Yes! Sourdough is most definitely better for your gut! Sourdough is low GI which means it will keep you feeling fuller longer. It's also less likely to spike your blood sugar like regular bread. It's much easier to digest (and better for your gut) because it has lower phytate levels thanks to the lactobacillus and wild yeast. Sourdough has more nutrients than regular bread, despite being made from just flour, water and salt.
