Like "Certainly Katherine, Here is what I do: What I do is to take a BG reading before I test a food. That is my baseline reading. I determine what a "serving" of a particular food is using either ( or nutrition ( or ( ) eat a recommended portion of that food. Then 2 hrs lafter my first bite I take a "postpramdial" reading. That will tell me how much that particular portion of food has raised my BG levels over my baseline readings. If it raises my BG less than 50 pts, I may eat that portion without much trouble. If it raises my BG over 50 then I need decide whether it is too much over 50 or not and I may want to retest it with a lower portion size. If it is closer to a 100 pts raise then I usually decide to avoid that food altogether. I then put a page in my 3 ring binder with that food on it, and record the baseline, the portion conumed and the postprandial results, and my decisions made, whether to retest with a lower portion, and then results of that test, or if I decided to avoid that food altogether. I do that so I remember what I've tested and what my decisions were, so I don't have to test again needlessly. That way I have a book of what works for ME and my metabllism specifically. It may seem to be a lot of testing, and perhaps it is. But I have found it is worth the cost for me in keeping my BGs under better control. Knowing is better than just guessing. I pray that this is useful for you! Blessings James"
