@Twelthlady -- Seriously, Lay's Potato Chips (Fritos, Plain Chips for sure) are gluten free in the US. We eat them when traveling. We have never been glutened by Lay's. Just read the label. I can not vouch for all the varieties because I have to watch for garlic and onion). Hubby eats regular Doritos too. Just read the label.
I know chips are not healthy, but in a pinch, we can stop at a mini-mart and grab them, eat them while campingor eatat a party. We buy the little bags when we are with extended family. No chance of cross contamination. When the bagsare first opened, we take them. The all bets are off after the bag is opened. My nieces and nephews....you have to worry about more than gluten! 
When you are first starting out, it is hard to digest anything, really. You have lots of damaged areas in your small intestine. That's why we recommend avoid junk processed foods for a while.
