Despite all the precautions I take when eating out by choosing restaurants who pride themselves in using local, organic, sustainable ingredients and offer gluten-free options, I recently suffered from gluten exposure. I got "glutened" through cross-contamination at one of my favorite restaurants. Aside from the immediate reaction (tongue swelling, bloating, cramping), I also endured various side effects (headache, acne, fatigue, insomnia, etc.) for many days afterwards, which lowered my immunity to the point of catching a nasty cold days later that I am still recovering from.
