Is Sourdough Bread Good for You?

Crunchy on the outside, soft and slightly tangy on the inside, sourdough bread is one of our all-time faves for so many reasons. Have you had sourdough French toast? It’s life-changing. So yes, it’s delicious, but is sourdough bread good for you? We asked a nutritionist not to break our hearts and boy, did she deliver.

How is sourdough different from other breads?

You know that tangy sourdough taste? That comes from a fermentation process, which begins with a sourdough starter, a combination of flour and water. Starters are to sourdough what a packet of yeast is to other breads—you need it to make the bread rise. But you typically can’t just buy a starter at the grocery store; starters are made at least a week before the actual baking of the bread to give live cultures (aka good bacteria) time to develop. The naturally occurring lactobacilli and yeast release lactic acid and carbon monoxide which adds to the flavor, shape and rise of the bread—they’re also what actually make sourdough bread pretty healthy for you. One of the coolest things about sourdough starters is that they can last a really, really long time (decades) as long as you keep feeding it. Yep, “feeding” the starter flour keeps the bacteria alive and kickin’. Some families and bakeries pass their starters down for generations!

What are the benefits of sourdough bread?

Bread hasn’t had the best rap the last few years (thanks, Keto diet), but there are actually many nutritional benefits to sourdough.

1. Fermented bread is good for gut health

Sourdough is fermented and, as Stacey Krawczyk, M.S., R.D points out, this is one of the main reasons we can call the bread healthy. When the starter ingredients in the sourdough are mixed and left to sit, lactobacillus (the good bacteria) breaks down and creates lactic acid which helps your gut better absorb the many nutrients in the bread.

2. Sourdough has folate

Folate is a B vitamin that’s particularly beneficial for pregnant women because it’s “most associated with preventing neural tube (the pre-central nervous system in a fetus) defects during early pregnancy,” Krawczyk says. Folate is also super important for heart health and about half of the amount we need in a day can come from a thick slice of sourdough. Mmm.

3. It’s rich in essential minerals

Sourdough is rich in thiamin and niacin, both of which can boost your metabolism. It’s packed with iron for oxygen flow; zinc for your immune system; and magnesium and calcium for bone, muscle and nerve health. Whoa.

4. Whole-grain sourdough is even better for you

Krawczyk says adding whole wheat flour to your sourdough recipe (either as 100 percent of the flour or as a blend with white bread flour) will add even more of these vital minerals, help control your cholesterol levels and can aid in weight management.

5. Add seeds for more health

To beef up that health factor even more, you can add seeds (like sesame or pumpkin) and grains (like quinoa) to the dough while kneading or as a last-minute sprinkle on top before it goes into the oven for an added protein and fiber one-two punch.

Are there any negatives to sourdough bread?

When sourdough is kneaded, it isn’t punched down like many others are, allowing it to retain a lot of air pockets within the dough. This lighter touch creates an airier texture—but this can lull you into a false sense of security. Sourdough is still a carb that you shouldn’t overindulge in, especially if you’re watching your waistline. No matter how light it might taste. “The most important thing is sensible portions and balance,” says Krawczyk, who recommends building a better sandwich with lettuce, sliced fresh tomato, lean roasted chicken breast for protein and healthy fats from avocado.

How to make your own sourdough bread

Making sourdough is a commitment that you have to plan out days in advance, but you got this! To make it, you have to have a starter on hand—one that’s been fermenting for a week. Food blogger Alanna Taylor-Tobin’s tricks and tips for making a starter and her recipe for sourdough bread from her site, The Bojon Gourmet, are below.

This recipe makes one loaf, or 12 servings, and has 142 calories, 231 milligrams of sodium, 28 grams of carbs, 2 gram of fiber, 1 gram of sugar and 5 grams of protein per serving.

Starter Ingredients:

  • ½ cup whole wheat flour
  • ¼ cup water

Directions (by day):

Day 1 – Mix ingredients in a jar with a spoon. Cover loosely with plastic wrap and let it rest in a warm spot, about 75-80 ºF, for 24 hours.

Day 2 – Check your starter for bubbles—even a couple will do! If you see a thin layer of dark liquid sitting on the top of your starter, skim it off. This is the “hooch,” and it’s not what we want in our bread. Cover again and leave it be for another 24 hours.

Day 3 – On the third day, your starter needs to be fed. Remove the top half of the starter from the jar and throw it out. Add ½ cup of flour and ¼ cup of water to the jar and mix it all up with the remaining starter with a fork. Cover and store in a warm place again for another 24 hours.

Days 4 – 6 – On days four, five and six, you’re going to repeat day three’s step. Don’t forget to skim and discard the hooch every time.

Day 7 – Your starter should be double the size it was the last time you checked on it, bubbly and the texture of a roasted marshmallow—nice and gooey. If not, you have to spend a few days more on the feeding process. Be patient, it’s worth it!

At this point, you’ve birthed a starter that you can take from and feed for years to come. Literal years. To test it and make sure it’s ready to use, drop a teeny dollop into a glass of water. Is it floating? Great, you’re ready to bake.

Sourdough Bread Ingredients:

  • 12 oz. sourdough starter, active, bubbly and ready to go (about 1 ½ cups stirred down, or 3 cups at full froth)
  • 8 oz. room temperature or lukewarm water (1 cup)
  • 1 oz. wheat germ (1/4 cup)
  • 5 oz. whole wheat bread flour (1 cup)
  • 8 – 10 oz. white bread flour (1 2/3 – 2 cups)
  • 1/4 oz. sea salt (2 1/4 teaspoons)

Directions:

1. Stir all ingredients together in a large bowl until a rough dough forms. Add more bread flour if your dough is very wet.

2. Scrape the dough out onto a lightly floured surface. Invert the empty bowl over the dough and let it rest for 20 minutes.

3. Remove the bowl and knead the dough vigorously for about 10 minutes—adding as little flour as possible to prevent the dough from sticking to your hands and the surface—until it feels smooth, springy and elastic.

4. Place the dough in a large, lightly oiled bowl. Cover tightly with plastic wrap and allow it to rise until doubled, three to four hours. The warmer the spot you choose, the faster it will rise, the ideal temperature being 75-85ºF. You can also let the dough rise in the fridge or a cool place overnight.

5. Dough should be doubled in size. Gently turn out onto a lightly floured surface. Tuck the edges underneath itself then and gently rotate the dough on the surface to form a taught outer layer of dough. It’s called a boule,

6. Place the boule directly on a peel or board dusted with flour then slip the whole thing into a large plastic bag. Close the bag with a twist-tie or clip while trying to preserve as much air inside of the bag as possible. Let the bread rise until doubled, about 1 ½ – 2 hours.

7. While the bread is rising, place a baking stone on the rack (or a heavy-duty baking sheet), and place a metal pan that you don’t care about sacrificing (it will get rusty) on the floor of the oven. Crank the oven up to 500ºF.

8. Poke the bread with your finger and see if the indentation holds. If so, you’re ready to bake! Gently turn it out onto a wooden peel dusted with flour. Fill a cup with ice cubes. Quickly slip the boule off the peel and onto the stone and toss the cubes onto the hot pan on the floor of the oven. This will steam the outside of the loaf, allowing it to expand as it bakes.

9. Bake 20 minutes, then turn the oven down to 450ºF and bake another 20 minutes or so, until the bread is a deep, golden-brown. An instant read thermometer inserted into the middle should read 210ºF, the temperature at which the dough is set.

10. Let cool completely on a wire rack, one to two hours, before enjoying. And you will enjoy!

Bread is best fresh but will keep in a paper bag at room temperature for up to 3 days.
