In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.

Celiac.com 05/09/2005 – To determine the effect a long-term gluten-free diet has on intestinal permeability in those with celiac disease, Canadian researchers divided celiac disease patients into three groups based on the length of time on a gluten-free diet: Group A less than 1 month; Group B, 1 month-1 year; Group C more than 1 year. Groups B and C were tested three times over the course of 12 weeks for lactulose/mannitol intestinal permeability, endomysial antibody, and 3-day food record. These results were compared to that of Group A and control subjects. The researchers found that intestinal permeability was elevated in those newly diagnosed with celiac disease and in those who were on a gluten-free diet for less than one year. They also found that it increased in those on a gluten-free diet for more than one year in those whose diets were contaminated with gluten. The researchers conclude that intestinal permeability normalizes in most people with celiac disease on a gluten-free diet, and gluten ingestion as determined by a 3 day food record correlates with intestinal permeability measurements. Further studies need to be done on the role of intestinal permeability testing in the follow-up care of those with celiac disease.
