A new study finds that those fiber bowls used in places like Chipotle contain non-biodegradable chemicals linked to kidney and testicular cancers.

And it's not just Chipotle that uses these cardboard-type bowls that have become all the rage because they are supposedly compostable.

The study has found that these bowls have "forever chemicals" that pose serious health conditions.

The new investigation of the beige bowls by New Food Economy included extensive testing on the molded fiber from which these bowls are made.

Research found that these bowls tested positive for high levels of fluorine, indicating they were treated with per-and poly-fluoroalkyl (PFAS) compounds.

According to the EPA, these man-made chemicals are very persistent and don't break down in the human body, which means they can accumulate over time. That's why these bowls can withstand hot, wet, and greasy foods that would normally destroy a paper plate or bowl.

This means that they are, in fact, NOT environmentally conscious.

Chipotle issued the following statement:

“We are committed to using safe and sustainable food packaging and only partner with suppliers who make fluorochemical sciences and food safety a top priority. These suppliers operate under strict guidelines set forth by the FDA, and have all provided chipotle with certification that all raw material and finished pulp products fully meet regulatory requirements.”
