10 Healthiest Sourdough Breads on Grocery Shelves, According to Dietitians

Navigating the bread aisle in a grocery store can feel incredibly overwhelming, especially if you're looking for the healthiest option on the shelves. With dozens of choices out there—from whole grain to white—and lengthy ingredient lists, deciphering what to look for when it comes to your health can leave you puzzled.

Amidst these countless options, sourdough bread stands out as a great choice. While sourdough can be made with refined flour, which tends to lack fiber, its natural fermentation process results in additional health benefits as well as an enhanced flavor and texture compared to most store-bought breads. While most store-bought breads use fast-acting commercial yeast that speeds up the fermentation process, sourdough's long fermentation process breaks down gluten, which enhances digestibility; increases the availability of certain nutrients; and lowers the glycemic index, resulting in a slower release of glucose into the bloodstream.

To better understand the healthiest options on grocery shelves, we spoke to registered dietitians to find out their top choices for sourdough bread loaves. When picking out a sourdough loaf, our experts recommend looking for an option that is moderate to low in calories, a good source of fiber, and contains some protein.

How dietitians chose the best sourdough loaves on grocery shelves:

When it comes to choosing a healthy sourdough loaf, you'll want to consider a few qualities for your health.

• Calories: Total calories per slice are an important part of choosing a healthy loaf of bread. Depending on the brand, the ingredient list, and the thickness of each slice, most breads range from 70 to 250 calories per serving. This is important to consider if you are regularly incorporating bread into your routine.

• Fiber: Fiber is typically one of the most important aspects of choosing bread at the grocery store. However, the fiber content in sourdough bread is usually very low. You might have to go out of your way to find a higher-fiber loaf of bread that's made from wheat flour or has added sources of fiber mixed into the ingredients.

• Protein: Bread is mostly a significant source of carbohydrates, but whole grains also provide some protein which can contribute to its staying power for feelings of fullness. If you can find it, choosing a loaf of bread that has at least a few grams of protein per slice can help keep you longer in addition to the fiber content.
