Damn, that rules out like...so much stuff. No soy sauce, no miso, no edamame which are all things I swore by on my sick diet to restore electrolytes after my water binges(damn, having the runs from those types of illnesses had me chugging water like fratboys do beer.)

I guess you can use sea salt for a soy sauce substitute. I know it's blasphemy but hey, when you're sick, you're sick.

Hope you find out what the hell is going on...
