Sourdough bread may be a better choice for people with diabetes than conventional bread because it often has a lower glycemic index and can lead to a more gradual rise in blood sugar.
Sourdough bread is often considered a potentially better option for people with diabetes than conventional bread because its fermentation process can result in a lower glycemic index (GI). The organic acids produced during fermentation may slow starch digestion and gastric emptying, which can lead to a more gradual rise in blood sugar and insulin levels after eating. However, it is not a low-GI food in all cases, and its impact can vary based on ingredients, such as the use of whole wheat flour. Experts emphasize that it should be consumed as part of a balanced diet, ideally paired with protein and healthy fats to further stabilize blood sugar, and portion sizes should still be monitored.
Answer details
Lower Glycemic Impact
The fermentation process in sourdough bread can lower its glycemic index compared to many commercial breads, potentially causing smaller spikes in blood glucose and insulin after meals.
Mechanisms of Action
Organic acids produced during fermentation may slow down starch digestion and gastric emptying, contributing to more stable blood sugar levels.
Dietary Strategies
Choosing whole-grain sourdough and pairing it with protein or healthy fats, such as avocado or hummus, can further help manage blood sugar responses.
Moderation and Balance
Sourdough is not a cure-all and should be consumed in moderation as part of an overall healthy, balanced diet tailored to individual needs.

Frontiers | Effects of sourdough and yeast fermented breads consumption on glycaemia in healthy populations: a systematic review
Bread is a vital source of energy and is widely consumed in human diets. As a carbohydrate-rich food, it is often considered to impair glycaemic homeostasis; however, clinical and molecular evidence suggest that its effects may vary depending on the characteristics of bread consumed. In particular, sourdough-fermented bread has been proposed to exert potentially beneficial effects on glycaemia via shifts in metabolites in the food matrix, as well

Utility of Flash Glucose Monitoring to Determine Glucose Variation Induced by Different Doughs in Persons with Type 2 Diabetes
Abstract: (1) Background: It has been previously shown that sourdough bread, compared to commercial yeast bread, elicits a lower postprandial glycemic and insulinemic response in patients with impaired glucose tolerance (IGT). Aims: Our aim was to evaluate the following aspects in persons with type 2 diabetes (T2DM): (1) glucose variations induced by three different doughs: X = bread prepared with functional alkaline biocrystal water, Y = sourdou

Exploring the Nutritional Impact of Sourdough Fermentation: Its Mechanisms and Functional Potential
Abstract: Sourdough fermentation is one of the oldest traditional methods in food technology and occurs as a result of fermentation of flour prepared from grains. The nutritional role of sourdough is related to the final composition of fermented foods prepared through sourdough fermentation, and recently, sourdough has become an important application to improve nutrition characteristics of bread. Thanks to lactic acid bacteria (LAB) presented in

Sourdough starter culture and breadmaking process impact wholemeal bread characteristics associated with starch digestibility
pH of 5.6 was found in the short-fermented bread loaves prepared with sourdough (Table 3). This may result from the buffering capacity of wholemeal flour and highlights that the acid production rate of the microbial consortium added primarily directed the acidification level of long-fermented wholemeal bread types. In contrast, the short- and long-fermented yeast-leavened bread loaves were not acidified (pH of 6.0 ± 0.1 and 6.2 ± 0.1, respectivel
