<<Disclaimer: Verify this information before applying it to your situation.>> Thanks for 26 responses to the advice from a "top London Dietitian" that: no one should withhold gluten from the diet unless they have had the villi sample, which as you know is invasive and risky to say the least To cut out gluten in a child's diet could cause hypersensitivity risks if they accidentally ate it with possibly disastrous consequences. Several people advised less-invasive blood or saliva tests, before resorting to villi biopsies, but add that the risks associated with the biopsy are no greater than with any other procedure. To quote one person: The biopsy is not 'invasive and risky' - in fact, if your daughters want to watch one, contact FOX Network (USA)'s 'Popular Mechanics for Kids'. They televised one about a year ago. My (now) 8 year old celiac found it fascinating. Others argued that any risk should be balanced against the damage caused by gluten ingestion. Most of you disagreed with the notion that withholding gluten could cause sensitivity, on the contrary many of you have seen improvements to health and well-being since going gluten-free. Some respondents believe in testing for sensitivity before eliminating gluten from the diet others just do it! Most of you thought that the "top dietician" should stick to giving dietary advice, unless specially trained in the area of celiac disease, and gluten- intolerance. One person suggested I withhold my advice, to my daughters, and let them alone to raise there children in their own way. Quote: Having put up with an exceedingly controlling mother who thought nothing was ever done right concerning "her" grandchildren unless it was done the way she thought it should be, I'd strongly suggest that you not argue with your daughter as how her children should be treated even if you "think" their health will be endangered. Thanks everyone! I have forwarded all of the responses to my daughter, in the UK, and will leave it at that. Valerie, California
