I think my point was lost a bit from the discussion of potatoes. I was just suggesting you keep careful notes on what you have eaten and correlate it with your blood sugar tests for several weeks. Soon you will realize what sends your blood sugar higher and what does not. This is theoretically captured in the glycemic load, but I have found personally that some of those guidelines don't always work for me but do give a clue.
A couple of notes: Per the Harvard glycemic load index, a boiled medium white potato has about 22 glycemic points, a baked medium sweet potato has about 21. An average serving of rice has over 70. I have found no difference in my response to brown rice or white rice. Some probably do.
Cook books I have found to provide really yummy dishes that my friends and family love also are:
Better Homes and Gardens Diabetic Living Slow Cooker Recipes, and the Betty Crocker cookbooks for diabetics. They really seem to work too in my journal tracking. I use Perfect Diet Tracker on my computer, that costs around $30 to keep track of my food, weight, and blood sugar. It's simple and works well. There are probably others out there.
Today I am cooking one of the stews in my slow cooker from the BH&G cookbook.
It's an adventure that can be fun.
