"This is how functioning science works. Outstanding questions are identified or hypotheses proposed; experimental tests are then established either to answer the questions or to refute the hypotheses, regardless of how obviously true they might appear to be. If assertions are made without the empirical evidence to defend them, they are vigorously rebuked…. Each new claim to knowledge, therefore, has to be picked apart and appraised…. This institutionalized vigilance, “this unending exchange of critical judgment,” is nowhere to be found in the study of nutrition, chronic disease, and obesity, and it hasn’t been for decades."
