Gluten-Free is not just for Coeliacs.
This recently published study is a meaningful because it is high quality evidence that being gluten-free has significant long-term health benefit for people other than those diagnosed with coeliac disease. The findings provide evidence supporting a genuine biological relationship between gluten exposure and chronic immune dysregulation.
One of the greatest challenges in nutrition research is delineating from experiential evidence and quantifiable measurable evidence. Often people say, "I feel better when I don't eat gluten." While others say they notice no difference at all, and yet may be living with symptoms that don't appear to be connected to what they are eating.
This study is of particular good quality evidence in how GF diets impact immune behaviour. The researchers used a sophisticated technique called Mendelian randomization, analysing genetic data, and pulled a very large sample size of 500,000 individuals. This type of study design is the highest quality method available for investigating causal relationships in nutrition research. It minimises many factors that can bias previous conventional studies.
In this study, the researchers discuss mostly rheumatoid arthritis (RA). However they also discuss evidence that gluten avoidance reduces signifincantly influences specific immune cell populations involved in overall immune regulation. They state further research is needed to look at other specific chronic immune diseases. These findings, however, strengthen the growing body of evidence linking gluten exposure with damaged immune function.
Gluten exposure has a significant influence on the behaviour of the immune system. For people living with autoimmune disease and chronic immune activation conditions, a gluten-free diet is an important component of treatment management to reduce chronic immune activation and improving long-term health outcomes.
Studies like this one continue to move the conversation beyond opinion and personal experience to stronger scientific evidence that nutrition can play a meaningful role in regulating immune health.
