The China Study

The China Study has genuinely influenced how millions of people think about food, and Campbell's underlying dataset is real and large — those are not small things. But the methodological criticisms are also real and well-documented: data selection, correlation-causation conflation, and omitted contradictory findings are not fringe complaints, they come from credentialed nutrition researchers. Read it as a thought-provoking starting point if you're curious about plant-based eating, but verify its claims against current nutrition science before making major dietary decisions.
