The Full Answer
There is a dangerous internet myth that sourdough bread is safe for people with celiac disease. This is FALSE. Traditional sourdough is made from wheat flour.
The fermentation process of the sourdough starter does break down some of the gluten proteins, making it easier to digest for people with mild non-celiac gluten sensitivity. However, testing shows that traditional sourdough still contains thousands of parts per million (ppm) of gluten, far above the FDA's safe limit of 20 ppm.
If you have celiac disease, eating regular sourdough will damage your intestines. You can, however, find specialized Gluten-Free Sourdough made from brown rice or sorghum starters, like those from Bread SRSLY or Schär.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Parts Per Million (ppm)
- Parts per million (ppm) is a unit of measurement used to quantify gluten concentration. Labeling laws in the US and Europe permit a maximum threshold of 20 ppm, while Australia requires no detectable gluten (0 ppm).
