Is Sourdough Bread Good for Diabetics?
Whether sourdough bread is “good” for diabetics depends on several factors, but it can be included in a diabetes-friendly eating plan. Sourdough bread can offer some advantages compared to other types of bread due to its unique fermentation process. This process may lead to a lower glycemic index (GI), meaning it might cause a slower rise in blood sugar levels after eating. However, individual responses vary. Portion size, overall meal composition, and the specific ingredients in the bread all play a role. It is important to monitor your blood sugar levels after eating sourdough bread to understand how your body reacts.
Key takeaways
- Sourdough bread may have a lower glycemic index (GI) than some other breads.

Why this happens
The key to sourdough’s potential benefits lies in its fermentation process. During fermentation, the naturally occurring bacteria (lactobacilli) in the sourdough starter break down some of the carbohydrates in the flour. This process can result in a lower GI. The GI measures how quickly a food raises blood sugar levels. Foods with a lower GI are generally considered better choices for people with diabetes because they cause a slower, more gradual rise in blood sugar. This is similar to how a well-maintained garden irrigation system prevents small leaks from becoming major problems. A slow, steady release of water (glucose) is preferable to a sudden flood.
However, the GI of sourdough bread can vary. It depends on the type of flour used (whole wheat vs. white), the length of fermentation, and the presence of other ingredients like added sugars. Whole-grain sourdough bread often has a lower GI than sourdough made with refined white flour. The longer the fermentation process, the more the carbohydrates are broken down, potentially leading to a lower GI. The addition of ingredients like honey or molasses will increase the GI.
The impact of sourdough on blood sugar also depends on the individual. Factors such as insulin sensitivity, overall health, and the presence of other medical conditions can influence how the body responds to carbohydrates. For example, someone with well-controlled diabetes and a healthy lifestyle might tolerate sourdough bread better than someone with poorly controlled diabetes and other health issues. It is important to remember that everyone reacts differently to food. What works well for one person may not work as well for another.
Real-world scenarios
Best-case scenario: A person with well-controlled type 2 diabetes eats a slice of whole-wheat sourdough bread with avocado and a poached egg for breakfast. They monitor their blood sugar two hours later and see a moderate, expected rise, well within their target range. They feel satisfied and energized throughout the morning. This person is also physically active and follows a balanced diet.
Typical scenario: A person with type 1 diabetes eats a sandwich made with sourdough bread for lunch. They carefully calculate the carbohydrate content of the bread and adjust their insulin dosage accordingly. They monitor their blood sugar levels before and after the meal and make minor adjustments to their insulin as needed. They are aware of the impact of different types of bread on their blood sugar and make informed choices. They also consider the other ingredients in the sandwich, such as the protein and vegetables, when planning their meal.
Higher-risk scenario: A person with newly diagnosed, uncontrolled type 2 diabetes eats a large portion of white sourdough bread with jam for breakfast. They do not monitor their blood sugar levels and experience a significant spike in blood sugar, followed by a crash. They feel tired and sluggish throughout the morning. This person might also be less physically active and have a diet high in processed foods and added sugars. They may need to consult with their healthcare provider to adjust their treatment plan.
Risk factors and what may help
| Risk factor | Why it matters | Who is most affected | What may help |
|---|---|---|---|
| Type of flour | White flour has a higher GI than whole-grain flour. | People who eat sourdough made with white flour. | Choose sourdough made with whole-wheat or whole-grain flour. |
| Portion size | Larger portions of bread lead to a greater carbohydrate intake, which can raise blood sugar levels. | People who eat large servings of sourdough. | Control portion sizes; measure bread servings. |
| Added ingredients | Ingredients like honey or molasses increase the sugar content and GI. | People who eat sourdough with added sugars. | Read food labels carefully; choose sourdough without added sugars. |
| Meal composition | Eating bread alone can cause a faster blood sugar rise. | People who eat bread without protein, healthy fats, or fiber. | Pair sourdough with protein, healthy fats, and fiber-rich foods. |
| Overall health | Poorly controlled diabetes and other health conditions can affect blood sugar control. | People with uncontrolled diabetes or other health issues. | Work with a healthcare provider to manage overall health. |
| Physical activity | Lack of physical activity can worsen insulin resistance. | People who are not physically active. | Engage in regular physical activity. |
| Medications | Certain medications can affect blood sugar levels. | People taking medications that affect blood sugar. | Discuss medications with a healthcare provider. |
| Individual insulin sensitivity | How the body responds to insulin varies. | Everyone. | Monitor blood sugar levels and work with a healthcare provider. |
Symptoms and early signs
People with diabetes can experience various symptoms related to blood sugar fluctuations. These symptoms can vary from person to person. Early signs of high blood sugar (hyperglycemia) might include increased thirst, frequent urination, blurred vision, fatigue, and slow-healing sores. Early signs of low blood sugar (hypoglycemia) might include shakiness, sweating, dizziness, confusion, and hunger. It is important to recognize these signs and take appropriate action. For example, if you are experiencing symptoms of low blood sugar, you may need to consume a fast-acting carbohydrate, such as glucose tablets or juice, to raise your blood sugar levels. If you are experiencing symptoms of high blood sugar, you may need to adjust your diet or medication, but always consult with your healthcare provider first.
How it’s checked
Blood sugar levels are typically checked using a blood glucose meter (glucometer). This involves pricking a finger to obtain a small blood sample, which is then placed on a test strip inserted into the meter. The meter provides a reading of the blood sugar level. Continuous glucose monitors (CGMs) are also available. These devices continuously track blood sugar levels throughout the day and provide real-time readings. Regular A1C tests are also used to measure average blood sugar levels over the past two to three months. These tests provide a broader picture of blood sugar control. Blood sugar levels should be checked at various times, such as before meals, after meals, and before bed, as recommended by a healthcare provider. The frequency of testing depends on the individual’s treatment plan and overall health.
