High blood sugar and high insulin is what brings on all those long term complications like, blindness, heart trouble, high
blood pressure and so on. Legumes are on the
list of good carbs. But one dry cup Black or Garbanzo beans would raise my Blood Sugar over 600 mg/dl. Add that to the steady state and no doubt it would be about 700 mg/dl. Actually no one would eat a cup of what had been a dry cup so the actual rise in b/g would be less. But substantial.
