# Sourdough Bread: A Deep Dive

## Summary

Sourdough bread is a fermented bread made with a 'sourdough starter'—a natural culture of wild yeast and lactic acid bacteria. This traditional method of leavening gives it a distinct tangy flavor and unique texture.

## Benefits

The fermentation process can improve digestibility and nutrient absorption, particularly for minerals like iron and zinc. May have a lower glycemic index than conventionally leavened bread, helping to stabilize blood sugar. Contains probiotics that support gut health. Generally made with minimal ingredients, often just flour, water, and salt.
