Limiting fructose or HFCS in the diet would not have an impact on global obesity. Food formulators would simply reformulate products by substituting alternate sweeteners, many of which contain fructose as one of their components. Further, obesity is a global phenomenon while HFCS is primarily used in the United States. Obesity rates in Europe and South America are high whereas these areas do not use HFCS as a sweetening agent for food and beverages.
