What do you think of the commercial products with high fructose corn syrup?

HFCS. Don't eat them. There are masny healthy, natural sweeteners on the market. Refined corn syrup is just as dangerous as white sugar.
Stay away. Hfcs is just plain bad for you. If you can stay away from it, you will likely be better off from a health standpoint. There isn't enough room here to go into details...Google - joseph mercola md, he has plenty to say on it.
