At the Dose the FDA Calls Safe, Two Sweeteners Reshaped the Guts of Mouse Grandpups That Only Drank Water
Chilean researchers fed mice sucralose and stevia at the doses the FDA calls safe. The metabolic marks showed up in grandpups that only drank water.
Nutrition & FoodYour Gut Bacteria Decide Whether Sorbitol Is Harmless or a Liver Problem
Sorbitol was sold for decades as the inert, guilt-free sugar swap. In zebrafish stripped of their gut bacteria, WashU researchers watched the intestine's own sorbitol reach the liver and feed the same fructose-metabolism pathway that packs on liver fat.
Metabolic & WeightYour Gut Remembers the Benzo You Quit Three Years Ago
Screen 2,509 people's guts against their prescription records and the fingerprint lingers: benzodiazepines, antidepressants and acid-reducers stay linked to a shifted microbiome years after the last pill, some rivaling antibiotics.
Autoimmune & InflammationHow Fiber Teaches a Self-Erasing Gut Wall to Remember for Two Weeks
Butyrate, the compound gut bacteria make from fiber, reprogrammed the intestinal lining of mice to keep raising IL-10 and blunting colitis for 2 weeks after the last dose, and the imprint held even in mice with no gut bacteria at all.
Nutrition & FoodCut the Fiber and Your Gut Bacteria Start Eating Your Own Gut Lining
Princeton isotope tracing found that when fiber runs short, gut bacteria strip protein off the mucus wall and churn out the same toxins that pile up in failing kidneys. Feed them whole plants and the chemistry flips.
Metabolic & WeightA Gut Microbe Was Feeding Ammonia to Sick Livers. A Michigan Peptide Cut Off the Supply in Monkeys.
The compound reversed severe fatty liver in monkeys by starving one ammonia-making gut bacterium. It also comes from a company its lead inventor founded, and no human has taken it for this.
Metabolic & WeightSleep apnea's heart damage may run through the gut, not the airway
Researchers at UCSD report that knocking out a single bile-acid receptor abolishes the arterial plaque sleep-apnea conditions would otherwise drive in mice. The mechanism fits the CPAP era's underwhelming trial record better than the airway story ever did.
