Pickles are not a bad food. I love pickles and I watch my salt intake. I also retain water easily. I haven't found pickles to be detrimental. Just practice moderation (in other words don't eat the whole jar) and don't go drinking the juice. Lol.
I actually have to visit this particular deli whenever I visit my sister. They have the best pickles! I bought 5 lbs at Christmas time. And, Yes, I still have some left.
