During the pandemic, my brother-in-law gifted me some of his sourdough starter (thank you Dustin!) and I managed to keep it alive and well for several months. My husband and I created some delicious sourdough concoctions. I noticed the sourdough bread I was eating didn’t seem to have as much of an impact as typical bread on my blood sugar. This led me to do some more research on the topic of sourdough bread and diabetes.
Sourdough bread isn’t your average supermarket white bread. It’s made through a long fermentation process using yeast and bacteria, which gives it that delicious tangy flavor. Lately, there has been a lot of buzz that this fermentation process might actually make it less impactful on blood sugar levels compared to other breads. Could this really be true? Is sourdough bread good for diabetes?
Let’s dig into what the research tells us!

What Makes Sourdough Bread Different?
So, what makes sourdough so different than other breads? It all comes down to the fermentation process. Unlike regular bread that relies on commercial yeast for a quick rise, sourdough uses a “starter” which is a live culture of wild yeast and bacteria. This starter is what gives sourdough its tangy flavor.
The magic happens as the starter ferments the dough. Lactic acid bacteria breaks down the starches and sugars in the flour. This process produces lactic acid, which not only contributes to the flavor but also has impacts the bread’s nutritional profile.
Sourdough and Blood Sugar
While research is ongoing, studies have shown that sourdough bread can have a noticeably milder impact on blood sugar levels compared to other breads. This is reflected in its lower glycemic index (GI). This means it causes a slower and gentler rise in blood sugar levels because the lactic acid bacteria may help to reduce the availability of carbohydrates for digestion, leading to a more gradual release of glucose into the bloodstream.
Some research indicates that sourdough fermentation could even improve insulin sensitivity. This means your body can use insulin more effectively to regulate blood sugar.
Keep in mind everyone responds differently to various foods and portion size still matters! Even with sourdough, it’s crucial to be mindful of how much you’re consuming and to monitor your blood sugar levels to see how your body reacts.
Of course, more research is needed to fully understand the impact of sourdough on diabetes, but the initial findings are promising!
Other Nutritional Perks of Sourdough
Beyond blood sugar benefits, sourdough brings other nutritional perks to the table. The fermentation process increases the bioavailability of certain minerals, making it easier for your body to absorb them. Sourdough is a good source of potassium and magnesium, both essential for heart health and blood sugar regulation.
Sourdough may act as a prebiotic, providing food for the beneficial bacteria in your gut. A healthy gut microbiome is linked to improved metabolic health and better blood sugar control.
The breakdown of gluten during fermentation can even make sourdough easier to digest, especially for those with mild sensitivities. It’s not completely gluten-free, so it’s not suitable for celiac disease, but it might be gentler on your system than other wheat-based breads.
Is Sourdough Bread Low Carb?
Sourdough bread is not technically considered low-carb. The fermentation process does slightly reduce the carbohydrates compared to conventional bread, as the starter consumes some of the sugars. However, it still contains a significant amount of carbohydrates. A typical slice of sourdough bread has around the same carb count as other breads, falling between 15-20 grams.
Does Sourdough Have Gluten?
Sourdough breads can be made from any type of flour, but the most common is wheat flour, which does contain gluten. As a result, sourdough bread made from wheat flour is not suitable for people with celiac disease or a gluten intolerance.
Gluten-free sourdough bread is available at some stores and can also be made at home with alternative flour such as tapioca flour, coconut flour, or almond flour.
Tips for Choosing and Enjoying Sourdough
Ready to give sourdough a try? When shopping for sourdough, read labels carefully and choose varieties made with whole grains for added fiber and nutrients. Look for breads with a short ingredient list and try to avoid those with added sugars or preservatives if possible.
Sourdough is incredibly versatile. Enjoy it as the base for avocado toast for breakfast, use it to make hearty sandwiches, or pair it with soups and salads.
Feeling adventurous? Try making your own sourdough bread! Once you get the hang of it, it really is a fun and simple process and the smell of fresh-baked sourdough bread is unbeatable. There are plenty of online resources and communities to guide you through your sourdough baking journey. There are even kits available to purchase that have everything you need!
Conclusion
So, is sourdough bread good for diabetes? While there may not be anything magical about it, sourdough bread does offer some promising potential benefits. From its lower glycemic index and improved insulin sensitivity to its gut-friendly prebiotics and enhanced nutrient absorption, sourdough seems to have some benefits that other breads lack.
But remember, moderation and mindful consumption are still crucial. Always pay attention to portion sizes and monitor your blood sugar levels to see how your body responds. If you don’t enjoy sourdough bread, don’t worry. There are plenty of other high-fiber, diabetes-friendly bread options that you can choose from instead.
The good news is that managing diabetes doesn’t have to mean deprivation! With smart choices and a few tricks up your sleeve, you can enjoy delicious foods like sourdough bread while keeping your blood sugar happy.
