Don't you have to get the right balance of sugars and salt? So not enough salt could cause a problem? Doesn't the brewer diet emphasise the need to get the right amount. I don't think it's a problem if you are eating lots of processed food, and by processed, I don't necessarily mean junk, regular bread and cereals have a fair amount in, but if you don't eat things like that and you aren't adding salt to food you could possibly not be getting enough.
When did you last have your blood pressure checked? Can you pop to a drugstore and check it yourself? Have you been noticing the increase in swelling gradually, or more suddenly?
