“Participants underwent intensive metabolic testing and provided blood and stool samples so the researchers could analyze insulin resistance, beta cell function, blood lipids, proteins, and gut microbes.”

“Authors of a new report detail the functional relationship between detrimental gut microbes and hippocampal memory in rats exposed to excess sugar during adolescence. Germ-free mice, which are born and raised in a sterile environment, demonstrate impaired brain development compared to mice with a normal gut microbiota.”

“Drinking kefir, a probiotic dairy beverage, improves memory. The community of microbes that comprise the gut microbiota act a bit like a sensory organ in the body, communicating information about the outside world to the brain and forming a gut-brain axis.”

“A recent editorial reports that many dietary supplements may be contaminated with heavy metals or microbes or may contain synthetic drugs or ingredients not listed on their labeling.”

“Gut microbes metabolize food, supplements, and medications and produce compounds such as short-chain fatty acids and bile acids, which are absorbed into the bloodstream and facilitate communication between the microbiota and host.”

“Cereal grains contain a mixture of insoluble fibers that bulk stool, viscous fibers that slow digestion, and fermentable fibers that feed the gut microbiota. Gut microbes break down cereal fiber, releasing micronutrients trapped in the fiber matrix and producing beneficial metabolic byproducts, such as short-chain fatty acids.”

“Choline is an important component of cellular membranes, a precursor for the production of neurotransmitters, and is incorporated into bile acids needed for the digestion of fats; however, some gut microbes convert choline into trimethylamine (TMA), which is absorbed by the intestine and converted to trimethylamine N-oxide (TMAO) in the liver.”

“Preclinical studies indicate that repeated weight cycling shifts gut microbes to a configuration with an altered ability to metabolize flavonoids — compounds that usually help promote the burning of excess energy by adipose tissue.”

“Instead, resistant starch undergoes microbial fermentation in the colon, providing nutrients for the microbes, and producing butyrate, a short-chain fatty acid that supports the health of colonocytes – the cells that line the colon and rectum (the end portion of the colon).”

“The review also highlights a "gut–bone connection": changes in gut microbes caused by microplastics may disrupt bone marrow stem cells by altering key growth signals that help regulate bone formation.”
