I personally try to avoid canned drinks and foods to avoid metal poisoning. I typically buy two liter sodas in plastic bottles and avoid softer plastics. Styrofoam cups and other styrofoam food containers are awful. If you get hot food in a styrofoam go box, the box is often visibly marked by contact with hot food and you can smell it and taste it.

It's also potentially a reason to switch to an electric vehicle -- to avoid exposure to gas fumes while refueling your vehicle. (Or you can be "an extremist nutter" like me and give up your car entirely.)
