London - Eating lots of gluten in pregnancy doubles the risk of having a child with Type 1 diabetes, research suggests.
A study of 63 500 women found that the more gluten they ate during pregnancy, the higher the chance that their child would develop the condition by the age of 16.
The researchers, from Denmark, Iceland and the US, stressed that they had not proved the link and that more studies were needed before women should alter their diets.
But if confirmed, it would radically change the way medics think about Type 1 diabetes.
The autoimmune disease results in the body being unable produce its own insulin, stopping proper regulation of blood sugar.
