Updated news on gluten sensitivity

In a recent study, a new type of gluten sensitivity was identified.  Researchers studied a very specific group of people:  they were family members of someone who had been diagnosed with Celiac Disease, they were all positive for one of the Celiac genes (DQ2) and they had all had been tested for CD by blood test and biopsy and found to be negative.  But many of them also had symptoms of CD.  They found that tTG antibodies are often present in the small intestine even though it does not show up on a blood test and the biopsy is normal.  Those people who had symptoms improved on the gluten free diet and the tTG deposits disappeared.  This study supports the idea that many relatives who have symptoms of CD may very well benefit from a gluten-free diet even though their tests are negative.  http://www.ncbi.nlm.nih.gov/pubmed/21471568
