Gut Health Insights

How machine learning is applied to gut microbiome and VOC data, the accuracy figures actually reported in the literature, and the three documented reasons those figures often fail external validation

The chemistry of stool gas analysis: how the fecal volatilome forms, how GC-MS and electronic noses compare, and what the reported sensitivity and specificity figures actually are

Gut microbiome research breakthroughs with the studies and numbers attached: the gut-brain axis, immunotherapy response, fiber trials in type 2 diabetes, and the limits of probiotics

The Bristol Stool Scale measures consistency, not biochemistry. What its validation studies actually show, and how VOC analysis fills the gap in digestive health assessment

Where gut microbiome research stands now: multi-omics, precision nutrition, VOC analysis and machine learning, with the study sizes, effect sizes and external-validation failures behind each claim
