About National Celiac Disease Awareness Day
History & origins
September 13 is designated in U.S. awareness calendars as National Celiac Disease Awareness Day (the date is associated with Dr. Samuel Gee, who described the diet-disease link). It is an education date, not a festival.
Why it matters
The day exists because undiagnosed celiac disease still harms people, and because ‘gluten-free’ marketing is not the same as medical need.
How to celebrate
Learn what celiac disease actually is, do not ‘test’ people with gluten, and cook a truly gluten-free meal if you are hosting someone who needs it.
