Stop making light of the gluten-free diet. Are there people out there following a gluten-free diet for its perceived health benefits? Absolutely. Is it tempting to make fun of cultural fads? Certainly. Would we make fun of people with diabetes for needing to monitor their diets and use insulin? No. People with celiac disease don't have a choice.
Thankfully I'm lucky enough to have incredibly supportive family and friends. My network not only loves me, but they get me! They understand my nervousness and concerns about food that I don't prepare myself and they understand when I won't eat something and why. They take the time to learn and educate themselves, and for that I am eternally grateful.
