Is Sourdough Bread really better for you than regular bread? Ask Martha Stewart.
Sourdough’s long fermentation boosts digestion and gut health by increasing probiotics, prebiotics, and reducing hard-to-digest carbs.
Its fermentation also reduces gluten and phytates, improving nutrient absorption—though it’s still not safe for people with celiac disease.
Compared with most breads, sourdough has a lower glycemic index and offers antioxidant benefits that support blood sugar control and reduce oxidative stress.
