I bake sourdough because it’s delicious. But many people discover its tangy flavor because they have problems digesting other breads. Studies have found that sourdough—particularly homemade, long-ferment sourdough—is not only easier to digest but may have bonus health benefits. It makes sense if you think about it: You feed your sourdough starter flour. It eats it, turning it into more wild yeast and healthy bacteria. When you use it to make a bread, the longer the dough sits, the more it predigests the flour for you. As it does this, the sourdough bacteria release micronutrients, neutralize phytic acid, and stabilize blood sugar levels. And this all makes the bread twice as tasty.
The upshot is that if you have a gluten sensitivity but have not been diagnosed with full-blown celiac disease, you may be able to eat homemade sourdough breads. I’m not a doctor or nutritionist, so you should discuss this with yours, but there’s disagreement on whether gluten-free products, particularly commercially processed ones, are better than their homemade, wheat-based counterparts if you don’t have immune reactions to gluten.
