Connect two glucose molecules, and you get a food additive that offers surprising health benefits. It's called trehalose, and even though its presence in the food chain is nothing new, the amount of it in processed foods is. Except where otherwise noted, data are given for materials in their standard state (at 25 C [77 F], 100 kPa). ?) Trehalose (from Turkish ' tgala ' a sugar derived from insect cocoons + -ose) is a sugar consisting of two molecules of glucose. As youre about to see in Dangers and Side Effects, its impact on gut bacteria may have a dark side. [7], At least three biological pathways support trehalose biosynthesis. Find the summary of the lecture 'Trehalose is not associated with the emergence and spread of epidemic Clostridium difficile strains' here. WebHow Is Trehalose Listed On Food Labels? A study by Baylor College of Medicine in Houston found that ingesting trehalose revved up two strains of C-diff "by more than 500-fold," making the bacterium hypervirulent. These studies provided a range of low trehalase activity from 0% to a maximum of 2%. Approved as a novel food ingredient in Brazil. ), a germ that causes dangerous, hard-to-treat gut infections. Isotrehalose is also yet to be isolated from a living organism, but was found in starch hydroisolates. A study recently published in Nature suggests the use of trehalose as a food additive may have triggered the uncontrolled growth of aggressive, antibiotic-resistant superbugs [52]. How to determine that a particular product is Organic? Trehalose is a naturally occurring glucose found notably in mushrooms (shiitake, maitake, nameko), sunflower seeds, sea algae, and yeast (bakers, wine). claimed, by reviewing the genetic code of over 10,000 strains of C. diff for the trehalose metabolizing variant/mutation. The digestion and absorption of trehalose in humans is similar to that of other disaccharides. It occurs naturally in foods such as mushrooms, honey, shrimp, yeast, and soybeans. 2019). Webhow is trehalose listed on food labels how is trehalose listed on food labels. WebTrehalose definition, a white, crystalline disaccharide, C12H22O11, occurring in yeast, certain fungi, etc., and used to identify certain bacteria. Clostridium difficile causes a type of hospital-acquired infection that is characterized by diarrhea and inflammation of the colon. WebTrehalose activates autophagy through the activation of Transcription Factor EB (TFEB), a key factor in lysosomal and autophagy gene expression. Safety studies found no adverse effects of trehalose in adults, children, and pregnant women. [12], The two prevalent theories as to how trehalose works within the organism in the state of cryptobiosis are the vitrification theory, a state that prevents ice formation, or the water displacement theory, whereby water is replaced by trehalose.[11][14]. However, recent findings exposed it as a potential culprit of dangerous C. difficile outbreaks. The bonding makes trehalose very resistant to acid hydrolysis, and therefore is stable in solution at high temperatures, even under acidic conditions. A very small portion of the population may have impaired digestion of trehalose, but this is very uncommon. More research will be needed to confirm the link. Buckley A.M., Moura I.B., Arai N., Spittal W., Clark E., Nishida Y., Harris H.C., Bentley K., Davis G., Wang D., Mitra S., Higashiyama T., Wilcox M.H. To stay on the safe side, avoid trehalose if you have any digestive issues, especially hospital-acquired gut infections. Will it be called "trehalose", or some E-number, or something else? Our goal is to not have a single piece of inaccurate information on this website. [citation needed] Trehalase genes are found in tardigrades, the microscopic ecdysozoans found worldwide in diverse extreme environments. His mission is to bridge the gap between science and everyday life, helping readers improve their health and feel better. Hayashibara Co., Ltd., (Hayashibara) manufactures a trehalose product from starch using enzymatic technology and sells it in many countries under the tradename of TREHA. Support small. Our science team must pass long technical science tests, difficult logical reasoning and reading comprehension tests. Skin care products, quick-dissolving tablets, and some advanced biological drugs also contain trehalose [6, 7, 8, 9]. Read on to learn all the perks and dangers of trehalose. The science around nutrition and food often requires an expert to interpret. This site is dedicated to helping Trehalose binds water, prevents oxidation, and preserves the structure of food during freezing and heating. This is especially important for people susceptible to C. difficile infections. suggests correlation between the increasing importation of synthetic trehalose with a rise in C. diff infection, claiming that the widespread adoption and use of trehalose in the diet coincides with the emergence of both ribotype-027 and 078 outbreaks. [26] Fifth, trehalose phosphorylase (TreP) either hydrolyses trehalose into glucose-1-phosphate and glucose or may act reversibly in certain species. They are spread through lots of different types of C. diff, not just epidemic types. Aleksa is