
Tier 4. Verification tools. Where you go to check the above.
Rule for use: the tier tells you how much verification a claim needs before you act on it. It does not tell you who is smart. Everyone above is smart. They differ in how far past the data they are willing to walk.
