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.

I am NOT a doctor BUT I do know that I hardly ate anything and was gaining, and gaining, and gaining. I stayed away from sodas and most of the time "other" junk food, but blew up like a helium balloon. I cut out high fructose corn syrup by 99%, and by the end of the first week, I lost FOUR (4) dress sizes. I am still losing weight. I am convinced that high fructose corn syrup does affect people negatively. I eat products that contain real sugar, and I do NOT blow up like a helium balloon like I did with high fructose corn syrup. I am NOT looking to get those of you who support high fructose corn syrup all bent out of shape BUT, you need to consider the possibility that some humans can not consume your "fake" sugar. Like there are people who are gluten intolerant, others allergic to seafood and shellfish, others lactose intolerant, some allergic to peanuts, I do believe there are those who can not consume YOUR product and I AM ONE OF THEM.

High fructose corn syrup is made from corn...what does corn have?
GMO's!!! Double whammy!!!

Obviously poor Joyce has never taken a Chemistry class. Metabolic breakdown has everything to do with how our bodies respond to what we put in our mouths. HFCS is metabolized very differently then regular sugar and is similar to ETOH as it is broken down by the liver and therefore may contribute to the same type of diseases you would see with alcoholism. . Fatty liver, diabetis type 2, and heart disease. In this process there is also a breakdown of certain enzymes that result in higher then normal levels of uric acid which can contribute to other health problems such as gout. This doesn't even touch on the obesity issue and all the secondary health issues from this.

Corn (where HFCS comes from) is used in the beef industry to FATTEN cattle! So...

Actually The article is not entirely correct. Sugar is not sugar is not sugar as they imply. Your brain has glucose receptors and releases several peptides which signal either hunger or full. Those receptors do not recognize fructose, high fructose, corn sugar or whatever you want to call it. Yes, you have to watch calories, that part is true. But, especially kids will be hungry all the time if they have a diet high in high fructose corn syrup regardless of caloric intake because their brain will not signal full.
This gives them a tendency to snack.
Try this all of you. drink a large diet coke.
Now drink the same size coke with sugar in it (those glass bottled ones from Mexico). You will be able to tell the difference.

I challenge all of you to eat the same caloric intake with only sugar, no high fructose corn syrup and no diet sugar substitutes. First you will feel full and eat less, then you will lose weight. I have taught metabolism and biochemistry at a University for 32 years. On average, my students who take this challenge lose about 30 pounds in a 4 and a half month semester.

One other thing, the person who wrote the article should also be aware that fructose does not go across the gut like glucose does. It passes through the liver and tends to get metabolized to glycerol which is the backbone of a triglyceride. This causes a fatty liver and it is what contributes to metabolic Syndrome, also known as a pre-diabetic condition. Hope this helps you all to be healthy. from Dr. Dee Takemoto

I am a weightloss surgeon, the author is stating an overwhelming fact..... a third of the worlds populuation is now overweight, and will be diabetic by 2020. You dont need to a degree or M.D. to see the obvious.