passionate about herbal pharmacy, nutrition, and functional medicine. [11], Trehalose is the major carbohydrate energy storage molecule used by insects for flight. Can I tell police to wait and call a lawyer when served with a search warrant? Saund K., Rao K., Young V.B., Snitkin E.S. It does show that the resistant strains of C. difficile can grow in vitro on low doses of trehalose, but they metabolize and flourish on several other carbon sources as well (and, as noted, none were directly compared to trehalose). These results are not surprising. Asking for help, clarification, or responding to other answers. It is important to know that correlation does not equal causation, and in fact, when you look closer at trehalose importation and virulent C. diff out breaks, they do not correlate at all. For further information on this subject please see the following URL of National Institutes of Health, U.S. Department of Health and Human Services. [23] Second, trehalose synthase (TS) in certain types of bacteria could produce trehalose by using maltose and another disaccharide with two glucose units as substrates. Interestingly, the findings indicated that several carbohydrates and amino acids (not just trehalose) caused a 1.5-fold increase in the virulent strains. 1995). That is, trehalose contains an ,-1,1 glycosidic bond, while maltose contains an -1,4 glycosidic bond. Additional factors that differentiate the two glucose containing disaccharides include the fact that maltose is a reducing sugar, whereas trehalose is not, and trehalose is significantly more stable than maltose under high temperatures and acidic pH (Richards et al.2002). The Food and Drug Administration lists it as "Generally Recognized As Safe" (GRAS). A better, more equitable comparison would have been another sugar (or more than one sugar), particularly one that has been shown in previous experiments to stimulate the growth of C. difficile. rackandboneman Jan 15, 2018 at 19:02 Looking online at the ingredients in UK supermarket sushi, I see "sugar" added to the rice, but no mention of trehalose. This effectively prevented cell mutations and protected healthy cells against UV damage. Outbreaks [52]: In light of the available evidence, trehalose as an added sugar seems to be safe for most healthy people in recommended amounts. 2019 & Saund et al. Because trehalose is contained in marine plants such as hijiki seaweed, it is called seaweed sugar in China.In fact, trehalose is found in dry yeast, accounting for 12% by dry weight of bakers yeast. People with diabetes and insulin sensitivity should pay special attention to their daily sugar intake, which includes trehalose. Clinical studies would need to evaluate its effectiveness and safety as a sugar substitute in diabetic patients. People with diabetes and insulin resistance should be extra cautious. 1998;44:787-798. Trehalose induced autophagy in blood vessel cells and inhibited a virus linked to clogged blood vessels (the human cytomegalovirus or HCMV), but this doesnt tell us much about its potential effects in living organisms [34]. For example, in Canada, outbreaks of the virulent strains of C. difficile occurred some three years before the approval and expanded use trehalose. He points out that while both strains ribotype-027 and 078 existed prior to 2001, that epidemic outbreaks did not occur until 2003, and include major outbreaks in both Quebec, Canada, and Pittsburgh, USA. According to the authors of the Nature paper, this finding was the smoking gunthe conclusive evidence for the microbiological role of trehalose in the growth and proliferation of the infectious strain of C. difficile (Abbasi 2018). [citation needed], In plants, trehalose is seen in sunflower seeds, moonwort, Selaginella plants,[12] and sea algae. International and National Authorities Confirm, Approvals of Trehalose Manufactured Using. Fortified or enriched. [citation needed] One possible reason for this is that the glycosidic linkage of trehalose, when acted upon by an insect trehalase, releases two molecules of glucose, which is required for the rapid energy requirements of flight. 000045) to the U.S. Food and Drug Administration (FDA). Can trehalose be organic? Trehalose quickly found its way into processed foods in the U.S. and around the world for its mild, flavor-enhancing sweetness and protection of frozen foods. We do not aim to diagnose, treat, cure or prevent any illness or disease. (Especially in the UK.) I saw a worrying report of an article in Nature, no less, questioning whether the sugar substitute trehalose could be a cause of the recent rise in Clostridium difficile infections. 