What Do a McRib Sandwich and a Yoga Mat Have in Common?

The Answer Is Disturbing

Last week, McDonald's fans were upset to learn that the fast food giant had pushed back the date for its yearly limited-run release of the McRib sandwich until December.

But thanks to a Time magazine report (pointed out by AZFamily.com) about a certain ingredient in the sandwich, McRib fans might find themselves more than willing to hold off on the barbecue-y, rib-shaped treat.

Time.com reports that a McRib sammy contains 70 ingredients and among them are azodicarbonamide, ammonium sulfate and polysorbate 80.

Yeah, we don't know what that stuff is either, but Time put it into terms we certainly can understand: azodicarbonamide is a "flour-bleaching agent that is most commonly used in the manufacture of foamed plastics like in gym mats and the soles of shoes," and it's also found in the bun of the McRib sandwich.

To reiterate, the bun that houses the McRib patty is partially made of the same chemical that's used to make the yoga mat you lay your buns on to try to work off the calories you ingested while eating, yes, a McRib sandwich.

Uh … the circle of life?

Time's Healthland blog goes on to report that azodicarbonamide is banned in Europe and Australia as a food additive, but, as it appears in the McRib, it's in "small enough quantities to be innocuous."

As long as you don't think about the fact that you're eating a yoga mat and BBQ pork sandwich, that is.
