KD, it's just like any food preparation/preservation... Some foods are better dehydrated and others freeze dried. One day I hope to have a freeze dryer next to my dehydrators.
This looks like the model dehydrator that teila posted.

Nope no ill effects. I'm personally with KD on this one and feed left over chicken to the pigs and left over pork to the chickens but there's no nutritional issue in play with my choices. Pickles should be fine in moderation as you indicated salt is a concern.
I've got wheat bread rising so plan on making a couple of loaves for sandwich bread to take to work. Ron, I got a little brave and substituted about 25% of the wheat flour with bread flour to make it a bit lighter. Results were a little patchier than desired so kneaded in another table spoon or two of bread flour. Is this going to work? I'm getting braver.
