As I have previously mentioned, I am a type II diabetic, as well as a Perfect Health Diet adherent. I have been following the PHD quite rigorously for a while now and wanted to report on the progress.
First, I eat safe starches every day as part of my Paleo diet. Usually a half a cup of rice or a small- to medium-sized baked potato. Lately, I have been eating sweet potatoes (small to medium sized) most every evening, without anything added. And I check my blood sugar regularly. Two hours after eating a dinner of baked salmon with lemon infused olive oil, salad, balsamic vinegar, olive oil, and a medium sized sweet potato, my blood sugar was 95. My fasting blood sugar was 101 the next morning (my morning readings have always been high; Jenny Ruhl calls this the "dawn phenomenon"). Now these are not "normal" readings, but they are very good for me, especially given my history.
What is interesting is that my blood glucose levels have consistently fallen since adding in safe starches (and following the other aspects of the Perfect Health Diet), especially my fasting blood glucose readings. So I still reject the safe starch exclusion for type II diabetics. If it helps, like it does for me, eat safe starches, even if you are a type II diabetic.
