Just thought I'd pass this along, in case anyone's interested. There is a place here in Toronto that does food sensivity testing (as well as lots of other stuff - environmental and chemical sensitivities, nutritional deficiencies, etc.). For the food test, they can check your body's response to about 250 different foods. Then they give you a print-out of all the foods, ranked from most to least sensitive for you. I had this done about 6 or 7 years ago, and found it quite accurate (there were things I already knew I couldn't tolerate and those one's all showed up in the "severe" section). It's a quick, easy, and painless test. If you're interested in learning more, here's the website for the place I went: www.redpaw.net. I'm sure there are many places that do the same thing, but this is the only one I know of.
