Darn, taking all dairy out is bit hard. I actually find that harder than taking out grains. But on the bright side, at least you got to keep eggs. @sift666 and I have both had to take out eggs as well for periods of time.

When you've trialled a few more foods and hopefully found a few more you can have, you might think about trying ghee. Sometimes (but not always) people who can't even have butter are ok on ghee which is pure fat, with no milk solids left. Start with just the tiniest bit and build up if no reaction.

I'd be inclined to wait two days between foods. I've known some people who haven't reacted for 48 hours, and then it gets very confusing to know what did what.

You grouped canola with tomato and a bunch of other nightshades. It's not a nightshade, is it?
