Sourdough is one of the oldest breadmaking methods — flour, water, salt, and a wild yeast starter. Commercial white bread typically contains 15-20 ingredients including dough conditioners, preservatives, and added sugars. The processing gap between these two is among the largest in the bread aisle.
Bread & GrainsQuick Answer
True sourdough (Level 1-2, 4 ingredients) is dramatically less processed than commercial white bread (Level 3-4, 15-20 ingredients). If reducing processing is the goal, sourdough from a bakery with a short ingredient list is one of the best bread choices available.

Frequently Asked Questions
What makes sourdough less processed than white bread?
Sourdough relies on natural fermentation from wild yeast and lactobacilli cultures rather than commercial yeast and dough conditioners. A true sourdough needs only flour, water, salt, and starter. Commercial white bread adds DATEM, calcium sulfate, monoglycerides, and other industrial ingredients to speed production and extend shelf life.
Is all sourdough bread minimally processed?
No. Some commercial "sourdough" is regular bread with added vinegar or sourdough flavoring. Check the ingredient list — real sourdough should have 4-6 ingredients and list "sourdough culture" or "starter," not "sourdough flavor."
