New stool test identifies sensitivity to food emulsifiers

A new stool test can identify sensitivity to food emulsifiers like carboxymethylcellulose (CMC), which are linked to inflammatory bowel disease (IBD). This test offers insights into dietary adjustments for those affected. Researchers found that CMC alters gut bacteria in some individuals. They developed a model to predict sensitivity and confirmed that only mice with sensitive microbiota developed severe colitis after consuming CMC. The study identified a specific microbial signature in stool samples that predicts reactions to emulsifiers. This could lead to personalized dietary recommendations, especially for patients with chronic IBD. A new study will further investigate sensitivity to food additives.
