Introducing Gluten to Infants: Current Guidelines
Updated September 2026
Parents and caregivers may wonder when gluten-containing foods should be introduced to their baby, particularly when celiac disease runs in the family.
Current evidence suggests that the timing of gluten introduction does not prevent celiac disease. Gluten-containing foods can be introduced as part of complementary feeding any time between four and 12 months of age.
Does the timing of gluten introduction affect the risk of celiac disease?
Research has investigated whether introducing gluten earlier or later in infancy could change a child’s risk of developing celiac disease.
Earlier studies produced conflicting findings. A 2020 analysis of the Enquiring About Tolerance (EAT) study found that children introduced to gluten beginning at four months of age had fewer diagnoses of celiac disease at age three than children in the standard introduction group. However, celiac disease was a secondary outcome of the study, there were very few cases of celiac disease, and longer-term evidence was needed before concluding that early gluten introduction could prevent celiac disease.
Since then, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has reviewed the available evidence. Its updated 2024 position paper concludes that introducing gluten at any time between four and 12 months of age does not appear to affect the overall risk of developing celiac disease during childhood.
Based on current evidence, there is no recommendation to introduce gluten earlier or later within this period specifically to prevent celiac disease.
How much gluten should be introduced?
There is currently not enough evidence to recommend a specific amount of gluten when gluten-containing foods are introduced.
Some observational research has found an association between higher gluten intake in early childhood and an increased risk of celiac disease or celiac disease autoimmunity, particularly among children with a genetic predisposition. However, the evidence is not sufficient to determine an optimal amount of gluten or to recommend limiting gluten as a strategy to prevent celiac disease.
Gluten-containing foods can be introduced as part of a varied diet when an infant is developmentally ready for complementary foods.
What about breastfeeding?
Breastfeeding has many recognized benefits and should be encouraged according to general infant-feeding recommendations.
However, current evidence does not show that breastfeeding reduces the risk of developing celiac disease. Introducing gluten while an infant is still breastfeeding has also not been shown to prevent celiac disease.
Decisions about breastfeeding should therefore be based on its established health and nutritional benefits rather than as a strategy to prevent celiac disease.
What if celiac disease runs in the family?
Children with a first-degree relative with celiac disease are at increased risk of developing the condition. However, current evidence does not support different recommendations for the timing of gluten introduction in children who are at increased genetic risk.
Gluten should not be avoided in an infant’s diet in an attempt to prevent celiac disease. Celiac disease testing also requires ongoing gluten consumption to provide accurate results.
Parents and caregivers with a family history of celiac disease can speak with their child’s healthcare provider about when screening for celiac disease may be appropriate.
Key takeaways
- Gluten-containing foods can be introduced as part of complementary feeding between four and 12 months of age.
- Introducing gluten earlier or later within this period has not been shown to prevent celiac disease.
- There is currently no specific amount of gluten that has been shown to prevent celiac disease.
- Breastfeeding has many health benefits but has not been shown to prevent celiac disease.
- Children with a first-degree relative with celiac disease are at increased risk and should speak with their healthcare provider about appropriate screening.
