Sugar is not necessarily the enemy. From what I have read, the body has a sort of "switch" that says "OK, enough" when you eat sugar. I recall when I was a kid, drinking those 6.5 oz Cokes. On the extremely rare occasion I got the chance to drink more than one, I would start to feel nauseous about half way through the third one. They contained sugar in those days. Now all soft drinks, store-bought cookies, snack crackers, processed foods, etc. contain high fructose corn syrup. A cheap sugar substitute. There is no "off switch" or "tank full" indicator for that. If you do a web search for high fructose corn syrup and obesity there are literally hundreds of articles from reputable sources that link the two. Of course HFCS cannot bear all the blame, but in my opinion there seems to be plenty of evidence to keep me away from it.
