Eating low-sugar cereal may seem like the healthy choice, but drink a cup of coffee before breakfast and you might as well go for the chocolate corn pops.
Canadian researchers say drinking coffee before eating your morning cereal can affect the body's blood-sugar response and cause blood glucose levels to rise dramatically - especially when eating low-sugar cereals.
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.
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.
