I found it extremely difficult to give up my breakfast toast and then I read that multi grain, seeded bread or rye bread has less effect on your blood sugar. I have found this to be true for me. I have two VERY thin slices, toasted from frozen. I slice it extremely thinly - about 0.5cm - on a bread slicer before freezing. I do test from time to time after eating this and find it only has a small, acceptable, effect on my blood sugar. But you need to try it and test yourself. Toast doesn’t really affect me but mashed potato - wow!
