A Popular Sugar Additive May Have Fueled the Spread of Two Superbugs (latimes.com)
Zorro (Slashdot reader #15,797) quotes the Los Angeles Times:
Two bacterial strains that have plagued hospitals around the country may have been at least partly fueled by a sugar additive in our food products, scientists say. Trehalose, a sugar that is added to a wide range of food products, could have allowed certain strains of Clostridium difficile to become far more virulent than they were before, a new study finds. The results, described in the journal Nature, highlight the unintended consequences of introducing otherwise harmless additives to the food supply.
Nearly half a million people were sickened by C. difficile in 2011, when it was directly linked to 15,000 deaths. "The misuse and overuse of antibiotics has long been thought to be responsible for the rise of many kinds of antibiotic-resistant 'superbug'," notes the article, before citing a researcher who now believes "the circumstantial and experimental evidence points to trehalose as an unexpected culprit."

It seems like this 'highlights' one unique and unproven possibility, and nothing more. Getting ahead of ourselves....
I was pissed that I had to click on the stupid article link just to find out the name of the sugar, so there it is.
From Wikipedia:
Trehalose, also known as mycose or tremalose, is a natural alpha-linked disaccharide formed by an ,-1,1-glucoside bond between two -glucose units. In 1832, H.A.L. Wiggers discovered trehalose in an ergot of rye,[3] and in 1859 Marcellin Berthelot isolated it from trehala manna, a substance made by weevils, and named it trehalose.[4] It can be synthesised by bacteria,[5] fungi, plants, and invertebrate animals. It is implicated in anhydrobiosis—the ability of plants and animals to withstand prolonged periods of desiccation. It has high water retention capabilities, and is used in food and cosmetics.

Trehalose may have contributed to the problem, just maybe.
Saying overuse of antibiotics is not the primary cause is a raft of shit.
The author obviously has an agenda.
the article isn't worth the electricity it cost to light up my screen.
You may want to consider using that wording very carefully. The number of cancer cases per capita in the west has literally grown ten-fold during the 1900's, with the increased usage of chemical additives we considered "harmless".
And shame on both the LA Times and /. for not ensuring that there was a link to the original article or at least a DOI.
Reader beware.
I've never trusted artificial sweateners. Call it irrational if you want but they just seem like getting something for nothing and I don't trust that. In this case we just discovered Trehalose's hidden "price".
I have a close friend who has been diagnosed c.diff free for almost three months now. It took him years of discomfort and our last line drug for the disease (which apperently is new enough insurance companies arent covering it yet) to get to this point.
To improve my own diet I just ate less and less sweet stuff over time. After a while you don't crave it any more.

Hillary lost the election. Get over it.
to get rid of the sugar import tax? And for the FDA to rescind some of the crap they allow in food products.
Very little sugar is still grown in the states so which farmers are being protected and how is the populace benefitting from this tax?
Yes, too much sugar is bad for you but, it seems like the corn sugar and the other products that are being used as a substitute for sugar are worse for the consumer.
I attribute this to the price of imported sugar being high, if the import tax on sugar has ANY bearing on this issue it's time to take action.
The upside of this is I don't purchase or consume much of these products because I read the labels and avoid particularly yellow #5 and sugar substitutes.
I prefer home made sweets where I can control the ingredients.
The FDA has allowed the use of these compounds (to the benefit of the corporations) based on their "recommended" consumption guidelines.
It is becoming obvious that the prolonged consumption of these products is harming the populace.
It's obvious that the populace is unable to police themselves and follow obscure product warnings, why are they still allowed to be used?

Summary reads as though it was written by someone with a stake in the price of trehalose, calling it "otherwise harmless". A bullet can kill you if it enters your body at high speed, but they're are otherwise harmless; we still don't allow people to shoot guns randomly so long as they're not aiming at someone. I'd just like to point out that "otherwise harmless" is a weasel-word for "harmful".
APK quotes people (including myself) without context and should not be trusted. Just thought you should know.
Yes and no. What they propose is happening is that Cdiff, which something like 30% of the world's population carries in their GI, has become an infectious problem (Cdiff infection, or CDI) in the last 15 years because of the following process: First, a patient takes life saving antibiotics for a medical problem. Without antibiotics something like 60% of infections are fatal (the bad old days before penicillin was discovered). Those antibiotics wipe out the infection, but also the good GI bacteria, but Cdiff is able to make an impervious spore form that is immune to all known antibiotics except for Metronidazole and Vancomycin (which are both not normally given for infections, Vancomycin especially has some very nasty side effects). Once the patient is better and they discontinue antibiotics, the Cdiff can flourish in the absence of other bacteria. It produces some very nasty toxins, one that destroys cells as well as a systemic poison that can kill you (toxin A and B).
The new discovery is that it is not just the absence of healthy bacteria in the GI that triggers CDI, but the presence of this food additive Trehalose that was previously thought to be safe, because the body doesn't absorb it very well (though it does get absorbed): "Trehalose is nutritionally equivalent to glucose, because it is rapidly broken down into glucose by the enzyme trehalase, which is present in the brush border of the intestinal mucosa of omnivores (including humans) and herbivores." https://en.wikipedia.org/wiki/...
The bottom line is now that we know that Trehalose is a aggravating risk factor for CDI, any foods that contain it should be required to carry a large warning label on the front of the package (like cigarettes) describing the danger, if it is not banned altogether as a food additive. At the same time, the companies that are profiting from the manufacture and sale of Trehalose are looking at a serious lawsuit, since about 50,000 people in the US alone have died from Cdiff in the last 10 years.
There will be no human trials, other than to ban Trehalose for patients during and for a month after treatment with antibiotics (typical incidence time frame for CDI). If the cases of Cdiff drop precipitously, especially in high risk patients, that will be all the confirmation required.

You now have a democrat senator, in Alabama, of all states. Get over it.
having just caught c diff during a hospital stay where the food was absolutely disgusting, it doesn't surprise me one bit that food additives are allowing bugs to thrive. i've never heard of trehalose, but it makes me wonder if more popular sweeteners are at fault too.
hospital blamed me for the problem, but the hospital is well known for issues with outbreaks and their cleaning procedures. as in they have none. this hospital is like dr nick riviera's discount health center.
Scientist try to make bug resistant plants, jack around with DNA to stop this or that in NATURE. Oh, but it's 100% safe. Yeah, right. Granted, the over prescription of antibiotics in the 80's was a mess, but that isn't the only reason. I for one, am very fortunate...the number of times I've had to use just plain old run of the mill antibiotics you can count on one hand. My younger sister on the other hand, has to have those really jacked up price kind to do her any good.
Many parts of Alabama have been traditionally Democrat. Particularly back when there was such a thing as conservative Democrats. The remainder of many such conservative Democrats switched over to the Republican party during Clinton years. I'll also note that Alabama had a Democrat governor not long ago, until he was targeted by Bush/Cheney/etc and hit with corruption charges.
