Consumption of high-fructose corn syrup in beverages may play a role in the epidemic of obesity

2011-09-17T01:12:00.000-07:00

Consumption of high-fructose corn syrup in beverages may play a role in the epidemic of obesity

We analyzed food consumption patterns by using US Department of Agriculture food consumption tables from 1967 to 2000. The consumption of High Fructose Corn Syrup increased > 1000% between 1970 and 1990, far exceeding the changes in intake of any other food or food group.

The increased use of High Fructose Corn Syrup in the United States mirrors the rapid increase in obesity. Hepatic metabolism of fructose favors de novo lipogenesis. In addition, unlike glucose, fructose does not stimulate insulin secretion or enhance leptin production. Furthermore, calorically sweetened beverages may enhance caloric overconsumption. Thus, the increase in consumption of High Fructose Corn Syrup has a temporal relation to the epidemic of obesity, and the over consumption of High Fructose Corn Syrup in calorically sweetened beverages may play a role in the epidemic of obesity.

High Fructose Corn Syrup:What Does It All Mean?

If High Fructose Corn Syrup HFCS is one of the first ingredients listed on a food label, don’t eat it. Make a mental list of the worst culprits, such as regular soft drinks and many highly sweetened breakfast cereals. High Fructose Corn Syrup HFCS alone won’t make you fat, but when HFCS is high on the ingredient list, the food is not the best choice. As part of a lifestyle that has many of us eating too much and moving too little, we’re putting our health at risk if we don’t choose our foods carefully.

So what’s the answer? It’s easy. Avoid High Fructose Corn Syrup HFCS by reading food labels and shopping the grocery store’s perimeter: Produce is on one side, seafood, meat and poultry on another, and dairy products, eggs and bread on the third. Avoid the center aisles, which are mostly stocked with highly processed foods.

The more you stick to fresh whole foods and avoid commercial and highly processed foods, the less HFCS you will consume.

High Fructose Corn Syrup: What It Means to You and Your Diabetes

As a person with diabetes, you know how important it is to control your blood glucose and insulin levels to avoid complications. So, it would seem that a lack of glucose and insulin secretion from fructose consumption would be a good thing.

However, insulin also controls another hormone, leptin, so its release is necessary.

Leptin tells your body to stop eating when it’s full by signaling the brain to stop sending hunger signals. Since fructose doesn’t stimulate glucose levels and insulin release, there’s no increase in leptin levels or feeling of satiety. This can leave you ripe for unhealthy weight gain.

Understanding Glucose and Fructose

Understanding Glucose and Fructose

Since High Fructose Corn Syrup HFCS is a blend of glucose and fructose, it’s important to understand the role each plays in your body. All sugars, indeed all carbohydrates, have four calories per gram.

But that is just part of the story.

Glucose (dextrose) is a monosaccharide (basically, a simple sugar), which is the form of sugar that is transported in the blood and is used by the body for energy. This is what you measure when testing your blood glucose or blood “sugar.”

Fructose is also a monosaccharide and is often referred to as “fruit sugar,” because it is the primary carbohydrate in most fruits. It’s also the primary sugar in honey and half the carbohydrate in sucrose (table sugar). However, fructose does not stimulate insulin secretion or require insulin to be transported into cells, as do other carbohydrates.

HIGH FRUCTOSE CORN SYRUP HFCS—It’s Here to Stay

Today, food companies use High Fructose Corn Syrup HFCS—a mixture of fructose and glucose—because it’s inexpensive, easy to transport and keeps foods moist. And because High Fructose Corn Syrup HFCS is so sweet, it’s cost effective for companies to use small quantities of HCFS in place of other more expensive sweeteners or flavorings.

For these reasons and others, High Fructose Corn Syrup HFCS isn’t going away any time soon.

That is why, to best manage diabetes, you need to know what HFCS is and how to identify it in products.

The Dangers of High Fructose Corn Syrup

This article was originally published in Diabetes Health in May, 2005.

You know how important it is to control the sugar and carbohydrates in your diet. So you read food labels and listen to your body cues to make sure you’re getting what you need to stay healthy.

But what happens when a manufacturer disguises sugar as something you don’t recognize?

