Wheat gluten and immune cell response in people with type 1 diabetes
What it found
In people newly diagnosed with type 1 diabetes, immune cells reacted slightly more to wheat gluten than in people without diabetes.
Overall responses were low and uncommon.
What they found
Studies in people
Immune response at diagnosis
Seven out of 29 people newly diagnosed with type 1 diabetes (24.1%) showed a stronger immune cell reaction to wheat gluten. Only two out of 37 people without diabetes (5.4%) had this reaction.
Longer-term diabetes patients
Six out of 39 people who had lived with type 1 diabetes for a longer time (15.4%) reacted to wheat gluten. Their response did not differ from people without diabetes.
Overall response was low
The typical immune cell reaction to wheat gluten was small across all groups. The middle value was 2.0 for newly diagnosed patients and 1.5 for people without diabetes.
Genetic risk markers
The immune cell reaction to wheat gluten was not linked to specific genetic risk factors for type 1 diabetes in these patients.
What the authors conclude
- They found that while immune cell reactions to wheat gluten were slightly higher in newly diagnosed patients, such reactions were rare overall.
- The authors say their results do not support a major role for wheat gluten in causing type 1 diabetes in people.
How it was done
Animal models of human type 1 diabetes have linked dietary wheat gluten to diabetes risk. The authors wanted to see if wheat gluten acts as a trigger for immune cells in people with this condition.
They tested blood samples from 29 people newly diagnosed with type 1 diabetes, 39 who had the condition longer, and 37 people without diabetes. They measured how much the immune cells multiplied when exposed to wheat gluten.
What it can’t tell you
- We summarised it from the abstract only.
- This study looked at immune cells in blood samples, so it cannot show whether eating wheat gluten causes or worsens diabetes in daily life.
- It only measured one type of immune response at one point in time, so it cannot track what happens over months or years.
