Evidence of lactate producing gut bacteria as a key memory-boosting molecule

Said Janice Jansson, a microbial ecologist at Pacific Northwest National Laboratory, “our study shows that the microbiome might partner with genetics to affect memory.” Researchers discovered that the Lactobacillus and L. reuteri strains were linked to improved memory, as well as two additional strains of Lactobacilli. The team fed lactate (produced by Lactobacillus) to mice that had poor memory and noticed that their memory improved. Gamma-aminobutyric acid (GABA), a molecular messenger linked to memory formation in their brains. This is another step foreward and a factor in the gut-brain axis, though not yet complete, admits Jansson.

94% accurate detection of liver disease by gut bacteria
Jul
18
The New Atlas July 01 2020 reported that the Salk Institute and the University of California San Diego discovered that our gut bacteria can accurately detect liver disease by 90%. Examining the stool samples of 163 healthy and sick patients, these researchers discovered a signature based with 94% accuracy on the presence of 19 bacterial species that was indicative of liver disease, specifically non-fatty liver disease or NFLD. The research was led by Rohit Loomba, co-corresponding author and director of the NAFLD Research Center at the UC San Diego School of Medicine.

Common food additive harms our gut bacteria

The article acknowledges that the UMASS study of mice may or may not directly apply to humans. However, it suggests that the larger particles of titanium dioxide used as additives in food are safer. This is one of a number of studies that point toward this same result.

A "disease quadrangle"- gut microbiome link to COVID -19
Jul
10
One study in Cell says "microorganisms are increasingly recognized as ecosystem-relevant components because they affect the population dynamics of hosts," suggesting a four-tier influence or "disease quadrangle" by host, host microbiome, pathogen, and environment (1). This report recommends better understanding the role of microbiomes in disease dynamics. A Medical News Today article implies the traditional "disease triangle" may be obsolete. For example, in the case of malaria, a mosquito is less likely to become vulnerable to the malaria parasite if it has more bacteria belonging to the Enterobacteriaceae family in its gut (2). The Enterobacteriaceae species protects against malarial infection. Researchers have found that climate temperature has a strong effect on the growth of pathogens and gut bacteria, and therefore the spread of disease.
Which brings us to our current COVID-19 problem. It is already known that gastrointestinal symptoms are common among people testing positive for COVID-19. A stronger link still as reported by Medical News Today say research found the presence of SARS-CoV-2 in the stool of COVID-19 patients (3). Though more research is required to conclusively prove these links, there is strong evidence that these links affect the severity and risk level of patients.
One point that can't be denied is that a significant paradigm shift has arrived with the fourth factor in how we look at disease and disease prevention. Host microbiome, is a critical part of understanding how we treat and prevent diseases.

Health benefits of lavender oil

One popular lavender oil Silexan was found to contain 36.8% of linalool and 34.2% of linalyl acetate26, according to a December 2019 human clinical study reported in Nature Magazine (2). The Nature report points out that anxiety disorders in United States reaches as much as 28.8% of the mostly working population, compared to 14.5% in Europe, and 20% in Australia.
Lavender oil is so concentrated that you often need to combine it with a carrier oil (like coconut, jojoba and argan oil, to name a few) before applying directly to your skin. Most reputable producers will have already included the carrier oil, ready to use.

Connection found between gut microbiome and cholesterol levels
Jul

Scientists have known there to be a connection between cholesterol and the gut for centuries. The study was able to determine that the IsmA gene in gut microbiome of people they studied have 55 to 75 percent less cholesterol in their stool. “Those who have this enzyme activity basically have lower cholesterol,” said Dr. Balkus' co-senior author Ramnik Xavier, core member at the Broad Institute, co-director of the Center for Informatics and Therapeutics at MIT, and investigator at Massachusetts General Hospital.
Balskus and her associate Doug Kenny, a Ph.D. candidate in her department, sequenced the entire genome of the cholesterol-consuming hog bacterium, according to the Harvard Gazette in order to isolate the IsmA gene.

How gut microbiome interact with prescription drugs

The researchers identified 57 cases in which gut bacteria can alter existing oral medications, which can alter the medications to be less effective, not effective at all, or even toxic. Unfortunately, the Princeton study will require more detailed study of specific gut microbiome strains to isolate which bacteria are affecting the medications and how.
The SciTech Daily reported that "researchers found that some people’s microbiomes had little effect on a given drug, while other microbiomes had a significant effect," causing a wide variability between individuals tested. In addition, Princeton's Donia said it calls for studying of various drugs on the "entire intestinal microbial community.”

How does exercise affect your gut microbiome?

It is well known that the microbes living in our guts are altered through diet such as dietary fiber and dairy products, which support the growth of beneficial bacteria in our gut. But mounting evidence suggests that exercise can also modify the types of bacteria that reside within our gut.
Inverse reported one study found exercise promotes the growth of bacteria that produce a fatty acid, butyrate. Butyrate can promote repair of the gut lining and reduce inflammation, therefore potentially preventing diseases such as inflammatory bowel disease and diabetes.
Inverse found a study of mice that were given a high-fat diet – increased Firmicutes and Proteobacteria in their gut, which are linked to type two diabetes and obesity.

Recommended Salt intake positively influences gut microbiome

Short-chain fatty acids, or SCFAs, are known to play a key role in regulating your blood pressure. Dr. Zhu claims it is the first ever human study to look at how "decreasing salt intake in humans affects circulating short-chain fatty acids." However, Zhu found that the study's results were more conclusive for women than men. The article quotes Dr. Zhu saying, "We need to study it further. . . It may be that high-salt affects blood pressure through different pathways in males and females."
The study was reported by the American Association for the Advancement of Science, https://www.eurekalert.org/pub_releases/2020-06/mcog-hdi060920.php .
