Harvard Historian of Science Steven Shapin on the Nutrition Wars
Last month the US government issued a 571-page report suggesting it would be making significant changes to its dietary guidelines. Eggs are no longer a no-no. Caffeine consumption is encouraged to prevent Parkinson’s disease. The report comes at a time when new studies, and journalists including Gary Taubes, Nina Teicholz, and Aaron Carroll, have called into question the low-fat, high-carbohydrate diet promoted by the nutrition establishment for more than half a century.
Breakthrough is interested in the battle over dietary advice as an example of “wicked problem” — a problem characterized by high levels of uncertainty and expert disagreement — and asked Harvard historian of science, Steven Shapin, to provide some historical and sociological context. Shapin is the author of numerous articles and books about the history diet and nutrition.
