For whatever it's worth... Lundberg's rice chips contain corn as the second ingredient on the list. (I figured this out only *after* feeding them to my corn-sensitive kid. Oops.)
Also, I'm pretty sure that I've read that Terra Chips contain traces of wheat, at least in some varieties, though right now when I did a web search the only place I found that mentioned was in somebody's blog (namely here:
http://glutenfreegirl.blogspot.com/2...de-potato.html -- in the fourth paragraph it says, "Terra Chips, the gourmet chips with exotic vegetables, should be gluten-free. But some of the varieties are not. I learned that the hard way....").
Sorry to be the ingredient grinch. :-(
