White bread breakfast ups heart risk:

A study from the University of Sydney in Australia suggests that having a breakfast of white bread and sugar-rich cereals may make a person susceptible to diabetes, heart disease, and even cancer. University scientists evaluated 37 diet studies that involved nearly two million people across the world, and analysed the effect of eating foods with high glycemic index (GI), a measure of how different foods affect blood glucose levels. Their study, published in the American Journal of Clinical Nutrition, suggested that a high GI diet increased the risk of type 2 diabetes and heart disease. The researchers also said that a high GI diet was also seemed to be linked to gall stones and some types of cancer.
