As for Bars and stuff, go for ODWALLA BARS. Although one or two of the varieties do have nuts, the others don't say "may contain traces of nuts" on the label. I've called the company to make sure there's no cross contamination. I've been eating those bars in mass quantities for years and haven't had a problem -- taste pretty reasonable too. They have a few varieties which are without either nuts or chocolate -- cranberry is pretty good, and they have ok protein bars too.

I've had Odwalla bars too - they are pretty tasty and easy to find, even Safeway carries them
