Registered dietitian Leyla Muedin discusses a Frontiers in Microbiology paper suggesting certain probiotics may help sequester heavy metals. The study, sponsored by the Italian company Probiotical and conducted with University of Ghent and University of Piedmont Orientale, researchers used in vitro testing and the SHIME gut simulator to assess Lactiplantibacillus plantarum, Lactobacillus crispatus, and Lactobacillus acidophilus against cadmium, lead, chromium, and mercury. L. plantarum and L. crispatus reduced metal bioavailability primarily in the simulated colonic phase, while L. acidophilus showed minimal detoxification; mercury was least reduced (~10%). An ex vivo mouse-intestine system found probiotic pre-incubation of metals preserved epithelial integrity...

Sleep, Glymphatic Detox, and the Hidden Heart Risks of Sleep Apnea: Nutritionist Leyla Muedin explains how sleep supports brain “housekeeping” via the glymphatic system, a glial-lymphatic waste-clearance network most active during sleep that moves cerebrospinal fluid through brain spaces to remove metabolites and toxic proteins such as amyloid beta, with sleep deprivation linked to amyloid accumulation. She notes other clearance pathways, including meningeal lymphatic vessels, whose impaired function is associated with neurodegenerative disease and brain injury. Reviews of human studies suggest sleep influences glymphatic outcomes, though results are inconsistent and methods vary. She emphasizes that poor sleep is associated with...
