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. ...
The American Beverage Association, whose members include Coca-Cola and Kraft Foods have strongly, and successfully, opposed efforts to tax soda. 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...
Sugar is half fructose.
I’m safe. I only use sucrose. ;>)
Does honey count?
I don’t know, but it wouldn’t surprise me to learn that taking in fructose from eating real fresh fruits in moderation is not unhealthy and that the various combination of nutrients found in a real fruit work together and do not promote cancer.
Kind of like how highly processed refined wheat loses a lot of the essential nutrients the body needs to use it properly.
This is badly written. It makes seem like sugar and fructose are different things. Regular table sugar is half glucose and half fructose. “High Fructose Corn Syrup”, the sweetener used in soft drinks and other foods, is 55% fructose and 45% glucose. The difference is negligible.
I think the significant element is “high fructose” corn syrup, as opposed to just fructose. I don’t eat a lot of sugar, never grew much of a sweet tooth. And for my coffee I use Splenda.
Well, the dosage is different. You won't get nearly as much fructose eating an apple as you will drinking a soda or eating a cake. But the fructose is still fructose.
Here’s something new about fructose. What do you think?
Any study that sets out to justify a proposed tax is fundamentally flawed.
if fructose feeds cancer cells...
then HIGH fructose would give them a massive jolt.
awesome. explains why Americans, fed a steady stream of high fructose products, are getting cancer
well, once reason
The fructose in high fructose corn syrup (HFCS) and the fructose in table sugar are the same fructose. HFCS just has a little more fructose.
For more about the dangers of fructose, see: http://www.nytimes.com/2011/04/17/magazine/mag-17Sugar-t.html and watch the video linked in that article.
Honey contains a lot of fructose.
Glucose takes a couple extra steps in the TCA cycle, but still ends up
at fructose 1,6-diphospate before continuing down the same metabolic path. Is it an “uptake” issue i.e. fructose is easier to transport?
If that’s the case, why don’t products that use high fructose taste the same as the same product used with real sugar?
Pepsi vs Pepsi Throwback don’t taste the same at all.
Something about high fructose tatses very fake and maufactured to me.
Any thoughts?
Yeah but what else is in it? lol
seriously, I think (and I am probably wrong) that when they brought back “classic” coke after the New Coke debacle, that the change from sugar to corn syrup is what made the classic coke still not the the original taste. It has never been the same as it was when I was a kid.
I think you misread that, if you bothered to read it at all. The website is a get-government-out-of-our lives website, not a tax advocacy group. They are the food and farm and supplement freedom people.
Wonder if this is all fructose or mainly fructose syrup. Anyone know?
Fruits are high in fructose, and many veggies, too.
Damn!
One would think such a natural thing would be better then synthetics anyway.
Sugar’s sugar....wait a minute. Are they trying to kill the sugar market now?