Unfortunately, this is not uncommon. In fact, one of the more popular aliases for sugar today is high fructose corn syrup (HFCS)—a corn-based sweetener that has been on the market since approximately 1970.

According to a commentary in the April 2004 issue of the American Journal of Clinical Nutrition, between 1970 and 1990, the consumption of high fructose corn syrup HFCS increased over 1,000 percent.

“high fructose corn syrup HFCS now represents more than 40 percent of caloric sweeteners added to foods and beverages and is the sole caloric sweetener in soft drinks in the United States,” write George A. Bray, Samara Joy Nielsen and Barry M. Popkin, the authors of the commentary.

What are the concerns about high-fructose corn syrup?

High-fructose corn syrup is a common sweetener and preservative. High-fructose corn syrup is made by changing the sugar (glucose) in cornstarch to fructose — another form of sugar. The end product is a combination of fructose and glucose. Because it extends the shelf life of processed foods and is cheaper than sugar, high-fructose corn syrup has become a popular ingredient in many sodas, fruit-flavored drinks and other processed foods.

So far, research has yielded conflicting results about the effects of high-fructose corn syrup. For example, various early studies showed an association between increased consumption of sweetened beverages (many of which contained high-fructose corn syrup) and obesity. But recent research — some of which is supported by the beverage industry — suggests that high-fructose corn syrup isn't intrinsically less healthy than other sweeteners, nor is it the root cause of obesity.

While research continues, moderation remains important. Many beverages and other processed foods made with high-fructose corn syrup and other sweeteners are high in calories and low in nutritional value. Regularly including these products in your diet has the potential to promote obesity — which, in turn, promotes conditions such as type 2 diabetes, high blood pressure and coronary artery disease.

If you're concerned about the amount of high-fructose corn syrup or other sweeteners in your diet, consider these helpful tips:

* Limit processed foods.
* Avoid foods that contain added sugar.
* Choose fresh fruit rather than fruit juice or fruit-flavored drinks. Even 100 percent fruit juice has a high concentration of sugar.
* Choose fruit canned in its own juices instead of heavy syrup.
* Drink less soda.
* Don't allow sweetened beverages to replace milk, especially for children.

The World of High-Fructose Corn Syrup

The World of High-Fructose Corn Syrup

Think of sugar and you think of sugar cane or beets. Extraction of sugar from sugar cane spurred the colonization of the New World. Extraction of sugar from beets was developed during the time of Napoleon so that the French could have sugar in spite of the English trading blockade.

Nobody thinks of sugar when they see a field of corn. Most of us would be surprised to learn that the larger percentage of sweeteners used in processed food comes from corn, not sugar cane or beets.

The process for making the sweetener high fructose corn syrup (HFCS) out of corn was developed in the 1970s. Use of HFCS grew rapidly, from less than three million short tons in 1980 to almost 8 million short tons in 1995. During the late 1990s, use of sugar actually declined as it was eclipsed by HFCS. Today Americans consume more High Fructose Corn Syrup than sugar.

High-fructose corn syrup (HFCS) is produced by processing corn starch to yield glucose, and then processing the glucose to produce a high percentage of fructose. It all sounds rather simple--white cornstarch is turned into crystal clear syrup. However, the process is actually very complicated. Three different enzymes are needed to break down cornstarch, which is composed of chains of glucose molecules of almost infinite length, into the simple sugars glucose and fructose.

First, cornstarch is treated with alpha-amylase to produce shorter chains of sugars called polysaccharides. Alpha-amylase is industrially produced by a bacterium, usually Bacillus sp. It is purified and then shipped to High Fructose Corn Syrup manufacturers.

Next, an enzyme called glucoamylase breaks the sugar chains down even further to yield the simple sugar glucose. Unlike alpha-amylase, glucoamylase is produced by Aspergillus, a fungus, in a fermentation vat where one would likely see little balls of Aspergillus floating on the top.

The third enzyme, glucose-isomerase, is very expensive. It converts glucose to a mixture of about 42 percent fructose and 50-52 percent glucose with some other sugars mixed in. While alpha-amylase and glucoamylase are added directly to the slurry, pricey glucose-isomerase is packed into columns and the sugar mixture is then passed over it. Inexpensive alpha-amylase and glucoamylase are used only once, glucose-isomerase is reused until it loses most of its activity.

