Thanks for the post, but I'm curious about something - salt is not supposed to dehydrate; it's supposed to help a person stay hydrated. Pro golfers and some extreme runners take salt pills to help their bodies hold onto water while competing.
My doc gave me a short list - obvious stimulants, such as tobacco, caffeine, etc. Alcohol is a biggie - it is a mental depressant but a heart stimulant. Anything that dehydrates is going to aggrivate them too - super salty stuff. I notice if I go out for sushi (soy sauce!) I will get PVCs if I don't make sure to drink tons of water. Cold medicines, he said, I should also avoid, and chocolate, because it has caffeine in it.
Personally, and I don't know if it's just me or what, but artificial sweeteners and lots of preservatives (msg) don't seem to sit well with me either.
