Study participants who ate less gluten tended to eat less cereal fiber, a known protective factor for developing type 2 diabetes.
Eating more gluten may be associated with a lower risk of developing Type 2 diabetes, according to research presented at the American Heart Association’s Epidemiology and Prevention / Lifestyle and Cardiometabolic Health 2017 Scientific Sessions.
A small percentage of the population cannot tolerate gluten due to Celiac disease or gluten sensitivity, but gluten-free diets have become popular for people without these conditions, even though there is lack of evidence that reducing gluten consumption provides long-term health benefits.
“We wanted to determine if gluten consumption will affect health in people with no apparent medical reasons to avoid gluten,” said Geng Zong, Ph.D., a research fellow in the Department of Nutrition at Harvard University’s T.H. Chan School of Public Health in Boston, Massachusetts. “Gluten-free foods often have less dietary fiber and other micronutrients, making them less nutritious and they also tend to cost more. People without Celiac disease may reconsider limiting their gluten intake for chronic disease prevention, especially for diabetes.”
Micronutrients are dietary components such as vitamins and minerals.

- Gluten-Free Diet Linked to Increased Levels of Toxic Metals
- Twenty Percent of Children with Celiac Disease Do Not Heal on a Gluten-Free Diet

In this long-term observational study, researchers found that most participants had gluten intake below 12 grams/day, and within this range, those who ate the most gluten had lower Type 2 diabetes risk during thirty years of follow-up. Study participants who ate less gluten also tended to eat less cereal fiber, a known protective factor for Type 2 diabetes development.
After further accounting for the potential effect of cereal fiber, individuals in the highest 20 percent of gluten consumption had a 13 percent lower risk of developing Type 2 diabetes in comparison to those with the lowest daily gluten consumption (approximately fewer than 4 grams).