There are two more steps involved.
First is a liquid chromatography step that takes the mixture to 90 percent fructose.
Finally, this is back-blended with the original mixture to yield a final concentration of about 55 percent fructose--what the industry calls high fructose corn syrup.

High Fructose Corn Syrup has the exact same sweetness and taste as an equal amount of sucrose from cane or beet sugar but it is obviously much more complicated to make, involving vats of murky fermenting liquid, fungus and chemical tweaking, all of which take place in one of 16 chemical plants located in the Corn Belt. Yet in spite of all the special enzymes required, High Fructose Corn Syrup is actually cheaper than sugar. It is also very easy to transport--it's just piped into tanker trucks. This translates into lower costs and higher profits for food producers.

The development of the High Fructose Corn Syrup process came at an opportune time for corn growers. Refinements of the partial hydrogenation process had made it possible to get better shortenings and margarines out of soybeans than corn. High Fructose Corn Syrup took up the slack as demand for corn oil margarine declined. Lysine, an amino acid, can be produced from the corn residue after the glucose is removed. This is the modus operandi of the food conglomerates--break down commodities into their basic components and then put them back together again as processed food.

Today High Fructose Corn Syrup is used to sweeten jams, condiments like ketchup, and soft drinks. It is also a favorite ingredient in many so-called health foods. Four companies control 85 percent of the $2.6 billion business--Archer Daniels Midland, Cargill, Staley Manufacturing Co. and CPC International. In the mid-1990s, ADM was the object of an FBI probe into price fixing of three products--HFCS, citric acid and lysine--and consumers got a glimpse of the murky world of corporate manipulation.

There's a couple of other things that consumers should know about High Fructose Corn Syrup. According to a food technology expert, two of the enzymes used, alpha-amylase and glucose-isomerase, are genetically modified to make them more stable. Enzymes are actually very large proteins and through genetic modification specific amino acids in the enzymes are changed or replaced so the enzyme's "backbone" won't break down or unfold. This allows the industry to get the enzymes to higher temperatures before they become unstable.

Consumers trying to avoid genetically modified foods should avoid High Fructose Corn Syrup. It is almost certainly made from genetically modified corn and then it is processed with genetically modified enzymes. I've seen some estimates claiming that virtually everything--almost 80 percent--of what we eat today has been genetically modified at some point. Since the use of HFCS is so prevalent in processed foods, those figures may be right.

But there's another reason to avoid High Fructose Corn Syrup. Consumers may think that because it contains fructose--which they associate with fruit, which is a natural food--that it is healthier than sugar. A team of investigators at the USDA, led by Dr. Meira Field, has discovered that this just ain't so.

Sucrose is composed of glucose and fructose. When sugar is given to rats in high amounts, the rats develop multiple health problems, especially when the rats were deficient in certain nutrients, such as copper. The researchers wanted to know whether it was the fructose or the glucose moiety that was causing the problems. So they repeated their studies with two groups of rats, one given high amounts of glucose and one given high amounts of fructose. The glucose group was unaffected but the fructose group had disastrous results. The male rats did not reach adulthood. They had anemia, high cholesterol and heart hypertrophy--that means that their hearts enlarged until they exploded. They also had delayed testicular development. Dr. Field explains that fructose in combination with copper deficiency in the growing animal interferes with collagen production. (Copper deficiency, by the way, is widespread in America.) In a nutshell, the little bodies of the rats just fell apart. The females were not so affected, but they were unable to produce live young.

High Fructose Corn Syrup contains more fructose than sugar and this fructose is more immediately available because it is not bound up in sucrose. Since the effects of fructose are most severe in the growing organism, we need to think carefully about what kind of sweeteners we give to our children. Fruit juices should be strictly avoided--they are very high in fructose--but so should anything with High Fructose Corn Syrup

High Fructose Corn Syrup:

High Fructose Corn Syrup is not the cause of illness and overweight. It is another type of sugar

How much sugar does the average American consume?

