“There is always uncertainty in science, but real science gradually establishes some stable facts; it eventually strongly supports some theories and conclusively dismisses others. … Nutrition has made no progress. It has discovered no stable facts. Everything nutritionists have said, they have said the opposite ten or twenty years later (if not much sooner). They literally know nothing. After a century of countless experiments, the most common, most basic problem they’ve addressed—the optimal ratio of fat, protein, and carbohydrate—is completely unsolved. If they can’t figure that out, anything more sophisticated seems hopeless. … My point is not that nutrition is bad science. Unquestionably, it is bad science; a competent statistician, looking at the design of most experiments, will immediately say “this is meaningless; you can’t learn anything this way.” It’s worse than just incompetence … even the best studies have been useless. There seems to be something fundamentally wrong, such that doing the same sort of science better wouldn’t help.” https://metarationality.com/nutrition https://metarationality.com/nutrition
