The Canadian Celiac Association Labelling Survey Reveals Significant Challenges For Individuals On A Gluten-Free Diet

Shelley M Case RD, Donald R Duerksen MD FRCPC, Melissa Secord CAE

Reading ingredient lists and labelling claims are essential to determine the safety of foods for individuals on a gluten-free diet (GFD). The complexities of food labelling, how manufacturers convey gluten contamination risk and what appears on product packages can be challenging for consumers to understand and make informed safe choices.

The Canadian Celiac Association (CCA) conducted an online labelling survey to gauge understanding about precautionary statements (PS) and other claims on labels for those with celiac disease (CD), not diagnosed with CD who follow a GFD, caregivers/parents and dietitians.

Introduction of Gluten-Free Oats in the Gluten-Free Diet of Children and Adults with Celiac Disease: An International Survey

Shelley M Case RD, Caleigh E McAulay, MSc Nutrition Science, Vanessa G Ramouche, Dominica A Gidrewicz, MD

Guidelines highlight that pure uncontaminated gluten-free oats (GFO) are considered safe as part of the strict gluten-free diet (GFD) to treat celiac disease (CD). Yet controversy amongst clinicians exists as to the timing of introducing GFO, in clinical remission versus newly diagnosed versus other. Members of the celiac community want to consume GFO as part of a healthy balanced GFD and want to understand when it is safe to do so.

This purpose of this survey was to evaluate current recommendations from around the world about the:

  • Timing of introducing GFO
  • Type of oats recommended
  • Follow-up approaches for children and adults after GFO introduction
  • The goal of further research is to create safe and effective recommendations for clinicians and reduce confusion in the CD community.

Assessment of Availability of Safe Gluten-Free Diet to Residents of Long-Term Care Facilities

Zaynab Al-Nuaimi, RD, Melissa Secord, CAE, Dr. Mohsin Rashid

Treatment of celiac disease is a strict, lifelong gluten-free diet (GF diet). Individuals with celiac disease in long-term care (LTC) facilities may be vulnerable to gluten cross-contamination as they might lack means of advocating for themselves.

The aim of the study was to identify gaps involved in provision of safe GF diet to residents in LTC facilities.

Access to gluten-free diet across Canadian Universities and Colleges

Students currently attending a Canadian University or College who may have been diagnosed with CD, non-celiac-gluten sensitivity (NCGS) or follow a gluten-free diet (GFD) for another reason are invited to participate.

As the number of individuals adhering to a gluten-free diet rises, there is a need to identify barriers that students adopting a GFD face on campus at Canadian universities to ease their access to viable gluten-free options. Our hope is that this survey will help us understand more about the challenges faced by students adopting a GFD in Canada, further contributing towards more education in the near future.

This survey will take approximately 3 minutes to complete.  This collaborative research study survey conducted by clinicians and researchers from McMaster University and the Canadian Celiac Association.

The risk of contracting COVID-19 is not increased in patients with celiac disease

This past spring CCA along with many patient organizations across the world participated in a study of patients with celiac disease (CeD) and their experience and knowledge of COVID-19.  Numerous studies suggest that celiac disease (CeD) is associated with an increased risk of respiratory infections. However, how it relates to the risk of COVID-19 is unknown. To address this gap, the investigators conducted a cross-sectional study to evaluate whether patients with self-reported CeD are at an increased risk of contracting COVID-19. Patients were asked to complete an online survey and a total of 18,000 individuals participated. The Canadian celiac community represented the vast majority of participants in the study and we thank them for their participation. The study concluded that patients with CeD have similar odds of contracting COVID-19 and may not need to take additional precautions to prevent exposure aside from the recommended to the general public. Longitudinal studies employing repeated measurements will contribute to a better understanding on whether the risk of contracting COVID-19 in CeD changes over time.

Association Between Inflammatory Bowel Diseases and Celiac Disease: A Systematic Review and Meta-Analysis

In a systematic review and meta-analysis, the study found an increased risk of IBD in patients with celiac disease and increased risk of celiac disease in patients with IBD, compared with other patient populations. High-quality prospective cohort studies are needed to assess the risk of celiac disease-specific and IBD-specific biomarkers in patients with IBD and celiac disease.
