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. There is no correlation with importation of trehalose and correlation of epidemic strains of C. diff. [7], At least three biological pathways support trehalose biosynthesis. Understanding Trehalose Labeling: What Is Trehalose And Why Trehalose This can occur at lower consumption amounts in a very small percentage of the population having a trehalase deficiency. Do foods labeled "non-GMO" only (and not "organic") have more pesticides in them? International and National Authorities Confirm, Approvals of Trehalose Manufactured Using. 2019). The American Heart Association suggests limiting all added sugars to 9 tsp. The US Food and Drugs Agency (FDA) labeled trehalose as GRAS (generally recognized as safe) when added to dietary products [48, 49]. This is unlike ribotype-027 strains, which all appear to have the mutation.

Fermented products including beer and wine contain trehalose. U.S. FDA issued No question letter to GRAS determination (GRN No. Trehalose is a sugar which, on a cellular level, appears to have therapeutic mechanisms by regulating protein unfolding. Then, the level of trehalase remained constant in the intestine throughout life. These strains thrived on trehalose and produced much more toxins [52, 53]. [26] Fifth, trehalose phosphorylase (TreP) either hydrolyses trehalose into glucose-1-phosphate and glucose or may act reversibly in certain species. 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. [24] Third, the TreY-TreZ pathway in some bacteria converts starch that contain maltooligosaccharide or glycogen directly into trehalose. (25 g) for women [51]. The serving size on the label is based on the amount of food that people may typically eat at one time and is not a recommendation of how much to eat. Trehalose manufactured using enzymatic technology is also approved in Australia/NZ (FSANZ), Brazil (ANVISA), Canada (Health Canada), China (MOH), India (FSSAI), and is allowed for use in food products in over 60 countries as of 2021.
