Gluten-free eating is medically necessary for people with celiac disease and helpful for some with other conditions. The idea that a gluten-free diet is healthier for everyone is not supported by evidence. For people without these conditions, avoiding gluten can reduce whole grains and fiber, and gluten-free processed foods are often higher in sugar and fat.
The claim
Gluten-free products are marketed as healthier, and many people adopt the diet without a diagnosis.
What the evidence shows
- Heart health. A 2017 study in the BMJ of more than 100,000 US health professionals found that low gluten intake was not associated with lower heart disease risk and might reduce whole-grain intake.
- Weight loss. Weight changes on the diet usually reflect eating fewer processed foods, not removing gluten.
- Diagnosis first. Doctors advise testing for celiac disease before going gluten-free, because removing gluten can make testing unreliable.
