Is the substitution of real sugar in our products for corn syrup and its derivatives the real cause of our ever expanding waistlines? The presenter makes a good presentation of his claim. Is anyone aware weather it is actually factual or not?
Scientists have proved for the first time that fructose, a cheap form of sugar used in thousands of food products and soft drinks, can damage human metabolism and is fueling the obesity crisis.
Fructose, a sweetener usually derived from corn, can cause dangerous growths of fat cells around vital organs and is able to trigger the early stages of diabetes and heart disease.
Over 10 weeks, 16 volunteers on a controlled diet including high levels of fructose produced new fat cells around their heart, liver and other digestive organs. They also showed signs of food-processing abnormalities linked to diabetes and heart disease. Another group of volunteers on the same diet, but with glucose sugar replacing fructose, did not have these problems.

This study takes its place in a growing lineup of scientific studies demonstrating that consuming high-fructose corn syrup is the fastest way to trash your health. It is now known without a doubt that sugar in your food, in all it’s myriad of forms, is taking a devastating toll.
And fructose in any form -- including high-fructose corn syrup (HFCS) and crystalline fructose -- is the worst of the worst!
Fructose is a major contributor to:
A Calorie is Not a CalorieAnd fructose in any form -- including high-fructose corn syrup (HFCS) and crystalline fructose -- is the worst of the worst!
Fructose is a major contributor to:
- Insulin resistance and obesity
- Elevated blood pressure
- Elevated triglycerides and elevated LDL
- Depletion of vitamins and minerals
- Cardiovascular disease, liver disease, cancer, arthritis and even gout
Glucose is the form of energy you were designed to run on. Every cell in your body, every bacterium -- and in fact, every living thing on the Earth--uses glucose for energy.
If you received your fructose only from vegetables and fruits (where it originates) as most people did a century ago, you’d consume about 15 grams per day -- a far cry from the 73 grams per day the typical adolescent gets from sweetened drinks. In vegetables and fruits, it’s mixed in with fiber, vitamins, minerals, enzymes, and beneficial phytonutrients, all which moderate any negative metabolic effects.
It isn’t that fructose itself is bad -- it is the MASSIVE DOSES you’re exposed to that make it dangerous.
There are two reasons fructose is so damaging:
Food and beverage manufacturers began switching their sweeteners from sucrose (table sugar) to corn syrup in the 1970s when they discovered that HFCS was not only far cheaper to make, it’s also about 20 times sweeter than table sugar.
This switch drastically altered the average American diet.
By USDA estimates, about one-quarter of the calories consumed by the average American is in the form of added sugars, and most of that is HFCS. The average Westerner consumes a staggering 142 pounds a year of sugar! And the very products most people rely on to lose weight -- the low-fat diet foods -- are often the ones highest in fructose.
Making matters worse, all of the fiber has been removed from these processed foods, so there is essentially no nutritive value at all.

There are two reasons fructose is so damaging:
- Your body metabolizes fructose in a much different way than glucose. The entire burden of metabolizing fructose falls on your liver.
- People are consuming fructose in enormous quantities, which has made the negative effects much more profound.

