chewing gum microbiome

According to the researchers, it is a new untapped source of ancient DNA. La mastication continue de chewing-gum peut entraîner une augmentation du niveau de stress pour l’estomac et les intestins. Introduction Xylitol, a naturally occurring five-carbon polyol (sugar alcohol), is used in several products, including chewing gum, as a sugar substitute; it has been shown to have beneficial effects in the maintenance of oral health. © 2021 Scientific American, a Division of Springer Nature America, Inc. Support our award-winning coverage of advances in science & technology. Conclusions: This study has shown that chewing gum containing maltitol had minor effects on the composition of the plaque microbiome. Behind them, the woman and her kin built weirs to trap fish that they skewered with bone-tipped spears. Effects - Helps to maintain the mineralisation of the teeth and to fight against dental plaque - Helps reduce dry mouth that causes bad breath - Contributes to the maintenance of normal dentition. The Syltholm birch tar sample—along with the genomic information concealed in it—was likely so well-preserved because it was buried in an oxygen-free environment, says Natalija Kashuba, an archaeologist at Uppsala University in Sweden and lead author of the paper published in May. Weyrich says the study could herald a new chapter in studying ancient people’s—and their microbiome’s—evolution. In any case, when she discarded the tar, it was sealed away under layers of sand and silt for some 5,700 years until a team of archaeologists found it. Après les repas, votre estomac doit bénéficier d’une période de repos pour digérer les aliments, mais la mastication et l’ingestion continue de salive interfèrent avec ce repos. Nous avons trouvé des bactéries qui peuvent être utilisées pour nettoyer les chewing-gums, car elles les mangent!

Or she might have simply been enjoying what amounted to Neolithic chewing gum. When you chew gum, your saliva becomes more alkaline, and because of the additional saliva production that happens while you chew, it causes you to swallow more often, … Ancient “Chewing Gum” Reveals a 5,700-Year-Old Microbiome. Chewing gum could be a vector of bacterial diseases quite long after being thrown to the ground. Saliva samples were collected at baseline and from 0 to 2, 2 to 5, 5 to 10, 10 to 15, and … Le chewing-gum est également à l’origine de migraines et de maux de têtes violents chez les enfants et les adolescents. Ancient “Chewing Gum” Reveals a 5,700-Year-Old Microbiome. According to Schroeder and his colleagues, the Syltholm woman’s genome indicates she was not related to communities of farmers that did live in Denmark around the same time. Twenty healthy young adults were randomly instructed to chew either PE gum or placebo gum. Written by TE in Global, Nature. Co-lead study author Theis Jensen, a bioarchaeologist at the University of Copenhagen, initially hit upon the idea of extracting genomic data from birch while he was working at a different dig site in Sweden and began to see pieces of tar with teeth imprints in them. The village, dubbed Syltholm by modern archaeologists, was near a coastal lagoon that was protected from the Baltic Sea by sandy barrier islands. She was descended from a genetic group archaeologists refer to as Western hunter-gatherers, who began settling in Scandinavia via a southern route as early as 11,700 years ago. Could gum help prevent cavities in the same way as tooth brushing or flossing? Et l’analyse des restes du microbiome oral préservés dans ce vieux chewing-gum a pu offrir un instantané de sa vie. A practical format to take everywhere, to be taken after a meal. The woman may have worked the tar until it was pliable enough to repair a piece of pottery or a polished flint tool—birch tar was a common Stone Age adhesive. Stone Age “Chewing Gum” Yields 5,700-year-old Human Genome and Oral Microbiome Thousands of years ago in what is now Denmark a young Neolithic woman chewed on a birch pitch.DNA analysis of this prehistoric “chewing gum” has now revealed, in remarkable detail, what she looked like. Chewing gum has been suggested to have many cognitive benefits such as increasing focus and alertness, improving memory, and controlling, besides its obvious benefit of making breath smell minty fresh. Menu. bioRxiv. Researchers have succeeded in extracting a complete human genome from a thousands-of-years old 'chewing gum.' The gum had traces of DNA from hazelnut (Corylus avellana) and mallard (Anas platyrhynchos), which the woman may have recently eaten and which could have been staples in a hunter-gatherer’s diet. Nederlands. La lumière du soleil est-elle suffisante pour un statut suffisant en vitamine D chez les enfants et les adolescents? Chewing gum has also been shown to have beneficial effects in the prevention of dental caries by increasing the flow of saliva (Dodds, 2012). Each chewing gum provides 100% of the recommended fluoride and vitamin D content. Ancient “Chewing Gum” Reveals a 5,700-Year-Old Microbiome December 17, 2019 102 Toward the end of the Stone Age, in a small fishing village in southern Denmark, a dark-skinned woman with brown hair and piercing blue eyes chewed on a sticky piece of hardened birch tar. “We have this inconspicuous little lump of birch pitch that someone discarded thousands of years ago, and suddenly we’re able to conjure up this person from it,” says Hannes Schroeder, an archaeologist at the University of Copenhagen and the paper’s corresponding author. Effects of short-term xylitol gum chewing on the oral microbiome. Dans cette étude interventionnelle, un essai contrôlé randomisé a été utilisé pour évaluer les effets à court terme du chewing-gum contenant du xylitol sur le microbiote salivaire. Schroeder and his colleagues identified a host of microbial taxa from the sample, some of which were part of the community of microbes that live, often harmlessly, in and on humans called the microbiome. The ancient chewing gum acted as a time capsule, storing information about her oral microbiome, the bacteria that lived in her mouth, as well. Votre adresse de messagerie ne sera pas publiée. The researchers also discovered the woman carried Epstein-Barr virus—a very common member of the herpesvirus family—and several strains of virus responsible for pneumonia.
