Titanium dioxide nanoparticles can exacerbate colitis

.
Prof. Gerhard Rogler

Titanium dioxide, one of the most-produced nanoparticles worldwide, is being used increasingly in foodstuffs. When intestinal cells absorb titanium dioxide particles, this leads to increased inflammation and damage to the intestinal mucosa in mice with colitis. Researchers at the University of Zurich recommend that patients with colitis should avoid food containing titanium dioxide particles.
