* Study shows fructose used differently from glucose
* Findings challenge common wisdom about sugars
Aug 2 (Reuters) - Pancreatic tumor cells use fructose to divide and proliferate, U.S. researchers said on Monday in a study that challenges the common wisdom that all sugars are the same.
Tumor cells fed both glucose and fructose used the two sugars in two different ways, the team at the University of California Los Angeles found.
They said their finding, published in the journal Cancer Research, may help explain other studies that have linked fructose intake with pancreatic cancer, one of the deadliest cancer types.
"These findings show that cancer cells can readily metabolize fructose to increase proliferation," Dr. Anthony Heaney of UCLA's Jonsson Cancer Center and colleagues wrote.
"They have major significance for cancer patients given dietary refined fructose consumption, and indicate that efforts to reduce refined fructose intake or inhibit fructose-mediated actions may disrupt cancer growth."
Americans take in large amounts of fructose, mainly in high fructose corn syrup, a mix of fructose and glucose that is used in soft drinks, bread and a range of other foods.
Politicians, regulators, health experts and the industry have debated whether high fructose corn syrup and other ingredients have been helping make Americans fatter and less healthy.
Too much sugar of any kind not only adds pounds, but is also a key culprit in diabetes, heart disease and stroke, according to the American Heart Association.
Several states, including New York and California, have weighed a tax on sweetened soft drinks to defray the cost of treating obesity-related diseases such as heart disease, diabetes and cancer.
The American Beverage Association, whose members include Coca-Cola (KO.N) and Kraft Foods (KFT.N) have strongly, and successfully, opposed efforts to tax soda. [ID:nN12233126]
The industry has also argued that sugar is sugar.
Heaney said his team found otherwise. They grew pancreatic cancer cells in lab dishes and fed them both glucose and fructose.
Tumor cells thrive on sugar but they used the fructose to proliferate. "Importantly, fructose and glucose metabolism are quite different," Heaney's team wrote.
"I think this paper has a lot of public health implications. Hopefully, at the federal level there will be some effort to step back on the amount of high fructose corn syrup in our diets," Heaney said in a statement....

I've lately been obsessed with learning about sugar. Our food is loaded with sugar (sucrose), which is half fructose. Fructose is not good for our health. It appears to encourage cancer cell growth, it seems to negatively affect memory, it definitely increases uric acid output, which increases your odds of getting gout and hypertension. Also, somewhere around 30% of the food energy from the fructose goes right from the liver into fat stores. Fructose suppresses Ghrelin, which causes you to be hungry. Those two features of Fructose seem to help explain the non linear weight gain that Americans are experiencing.
Please watch this video, it will open your mind about sugar and fructose.
http://www.youtube.com/watch?v=dBnniua6-oM&feature=channel
Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology, explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.
Some of the takeaways from this video are that Fructose is bad. Fructose is digested mostly in the liver. Somewhere around 30% of the food energy from fructose goes right into fat stores from the liver. It also results in increased uric acid output, which makes you more likely to get gout and hypertension. Increased uric acid output increases blood pressure. Eating fructose also suppresses Ghrelin, which causes you to be hungry.
Sucrose (table sugar, cane sugar, cane juice), is half fructose.
The Wiki on Fructose and sucrose are interesting reading, too:
http://en.wikipedia.org/wiki/Fructose
The Entries for "Liver Disease', 'Digestive Problems", "Metabolic syndromes", and "Gout" are food for thought. What it does to your liver sounds nasty.
http://en.wikipedia.org/wiki/Sucrose
Sucrose is half fructose!
This article from The Journal of Clinical Endocrinology & Metabolism says some of the same things:
"Dietary Fructose Reduces Circulating Insulin and Leptin, Attenuates Postprandial Suppression of Ghrelin, and Increases Triglycerides in Women"
http://jcem.endojournals.org/cgi/content/full/jcem;89/6/2963
It appears that Fructose impairs our memory as well!
"How Fructose Impairs the Memory"
http://www.scientificamerican.com/article.cfm?id=forget-the-fructose&sc=CAT_...
Even though normal cells in your body can not metabolize fructose directly, it appears that cancer cells can metabolize fructose to speed cancer growth!
"Pancreatic tumor cells use fructose to divide and proliferate, U.S. researchers said on Monday in a study that challenges the common wisdom that all sugars are the same."

After learning more about Fructose, I'm attempting to cut it out of my diet.
If you're also curious about what sweeteners might be safe, it appears that Glucose, the sugar of life, is safe. Every cell in your body can metabolize it.
The commercial sweetener, dextrose, is glucose. So is plain 'corn syrup' (but not high fructose corn syrup):
http://en.wikipedia.org/wiki/Corn_syrup
The Wikipedia entry for glucose is interesting:
http://en.wikipedia.org/wiki/Glucose
Under 'Function':
"Scientists can speculate on the reasons why glucose, and not another monosaccharide such as fructose (Fru), is so widely used in organisms. One reason might be that glucose has a lower tendency, relative to other hexose sugars, to react non-specifically with the amino groups of proteins. This reaction (glycation) reduces or destroys the function of many enzymes. The low rate of glycation is due to glucose's preference for the less reactive cyclic isomer."
That paragraph seems to be saying that glucose is much less likely to mess with proteins and enzymes in your body than fructose is.
One of my friends said that she cooks with Brown Rice Syrup. It appears to have no fructose, consisting of the sugar of life, glucose, according to the Wiki entries
http://en.wikipedia.org/wiki/Brown_rice_syrup
http://en.wikipedia.org/wiki/Maltotriose
Maltose in beer also seems to be the safe sugar, Glucose
http://en.wikipedia.org/wiki/Maltose
The Wiki on Beer is interesting, too:
"Several diet books quote beer as having an undesirably high glycemic index of 110, the same as maltose; however, the maltose in beer undergoes metabolism by yeast during fermentation so that beer consists mostly of water, hop oils and only trace amounts of sugars, including maltose."

High fructose corn syrup, corn sugar, corn syrup, or any other name you may have for it, is highly controversial. However, there are a lot of myths about this sweetener, listed here.

A new study on cancer shows some interesting results. It seems that cancer cells actually feed off of fructose. In this study, it was proven that fructose quickened the growth rate of cancer cells. Considering the fact that high-fructose corn syrup is in so many processed foods, this could be a huge breakthrough.A new study on cancer shows some interesting results.

Shocking! This ‘Tequila’ Sweetener is Far Worse than High Fructose Corn Syrup
Posted by Dr. Mercola
March 30 2010
many people interested in staying healthy have switched to agave as a safer “natural” sweetener. They want to avoid well documented dangerous sweeteners like HFCS (high fructose corn syrup) but are unaware that agave is actually WORSE than HFCS.
So just what is agave ?
