The Claim

Food additives, including emulsifiers, sweeteners, colors, and microparticles/nanoparticles, affect gut health outcomes such as the gut microbiome, intestinal permeability, and intestinal inflammation, with evidence primarily derived from preclinical animal and in vitro studies.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

Some ingredients added to food, like thickeners, sweeteners, and tiny particles, might change how your gut works—like the bacteria living there, how leaky your gut is, or if it gets inflamed—based mostly on studies in lab animals or cells.
