Least Processed Breads
Each product is ranked by its own Processing Score, lowest first. To keep the list from being one company's catalog, it shows at most two products from any one brand.
Bread by the Numbers
We scored every bread product in our database: 9,053 items across 931 brands. In our analysis, about 86% land in the Highly or Ultra-Processed tiers.
What should you look for on the label?
- Real bread needs only flour, water, salt, and yeast. Reject any loaf with 10+ ingredients
- Watch for DATEM, azodicarbonamide, and calcium propionate. All three signal industrial production
- "Whole wheat" does not mean less processed. Check the full ingredient list
- Look for "slow fermented" or "sourdough" which indicate traditional methods

How are products scored?
Every product is evaluated using two independent scores. The Processing Score (lower is better) measures the degree of industrial processing based on ingredient analysis, including the presence of artificial additives, preservatives, and highly modified ingredients. The Nutrition Score (higher is better) rates overall nutritional quality, rewarding protein and fiber while penalizing excess sodium, added sugars, and saturated fat.
Products are assigned to one of four processing levels: Minimal (score ≤ 2.5), Processed (2.6 to 5.0), Highly Processed (5.1 to 8.0), and Ultra-Processed (above 8.0). Each product in the ranking is placed by its own Processing Score, not by its brand. Based on our analysis of 445K+ curated products from the USDA FoodData Central database.

Frequently Asked Questions
What makes bread ultra-processed?
Industrial bread adds dough conditioners (DATEM, SSL), preservatives (calcium propionate), and sweeteners (HFCS) to speed production and extend shelf life. These additives can turn a 4-ingredient food into one with 20+ components.
Is sourdough bread less processed?
Yes. Traditional sourdough uses natural fermentation with only flour, water, salt, and starter culture, so it scores near the bottom of our scale. However, some commercial "sourdough" adds the same industrial additives as regular bread.
What is the best whole wheat bread?
The best whole wheat bread lists whole wheat flour as the first ingredient with minimal additives. In our analysis, the top-scoring whole wheat brands use 5-7 ingredients total. Avoid "wheat bread" that lists enriched flour first, as this is refined white flour despite the brown color.
What kinds of bread are least processed?
Among the many kinds of bread available, sourdough, traditional rye, and simple whole grain bread consistently score lowest. Sprouted grain breads (like Ezekiel) also score well. Brioche, sweet rolls, and flavored sandwich breads tend to score highest due to added sugars and industrial additives.
Which breads have the fewest ingredients?
The breads ranked here have the lowest processing scores in our analysis, each scored on its own ingredient list. Short lists built on flour, water, salt, and yeast score lowest.
