High Fructose Corn Syrup study

[barbaro]

Reminds me of the great video on "Sugar: the bitter truth" post in the health section. That doctor focused on, HFCs, High Fructose Corn Syrup.

HFCs are in many, many, things. Breads, buns, etc.

You can check on the internet to what foods have HFCs.

I thought this topic was worthy of putting here.

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. The researchers say the work sheds light on the factors contributing to obesity trends in the United States.

"Some people have claimed that high-fructose corn syrup is no different than other sweeteners when it comes to weight gain and obesity, but our results make it clear that this just isn't true, at least under the conditions of our tests," said psychology professor Bart Hoebel, who specializes in the neuroscience of appetite, weight and sugar addiction. "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. Even when rats are fed a high-fat diet, you don't see this; they don't all gain extra weight."

In results published online March 18 by the journal Pharmacology, Biochemistry and Behavior, the researchers from the Department of Psychology and the Princeton Neuroscience Institute reported on two experiments investigating the link between the consumption of high-fructose corn syrup and obesity.

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. Compared to animals eating only rat chow, rats on a diet rich in high-fructose corn syrup showed characteristic signs of a dangerous condition known in humans as the metabolic syndrome, including abnormal weight gain, significant increases in circulating triglycerides and augmented fat deposition, especially visceral fat around the belly. 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. In humans, this would be equivalent to a 200-pound man gaining 96 pounds.

"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. "In humans, these same characteristics are known risk factors for high blood pressure, coronary artery disease, cancer and diabetes." In addition to Hoebel and Bocarsly, the research team included Princeton undergraduate Elyse Powell and visiting research associate Nicole Avena, who was affiliated with Rockefeller University during the study and is now on the faculty at the University of Florida. 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.

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. In contrast, every fructose molecule in sucrose that comes from cane sugar or beet sugar is bound to a corresponding glucose molecule and must go through an extra metabolic step before it can be utilized.

This creates a fascinating puzzle. The rats in the Princeton study became obese by drinking high-fructose corn syrup, but not by drinking sucrose. The critical differences in appetite, metabolism and gene expression that underlie this phenomenon are yet to be discovered, but may relate to the fact that excess fructose is being metabolized to produce fat, while glucose is largely being processed for energy or stored as a carbohydrate, called glycogen, in the liver and muscles.

In the 40 years since the introduction of high-fructose corn syrup as a cost-effective sweetener in the American diet, rates of obesity in the U.S. have skyrocketed, according to the Centers for Disease Control and Prevention. In 1970, around 15 percent of the U.S. population met the definition for obesity; today, roughly one-third of the American adults are considered obese, the CDC reported. High-fructose corn syrup is found in a wide range of foods and beverages, including fruit juice, soda, cereal, bread, yogurt, ketchup and mayonnaise. On average, Americans consume 60 pounds of the sweetener per person every year.

"Our findings lend support to the theory that the excessive consumption of high-fructose corn syrup found in many beverages may be an important factor in the obesity epidemic," Avena said.

The new research complements previous work led by Hoebel and Avena demonstrating that sucrose can be addictive, having effects on the brain similar to some drugs of abuse.

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. Another step will be to study how fructose affects brain function in the control of appetite.

The research was supported by the U.S. Public Health Service.

HFC were introduced to the public in 1975.

Look at this chart on obesity for both men and women.

The "Codex" system is not going to help either as it restricts natural ingredients and can lebel them in the same catagory as drugs. This system will simply benefit the large pharmacutical companies as usual.

Last week I interviewed a company that looks into the developments of sugar and its uses. Some of the stuff on the market is quite shocking.

Corn syrup is really bad shit!

cane sugar really isn't so bad in moderation.
palm sugar is ok too.

Two different things, entirely.

Watch this.

It's an hour and a half - so just watch 15 minutes at a time, if it suits you.

After about 20 minutes, he starts going into the meat of the issue.

HFCs.

Many sources, books, studies, and authors you can find, that he presents.

So, avoid High Fructose Corn Syrup based foods -- not impossible, just start by avoiding processed foods, and remove soft drinks (soda pop) from your diet.

This isn't really news (High Fructose Corn Syrup is neither of those things), but I can certainly appreciate how you present it with your usual alarmist and high-urgency manner..

Simply shows a correlation, but does not prove causation.

Cane sugar (Sugar) is broken down into its components in your digestive system, the first step is to break it down to Fructose and Glucose.

Fructose and Glucose is exactly what HFCS is......

Can you explain what is different about it?

Correct.

Who are you referring to?

I'd have to find the readings and where this is in the video. I think it's after the 40 minute mark on the presentation by the doctor.

When I was in the mining / diggin holes and blasting trade the training course for your blasting ticket covered all aspects - including improvised banging stuff for emergencies in remote areas ( shifting rocks and concrete during earthquake rescue operations etc )
Corn Syrup from wrecked food stores added to bits and bobs from pharmacies and horticultural stores made a really good 'binder' and fuel for small shaped charges !!! BANG !

An hour an a half long, with a bit of BioChemistry that might be difficult to understand. To save some time here's a screenshot of the conclusions...



Watch it to see his logic behind it. I thought his ideas on the biological processes behind the HFCS and exercise were interesting.

Scariest thing is how it's in the baby formula.
