Q. Is high-fructose corn syrup bad for you?

By Joyce Hendley, September/October 2007

Is high-fructose corn syrup bad for you?

A. High-fructose corn syrup (HFCS) is a manmade sweetener that’s found in a wide range of processed foods, from ketchup and cereals to crackers and salad dressings. It also sweetens just about all of the (regular) soda Americans drink. HFCS used in foods is between 50 to 55 percent fructose—so chemically, it’s virtually identical to table sugar (sucrose), which is 50 percent fructose. Metabolic studies suggest our bodies break down and use HFCS and sucrose the same way.

Yet, after HFCS began to be widely introduced into the food supply 30-odd years ago, obesity rates skyrocketed. And because the sweetener is so ubiquitous, many blame HFCS for playing a major role in our national obesity epidemic. As a result, some shoppers equate HFCS with “toxic waste” when they see it on a food label. But when it comes right down to it, a sugar is a sugar is a sugar. A can of soda contains around nine teaspoons of sugar in the form of HFCS—but, from a biochemical standpoint, drinking that soda is no worse for you than sipping home-brewed iced tea that you’ve doctored with nine teaspoons of table sugar or an equivalent amount of honey.

Even Barry Popkin, Ph.D., a nutrition professor at the University of North Carolina at Chapel Hill who previously suggested, in an influential 2004 paper, a possible HFCS-obesity link, stresses that the real obesity problem doesn’t lie just with HFCS. Rather, it’s the fact that sugars from all sources have become so prevalent in our food supply, especially in our beverages. He scoffs at the “natural” sweeteners sometimes added to upscale processed foods like organic crackers and salad dressings. “They all have the same caloric effects as sugar,” he explains. “I don’t care whether something contains concentrated fruit juice, brown sugar, honey or HFCS. The only better sweetener option is ‘none of the above.’”

At EatingWell, it’s our philosophy to keep any sweeteners we use in our recipes to a minimum—and likewise, to limit processed foods with added sugars of any type, including HFCS. We recommend you do the same.

Did you know?

The corn syrup found on supermarket shelves is only a distant cousin to the high-fructose corn syrup used commercially. Both start by processing corn starch with enzymes and/or acids, but the HFCS process is much more complex and results in a different chemical structure.

If you didn't lose weight by cutting out soft drinks... you probably weren't drinking any to began with. I stopped drinking american soda and started drinking mexico soda, which is made with real sugar by the way, and I have lost weight. I think there is something about the fructose sugar.... More research is needed than what this add is putting out.

Have you worked in a packing house where pigs are processed. Have you noticed the increase in size of pork chops and other pork cuts in the last 4 yrs? Have you noticed the sweet flavor in all pork lately?What exactly do you know about raising and feeding hogs?

While in the process of not drinking soda you gotta make sure you don't eat junk food either to lose weight. Anybody can speed their metabolism up.

I am wondering how you inject an entire pork carcass with corn syrup. And as far as letting a pig grow older and more valuable, that is pure ignorance. Pigs feed and gain weight to a certain age and then stop converting their feed as efficiently. So you have to feed more to get another pound of body weight, and the cost of the feed eats into your profit, I call BS on that post.

I've lost (and kept off for 2 years) 40 lbs just by cutting out HFCS......

When you stop drinking soda, you tend to lose weight because you have cut out all of the extra calories that are in soft drinks and those calories mainly come from the sugar in them. If you stopped eating sweet cereals, didn't drink sweet tea, didn't add sugar to your would have the same metabolic response. I have stopped drinking soft drinks for months and months, drinking nothing but water and didn't lose an it really depends on the person, their metabolism, daily physical activity and the other things they eat and drink on a daily basis.

Stevia is wonderful!! And yes, one does lose weight, avoiding diet pops and foods and drinks containing high fructose and corn syrup.
