Researchers at Frontiers in Pediatrics tracked 81 children and teenagers (average age 15) with celiac disease across three periods: before the pandemic, during lockdowns, and after restrictions lifted. The key finding was striking: only about half the children had truly stuck to their gluten-free diets before COVID-19, but during lockdowns, this jumped to over 80%—and the improvement remained steady even after restrictions ended.
Celiac disease requires complete avoidance of gluten, a protein found in wheat, barley, and rye. Many children find this difficult, especially when eating outside the home.
Home cooking was the game-changer
When families stayed home and couldn't eat at restaurants, they gained much greater control over meals. Parents could read every label carefully, prepare food from scratch, and avoid the hidden gluten that often sneaks into restaurant dishes. This simple shift—from eating out to cooking at home—appears to have made the biggest difference in whether children could stick to their diet.
The study also found that dietary adherence was linked to family support and socioeconomic factors. This means managing celiac disease isn't something you handle alone; family involvement, education, and your financial situation all play real roles.
Cost and availability remain barriers for Singapore families
Nearly 9 out of 10 families reported struggling to find gluten-free products, with high costs and limited variety in shops as the main obstacles. This is particularly relevant in Singapore, where specialty gluten-free options remain expensive and not always readily stocked. Importantly, the study found that dietary adherence improved without needing expensive specialist products—simple, whole foods prepared at home work just as well.
One reassuring finding: children's physical growth measurements stayed stable throughout all three periods, suggesting that the compliance gains translated into real health benefits without causing new concerns.
Steps to support your child's gluten-free diet
- Prioritise home-cooked meals: increase the proportion of dinners you prepare at home, even if you can't manage every single meal. Simple batch-cooking on weekends gives you control over hidden gluten.
- Focus on whole foods rather than expensive specialist products: plain rice, vegetables, meat, and fruit are naturally gluten-free and more affordable than branded alternatives.
- Connect with other families managing celiac disease: community support groups and your child's doctor can point you toward affordable options and practical strategies.
