An observational study from Lund University, published in the American journal Gastroenterology, suggests that a fibre-rich diet up to the age of two may reduce the risk of developing coeliac disease in later life.
The study followed 6,500 children with a genetic risk for coeliac disease. Researchers discovered that children who consumed high-fibre diets before the age of one had a significantly reduced risk of developing coeliac disease by age 13. Increasing fibre intake by about three grams per day lowered the risk by almost 40 per cent.
The study highlights that the type of fibre—whether from fruits, vegetables, grains, or legumes—did not matter; rather, it was the overall proportion of fibre that influenced the risk. The researchers theorize that early fibre intake positively affects the gut microbiota, which supports a stronger immune system and gut barrier.
While these findings are promising, they are based on observational data, and further clinical trials are needed to confirm the connection. Nonetheless, this research underscores the potential benefits of fibre-rich diets in early childhood and could inform future dietary recommendations.
