Do nano-sized particles in food additives cross into the bloodstream?
Unknown risk. Nanoparticles in food packaging and additives are under-studied. Avoid when alternatives exist.
What's actually in it
Engineered nanoparticles are particles smaller than 100 nanometers intentionally added to products for specific properties: antimicrobial silver nanoparticles in packaging, titanium dioxide nanoparticles in sunscreen, zinc oxide nanoparticles in sunscreen.
The concern is that nano-sized particles behave differently than their bulk counterparts. They can cross biological barriers that larger particles can't.
