Dietitian's Tips for Consuming Sourdough Bread

  • Metabolic Effect: It has a lower glycemic index compared to other breads, which helps to keep blood sugar levels more stable and helps you stay full longer. Thanks to the fiber it contains, it supports the digestive system.
  • Consumption Recommendation: Instead of consuming it alone, consuming it with healthy fats and proteins such as cheese, avocado or olive oil can balance blood sugar. It can be preferred for breakfast or lunch.
  • Things to Consider: One slice of sourdough bread may have the equivalent calories of approximately 2-3 slices of normal bread. It is important to pay attention to portion control, especially for those who want to control their weight.
  • Exercise Equivalent: To burn the calories (96 kcal) from one slice of sourdough bread, you need to walk for about 20-25 minutes. This time may vary depending on your daily activity level.
