A qiuck jump over to the US Census population clock tells me that our current population is 301,349,664. That means 99.3 percent of the US population suffer from celiac disease, "but most don't even know it." Actually, another quick jump, this time to the story, shows that only three million Americans are esimated to have celiac. Our silent epidemic isn't one of celiac; it's one of bad reading comprehension.