Without getting into the very complex biochemistry of carbohydrate metabolism, it is important to understand some differences about how your body handles glucose versus fructose. I will be publishing a major article about this in the next couple of months, which will get much more into the details, but for our purpose here, I will just summarize the main points.
Dr. Robert Lustighttp://articles.mercola.com/sites/a...Corn-Syrup-Alters-Human-Metabolism.aspx#_edn1 Professor of Pediatrics in the Division of Endocrinology at the University of California, San Francisco, has been a pioneer in decoding sugar metabolism. His work has highlighted some major differences in how different sugars are broken down and used:
The bottom line is: fructose leads to increased belly fat, insulin resistance and metabolic syndrome -- not to mention the long list of chronic diseases that directly result.
Panic in the Corn FieldsDr. Robert Lustighttp://articles.mercola.com/sites/a...Corn-Syrup-Alters-Human-Metabolism.aspx#_edn1 Professor of Pediatrics in the Division of Endocrinology at the University of California, San Francisco, has been a pioneer in decoding sugar metabolism. His work has highlighted some major differences in how different sugars are broken down and used:
- After eating fructose, 100 percent of the metabolic burden rests on your liver. But with glucose, your liver has to break down only 20 percent.
- Every cell in your body, including your brain, utilizes glucose. Therefore, much of it is “burned up” immediately after you consume it. By contrast, fructose is turned into free fatty acids (FFAs), VLDL (the damaging form of cholesterol), and triglycerides, which get stored as fat.
- The fatty acids created during fructose metabolism accumulate as fat droplets in your liver and skeletal muscle tissues, causing insulin resistance and non-alcoholic fatty liver disease (NAFLD). Insulin resistance progresses to metabolic syndrome and type II diabetes.
- Fructose is the most lipophilic carbohydrate. In other words, fructose converts to activated glycerol (g-3-p), which is directly used to turn FFAs into triglycerides. The more g-3-p you have, the more fat you store. Glucose does not do this.
- When you eat 120 calories of glucose, less than one calorie is stored as fat. 120 calories of fructose results in 40 calories being stored as fat. Consuming fructose is essentially consuming fat!
- The metabolism of fructose by your liver creates a long list of waste products and toxins, including a large amount of uric acid, which drives up blood pressure and causes gout.
- Glucose suppresses the hunger hormone ghrelin and stimulates leptin, which suppresses your appetite. Fructose has no effect on ghrelin and interferes with your brain’s communication with leptin, resulting in overeating.
The bottom line is: fructose leads to increased belly fat, insulin resistance and metabolic syndrome -- not to mention the long list of chronic diseases that directly result.
As the truth comes out about HFCS, the Corn Refiners Association is scrambling to convince you that their product is equal to table sugar, that it is “natural” and safe.
Of course, many things are “natural” -- cocaine is natural, but you wouldn’t want to use 142 pounds of it each year.
The food and beverage industry doesn’t want you to realize how truly pervasive HFCS is in your diet -- not just from soft drinks and juices, but also in salad dressings and condiments and virtually every processed food. The introduction of HFCS into the Western diet in 1975 has been a multi-billion dollar boon for the corn industry.
The FDA classifies fructose as GRAS: Generally Regarded As Safe. Which pretty much means nothing and is based on nothing.
There is plenty of data showing that fructose is not safe -- but the effects on the nation’s health have not been immediate. That is why we are just now realizing the effects of the last three decades of nutritional misinformation.
As if the negative metabolic effects are not enough, there are other issues with fructose that disprove its safety:

- More than one study has detected unsafe mercury levels in HFCS[ii].
- Crystalline fructose (a super-potent form of fructose the food and beverage industry is now using) may contain arsenic, lead, chloride and heavy metals.
- Nearly all corn syrup is made from genetically modified corn, which comes with its own set of risks.
Ideally, I recommend that you avoid as much sugar as possible. This is especially important if you are overweight or have diabetes, high cholesterol, or high blood pressure.
I also realize we don’t live in a perfect world, and following rigid dietary guidelines is not always practical or even possible.
If you want to use a sweetener occasionally, this is what I recommend:

If you want to use a sweetener occasionally, this is what I recommend:
- Use the herb stevia.
- Use organic cane sugar in moderation.
- Use organic raw honey in moderation.
- Avoid ALL artificial sweeteners, which can damage your health even more quickly than fructose.
- Avoid agave syrup since it is a highly processed sap that is almost all fructose. Your blood sugar will spike just as it would if you were consuming regular sugar or HFCS. Agave’s meteoric rise in popularity is due to a great marketing campaign, but any health benefits present in the original agave plant are processed out.
- Avoid so-called energy drinks and sports drinks because they are loaded with sugar, sodium and chemical additives. Rehydrating with pure, fresh water is a better choice.
