According to http://sweetsurprise.com/hfcsquickfacts.php  these are the facts about High Fructose Corn Syrup: 

• The American Medical Association (AMA) recently concluded that “high fructose corn syrup does not appear to contribute to obesity more than other caloric sweeteners.”
• Research confirms that high fructose corn syrup is safe and no different from other common sweeteners like table sugar and honey. All three sweeteners are nutritionally the same.
• High fructose corn syrup has the same number of calories as table sugar and is equal in sweetness. It contains no artificial or synthetic ingredients.
• The U.S. Food and Drug Administration granted high fructose corn syrup “Generally Recognized as Safe” status for use in food, and reaffirmed that ruling in 1996 after thorough review.
• High fructose corn syrup offers numerous benefits. It keeps food fresh, enhances fruit and spice flavors, retains moisture in bran cereals, helps keep breakfast and energy bars moist, maintains consistent flavors in beverages and keeps ingredients evenly dispersed in condiments. 

  So why have we made a huge deal about HFCS and how bad it is for us???  maybe one reason could be for the simple fact that as Americans we tend to over eat.  so, of course HFCS in large quantities is not good for the body.
