Read that the wrappers from fast food contain chemicals that are bad for you and i ate food that was sticking to the wrapper today is it gonna do anything to me?

No. There are unwanted chemicals in the air and water we consume. While I would not recommend purposely exposing yourself to more chemicals, this one episode will not affect your health. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
