How many people are on a gluten free diet?

Hey, so I just want to know basically how many people are on a gluten free diet, who do not have celiac disease? I can''t find it on the internet, but if you did, I''d love to know because I need an actual concrete fact for my essay on gluten-free people :) Thanks so much! :D

Recommended Answer:
Unfortunately, no one actually knows. Estimates are that around 3 1/2 million people have celiac disease, based on randomized studies of thousands of people and what the percentage of THAT population tests positive for the disease.

However, comparing that to actual diagnosed Celiacs, you find that 3% of that number have been diagnosed. so if the estimate is accurate, then around 3 MILLION celiacs are undiagnosed. How many of these are eating gluten free could skew the statistic, obviously. :-/

Although this might have some information that could be of use:
