“So, we’ve known for at least 30 years, 60 years by the looks of that 1955 Lancet study, that low-fat diets could arrest the symptoms of diabetes or prevent the disease altogether.
Robbins’ “Diet For A New America” was a popular lay-person’s book (1st edition sold over a million copies), not a medical tome. It was in the social realm. Why isn’t its low-fat advice common knowledge? I’ll tell you … It’s for reasons that induce stores like Natural Grocers to ban Dr. Greger’s plant-based book. It’s because having people eat a low-fat, high-fiber diet would hurt sales of animal food: beef, pork, chicken, fish, eggs, and all manner of dairy food – cheese, yogurt, milk, butter, cream. That’s why. And you know how the meat and dairy industries keep a lid on the science that could really help people? They come out with their own studies, often meta-analyses which go back in time and cherry pick studies that defend their position.”

One of the references Robbins uses to support his contention is a 1979 article in American Journal of Clinical Nutrition. It’s a study of 20 men, all of whom were on insulin for what I assume is type 2 diabetes. What’s odd is that the men were all “lean.” In real life, at least 85% of type 2 diabetics are overweight or obese. Not lean. Nevertheless, many of the men were able to stop insulin on the low-fat/high fiber diet. But these weren’t typical T2 diabetics.
