I’m Type 1 & eat very low carb. The ADA guidelines still stress a diet that’s too high in carbs for most diabetics to control BG. Because they advocate higher carbs, they correspondingly tout A1cs that are higher than they should be:) Dieticians, nutritionists & most doctors also recommend diets that are too high carb for diabetics. So, we all have gotten the same message over & over until it’s been accepted as fact.
High carb diets have been linked to unhealthy lipid profiles for diabetics & non-diabetics. The high carb/low fat diet appears to be wrong. We could live long healthy lives without ever eating grains, starchy vegetables, beans.
Glycemic Index research hasn’t included diabetics, from the research I’ve seen. My experience has been that high GI or low GI have the pretty much the same effect on my BG. I just stick to low carb for better results.
