It would be helpful is you point to the scientific research supporting your bold claims. I'm aware there are competing thoughts, but I'd like to keep the conversation focused on science, not anecdotes or opinions. Harvard scientists are not infallable, but this is solid, peer-reviewed research that confirms findings by other studies at other institutions, and which is echoed by the CDC, WHO and other major health organizations. It deserves consideration, not summary dismissal. And yes, you are correct that excess sugar and empty carbs contribute to diabetes and poor health overall. There is no single culprit here, and no single food that will serve as a silver-bullet solution.
