Too much sugar is not good for health. According to a study at Saint Luke's Mid America Heart Institute says that maybe this food has a greater impact on coronary heart disease than saturated fat. This was published in the journal Progress in Cardiovascular Diseases. Another study from Queen Mary University of London says that High maternal sugar intake during pregnancy may increase the risk of allergy and allergic asthma in the offspring. The European Respiratory Journal published this study. These and many other similar studies say the same thing. Sugar is bad for you. It is not entirely true.
