Much like this infographic breaking down single food items (an egg, a banana) into a list of their chemical components, it makes an important point about the food we eat and chemicals: Simply calling a food item a "chemical" — while it may certainly alarm some people — doesn't really share any information. The vitamins we eat are chemicals. The medicines we take are chemicals, too. And, as this chart notes, some of them are very, very good for us.