2022 Oct 6. doi: 10.1111/1541-4337.13048. Because of its unique culinary properties, it is also a highly desirable disaccharide used in a variety of food service applications to enhance freshness and flavor. The metabolism of alpha, alpha-trehalose. A plus sign next to the number [1+, 2+, etc] means that the information is found within the full scientific study rather than the abstract. But are these warnings warranted? Gudman-Hyer E., Fenger H.J., Skovbjerg H., Kern-Hansen P., Madsen P.R. In 2000, FDA approved the sugar as a safe food additive. Trehalose quickly found its way into processed foods in the U.S. and around the world for its mild, flavor-enhancing sweetness and protection of frozen foods. In some store-bought ice creams, its found at concentrations of up to 11 percent. TREHA trehalose benefits flavor systems by providing off-note masking, saltiness and citrus enhancement, and flavor stability. This high-performance ingredient can now facilitate simplified ingredient statements. TREHA trehalose is recognized as GRAS by the Flavor and Extract Manufacturers Association of the U.S. (FEMA). Your email address will not be published. The earlier experiments were done in mice, whereas ours were carried out in a model that simulates human C. diff infection. While the oft-cited association between trehalose production/utilization and C. difficile proliferation may seem compelling, other epidemiological observations suggest that factors besides trehalose consumption may be contributing to the increase in virulent strains of C. difficile (Buckley et al. 2018 & Collins et al. The only exception is in a specific closely related genetic population, native Greenlanders (Inuits). If you suspect trehalose intolerance, you may want to avoid mushrooms, seafood, dried and frozen foods. Concluded ADI not specified as a miscellaneous additive by JECFA. In a recent publication covered by the media, Collins et al. Required fields are marked *. The bonding When Hayashibara applied for approval of trehalose to international and national authorities, Hayashibara performed a literature search and reported on the portion of various populations with low trehalase activity. The authors brought up additional facts that support the potential role of trehalose in recent C. diff. Trehalose is a naturally occurring disaccharide that is readily digested in our guts. How do I connect these two faces together? This data, combined with observations that increased production and utilization of trehalose in the food supply coincided with the rise of infections caused by the virulent strains of C. difficile, led to speculation that trehalose caused the epidemic emergence of the virulent strain of C. difficile (Collins et al. Richards A.B., Krakowka S., Dexter L.B., Schmid H., Wolterbeek A.P.M., Waalkens-Berendsen D.H., Shigoyuki A., Kurimoto M. Trehalose: a review of properties, history of use and human tolerance, and results of multiple safety studies. Email your health and wellness questions to Dr. Oz and Dr. Roizen at youdocsdaily@sharecare.com. Danielson N.D., Collins J., Stothard A.I., Dong Q.Q., Kalera K., Woodruff P.J., DeBosch B.J., Britton R.A., Swarts B.M. Microbes, plants, fungi, and insects use it as a source of energy and protection against extreme conditions. [16] In humans, the only known function of trehalose is its ability to activate autophagy inducer. Sugar, Modified Anystarch, Spices and Flavourings - while they are not necessarily bad for you, they are bad for ingredient disclosure. Trehalose is a naturally occurring glucose found in mushrooms, some seaweed, lobster, shrimp and foods in which baker's or brewer's yeast is used. This effect relieved heart damage caused by insulin resistance and oxidative stress [16, 42, 39]. (25 g) for women [51]. Nonetheless, the researchers chose only to focus on trehalose, allegedly because unlike some of the other carbon sources studied, trehalose supported growth even at relatively low concentrations. Mushrooms, shrimps, and algae contain small amounts of trehalose, followed by certain seeds, honey, and baked products. Relationship between trehalose four-gene cluster presence and 30-day mortality from ribotype-15 (ST10/ST44), There was no evidence for a non-linear relationship between mortality and age using multiple fractional polynomials (, Articles on the Safety of Trehalose as it Relates to, Frontiers in Cellular and Infection Microbiology. There is no correlation between the importation of trehalose and the rate of epidemic strains of. To see whether this genetic mutation is a causal factor in increased mortality, Wilcox et al. Abbasi J. So the original claims that were made by Collins et al. Practically, its low oral absorption in its intact form paired with rapid digestion may preclude any benefits of oral intake. Expression of this enzyme in vertebrates is initially found during the gestation period that is the highest after weaning. Plus, I see that trehalose does not have an E-number, unless it's called something different there. A small percentage of people lack trehalase, an enzyme that breaks down trehalose. U.S. GRAS Notice http://wayback.archive-it.org/7993/20171031060212/https://www.fda.gov/downloads/Food/IngredientsPackagingLabeling/GRAS/NoticeInventory/UCM261213.pdf, During the 23rd Trehalose Symposium held in Tokyo on November 7, 2019, Professor Mark Wilcox of the University of Leeds (UK), gave a lecture titled Trehalose is not associated with the emergence and spread of epidemic Clostridium difficile strains and explained the contents of his co-authored paper, Clostridium difficile trehalose metabolism variants are common and not associated with adverse patient outcomes when variably present in the same lineage.
