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

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.

HFCS is bad. It is true that people can be allergic to a part of corn. Because I am and so are my older brother and sister. It isn't really severe, but it does hinder us in ways. We really have to watch our food choices and try and find substitutes. But it's hard to find good substitutes for corn syrup on a tight budget in the modern economy. And we could use corn for better uses than a sweetner, it helps to feed cattle, so our farmers our having to pay more therefore making them raise their prices for the food companies, making us pay for it out of our wallet at the store. When all this could stop simply by finding another sweetner other than HFCS, and maybe a better one at that. You all may have different opinions than what I say because you don't go through the same things, but I'll leave you with one more point. HFCS is a bad choice because, our body is made to process sugar not corn syrup so when we eat corn syrup it may seem like sugar but chemically the structure is entirely different than sugar so our body struggles to use it and you won't really see the effects of it but that's because they're on the inside and you can be doing damage without knowing it.

Sugar is fuel for your body. Sugar is not bad because it's sugar. REFINED/ISOLATED sugar/syrup is bad because of the LACK of vitamins, minerals, antioxidants, fibers.. All those missing things are what helps the body to handle, repair and detox the damage done by processed sugar. Technically I asume that HFCS is ok if you add all those micronutrients back in, just make sure that it's not a reduced version. Adding a few other refined nutrients is not good enuff. Nature is still too complex for the arrogant scientist to fully copy/synthesize, but if you take an apple and then ferment it so that the sugars turn into either alcohol or acids, and then vaporize it, you will end up with an apple without sugar. Then add HFCS and the result will be something similar to a cooked apple, still containing most micronutrients with the sugar content exchanged with another nearly identical sugar/syrup. I don't believe that it matter that much if the corn is GMO. The end product of HFCS is so refined that any GMO mutations are gone. The reason why some men's hormones are screwed up (creating "manboobs") is because of estrogen in beer, soy lecithin, plastic bottles, etc.. it's not because of sugar... maybe very indirectly, but only because of lack of hormone balancing micronutrients, but not the sugar itself..

How to make orange juice...
Squeeze fresh oranges

Why do companies even think to put 10 ingredients in something that nature already made perfectly. A lot of things do not even need HFCS because they're inherently sweet, so why is it in there? I don't know if I agree with the bias-riddled "science" saying that HFCS is all natural and even healthy sugar for your body. It's like Cocaine from Corn. It's the next asbestos just waiting to happen... It was the perfect cheap insulation until we discovered how dangerous it was. "Oh wow, here's a really cheap sugar we can use for everything... until they find out it causes cancer and birth defects" says big industry.

It's not only about which sugar to use. It's about using any adorning ingredients at all... MSG, Aspartame, HFCS, Soy Lecithin, Maltodextrin... The list goes on. We are forced to eat food-like product instead of just growing things and eating them like our ancestors did for centuries without many problems. How can we figure out scientific dog food formulas that make my dog strong, lean, and have a shiny coat... but the human diet has been so neglected. I don't want to sound like a conspiracy theorist, but I do feel like there is more going on here than meets the eye. Henry Ford built a Model-T car out of plastic made from Hemp, which is much stronger and lighter than steel, and it ran on Hemp fuel. Big oil companies came in and vilified Hemp as a drug. It may be related to a drug, but industrial hemp is not at all possible to use in that way. DuPont and other companies banned together to shut down every idea that did not include using their products for everything... messed up. That's what capitalism gets you. Maybe there's something going on with the companies that produce HFCS. Why are the companies that just make regular food forced to put special labels on their products saying they are organic and so on. It should be the other way around. Their products are just food, as you would expect to buy it. It should read... "Genetically Modified, Chemically Enhanced, Preserved Ketchup" Forget the FDA, you really think they're out to help you?

"If the people let government decide what foods they eat and what medicines they take, their bodies will soon be in as sorry a state as are the souls of those who live under tyranny." - Thomas Jefferson

corn syrup is so bad for you as it comes from corn, but it's NOT natural corn but GMO corn which the latest studies show that it leads to cancer
(just search on google or youtube)
you will be shocked

A difference of 10% is not "identical." Where does the extra 10% go that cannot be metabolized? Don't listen to propaganda from processed food companies that would have you sick and obese so the pharmaceutical companies will get richer.
Give up high fructose corn syrup and anything that it is in. Give up artificial chocolate with PGPR (Polyglycerol Polyricinoleate). Say goodby to Hershey's and any other company that thinks making things artificial will make them richer.
We need to love our children enough to feed them real foods.

I agree with the rest of the anonymous commentators. It may be chemically equivalent to normal sugar or sucrose; however if the corn that the HFCS derives from is GMO corn then it can cause a hormone imbalance* which even though may be the same calories as regular sugar causes are bodies to act abnormally. Delete this article, you were probably paid to post this.

Your body does NOT process it like it is sugar. It doesn't know how to deal with it since it is foreign. What happens is it sits inside you and becomes cellulite. Look at the saddlebags on everyone these days. The boobies on men. There is fat in strange places. The world is drowning in the folds of their own bodies.

Sugar is not so bad - in small quantities; however, with HFCS you can add the sugar to most everything and thereby greatly increase the total ingestion of sugars. This may be good if you are engaged is strenuous physical activity, but if your activity is video games, you will gradually be transformed into part of your couch and take a potato shape. Sucrose is composed of dextrose (glucose) and fructose. The dextrose can be readily used by your cells for energy, but the fructose is a bit different. Fructose must first go to the liver for modifications before it can be utilized. Excess fructose is also more readily incorporated into fat than is dextrose. Too bad! The corn syrup stars out as potentially dextrose, but then the dextrose is not sweet enough, so the corn industry enzymatically converts about half of the dextrose to fructose. (Fructose is much sweeter than Dextrose). Recently, work has been published to the effect that the obesity epidemic is more close tied to our consumption of sugar - that it is to our consumption of fat.

If you have HFCS you will gain a lot of weight
