GI Diet

Kellogg’s won’t be too happy to hear about this study: it suggests that a diet rich in carbohydrates that boost blood sugar levels, such as cornflakes or white bread, may hamper the function of blood vessels, therefore raising your risk of developing cardiovascular disease.

Researchers from Israel’s Chaim Sheba Medical Center and elsewhere evaluated 56 overweight or obese men and women, between 35 and 60. Other than their weight, they were healthy. None of them had diabetes or a history of cardiovascular disease.

They were fed foods that spanned the scale of the glycemic index, which relates to how a food affects your blood sugar levels. The higher the food is in the index, the more your blood sugar is spiked.
