Your next question, as someone looking to go without gluten, is: How do I avoid falling prey to this ubiquitous hazard?
1. Food label 411. First and foremost, you have to start reading food labels. Anything emblazoned with the words "gluten-free" is your friend ("wheat-free" is not the same thing). We are fortunate to live in an era where ingredient lists are almost always available: Get used to recognizing common villainous names (dextrin, malt flavoring or extract, wheat starch, etc.). The Gluten Free Diet by Shelley Case is a great resource when it comes to learning your labels.
2. Call for Help. When in doubt, contacting companies directly on their 1-800 numbers is a good way to discover all the contents of a food item, while also drawing the companies' attention to the prevalence of gluten intolerance.
3. Make friends! It's also a great idea to join a celiac support group in your area, since word-of-mouth is an incredibly efficient and reliable way to get your gluten-free life on track. The Internet is also rife with educational websites to teach you how to live healthily and happily without gluten.
The moral of the gluten-free story is that, for once, there is no gain in pain. So put your upset stomach days behind you and embrace the adventure!
