Gluten-Free Diet
A medically necessary pattern for celiac disease—not a default wellness upgrade.
What Is It?
A gluten-free diet removes wheat, barley, rye, and ingredients made from them. It is the essential treatment for celiac disease and may also be prescribed for other diagnosed gluten-related disorders.
How It Works
Naturally gluten-free foods form the base, while labels, preparation surfaces, and cross-contact require close attention. People who suspect celiac disease should be tested before removing gluten because starting the diet can make diagnostic results less reliable.

EVIDENCE What the research says
For celiac disease, lifelong gluten avoidance is established treatment. For the general population, going gluten-free has not been shown to be inherently healthier or a reliable weight-loss strategy, and an unplanned version may be low in fiber, iron, and calcium.
