According to the study by University of Guelph researchers, blood sugar levels in people who ate low-sugar cereal were 250 per cent higher if they drank caffeinated coffee before or with breakfast, compared to decaf.So now I know what I have been doing wrong. I tend to have two large cups of cappuccino in the morning -one before and one after eating breakfast. And although I like the eggs and bacon, the lack of good back bacon (why is that?) and the fuss and mess often means I go for something easier - often oatmeal or an oat based cereal. Or, like this morning, a bagel.
Earlier research has shown that, "whether you're a healthy individual, obese or a Type 2 diabetic, when you ingest caffeine and then follow that with some food that's carbohydrate-based, for a prolonged period of time -- certainly six hours at least -- your body becomes insulin resistant," says Terry Graham, professor of human health and nutritional sciences at the University of Guelph.
There are some good decaf beans out there - I have some - but I have never been clear why caffeine is so demonised. It had seemed to me to be one of those knee jerk responses that you are always told to stop drinking alcohol, and caffeine, no matter what the condition. And people still go on about foods being "high in cholesterol" when all that I have read demonstrates that you make your own cholesterol and it is fat - and type of fat too - that actually matters.
And also I have learned that an espresso has less caffeine that a regular filter ("brewed") coffee, as the ground beans are on contact with the water for a lot shorter period of time.
