Glyphosate disrupts gut microbiome – even at “safe” doses

Glyphosate, the key ingredient in Bayer AG’s weed-killer Roundup, is the most commonly used herbicide in the United States. Although its effects on wildlife and the environment are well-documented, its impact on humans remains controversial. But that may soon change, thanks to a recent study by a team of European researchers. Published in the journal Environmental Health Perspectives, it showed that exposure … Continue reading Glyphosate disrupts gut microbiome – even at “safe” doses

Gut bacteria can help fight the harmful effects of processed foods like cereals and pasta, scientists find

Research shows how a certain bacterium found in the human gut can break down a chemical commonly found in processed foods, such as ultra-pasteurized milk, pasta, chocolate and breakfast cereals. Published in Cell Host & Microbe, the findings generate invaluable insight into how gut microbes break down processed foods and lower the risk of health conditions often associated with those foods, such as … Continue reading Gut bacteria can help fight the harmful effects of processed foods like cereals and pasta, scientists find

Testing for a commensal gut bacterium could help identify people at risk of severe COVID-19

A new study suggests that the composition of gut microbiota could help predict COVID-19 severity. Researchers at the University of Massachusetts Medical School (UMMS) examined stool samples from COVID-19 patients and found that those who were critically ill had altered gut microbiomes. The researchers also identified a commensal bacterium called Enterococcus faecalis as a strong predictor of COVID-19 severity. E. faecalis is a symbiont with a potential to … Continue reading Testing for a commensal gut bacterium could help identify people at risk of severe COVID-19

Researchers say taurine trains your gut microbiota to resist subsequent infections with the same pathogen

Your gut microbiota helps shield you from infections, and for the longest time, scientists have wondered how. A new study published on Jan. 15 in the journal Cell details the process involved in gut immunity, or specifically, how your gut microflora functions to give you colonization resistance. Using mouse models, a team from the National Institutes of Health (NIH) identified which bacteria help your body … Continue reading Researchers say taurine trains your gut microbiota to resist subsequent infections with the same pathogen

Can abdominal pain affect brain function?

Brief pain is something your brain and body can handle with ease. But chronic pain, especially if it is originating from the abdomen, is an entirely different story. Chronic abdominal pain can have complex and lasting effects on your brain. It changes how the brain responds to pain signals. Eva Szigethy, a professor of psychiatry and medicine and the … Continue reading Can abdominal pain affect brain function?

Gut microbiota has a key role in mechanisms associated with muscle strength among the elderly

Researchers from Tufts University and the Harvard Medical School found that the gut microbiota may be involved in mechanisms affecting muscle strength in the elderly. The team examined healthy and unhealthy older adults and found that the two groups have a distinct profile of gut bacteria. Further experiments with mice demonstrated a link between the gut microbiota and muscle strength. … Continue reading Gut microbiota has a key role in mechanisms associated with muscle strength among the elderly

Study: Taking common drugs linked to impaired microbiome health and increased risk of obesity and intestinal infections

Researchers from the University Medical Center Groningen and Maastricht University Medical Center in the Netherlands have found that 18 common drug categories can negatively impact the gut microbiome, the total population of microbes present in the gut and their collective genetic material. Many of these drugs, such as the diabetes drug metformin and the antidepressant selective serotonin reuptake inhibitors (SSRIs), can disrupt … Continue reading Study: Taking common drugs linked to impaired microbiome health and increased risk of obesity and intestinal infections

Researchers investigate green tea compounds that may help resolve antibiotic resistance

Scientists have reported that compounds present in green tea may improve the efficacy of antibiotics against antibiotic-resistant bacteria. In their report, researchers from the University of Surrey‘s School of Veterinary Medicine in the U.K. noted this effect is because of the compound epigallocatechin gallate (EGCG), which is present in green tea. EGCG is a plant compound with potent antioxidant properties. This means that … Continue reading Researchers investigate green tea compounds that may help resolve antibiotic resistance

The ketogenic diet helps reduce epileptic seizures through its effects on gut microbiota

The ketogenic diet is one of the oldest forms of medical treatment for epilepsy in infants and children. But the mechanisms underlying its anti-seizure effects have remained unclear until recently. In a recent study, researchers from the University of California, Los Angeles (UCLA) found that certain bacteria in the gut play an important role in mediating the anti-seizure effects … Continue reading The ketogenic diet helps reduce epileptic seizures through its effects on gut microbiota

Auto-brewery syndrome – when gut bacteria produce too much alcohol – may cause fatty liver disease

Some microorganisms can raise a person’s blood alcohol to dangerously high levels, even if he hasn’t touched a drop of alcohol his whole life. In a study published in the journal Cell Metabolism, certain types of gut bacteria can ferment carbohydrates into alcohol within the body — a condition known as auto-brewery syndrome (ABS). A team of researchers from the Capital Institute of Pediatrics in … Continue reading Auto-brewery syndrome – when gut bacteria produce too much alcohol – may cause fatty liver disease
