Trader Joe's Sprouted Wheat Sourdough Bread "Made with a traditional fermentation process, sourdough offers notable gut-health benefits. This process breaks down gluten and phytic acid, while also adding beneficial bacteria, making sourdough easier to digest and promoting better gut health.

As a result, the Trader Joe's item attracts fans from across the internet. Its charm is in its subtlety. Unlike some highly fermented options, this grocery store version is mild in flavor and enjoyably wheaty. And, because sourdough is made via fermentation, it might be easier to digest (per Medical News Today).

Sourdough bread's fiber, potassium, phosphorus, and sodium content all support a heart-healthy diet. The soluble fiber found in sourdough bread binds to dietary cholesterol in the small intestine, helping pass this fat through the system instead of absorbing it.

All types of sourdough are relatively healthy, says Largeman-Roth, but the healthiest type of bread — sourdough or otherwise — is whole wheat or whole grain. Whole-grain bread is made with flour containing the entire wheat kernel.
