Sugar Additive Trehalose Could Have Helped Spread Dangerous Superbug Around the US (sciencealert.com) 78

A sugar additive used in several foods could have helped spread a seriously dangerous superbug around the US, according to a 2018 study. ScienceAlert reports: The finger of blame is pointed squarely at the sugar trehalose, found in foods such as nutrition bars and chewing gum. If the findings are confirmed, it's a stark warning that even apparently harmless additives have the potential to cause health issues when introduced to our food supply. In this case, trehalose is being linked with the rise of two strains of the bacterium Clostridium difficile, capable of causing diarrhea, colitis, organ failure, and even death. The swift rise of the antibiotic-resistant bug has become a huge problem for hospitals in recent years, and the timing matches up with the arrival of trehalose.

"In 2000, trehalose was approved as a food additive in the United States for a number of foods from sushi and vegetables to ice cream," said one of the researchers, Robert Britton from the Baylor College of Medicine in Texas, back in January 2018. "About three years later the reports of outbreaks with these lineages started to increase. Other factors may also contribute, but we think that trehalose is a key trigger."

The C. difficile lineages Britton is referring to are RT027 and RT078. When the researchers analysed the genomes of these two strains, they found DNA sequences that enabled them to feed off low doses of trehalose sugar very efficiently. In fact, these particular bacteria need about 1,000 times less trehalose to live off than other varieties of C. difficile, thanks to their genetic make-up. [...] It's still not certain that trehalose has contributed to the rise of C. difficile, but the study results and the timing of its approval as an additive are pretty compelling. More research will now be needed to confirm the link.
According to figures from the CDC, "C. difficile was responsible for half a million infections across the year and 29,000 deaths within the first 30 days of diagnosis," adds ScienceAlert.

The findings were published in the journal Nature.

    This is a reprint from a 2018 post, and in 2019 follow up research in a validated gut model showed that it didn't appear to increase virulence: https://www.ncbi.nlm.nih.gov/p... [nih.gov] The earlier research this points to is largely correlative, but does not show causation. The follow up research was looking at seeing if it was actually causative. It's not like one study alone can conclude anything absolutely, but it's a fairly damaging study to the hypothesis. I found this info from the Wikipedia article on Trehalose: https://en.wikipedia.org/wiki/... [wikipedia.org]

      Worse even, note the exact date - 02 January 2018. In three days it will be a full four years old.

      ScienceAlert seems to have very loose definition of what constitutes an "alert". Maybe the journalist is phoning this in while on holiday (it is dated 30 December 2021).

    It's not clear that they have demonstrated cause and effect. There are many strains of C.difficile and they have all been troublesome for some time, mainly in the sick and infirm. While trehalose may have allowed two particular strains of C.difficile to predominate, are they any worse than the strains they have replaced?

      Ultimately, it's down to the effect on the gut microbiome (since it's the gut and gut effects that are involved). If something reduces the microbiome, or leads to harmful mutations, then you're going to have a breeding ground for harmful bacteria. If something increases the microbiome (within limits), particularly if it leads to benign mutations, then you're going to have protection from harmful bacteria.

      That's pretty much the key mechanism.

    I had read about trehalose being a zero calorie sweetener as well as a potent antioxidant. It displaces water, but unlike glucose it prevents oxidation, so I planned to make some extra fresh tasting fruit preserves by osmotically replacing the water at room temperature. I bought some and tried it in tea just to get a sense of how sweet it would be and see if it had any negative GI effects. Ooohhhh boy did I regret it. I wasn't sure what was wrong, but I never thought about using it for food-anything ever again. I've read most people have some small percentage of their gut microbe that is C. Diff., so given this article I presume I gave mine just what it needed. -_-

    Microbiome researchers have recently identified how lots of sugar in the gut damages the surfaces of the GI tract and leads to inflamed & bleeding tissues, giving rise to the ability of microbes in the GI tract to migrate into the blood stream and consequently into organs in the body.

    High Fructose Corn Syrup is now in nearly every "natural" sugar added product from restaurant meals, to drinks, snacks and baked goods. It appears to be linked the rise in obesity since its introduction in around 1980.

    Refined sugar intake &/or sugar intake in high quantities looks to be a true self-induced poison, yet people in general know about it but don't do anything to reduce their intake.

    Average consumption of sugar 2 centuries ago was a few pounds a year at most, and today it is many dozens of pounds per year & some people are in the 100 pounds or more per year category.

    Given the obvious damage, I dare say sugar is worse than Covid. Oh-Oh, now I said something controversial. We are within 10% points of having half of all adults in the US being obese. That ought to be a major warning.

    • So, how do you explain the obesity epidemic in countries other than the US, who don't tend to use high fructose corn syrup at all?

      Aussie here, we use cane sugar for sweeteners.

      And our bread is not sweet.

      Full disclosure, I'm overweight, but I blame that on the evil bourbon your country keeps pouring down my throat!! :(

        Seed oils are another evil foisted on us by believe it or not, Procter and gamble with the invention of crisco. Seed oils and sugars, whether from cane, fruit juice or corn should all be minimised.
        Bourbon is health drink, as it dissolves the fat deposits in your arteries!

        • I'm not familiar with 'crisco', is this another US only thing? What is it?

          I use olive oil (extra virgin, so crushed, no heat, no chemicals, if it's really EVOO) and peanut oil for my cooking.

          Bourbon dissolves fat in my arteries? Ha ha, yeah, sure, then it deposits said fat in my abdominal cavity, so... ?? :(

            The main seed based oil used here in the UK is rapeseed which is generally considered good for you. The idea that olive oil is bad for you must be news to those with a Mediterranean diet who generally have better life expectancy than their northern European counterparts.

            According to Wikipedia "crisco" was originally hydrogenated cottonseed oil and stuffed full of trans fatty acids. It's not clear what it is now.

            To be fair food standards in the USA are way lower than in Europe.

            • For reasons, I prefer "canola" to "rapeseed", knowing too many women who may dislike the name.

              Though a quick glance at Wikipedia tells me that the etymology is quite safe:

              "The name for rapeseed comes from the Latin word rapum meaning turnip. Turnip, rutabaga (swede), cabbage, Brussels sprouts, and mustard are related to rapeseed. Rapeseed belongs to the genus Brassica. Brassica oilseed varieties are some of the oldest plants cultivated by humanity, with documentation of its use in India 4,000 years ago, and

    • The War on Fats [time.com] was a mistake and we're slow to own up to it. It's a lot like that line from Serenity: "They'll swing back to the belief that they can make people... better".

    Of course, trehalose is not the only major change that happened at the turn of the century. Clearly the fall of the twin towers in 2001 led to the oiutbreaks in 2003. The timing fits, doesn't it? The year 2000 also saw the launch of DeviantArt and a major solar flare. It's only logical that these three factors conspired with trelahose to promote Clostridium difficile, and that this was all part of a lizard people scheme to test the reactions of health institutions before the launch of COVID-19. /sarcasm
