Artificial Sweeteners and Gut Bacteria: The Human Trials
The sweetener-microbiome claim began with seven people and a lot of mice. Ten human studies later, the picture is smaller, slower and more person-specific than the headlines suggest.

Gut Circadian Rhythm: Why Bloating Persists When You Eat Clean
The gut runs on its own circadian clock. Late or irregular meals disturb enzyme timing and overnight motility, which can produce bloating that diet changes alone do not fix.
Gut Bacteria and Mood: Probiotic Trials and the SMILES Diet Study
Probiotic trials show small effects on mood scores, and the SMILES trial found a diet change beat social support for depression remission. A sober read of the gut-brain axis and mood.
Leaky Gut Foods: 4 That Support the Barrier and 3 That Damage It
Intestinal permeability is measurable, and diet moves it. Fermented foods, resistant starch, polyphenols and glutamine support the gut barrier; emulsifiers and alcohol weaken it.
Gut Bacteria and Fiber: Closing the Fiber Gap with Real Food
The average American eats six times less fiber than our ancestors did. The downstream effects go far beyond digestion.
Gut Microbiome and the Brain: A Fiber and Fermented-Food Plan
Gut bacteria signal to the brain through the vagus nerve, immune messengers and metabolites. What disrupts them, and a six-week fiber and fermented-food plan grounded in human trials.
Gut Health Guide: Microbiome, Probiotics and the Gut-Brain Axis
Evidence-based breakdown of the gut microbiome, leaky gut, probiotics, prebiotics, fermented foods, and practical protocols to optimize digestive and whole-body health.
Urolithin A: Mitophagy, Muscle Trials and Who Can Make It
Gut bacteria convert ellagitannins from pomegranate and berries into urolithin A, but not everyone carries the right strains. Randomized trials report modest muscle-endurance gains; what supplements can and can't add.
Probiotics and Gut Health: Strain-Specific Evidence vs Marketing
Probiotics are a multi-billion-dollar category with mixed evidence. Where they help (IBS symptoms, antibiotic-associated diarrhea), where they don't, and why strain matters more than CFU count.
