Can Bread Be Anti-Inflammatory? A Closer Look at Whole Grains and Sourdough

October 22, 2025 •

3 min read

According to a 2022 systematic review, swapping refined grains for whole grains can significantly reduce inflammatory markers in the body. The question of whether bread can be anti-inflammatory largely depends on its ingredients and preparation, with different types having drastically different effects on the body.

Quick Summary

Refined white bread can promote inflammation due to its high glycemic index, while whole grain and genuine sourdough options can offer anti-inflammatory benefits from fiber and other compounds.

Key Points

Refined Bread is Pro-inflammatory: White bread and other refined grain products can promote inflammation due to their high glycemic index and lack of fiber.
Whole Grains Offer Anti-inflammatory Benefits: The fiber, vitamins, minerals, and antioxidants in whole grains help regulate blood sugar and support a healthy gut, reducing inflammation.
Sourdough Fermentation Improves Digestibility: Natural sourdough's fermentation process results in a lower glycemic index and potentially enhanced nutrient bioavailability, with gut-friendly prebiotics.
Gluten Matters for Sensitive Individuals: While not inherently inflammatory for most, gluten must be avoided by those with celiac disease or non-celiac gluten sensitivity to prevent an inflammatory response.
Overall Diet is Most Important: The impact of bread depends on the larger dietary context. Pairing healthy breads with other anti-inflammatory foods like fruits, vegetables, and healthy fats is key.

The Problem with Refined Bread and Inflammation

Many common breads, particularly white bread, can contribute to inflammation. The refining process removes the bran and germ, leaving primarily the starchy endosperm. This results in a high-glycemic food that causes rapid blood sugar spikes, potentially triggering inflammation over time. Refined grains also lack sufficient fiber, which is essential for a healthy gut microbiome that helps control systemic inflammation. Additionally, some commercial white breads contain additives that can negatively impact gut health.

The Case for Anti-Inflammatory Bread

Breads made from whole or sprouted grains, and those produced via natural fermentation like sourdough, can offer anti-inflammatory properties.

Whole Grains and Their Protective Components

Whole grain bread uses the entire grain kernel, retaining fiber, phytochemicals, antioxidants, vitamins, and minerals that are lost in refined grains. Fiber helps prevent blood sugar spikes and feeds beneficial gut bacteria, crucial for controlling inflammation.

Sourdough Bread: A Fermented Advantage

Genuine sourdough bread's fermentation process can improve the glycemic response compared to standard bread. It may also enhance the bioavailability of certain minerals by breaking down phytates. While most probiotics are killed during baking, sourdough contains prebiotics and postbiotics that support gut health and may have anti-inflammatory effects.

Sprouted Grains and Alternatives

Sprouted grain breads, like Ezekiel bread, are considered anti-inflammatory as sprouting enhances nutrient availability and digestibility. Alternative flours like spelt and buckwheat can also be suitable for those who tolerate them.

What About Gluten?

For most people, gluten itself is not inflammatory. However, individuals with celiac disease or non-celiac gluten sensitivity must avoid gluten as it triggers inflammation.

Making Smart Bread Choices: A Comparison

Making informed choices requires understanding how different breads impact inflammation. Here's a comparison:


Feature	Refined White Bread	Whole Grain Bread	Genuine Sourdough Bread	Sprouted Grain Bread
Key Ingredient(s)	Processed white flour (endosperm)	Whole grain flour (bran, germ, endosperm)	Fermented whole or white flour, water, salt	Sprouted whole grains, legumes
Fiber Content	Low	High	Higher than white, can vary	High
Glycemic Index	High, causes rapid blood sugar spikes	Lower than refined bread	Lower than refined bread	Low
Inflammatory Impact	Potentially pro-inflammatory due to blood sugar spikes and gut disruption.	Anti-inflammatory due to high fiber, antioxidants, and nutrients.	Anti-inflammatory via improved digestibility, lower GI, and gut health benefits.	Anti-inflammatory; sprouting enhances nutrient bioavailability and digestibility.
Nutrient Profile	Low, nutrients often added back synthetically.	High in fiber, vitamins, minerals, and polyphenols.	Enhanced mineral absorption due to lower phytate levels.	Very high, sprouting makes nutrients more available.

Beyond the Loaf: A Holistic Approach

Bread choice is just one aspect of an anti-inflammatory diet, which emphasizes diverse nutrient-rich foods. These include fruits, vegetables, fatty fish, nuts, seeds, legumes, and healthy fats like olive oil. Combining healthy bread with these foods enhances the anti-inflammatory benefits. For more information on whole grains and inflammation, the Whole Grains Council is a valuable resource.

Conclusion

In summary, the anti-inflammatory potential of bread depends heavily on its type. While refined white bread can promote inflammation, whole grain, sprouted grain, and genuine sourdough breads offer beneficial fiber, antioxidants, and improved glycemic responses that contribute to an anti-inflammatory diet. These choices support gut health and overall well-being. Individuals with celiac disease or gluten sensitivity must opt for gluten-free alternatives to avoid triggering inflammation.

Frequently Asked Questions

White bread is made from refined flour, which has a high glycemic index because the fiber-rich bran and germ are removed. This causes rapid blood sugar spikes that can trigger an inflammatory response over time.

While the sourdough starter contains probiotics, the high heat of baking kills most of these live bacteria. However, the bread contains beneficial prebiotics and postbiotics that support a healthy gut microbiome.

Yes, whole grain bread is a good anti-inflammatory option because it contains fiber, vitamins, minerals, and antioxidants that help regulate blood sugar and support gut health.

No, individuals with celiac disease should not eat sourdough bread made from wheat, spelt, or other gluten-containing grains. Sourdough fermentation does not eliminate gluten and would still trigger an inflammatory immune response.

Yes, other types include sprouted grain breads (like Ezekiel bread), which are nutrient-dense and easy to digest, and breads made from ancient grains like spelt or buckwheat, which can also be beneficial.

The fiber in whole grains feeds the 'good' bacteria in your gut, acting as a prebiotic. This supports a healthy gut microbiome, which is strongly linked to reduced systemic inflammation.

Look for breads that list '100% whole grain,' 'sprouted grains,' or 'wholemeal flour' as the first ingredient. Avoid products with 'enriched flour,' added sugars, or long ingredient lists with preservatives.