This question is more difficult than it seems as until the 1970s most of the sugar we ate came from sugar beets or sugar cane and was called sucrose. In the 70s, sugar from corn - corn syrup, fructose, dextrose, dextrine, and or high fructose corn syrup began to gain popularity as a sweetener because it was much less expensive to produce. Many publications have claimed that we are eating less sugar than ten years ago, but while we are eating less sugar, we are eating more corn sweeteners.

Corn sweeteners comes under the subject of a processed sugar. Why do food processors use it?

High Fructose Corn Syrup {HFCS) is extremely soluble and mixes well in many foods.. It retains moisture, resists drying out, controls crystallization, prevents microbiological growth and blends easily with sweeteners, acids, and flavorings. Best of all for manufacturers, it makes sugar drinks taste better and is cheaper than sugar.

From the point of view of soda makers, High Fructose Corn Syrup HFCS is a revolutionary advance in food science.

This means if these products are "steamed" they may get gummy. Thus, if there is a fast-food hamburger place that precooks and wraps their product, they may prefer the firmer product (sugar); If you doubt that they use sugar at fast food restaurants, ask for their nutritional publications. It's a processed food and like any processed foods it creates problems. When sugar is consumed in high quantities as "liquid candy" (High Fructose Corn Syrup HFCS in processed drinks and foods), unused amounts are stored as fat cells.

High-fructose corn syrup prompts considerably more weight gain

2010-06-17T01:04:00.000-07:00

Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain

A Princeton University research team has demonstrated that all sweeteners are not equal when it comes to weight gain: Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.

In addition to causing significant weight gain in lab animals, long-term consumption of high-fructose corn syrup also led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides. "When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they're becoming obese -- every single one, across the board. Hoebel lab

The first study showed that male rats given water sweetened with high-fructose corn syrup in addition to a standard diet of rat chow gained much more weight than male rats that received water sweetened with table sugar, or sucrose, in conjunction with the standard diet. The concentration of sugar in the sucrose solution was the same as is found in some commercial soft drinks, while the high-fructose corn syrup solution was half as concentrated as most sodas.

The second experiment -- the first long-term study of the effects of high-fructose corn syrup consumption on obesity in lab animals -- monitored weight gain, body fat and triglyceride levels in rats with access to high-fructose corn syrup over a period of six months. Male rats in particular ballooned in size: Animals with access to high-fructose corn syrup gained 48 percent more weight than those eating a normal diet.

"These rats aren't just getting fat; they're demonstrating characteristics of obesity, including substantial increases in abdominal fat and circulating triglycerides," said Princeton graduate student Miriam Bocarsly. The Princeton researchers note that they do not know yet why high-fructose corn syrup fed to rats in their study generated more triglycerides, and more body fat that resulted in obesity.

Hoebel lab

When male rats were given water sweetened with high-fructose corn syrup in addition to a standard diet of rat chow, the animals gained much more weight than male rats that received water sweetened with table sugar, or sucrose, along with the standard diet. High-fructose corn syrup and sucrose are both compounds that contain the simple sugars fructose and glucose, but there at least two clear differences between them.

First, sucrose is composed of equal amounts of the two simple sugars -- it is 50 percent fructose and 50 percent glucose -- but the typical high-fructose corn syrup used in this study features a slightly imbalanced ratio, containing 55 percent fructose and 42 percent glucose. Larger sugar molecules called higher saccharides make up the remaining 3 percent of the sweetener.

Second, as a result of the manufacturing process for high-fructose corn syrup, the fructose molecules in the sweetener are free and unbound, ready for absorption and utilization. The rats in the Princeton study became obese by drinking high-fructose corn syrup, but not by drinking sucrose. High-fructose corn syrup is found in a wide range of foods and beverages, including fruit juice, soda, cereal, bread, yogurt, ketchup and mayonnaise. In the future, the team intends to explore how the animals respond to the consumption of high-fructose corn syrup in conjunction with a high-fat diet -- the equivalent of a typical fast-food meal containing a hamburger, fries and soda -- and whether excessive high-fructose corn syrup consumption contributes to the diseases associated with obesity.

