Dietitian's Tips for Consuming Sourdough Starter

  • Metabolic Effect: Sourdough starter contains probiotic bacteria and supports the digestive system. It has a low glycemic index, which means blood sugar rises more steadily.
  • Consumption Recommendation: Sourdough breads are more filling than regular breads. It can be preferred for breakfast or lunch.
  • Things to Consider: It has a high fiber content, so it is recommended to consume it with plenty of water. Excessive consumption can cause gas and bloating.
  • Exercise Equivalent: To burn one slice of sourdough bread, you need to walk for about 20 minutes.
