A few weeks ago, on a trip to British Columbia, I ate in a local restaurant. When eating out, I always try to order something simple, without a gravy or sauce, since these sauces are bound to contain MSG. So I ordered a plain crab cake with rice and vegetables—no sauce, no mayo. Boy, did that crab cake taste good! About midnight I knew why. I woke up with a dry mouth, a terrible thirst and a headache. The next day I felt sore all over, like I’d been in a fight. My hands felt like they had arthritis.