High Fructose Corn Syrup in Food

High fructose corn syrup
often plays a key role in the integrity of food and beverage products that has little to do with sweetening.

Here are some examples in popular products:

Baked goods	High fructose corn syrup gives a pleasing brown crust to breads and cakes; contributes fermentable sugars to yeast-raised products; reduces sugar crystallization during baking for soft-moist textures; enhances flavors of fruit fillings.
Yogurt	High fructose corn syrup provides fermentable sugars; enhances fruit and spice flavors; controls moisture to prevent separation; regulates tartness.
Spaghetti sauces, ketchup, and condiments	High fructose corn syrup enhances flavor and balance – replaces the “pinch of table sugar" grandma added to enhance spice flavors; balances the variable tartness of tomatoes.
Beverages	High fructose corn syrup provides greater stability in acidic carbonated sodas than sucrose; flavors remain consistent and stable over the entire shelf- life of the product.
Granola, breakfast and energy bars	High fructose corn syrup enhances moisture control, retards spoilage and extends product freshness; provides soft texture; enhances spice and fruit flavors.
Canned and frozen fruits	High fructose corn syrup protects the firm texture of canned fruits and reduces freezer burn in frozen fruits; enhances fruit flavors.
Frozen beverage concentrates	High fructose corn syrup has a lower freezing point, so frozen beverage concentrates have the added convenience of being pourable straight from the freezer and easier for consumers to thaw and mix with water.

Study Finds High-Fructose Corn Syrup Contains Mercury

2009-07-30T23:52:00.000-07:00

Study Finds High-Fructose Corn Syrup Contains Mercury

Almost half of tested samples of commercial high-fructose corn syrup (HFCS) contained mercury, which was also found in nearly a third of 55 popular brand-name food and beverage products where high-fructose corn syrup is the first- or second-highest labeled ingredient, according to two new U.S. studies.

High-fructose corn syrup has replaced sugar as the sweetener in many beverages and foods such as breads, cereals, breakfast bars, lunch meats, yogurts, soups and condiments. On average, Americans consume about 12 teaspoons per day of HFCS, but teens and other high consumers can take in 80 percent more HFCS than average.

"Mercury is toxic in all its forms. Given how much high-fructose corn syrup is consumed by children, it could be a significant additional source of mercury never before considered. We are calling for immediate changes by industry and the [U.S. Food and Drug Administration] to help stop this avoidable mercury contamination of the food supply," the Institute for Agriculture and Trade Policy's Dr. David Wallinga, a co-author of both studies, said in a prepared statement.
ad_icon

In the first study, published in current issue of Environmental Health, researchers found detectable levels of mercury in nine of 20 samples of commercial high-fructose corn syrup.

And in the second study, the Institute for Agriculture and Trade Policy (IATP), a non-profit watchdog group, found that nearly one in three of 55 brand-name foods contained mercury. The chemical was found most commonly in high-fructose corn syrup-containing dairy products, dressings and condiments.

But an organization representing the refiners is disputing the results published in Environmental Health.

"This study appears to be based on outdated information of dubious significance," said Audrae Erickson, president of the Corn Refiners Association, in a statement. "Our industry has used mercury-free versions of the two re-agents mentioned in the study, hydrochloric acid and caustic soda, for several years. These mercury-free re-agents perform important functions, including adjusting pH balances."

However, the IATP told the Minneapolis Star Tribune that four plants in Georgia, Tennessee, Ohio and West Virginia still use "mercury-cell" technology that can lead to contamination.

IATP's Ben Lilliston also told HealthDay that the Environmental Health findings were based on information gathered by the FDA in 2005.

And the group's own study, while not peer-reviewed, was based on products "bought off the shelf in the autumn of 2008," Lilliston added.

The use of mercury-contaminated caustic soda in the production of HFCS is common. The contamination occurs when mercury cells are used to produce caustic soda.

"The bad news is that nobody knows whether or not their soda or snack food contains high-fructose corn syrup made from ingredients like caustic soda contaminated with mercury. The good news is that mercury-free HFCS ingredients exist. Food companies just need a good push to only use those ingredients," Wallinga said in his prepared statement.
