It has been stated by a new study that dangerous chemicals inside some foods is being released by wrapping used to line popcorn and other junk food.

In the blood of those who ingest foods wrapped in these papers, University of Toronto scientists have discovered chemical contamination.

From chemicals used in the manufacture of certain products, such as non-stick pans, clothing and food packaging, Perfluorinated carboxylic acids or PFCAs are the breakdown products.

Scientists are being worried for years by these PFCAs that have been discovered in humans.

The consumption of polyfluoroalkyl phosphate esters or PAPs seems the major source of human PFCA exposure as these are the chemicals found in junk food papers.

Scott Mabury, the lead researcher and a professor in the Department of Chemistry at the University of Toronto said, "Those chemicals called PAPs move into food, make it into humans upon ingestion and metabolically are transformed into the PFCAs."

In an attempt to keep water and fat inside the food, these packages are lined with this chemical.

Mabury said that it can not be figured out how dangerous these chemicals are to humans and they are definitely dangerous.
