I'm a type 1 since 1982, went on 'human insulin' Regulal and NPH. I quickly was on a 3,000 plus calorie diet. I never altered it besides moving two of my three snacks into meals. I consume about 60% carbohydrates, I do about 30% fat. So I consume fresh brewed Yerba Mate with oolong added. Both mild and high in thenine. I also take melatonin. My insulin use is low for by body weight. Interesting that not avoiding sugar could be ok with a balanced diet and actually help the insulin be less oxidative.
