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

By Joyce Hendley, M.S., 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.

What has not been mentioned here is that when HFCS is consumed, the calories consumed are not recognized by your body. That HAS BEEN PROVEN. It is put in foods so that people will just keep eating it without getting full. I get so angry when I see these commercials about it being no different than real sugar. It is seriously misleading. Of course it is not as good for you as NATURAL sweeteners like REAL sugar or honey. It is so cheap though and in EVERYTHING now that it is insane. I try to only buy things that don't have HFCS but it is very difficult to do which is just not right. I would prefer to pay more for quality food and I do. I don't really drink soda because I think it is terrible for you but when I do, I only drink the Pepsi that is made with real sugar (the original formula) when it is available.

a recent study with HFCS and rats shows that rats fed HFCS became stupider at negotiating a maze... just what the U$ government wants - a fat, stupid populace who will believe all their lies...

Doctors aren't God, doctors lie, they are motivated by making many, and the drug companies, make more money by keeping you alive and selling you their prescription drugs. If they ever cured anything, they would lose business, so if you suffer longer and keep treating symptoms with their "legal drugs" they make more money, they chose greed over human life and quality of life, the doctors that deny this are eithr liars, or so stupid or in denial, that they shouldn't be doctors in the first place. If they want to do honest work, doctors and the legal drug pushers should get jobs as wal mart greeters but not as walmart associates. Associates are about as stupid as tsa agents. --- Jerry Rivers

After reading this article and the comments afterwards, I still feel as though I'm uneducated. I always heard that HFCS was bad and I'm doing just fine by eliminating it from my food.

Science is a great tool to support any argument. Historically science is not always correct; it is a work in progress. Some people in the science community thought the world was flat. Let us say we have no scientific knowledge at all. If sugar is sugar, then why not use sugar. Who puts 9 teaspoons of sugar in their ice tea? 9 teaspoons of sugar in a soda! All of the positive science in support for HFCS is generated by the corn industry. This is a conflict of interest and should be dismissed as simple marketing and not good science. Their fighting for their billions and were fighting for our health. This is your choice not theirs. If you read carefully, you may see the underlying problem. Let us suppose the corn industry is 100% correct in their scientific evaluation. The HFCS is in everything, hot dog buns and ketchup! We are overdosing on HFCS/sugar. It’s very simple folks, avoid HFCS and limit your sugar intake. Why should my hot dog bun have HFCS? Just a personal note: Things taste much better without HFCS. I have no HFCS in my house.

About two months ago I bought a bunch of the Pepsi throwback soda cause it was on sale 48 cans for $10 and was too good a bargain to resist. Since I had so much of that I wasn't drinking other juices or sodas like I normally do and my teenage son was also just drinking that. For me it tasted better it tasted like the Pepsi I had as a kid. I also decided to cut out Corn Syrup as much as possible by avoiding foods that contained it. Even though I was drinking soda with sugar and eating like I normally do no change in my diet other than not eating corn syrup I lost 6 pounds in three weeks. It put me under 200 and boy was I happy!

No one is really answering the question. Does anyone know? Is it bad for you or not? I am not talking about obesity. (I could stand to gain some weight) I mean is it bad for your liver, heart, brain or kidneys. I would like to hear it from some who knows, Not someone who thinks they know something.
