More than just saturated fat may be in your Big Mac: would you believe these are some of the same chemicals found in food packaging, floorings, window blinds, and soaps?

In a recent federal nutrition study that centered on the effects of fast food, those who reported eating fast food within a 24-hour period were found to have higher levels of certain industrial chemicals in their bodies. This study is the first to examine how fast food can expose consumers to harmful chemicals, not just fat and calories.

These chemicals, called phthalates, are used to make plastic and rubber more durable and flexible over an extended period of time and can be found in dust particles, plastic containers, and even the tubes used to pump milk into its packaging. Because of this, the chemicals can be diffused into food, which then leads to the direct exposure of the additives into the body.

Despite this shocking data, the public continues to choose chemical-filled Whoppers over its health.

McDonalds opened 1,600 new restaurants in 2014. And just as discouraging as true, one out of every four Americans eats fast food every day.
