Nanoparticles Change Intestinal Absorption of Nutrients

Nanoparticles Change Intestinal Absorption of Nutrients

Wikimedia commons /Public Domain Humans consume 100 trillion nanoparticles a day, according to the press release for a new study on nanoparticle influence on nutrient absorption . As the uses for nanotechnology become more widespread, from sunscreens to socks , we are just starting to learn about the possible effects these miniscule under-regulated particles may have on our health. A new study shines light on perhaps the scariest news yet: nanoparticles can change the rate at which nutrients are absorbed. If nutrient absorption is affected, it means that toxin absorption could also be affected. In even more disturbing findings, the study shows that nanoparticles caused "remodelling of the intestinal villi" -- changes in the intestinal linings which are critical for passing nutrients from ingested foods through to the bloodstream. Nanoparticles as Popeye's Kryptonite Althou...
