A new study in the journal of Exposure Science and Environmental Epidemiology tested fast food to see if it contained potentially harmful chemicals (phthalates and their replacement plasticizers). The chemicals migrate from packaging in to the food, and are linked to a long list of health problems including fertility issues, metabolic disruption, and (for kids) learning attention and behavioral problems.
The tested samples of hamburgers, fries, chicken nuggets, chicken burritos and cheese pizza were polluted with 10 of those chemicals. Meats such as chicken burritos and cheeseburgers were the most contaminated. Cheese pizza had the lowest levels of all chemicals that were investigated.
Ditch the fast foods pronto and limit the foods you buy that are packaged in plastic.
