The almost constant dizzy spells I kept getting seem to have been the result of gluten. I've been mostly gluten-free for a few months now, but once in a while I'll eat a slice of toast or something, and the next day, I get a dizzy spell that lasts a day or two. So, I'm pretty sure there was a connection. I've never been official tested, because by the time I figured this out for myself, I was so fed up with doctors and health care insurance, that I want nothing to do with any of them.
I don't understand the fuss about finding special "gluten-free" food. You don't need to replace foods with special gluten free varieties of the same thing. Like on "Snow Cake", where all she has in the house are some nasty little gluten-free crackers. Why not have some tortilla chips (which, to me means a good brand, not something overprocessed like Doritos, which probably have some kind of gluten-containing seasonings.)
I eat rice and potatoes instead of pasta. I miss French bread and crackers, but that's not the end of the world. Instead of having a plate of cheese and crackers, I have cheese and apple slices. There are plenty of traditional diets throughout the world that don't involve any gluten. Well, certain candy bars do, like Twix.
I'll just fry up a bunch of vegetables in olive oil, with some chicken or something, and put that over rice. There's not gluten in any of that.
I don't eat ice-cream with chunks of cookie in it. I drink cider instead of beer. (That one is tough, because here in the US it's hard to find hard cider. A lot of people have never even heard of it. It's just a matter of time before the one grocery store I have access to decides to stop carrying it. ) And thank goodness chocolate doesn't have gluten.
In other words, a gluten-free diet isn't hard if you just keep it simple. Don't buy packaged foods with ingredients lists a mile long. Fruit, vegetables, meat, eggs, milk, non-gluten-containing grains....that's all you need. And some of that you don't even need.
I miss cold cereal, like Life, but you get over it. That stuff is too expensive anyway.
The hard part, for me, is that I have 3 other people in my family, 2 of whom will eat nothing but bread and chicken nuggets.
