Damn, I hope not, but you could be right. Did you ever read Upton Sinclair's The Jungle? When it comes to processed meats, you very well may sleep better, not knowing, especially with some of the compounds fillers and flavor enhancers in many fast foods now days. Don't make a regular diet of fast food ground processed meat or fish sandwiches. You are running the original multi-fuel engine. You can literally live on damn near anything (trust me. I have had survival training) in the short run, but simply have to not let some things become your daily diet.
