Which group of people is most commonly affected by celiac disease?

Celiac disease is an autoimmune disorder that affects a significant portion of the population, approximately 1% of individuals in the U.S. This condition primarily impacts those who have a genetic predisposition to it and manifests upon the consumption of gluten, a protein found in wheat, barley, and rye. The correct answer underscores the statistical prevalence of the disease rather than the age or specific demographics.

While young children may present symptoms due to a previous exposure to gluten, celiac disease can develop at any age, which makes focusing solely on young children somewhat misleading. Additionally, it is important to note that although pregnant women can have unique nutritional concerns, they do not have a higher incidence of celiac disease compared to the general population. The reference to adults over 50 is also inaccurate, as celiac disease is not limited to that age group either. Thus, highlighting the 1% prevalence rate effectively encapsulates the widespread but often underdiagnosed nature of celiac disease across various demographics.
