Food choices with a gluten-free diet
The April Nutrition Society Paper of the Month is from Journal of Nutritional Science and is entitled “What happens to food choices when a gluten-free diet is required? A prospective longitudinal population-based study among Swedish adolescent with coeliac disease and their peers”.
The results of a serologic blood sample test can lead a study subject to change their diet. That was true for some of the 12-13 years old adolescents who participated in a large celiac screening study (‘Exploring The Iceberg of Celiacs in Sweden’ 2005-2006) and who were diagnosed with celiac disease (CD) during the study period.
We studied how a diagnosis of (CD) affected food intake by performing a food survey using a food frequency questionnaire (FFQ). Food intake was measured at baseline before the adolescents were diagnosed and in a follow-up study 12-18 months later, after diagnosis and prescription with a gluten-free diet. Given the importance of the adolescents getting older during the study, we were also interested in their food intake compared with the same aged adolescents with symptom detected CD in early age and non-celiac control groups.
The results showed that the screening detected adolescents reported a reduced intake of many flour-based foods such as pizza, fish fingers, and pastries. The results also indicated that the reported bread intake was lower in the screening diagnosed group, even before they received their diagnosis, as compared to the other study groups. Apart from the bread intake, the screening detected group reported at baseline, a very similar food intake to the non-celiac control group. At follow-up, the screening-detected group reported an intake much more similar to the symptom detected group than to the non-celiac control group. Specially manufactured Gluten Free (GF) products (e.g. pasta and bread) were frequently used in the screening detected CD group after changing to a GF-diet. The availability of manufactured GF-replacement products seemed to make it possible for adolescents to keep many of their old food habits when diagnosed with CD in Sweden.
