A new study revealed that gluten sensitivity is not related to gluten, but rather is part of the gut-brain interaction mechanism. These results are expected to set a new standard for defining, diagnosing, and treating gluten sensitivity, and avoiding unnecessary dietary restrictions.
The study was conducted by researchers from the Australian University of Melbourne, and its results were published in The Lancet on October 22, and the Eurick Alert website wrote about it.
Gluten protein is found naturally in some grains, including wheat and barley. People with non-celiac gluten sensitivity experience symptoms after eating gluten, but they do not suffer from celiac disease, an autoimmune disease caused by gluten. Common symptoms include bloating, intestinal pain, and fatigue.
Lead researcher, Associate Professor at the University of Melbourne, Jessica Pyzikerski, said these findings overturn long-held assumptions about gluten sensitivity.
“Contrary to popular belief, most people with non-celiac gluten sensitivity do not react to gluten,” Dr. Jessica said.
“Our results show that symptoms are often triggered by fermentable carbohydrates, other wheat components, or people’s expectations and previous experiences with the food,” she added.
The researchers reached these results by reviewing published research related to the condition, and the researchers found only a few experiments that revealed any real interaction with gluten.
Stay away from the mainstream narrative
Dr. Jessica added, “In recent studies, people with irritable bowel syndrome who believe they have a gluten sensitivity react similarly to gluten, wheat, and a placebo. This suggests that people’s expectations of their gut response can strongly influence their symptoms.”
“This redefines non-celiac gluten sensitivity as part of the spectrum of gut-brain interaction, closer to conditions like irritable bowel syndrome, rather than a distinct gluten-related disorder,” she continued.
The research team says the findings have major implications for people who self-treat their symptoms, for doctors who prescribe restrictive diets, and for policymakers who shape public health messages.
Dr. Jessica said, “Millions of people around the world avoid gluten because they believe that it harms their intestines, and this is often after the appearance of real symptoms ranging from mild discomfort to severe distress.”
Dr. Jessica added that effective care for people with non-celiac gluten sensitivity should combine dietary modifications and psychological support, while ensuring nutritional adequacy.
She would like to see public health messaging move away from the narrative that gluten is inherently harmful, as this research shows that is often not true.
