So far, research has yielded conflicting results about the effects of high-fructose corn syrup. For example, various early studies showed an association between increased consumption of sweetened beverages (many of which contained high-fructose corn syrup) and obesity. But recent research — some of which is supported by the beverage industry suggests that high-fructose corn syrup isn't intrinsically less healthy than other sweeteners, nor is it the root cause of obesity.

While research continues, moderation remains important. Many beverages and other processed foods made with high-fructose corn syrup and other sweeteners are high in calories and low in nutritional value. Regularly including these products in your diet has the potential to promote obesity which, in turn, promotes conditions such as type 2 diabetes, high blood pressure and coronary artery disease.
