Researchers warn nanoparticles in food, vitamins could harm human health

Science Codex, Feb. 16, 2012

Billions of engineered nanoparticles in foods and pharmaceuticals are ingested by humans daily, and new Cornell research warns they may be more harmful to health than previously thought.

A research collaboration led by Michael Shuler, a professor of Chemical Engineering and chair of Biomedical Engineering at Cornell University, studied how large doses of polystyrene nanoparticles – a common, FDA-approved substance found in substances ranging from food additives to vitamins – affected how well chickens absorbed iron, an essential nutrient, into their cells.

The results were reported online Feb. 12 in the journal Nature Nanotechnology.

  1. Vitamin D is an exiting vitamin that has received renewed interest in the research community. Its mechanism of action is being unraveled and it has been shown to have effects not only on calcium absorption but also wider effects on the body including prevention of cancer. In the last decade the sun safe message has been getting through to people, but as a side effect of this Vitamin D deficiency has now become more common.
