Knowing what to eat, and how to avoid cross-contamination or accidental exposure is very difficult. For a sufferer of Celiac Disease, exposure to gluten can tear up the esophagus and cause scarring, (eosinophilic esophagitis can be related) and it takes as much as a month to heal. Unsurprisingly, people with these conditions need to eat. There are also people who have real, legitimate allergies to wheat (not the gluten, but the wheat), as diagnosed by allergists with labwork.


This is somewhat controversial, but shouldn't be: There are a large number of people who suffer from Celiac Disease, which is the inability to process Gluten.
