Does sugar cause health illnesses?
Sugar does not cause heart disease, cancer, diabetes or obesity. People gain weight when they consume more calories than they expend. Sugar does provide calories (4 per gram), but other digestible carbohydrates (like starch) and protein provide the same amount. And, you should know that other caloric sources, namely fat and alcohol, provide many more calories per gram than sugar does: alcohol provides 7 calories per gram, and fat provides more than twice as many as sugar (9 calories per gram). Sugar is the main source of calories in regular (non-diet) soft drinks.
