What else might this be true of, though? Could this just as easily be true of, say, sugar consumption or meat consumption?

Probably most things. Processed foods, various forms of radiation etc. American Experience had a pretty cool show last season (S32E2)on Dr. Harvey Wiley, an american chemist that could largely be considered the father of the FDA. The amount of stuff put in food is pretty crazy.

The reality is the body is pretty resilient though. Its pretty amazing the amount of abuse it can withstand and still keep on ticking.
