Study helps explain how xanthan gum, a common food additive,

If you are a reader of foods labels, you have probable encountered an component called xanthan gum in every thing from yogurt to baked products to salad dressing. Xanthan gum is commonly extra to processed food items, food items that have been altered from their purely natural condition and which make up almost 70 per cent of the regular U.S. eating plan. It is often used as a thickener due to its exceptional capability to make liquids a lot more viscous.

A new study led by Matthew Ostrowski, Ph.D. and Eric Martens, Ph.D. of the College of Michigan Professional medical Faculty Office of Microbiology and Immunology, and Sabina Leanti La Rosa, Ph.D. and Phillip Pope, Ph.D. of the Norwegian College of Life Sciences, examines the means of the human gut microbiome to digest this relatively just lately launched foodstuff component.

Xanthan gum processing appears to be driven by a single microbe, a bacterium from the family Ruminococcaceae, which breaks down the carbs in xanthan gum. A diverse intestine bacterium, Bacteroides intestinalis, feeds on the smaller sized carbs produced by the Ruminococcaceae bacterium. Bacterial consumption of xanthan gum very likely potential customers to the creation of shorter-chain fatty acids that perform roles in intestinal health and can contribute to whole caloric consumption.

Also, the genetic signatures of these intestine microorganisms are rather absent in samples from microbiomes of men and women from non-industrialized nations around the world, hinting that common usage of the foodstuff additive may well actively change the gut microbiome. The group also found that mice microbiomes are in a position to process xanthan gum, which may possibly suggest that the capability to process the substance may possibly have currently been current in the mammalian gut to some degree.

Ostrowski states, “Whilst xanthan gum is generally thought of secure, our effects recommend that its widespread consumption may be enriching our microbiomes for bacteria that take in it. Our analyze is the first action in comprehension how new foodstuff substances could be shifting our microbiomes and whether these changes are great or poor. This might be specifically significant for people today who take in over-common quantities of xanthan gum, this sort of as people with celiac disorder and those adhering to gluten-free weight loss plans.”
