A new report in the journal Nature Nanotechnology has found that ultra-fine grains, nanoparticles commonly used in our drugs and processed foods could change the surface structure of our intestinal lining.

Nanoparticles like titanium dioxide or aluminium silicate are increasingly used in pills or food, and consumed by their trillions each day by folks in the global North. Ultimately, these nanoparticles may be changing the way we digest food and absorb nutrients….and most likely for the worse.
