I agree that the Glycemic Index and Glycemic Load are very important. You could eat the same amount of carbs using high GI and GL foods and get an up in blood sugar, or eat low ones and be fine.

I may not be able to tolerate things like Barely or whole grains ever, as I'm type 11 Diabetic, but some people may do just fine.

I think everyone has to find what works for them. Oh, and I too have found that it's not just WHAT I eat, it's also what I eat WITH it.

And the time of day makes a difference too.

Very interesting to look at the GI and GL-explains why a few berries are okay, while the equal amount of carbs in, say, a banana wouldn't work.

And if your system hasn't been messed up by yo yo dieting, or being addicted to the carbs in a way that has damaged your metabolism, it does make a difference. To each their own
