Raw vesrus cooked diet and the gutThere have been various studies investigating the impact on the #microbiome of different kinds of diets, such as vegetarian versus meat based, but as yet none to question whether the cooking process itself alters the composition of the microbial ecosystems in our guts. Cooking involves exposing food to heat which can change the foods chemical and physical properties. Researchers from the University of California and Harvard University have set out to answer whether these alterations change the microbial environment of the #gut.

Vaginal Microbiome Transplants

Friday, 04 October 2019 by

Vaginal-Microbiome-TransplantsInspired by the success of Faecal microbiota transplantation (#FMT), two teams of scientists have been researching #vaginal #microbiome #transplantation. The belief is that by transplanting a whole microbial colony, rather than just one species (as happens with a #probiotic approach), we can help the beneficial microbes effectively gain control over the #pathogens. With faecal transplants becoming one of the most successful first-line treatments for Clostridium difficile and other gut infections, the hope is that vaginal microbiome transplants can offer the same hope for those with vaginal infections.

Antibiotics-Increasing-the-risk-of-Rheumatoid-Arthritis#Rheumatoid #arthritis is a long-term autoimmune condition that causes pain, swelling and stiffness in the #joints. A combination of genetic and environmental factors are suspected to be the cause for rheumatoid arthritis (#RA) including hormonal changes, exposure to dust and other allergens as well as some bacterial and viral infections. A team of researchers from Keele University, Haywood Academic Rheumatology Centre and Quadram Institute Bioscience have been studying the link between taking #antibiotics and going on to develop RA.

Antibiotic Harm to Children

Friday, 23 August 2019 by

Antibiotics-causing-more-harm-than-goodResearchers from Oxford, Cardiff and Southampton Universities have been studying the dangers of overprescribing #antibiotics for common #respiratory tract illnesses in children, concluding that children given two or more courses in a year are 30% more likely to have further doses fail. The research was published by the British Journal of General Practice and analysed patient records of more than 250,000 preschool children.

Organic Apples and the Gut-Microbiome

Wednesday, 21 August 2019 by

Organic-Apples-and-the-Gut-MicrobiomeFrontiers of Microbiology have published a new study examining the differences in bacterial composition and microbial diversity of organically grown versus conventionally grown apples. The #gut #microbiome plays a vital role in helping control digestion as well as aiding the immune system. An imbalance of healthy and unhealthy microbes in the intestines may contribute to high blood sugar, high cholesterol, weight gain and other disorders. This study focuses on the #plant-gut microbiome axis and the importance of #raw eaten plants as a source for microbes.

mBio150pxwide-11Now there will be those tempted to see this as a pitch for drinking more red wine….but let’s try and keep this in perspective, you see a this research looked at a compound found in red wine, resveratrol.  It found that it reduces the risk of heart disease by changing the gut microbiome, according to a new study by researchers from China. The study is published in mBio, an open-access journal published by the American Society for Microbiology.[1]

The authors are recorded as stating:

“Our results offer new insights into the mechanisms responsible for resveratrol’s anti-atherosclerosis effects and indicate that gut microbiota may become an interesting target for pharmacological or dietary interventions to decrease the risk of developing cardiovascular diseases,”

cover_natureA paper in Nature back in 2014 noted that artificial non-caloric sweeteners (NAS) when consumed by mice had a detrimental effect of their metabolic health and microbiota, and the authors suggested that this connection may be an indication of risk in humans who consume these additives. The study used three artificial sweeteners: saccharin, sucralose (which is Splenda®), and aspartame.

homecoverWhat? This is the act of applying vaginal bacteria to new-borns, not delivered vaginally to ensure exposure to the mother’s microbiome. Whilst at present, we don’t yet know whether the many conditions associated with C-section—including reported higher rates of allergies, asthma, atopic dermatitis, and even an association with autism diagnosis—are due to lack of exposure to the maternal vaginal microbiome to which, until recently, every surviving mammal had been exposed at birth.[1] Numerous people are considering this to be a prudent approach, as declining diversity of bacterial cohabitants are linked to increased problems with immune regulation and subsequent development of illness.

08A review article in Gastroenterologica e Dietologica explores the evidence for the use of LGG as a therapeutic probiotic.[1] Probiotics are becoming increasingly important in basic and clinical research, but they are also a subject of considerable economic interest due to their expanding popularity. They are live micro-organisms which, when administered in adequate amounts, confer a health benefit to the host.

From this very well-known definition, it is clear that, unlike drugs, probiotics might be useful in healthy subjects to reduce the risk of developing certain diseases or to optimise some physiological functions. They also may offer some advantages in already ill persons in relieving symptoms and signs, e.g. people with acute diarrhoea.

indexA fascinating open paper was published in microbiome in 2013, and its suggested conclusions are now more prescient than ever, as the relationship between genotype, phenotype, and metabolic repertoire in the microbiome is understood to be non-linear.[1] The requirement for a certain functional diversity to ensure a well-functioning cooperative intestinal microbiota is crucial to break down various complex dietary compounds and divide metabolic tasks among different community members.
