The title is catchy and leads you to believe you can “prevent” diabetes with diet. I personally favor the concept of delaying diabetes rather than preventing the disease. My father (deceased) had, and my youngest brother has diabetes. I knew what my risk was and continues to be.
Many years ago I asked one of the country’s top endocrinologists what I could do to avoid developing diabetes. His answer was short and simple:
Stay as thin as you can as long as you can.
Be nice to your pancreas!
