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.

The glycemic index is an effective way of evaluating your eating habits. The GI refers to how a particular food’s carbohydrate affects your blood sugar level. This will not only have a say in your weight, but your energy levels and, proponents will say, your susceptibility to certain diseases.
A new study reaffirms the disease risk.
The study, conducted by Dr. David S. Ludwig and his colleagues from Children’s Hospital Boston, asserts that people who eat lots of high GI foods not only risk weight gain, they also run the risk of developing a condition that can lead to liver failure and death. The condition is known as non-alcoholic fatty liver disease (NAFLD).
If you are new to the GI way of thinking, high-GI foods include white bread, white rice and potatoes. Low-GI foods include most fruits, lentils, soybeans, yogurt and many high-fiber grains.
