Zurch, my wife thought she might have a gluten allergy, she was having symptoms of feeling bloated and having no energy if we ate sandwiches or pizza or pasta. I adjusted to her eating habits and she ended up losing a lot of weight, having more energy, and overall being a lot happier. If she accidentally eats something with wheat in it, she knows right away because her throat gets scratchy/itchy and she gets stomach aches pretty quickly. Some GF items can be expensive like bread, but over all those things are a lot easier and cheaper to find now than they were 5-7 years ago. Most places we go out to eat now offer GF options where for a few years we couldn't go out for pizza or burgers. If I wanted either I'd have to hold out when I'm out with buddies since she couldn't eat anything at most places. Cooking with rice or corn flour is an easy adjustment, and if she wants a beer she has a New Grist. At first making this work for her was difficult for both of us, but it was obviously better for her. Once we figured out where and what she could and couldn't eat without having to look at the ingredients, it's not even something we think about anymore. Aldi is a great place to grocery shop for GF things too. If she enjoys beer, there's a lot out there that qualify as GF, because they are made with rice and not wheat (bud light, corona, etc) but there is barley in there. I have some friends that say they can't eat wheat but can drink certain beers, though my wife won't risk it. Just try things out, but it's probably of your best interest to not mess with your wife's diet to prove a point.
