Celiac.com 01/16/2018 - More and more, people are adopting a gluten-free diet due to perceived health and weight-loss benefits.
The research team included Loren G. Rabinowitz, Haley M. Zylberberg, Alan Levinovitz, Melissa S. Stockwell, Peter H. R. Green, and Benjamin Lebwohl. They are variously affiliated with the Department of Medicine, Celiac Disease Center, Columbia University College of Physicians and Surgeons New York USA; the Department of Philosophy and Religion James Madison University Harrisonburg USA, the Department of Pediatrics Columbia University College of Physicians and Surgeons New York USA, the Department of Population and Family Health, Mailman School of Public Health, Columbia University New York USA, the Department of Epidemiology, Mailman School of Public Health, Columbia University New York USA, and the Celiac Disease Center at Columbia University New York USA.
Their team conducted an online survey of celiac and non-celiac gluten sensitivity patients from a celiac disease center e-mail list. They used univariate and multivariate analysis to compare responses from the two groups. The overall response rate was 27%, with 217 non-celiac gluten sensitivity responses, and 1,291 celiac disease responses.
Subjects with non-celiac gluten sensitivity were more likely than those with celiac disease to disagree with the statement that "vaccines are safe for people with celiac disease." In all, 41.3% of respondents with non-celiac gluten sensitivity said vaccines are safe for celiacs, while just 26.4% of celiac patients said so. Celiac patients were slightly more likely to decline vaccination when offered, at about 31%, compared with just over 24% of gluten-sensitive respondents.
After adjusting for age and gender, non-celiac gluten sensitivity subjects were more likely than celiac disease subjects to avoid genetically modified (GMO) foods, eat only organic products, believe that the FDA is not a reliable source of information, and believe a gluten-free diet will improve energy and concentration.
People with non-celiac gluten sensitivity were more likely than those with celiac disease to have doubts about vaccine safety and to believe in the value of non-GMO and organic foods.
The team's findings suggest that there might not be enough easily accessible information on gluten and its inclusion in food and drugs, and that may reinforce incorrect beliefs that are contrary to good public health.
