Check out the recent SNL parody of the High Fructose Corn Syrup t.v. advertisement.
We think Michael Pollan got it right in Food Rules in suggesting we avoid products with HFCS:
Not because high-fructose corn syrup (HFCS) is any worse for you than sugar, but because it is, like many of the other unfamiliar ingredients in packaged foods, a reliable marker for a food product that has been highly processed. Also, high-fructose corn syrup is being added to hundreds of foods that have not traditionally been sweetened – breads, condiments, and many snack foods – so if you avoid products that contain it, you will cut down on your sugar intake.
