About Sourdough slice
Sourdough bread is a type of fermented bread made from a naturally occurring yeast and lactic acid bacteria starter, believed to have its origins in Ancient Egypt over 5,000 years ago. This bread has a chewy texture, tangy flavor, and is a staple in various cuisines worldwide, especially in Western countries where it is enjoyed in artisan bakeries. Sourdough typically contains fewer ingredients than commercial bread: flour, water, salt, and the sourdough starter. It is known for its long fermentation process, which enhances its digestibility by breaking down phytic acid, making minerals like magnesium and iron more bioavailable. On average, one slice of sourdough bread (about 60 grams) provides approximately 160 calories, 32 grams of carbohydrates, 6 grams of protein, and small amounts of B vitamins, iron, and selenium.
Health Benefits
- Improved digestion due to natural probiotics (lactic acid bacteria) aiding gut health.
- Increased mineral bioavailability, as the fermentation process reduces phytic acid, enhancing the absorption of magnesium and iron.
- Rich in selenium, contributing to antioxidant defense and supporting the immune system.
- Low glycemic index compared to regular bread, potentially helping with better blood sugar control.
- Provides B vitamins such as thiamin and niacin, essential for energy metabolism.
Dietary Considerations
Selection and Storage
Store sourdough bread at room temperature in a breathable bag for up to 3 days or freeze it for longer storage. Avoid refrigeration as it may dry out the bread.
Common Questions About Sourdough slice Nutrition
How many calories and nutrients are in a slice of sourdough bread?
A single slice of sourdough bread typically contains around 120-150 calories, 4 grams of protein, and 1 gram of fat. It provides small amounts of vitamins such as B vitamins and minerals like selenium and manganese, but it is not a significant source of fiber.
Is sourdough bread compatible with a keto or low-carb diet?
Sourdough bread is not typically compatible with a keto diet since it contains around 20 grams of carbohydrates per slice, which is too high for maintaining ketosis. It may work for a moderate low-carb diet if consumed sparingly.
What health benefits or concerns are associated with eating sourdough bread?
Sourdough bread is easier to digest due to its fermentation process, which breaks down gluten and phytic acid. The probiotic bacteria used in sourdough may support gut health. However, it is still a refined carbohydrate and can contribute to spikes in blood sugar if eaten in excess.
What is the recommended serving size for sourdough bread?
The recommended serving size is typically one slice of sourdough bread, which is about 50-60 grams. Pairing it with protein and healthy fats can balance its carbohydrate content and make it more filling.
How does sourdough bread compare to regular white bread?
Sourdough bread generally has a tangier flavor and a chewier texture compared to white bread. It is easier to digest due to natural fermentation and may have a lower glycemic index. White bread, however, tends to be softer but less nutritious overall.
