read and learn. Lots of good books about it, and try the site "diabetes 101" . There is some controversy about diets, with differences of opinion about how much carb restriction to do, and what types of carbs are ok. Most of us here have found that testing before and after meals, a LOT for a while has taught us how we respond individually to different foods, so we know what to restrict and what works well for us. Certainly you will see that we are a diverse bunch. Good luck to you, and keep visiting and sharing with us!
