Gary Taubes on demonizing saturated fat and the diet-heart hypothesis: warns against

Gary Taubes warns that the idea that saturated fat causes heart disease was never rigorously established, and that the cholesterol-focused framework — making LDL the “bad cholesterol” — oversimplified the science in a way that salvaged decades of research. He develops this argument in Good Calories, Bad Calories and has continued it in his 2026 Substack writing, including the post “Bad Health Journalism, an addendum.”

His stated reasoning: he argues that the diet-heart hypothesis became institutional doctrine before the clinical-trial evidence for it was in, and that subsequent generations of researchers kept patching the framework (elevating LDL as the villain) rather than re-examining the foundations. In his telling, an entire regulatory and medical edifice was built on an untested assumption.

Criticism worth noting: mainstream cardiology organizations continue to hold that reducing saturated-fat intake lowers LDL cholesterol and cardiovascular risk, and this remains one of the most contested claims Taubes makes.
