Gut Bacteria

Byproducts from gut bacteria breaking down tryptophan, a dietary amino acid, can restore hormone-secreting gut cells reduced by obesity, a new study found. It opens the door to a natural, side-effect-free alternative to GLP-1 drugs like Ozempic.

The human body is teeming with microbes, especially in the gut. To coexist smoothly, our bodies need to know what these tiny residents are up to. But can our bodies sense gut microbe activity in real-time and shift behavior accordingly?

While it's estimated that millions worldwide suffer from chronic fatigue syndrome, a test for the condition still doesn't exist. That could be set to change with the release of a new study that finds the condition's fingerprint in the gut microbiome.

Your gut bacteria might give away more about you than your accent does. In a new study, scientists used people’s microbiome to predict where they lived, down to the city, with 94% accuracy. It gives new meaning to the phrase "you are what you eat."

A groundbreaking study has revealed that white sugar doesn’t just feed bacteria in the gut – it rewires them. Consuming sugar can trigger physical flips in bacterial DNA, setting off a chain reaction that alters immune responses and gut health.

A new study published in Nature Microbiology has reported a naturally occurring family of bacterial species in the human gut that can absorb and break down toxic, long-lasting "forever chemicals" and carry them out as waste through feces.

Alternating between a calorie-restricted plan and one high in fat and sugar, resulting in weight gain, is not just down to psychology and behavior. This kind of weight-loss-gain cycle – yo-yo dieting – has a surprising biological driver: The gut.

A small daily dose of kombucha made from black tea has been shown to meaningfully reshape the gut microbiome in adults – particularly those with obesity – without any dietary changes. It also reveals a lot about the importance of micro-biodiversity.

A new study has found that diet-driven weight gain triggers impaired cognitive functioning an symptoms of anxiety, adding to the growing body of evidence that there's an intrinsic biological link between our gut health and our mental health.

A large-scale human clinical trials is currently underway testing a wild idea. Can fecal transplants reduce a person's cravings for alcohol by altering their microbiome? Early studies are indicating this could be possible.

A new AI model can predict the likelihood of premature death from inflammatory bowel disease, with 95% accuracy. This is good news – by looking beyond the gut for early treatment of other chronic illnesses can greatly reduce the early mortality rate.

There could be new hope for people afflicted with the skin-discoloring disease, vitiligo. A new treatment reportedly works great on mice with the malady, and it utilizes a natural substance produced by beneficial gut bacteria.
