For the 3 million people in America (myself included) with celiac disease — an autoimmune disorder triggered by the ingestion of gluten — culinary life is a series of intricate leaps, accommodations and back-steps.

Two researchers have dubbed this phenomenon scarcity, and they say it touches on many aspects of our lives.
