Summary
In this episode, Dr. David Jockers dives into the science of sourdough bread and its impact on blood sugar and digestion. Learn how the fermentation process reduces gluten, making it easier on your gut and improving overall health. Dr. Jockers also shares the benefits of postbiotics found in sourdough and their role in stabilizing blood sugar levels.
You’ll discover why sourdough bread has a lower glycemic impact compared to traditional bread, making it a better option for managing blood sugar. Dr. Jockers explains how this bread can help with digestion by stimulating stomach acid and bile, improving the absorption of nutrients.
While sourdough bread is not gluten-free, it offers a significant reduction in gluten content, making it a healthier alternative for many. For those with chronic inflammatory conditions or gluten sensitivities, Dr. Jockers advises moderation, but for the healthy individual, sourdough can be a delicious and beneficial addition to your diet.
