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.
