A bold claim. But is it evidence-based? Is sugar the "magic bullet" that will end diabetes if it is banned? Didn't we see that same argument made about banning trans fats? Trans fat bans did nothing of the kind, diabetes went up in New York City and now we are told all those crazy claims by food activists about saturated fats, like when bacon was the magic bullet thing to get rid of, were just pork-funded hyperbole.
It's an easy narrative, and vilifying sugar gives us a welcome break from claims that artificial sweeteners cause diabetes, but the study lacks scientific teeth.
