What Are Prebiotics And How Do They Work?

And how do #prebiotics differ from #probiotics? Experts weigh in on how these trendy supplements may influence your well-being. #microbiota #microbiome #bacteria #prebiotic #probiotic Browse the aisles of any health food store or drugstore, and you’re likely to find prebiotic supplements. They’re packaged as powders, gummies, pills and drinks and claim to improve digestion, boost the immune system, lower blood sugar and more. According to Grand View Research, a market researc

Eating specially-colored muffins could reveal whether you have inflammatory bowel disease

Eating blue muffins can reveal health of gut #microbiome. Eating a muffin dyed blue could reveal your gut transit time, which may help diagnose your gut health & act as an early warning. Gut transit times varied from ~ 12 hrs to > 72 hrs in a study. #microbiota #health If you ever wanted an excuse to bake a bunch of muffins, you're in luck... just make sure they're blue. Experts believe eating the specially-coloured treats may provide a warning sign of poor gut health. If th

Do oral bacteria play a role in hypertension?

Researchers found an association between the oral #microbiota and the risk of #hypertension in people who have experienced menopause. Specific bacteria were associated with both baseline blood pressure and the risk of developing hypertension. #oralhealth #heart #heartdisease #microbiology #microbiome Almost half of adults in the United States have high blood pressure, or hypertension. People with hypertension have an increased risk of stroke and heart disease. The researchers

Review on association of fungi with development and progression of carcinogenesis in the human body

Highlights •Long-term #Candida infection contributes to #oralcancer development. •Candida species contribute to tumor induction along the gastrointestinal tract through production of carcinogenic nitrosamines. •Voriconazole is involved in the development of squamous cell carcinoma in lung transplant patients. #cancer #mycobiota #microbiota #microbiome #oralhealth Abstract The role and impact of commensal and pathogenic fungi in different parts of the human body are being inc

Fermented foods show potential in increasing gut microbial diversity and modulating immune responses

Fermented foods, such as #yogurt, #kefir, #kimchi & #kombucha, have gained increasing popularity on the market shelves. Scientists elucidate how fermented foods may alter gut #microbiota profile & reduce #inflammation. During the past decade, a thriving scientific interest has been raised in exploring the gut microbiome of non-westernized populations. The growing realization of the fundamental role that urbanization is playing in human health and disease, especially in non-c

Microbiome Likely Not a Causal Factor for Autism, Suggests Largest Study

A new study challenges the idea that #autism spectrum disorder (#ASD) may be causally influenced by childhood gut #microbiota. The study suggests the reverse is true – a restricted #diet in autism may instead alter the gut microbiota.

Research examines whether genetic traits are the cause of periodontitis

Research examines whether genetic traits cause periodontitis. The oral #microbiota of participants with #periodontitis were different & more diverse than healthy controls. One factor wasn’t associated with gum disease at all: host genetic polymorphism. Nearly 10 percent of the world’s population suffer from severe gum disease, or periodontitis, according to the World Health Organization. Could genetic variations be to blame? A recently published study set out to determine whe

Characterization of the Blood Microbiota in Children with Celiac Disease

#Microbiota #CeliacDisease #Microbiome #Children #Pedriatic Highlights •Bacteroidetes is most abundant phylum in pediatric blood •Beta diversity is increased in blood of children with active celiac •Abundance of taxa are altered in blood of children with active celiac Abstract Celiac Disease (CD) is an autoimmune disorder triggered by gluten ingestion that can develop in genetically predisposed individuals. Alterations in the gut microbiota have been suggested to contribute

This mushroom might alter gut bacteria for the better, study finds. #Ganoderma #Reishi #Lingzhi #obesity #diabetes #insulin #microbiota #microbiome #芝草 A mushroom a day may keep the doctor away. The active ingredients in a Asian mushroom can change bacteria in your stomach for the better, researchers have found. By altering gut bacteria, the Reishi mushroom (Ganoderma lucidum) prevents and reverses symptoms of obesity in mice, including weight gain and insulin resistance. “Mi

New Research Discovers Potential of Gut Microbes To Reverse Aging in the Brain

New study shows that it's possible to reverse aspects of #aging-related deterioration in the #brain and cognitive function via the the gut #microbiota from young mice Research from APC Microbiome Ireland (APC) at University College Cork (UCC) published on August 9, 2021, in the leading international scientific journal Nature Aging introduces a novel approach to reverse aspects of aging-related deterioration in the brain and cognitive function via the microbes in the gut. As o

Antibiotics in Early Life Could Lead to Brain Disorders

Exposure to #antibiotics in utero or after birth could lead to brain disorders in later childhood, says Rutgers researcher. #microbiome #microbiota Antibiotic exposure early in life could alter human brain development in areas responsible for cognitive and emotional functions, according to a Rutgers researcher. The laboratory study, published in the journal iScience, suggests that penicillin changes the microbiome — the trillions of beneficial microorganisms that live in and

Centenarians have a distinct microbiome that may help support longevity

A study found that centenarians, compared to younger people, have higher levels of several bacterial species that produce secondary bile acids, which are thought to help protect the intestines from pathogens & regulate the body's immune responses. #microbiome #microbiota #aging Centenarians are less susceptible to age-related chronic diseases and more likely to survive infectious diseases. Now, a new study reveals that people who live to be 100 or older have a unique microbio

Babies at risk for diabetes may have microbiota restored

Newborns at risk for Type 1 #diabetes because they were given antibiotics may have their gut microorganisms restored with a maternal fecal transplant, according to a new study. #microbiota #microbiome The study, which involved genetic analysis of mice, appears in the journal Cell Host & Microbe. The findings suggest that newborns at risk for Type 1 diabetes because their microbiome—the trillions of beneficial microorganisms in and on our bodies—were disturbed can have the con

You’re Missing Microbes. But Is ‘Rewilding’ the Way to Get Them Back?

The science behind the idea of restoring the intestinal #microbiome to an ancestral state is shaky, skeptics say, and in some cases unethical. #microbiology #microbiota As the sun set in Tanzania on a September evening in 2014, Jeff Leach inserted a turkey baster filled with another man’s feces into his rectum and squeezed the bulb. The feces, he said, came from a hunter-gatherer who was a member of the Hadza people and lived nearby. Mr. Leach said he was trying to “rewild” h

With age, insufficient tryptophan alters gut microbiota, increases inflammation

With #aging, a diet lacking in the essential amino acid #tryptophan -- which has a key role in our mood, energy level and immune response -- makes the gut #microbiome less protective and increases #inflammation body-wide, investigators report. In a normally reciprocal relationship that appears to go awry with age, sufficient tryptophan, which we consume in foods like milk, turkey, chicken and oats, helps keep our #microbiota healthy. A healthy microbiota in turn helps ensure

Cause or effect? The spatial organization of pathogens and the gut microbiota in disease

#microbiota #microbiome #immunology #microbiology The human gut hosts a dense and diverse microbial community, spatially organized by multiple scales of structure. Here, we review how microbial organization differs between health and disease. We describe how changes in spatial organization may induce alterations in gut homeostasis, concluding with a future outlook to reveal causality. Free article.
