Claussen pickles are the best

not sour or bitter like Vlassic or other cheap brands.
Never heard about pickles being bad...but then again, like the legendary Paraselcus* said:
"Moderation is the key." I'm sure if you ate enough of anything you could get sick from it, not just a tummy ache but other underlying things such as liver, kidney, bowel problems among other things.
Paraselcus is the 'father' of toxicology, where he explained that medicines in the recommended doses was best, but an overdose could lead to sickness or death.
Example: Take an aspirin for a headache. Take more than one at one time or more than four, six times a day [as the bottle says] could be dangerous.
THOUGH....I have heard if you eat mass quantities of foods over a long period of time that you could actually become the pigment of the foods you eat; pickles day and night for a long period of time, your skin tone turns a little green.
