Bread is a staple food in many Asian and European countries. One variety that has recently gained popularity is sourdough, which is made through a natural fermentation process involving yeast and lactic acid bacteria from the flour. What makes sourdough bread stand out, and why is it often chosen as part of a healthy diet? Read on to find out.

What is Sourdough Bread?

Sourdough bread differs from regular white or sweet bread commonly available in stores. Most bread is made by adding instant yeast, but sourdough uses wild yeast as its fermentation agent, which is cultivated by mixing water and flour. This natural yeast produces lactic acid, giving sourdough its distinct sour flavor and helping to eliminate harmful bacteria.

The natural fermentation in sourdough bread enhances its health benefits and eliminates the need for additives like sugar. This makes sourdough easier to digest, more nutritious, and less likely to cause sharp blood sugar spikes.

Nutritional Content of Sourdough Bread

A 50-gram serving of sourdough bread typically contains:

• Calories: 185

• Protein: 2 grams

• Fat: 1 gram

• Carbohydrates: 36 grams

• Fiber: 1 gram

• Sugar: Less than 1 gram

The natural fermentation process also increases the levels of beneficial minerals in sourdough bread, such as calcium, sodium, magnesium, iron, and zinc. Additionally, it contains potassium, folate, and niacin.

Health Benefits of Sourdough Bread

Some key health benefits of sourdough include:

Easier to Digest

The fermentation process in sourdough bread reduces gluten content. Gluten, a protein found in grains like wheat and barley, can be difficult to digest. While gluten gives bread its chewy texture, sourdough made with reduced gluten tends to have a drier, less chewy texture, which may be easier on digestion.

Sourdough bread also has lower levels of other compounds, such as FODMAPs, phytates, and tannins, making it easier to digest compared to regular bread. This makes it a safer choice for those with gluten intolerance or digestive issues.

Contains Prebiotics and Probiotics

Research has shown that sourdough bread can act as a prebiotic, providing nourishment for beneficial gut bacteria. These microbes are essential for maintaining a healthy digestive system.

Helps Maintain Normal Blood Sugar Levels

Sourdough bread has a lower glycemic index and glycemic load compared to white bread or unfermented whole wheat bread. When made with whole wheat, sourdough has more fiber, which helps prevent spikes in blood sugar levels. As an alternative carbohydrate source, sourdough is a healthier choice, particularly for those following a diet or managing diabetes.

Prevents Premature Aging

Including whole grains and sourdough bread in your diet is a key aspect of the Mediterranean diet, which is recognized for promoting heart health and preventing premature aging. Studies suggest that fermented grain products like sourdough have antioxidant, antihypertensive, and antidiabetic effects.

Side Effects of Eating Sourdough Bread

While sourdough is generally healthier, it can have some digestive side effects. It's important to note that sourdough is not completely gluten-free, making it unsuitable for people with Celiac disease or severe gluten intolerance. For a gluten-free option, you can look for sourdough made from sorghum, quinoa, or buckwheat.

Since sourdough is often homemade, there's a risk of contamination during yeast development. Always discard the starter yeast if it shows signs of contamination, such as lack of bubbling, spots, or an unusual appearance.

Sourdough bread can be a safe and beneficial choice for your diet. If you have any questions about nutrition, you can consult a doctor via the consultation feature on the Ai Care app, available for download on the App Store or Play Store.
