Nutrition Science
Evidence-based nutrition science. How food becomes fuel: bioavailability, the gut microbiome, fiber, omega-3s, and more.
Nutrition science has a credibility problem. The same study gets reported as “coffee causes cancer” one week and “coffee prevents cancer” the next. That’s not because nutrition is unknowable. It’s because complexity doesn’t sell.
These articles present what the current evidence actually shows. We cite primary sources. We distinguish between strong evidence and emerging findings. And we explain the mechanisms, not just the conclusions.
