“Two strategies – prebiotics and probiotics – merit attention, with varied scientific support. Prebiotics are dietary components (primarily indigestible fibers) that promote the growth and survival of beneficial microbes in the human gut.”

“Microbes in your gut may trigger your motivation to exercise, a new study in mice has found. Compounds produced by the microbes signal the release of dopamine – a neurotransmitter produced in the brain that promotes the "runner's high" and the desire to exercise.”

“Immune cells in the intestinal epithelium secrete immune factors into the mucus layer, allowing friendly bacteria to colonize space close to the barrier, crowding out unfamiliar microbes. When this complex filtering system weakens, microbial toxins in the bloodstream increase, a condition known as endotoxemia.”

“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.”

“A recent study found that mice without gut microbes, known as germ-free mice, had lower exercise capacity and used oxygen and glucose less efficiently during physical activity. Researchers compared germ-free mice to mice with normal gut bacteria.”

“A rodent study reconciled this anomaly by demonstrating that gut microbes convert berberine to dihydroberberine, a more absorbable form of the compound (fivefold greater). A study in humans indicated that berberine exhibited differential metabolism due to variations in gut microbial makeup related to dietary intake.”

“Microbes in the gut interact in complex ways with metabolism and produce beneficial metabolites that support human health. In other cases, the body, its microbes, and a food or environmental element may interact in a detrimental way.”

“In another study, depletion of beneficial microbes that strengthen the gut barrier, such as Akkermansia muciniphila, increases blood pressure and small vessel disease burden.”

“The exposome comprises tangible and intangible exposures, ranging from food, air, physical surroundings, microbes, and chemicals to psychological stressors, education level, and financial status, among others, and likely has diverse effects on human health.”

“The extent of these impairments correlated with the donors' cognitive abilities and the presence of inflammation-promoting microbes. They also noticed differences in microbial metabolites in the rats' guts, including taurine, an amino acid that supports hippocampal neurogenesis.”
