Have you ever wondered about the health benefits of sourdough bread?

Sourdough is easy to digest, it’s gluten-sensitive friendly, and it has a ton of amazing nutrients inside. When you unpack the science behind sourdough, it gets really interesting!

But sourdough benefits go far beyond health. I’m so excited to go through 27 reasons why this nutritious bread, packed with beneficial bacteria, should find its way into your home.

What Is Sourdough?

The tradition of making sourdough is centuries old and traces back to ancient Egypt. 

“Traditional communities all across the world rarely ate whole grains without first fermenting or otherwise processing them to break down antinutrients that they contain.”

And it makes sense that it’s been around for so long since this bread is simple to make and packed with gut-friendly health benefits. 

Forget commercial yeast; sourdough relies on wild yeast and lactic acid bacteria for its unique tangy taste. With just flour, water, and time, you can create a homemade starter that transforms into flavorful, crusty loaves.

If you’re comparing different types of bread, it’s easy to see why sourdough is preferable. You can’t go back to storebought white bread after you’ve tried it!

No Chemicals or Preservatives

Commercial bread products, like white, wheat, and whole grain bread, often have a laundry list of additives to help preserve and add flavor. 

Sourdough has minimal ingredients – just flour, water, salt, and sourdough starter. Its unique fermentation process (which is not as complicated as it sounds) enhances the taste.

Why Sourdough Bread?

In recent years, the popularity of sourdough bread has skyrocketed, mostly because of COVID-19. We were all home with nothing to do!

But along the way, we’ve discovered just how many benefits sourdough bread has.

One study reviewed 25 clinical trials and found that overall, “in studies using specific strains and fermentation conditions, significant improvements were observed in parameters related to glycemic response, satiety, or gastrointestinal comfort after bread ingestion” (“Nutritional benefits of sourdoughs: A systematic review,” 2023).

There really is something special about sourdough!

Let’s dive into all the things that make sourdough so great for you.

Practical Benefits of Sourdough Bread

1. Incredible flavor

I’d be remiss if I didn’t start out this list with just how incredible sourdough bread tastes!

Sourdough’s unique tangy flavor comes from the microbial community in the bread. Lactic acid can contribute to a yogurt flavor, while acetic acid can add a sharper, more vinegary note. 

Conventional bread has a pH level of around 6, but sourdough has a lower pH, around 3.5 to 4.5 – that’s what contributes to that sour tang.

To get a bit more technical, here’s how flavor forms in sourdough:

“The formation of flavour volatiles in sourdough is contributed by proteolytic processes of amino acids, conversion of glutamine released from cereal proteins to glutamate, and conversion of arginine to ornithine by LAB during baking which have a profound influence in a more tangy and roasty sourdough taste.”

“Sourdough Microbiome Comparison and Benefits,” 2021

The types of flours you use in your dough can also contribute to added flavor (I love doing a combo of bread flour, rye flour, and whole wheat flour).

If you haven’t tasted sourdough, you’re in for a real treat.

2. Cost-effective

While there is a time investment, monetarily speaking, sourdough is very inexpensive to make. It’s fun to have all the cool sourdough equipment, but you don’t need it to create an amazing loaf of bread.

Sourdough ingredients are only water, flour, salt, and sourdough starter. You can make a sourdough starter with flour, water, and time, but I highly recommend buying it from a local baker or seeing if a friend will give you some. That shouldn’t cost you more than $10-$20.

For me, the cost of feeding my starter and baking two loaves of bread per week is less than $5. And I also get to make all kinds of fun recipes with my sourdough discard!

3. Great protection against spoilage

Sourdough bread doesn’t spoil as fast as bread made with commercial yeast.

Thanks to the acidic environment, there’s a huge reduction in the development of harmful microbes, which means your bread won’t mold nearly as fast as other fresh breads.

In my experience, a loaf of sourdough can be stored on the counter for at least five days before it starts developing any signs of mold. And remember – this is bread with NO preservatives in it!

4. Less likely to go stale

In addition to having great protection against spoiling, sourdough bread is far less likely to go stale.

That’s thanks to the decomposition of starch during lactic acid fermentation. It’s all a bit scientific, but the end result is bread that lasts! And if you’re going through all the effort to make a loaf, that’s a practical benefit.

5. Sustainable alternative

Buying bread from the store comes with all the packaging, likely including plastic.

When you bake your own sourdough bread at home, you cut out all that unnecessary packaging. Plus, you avoid all the chemicals and preservatives!

6. Customizable recipes

One of the coolest parts of maintaining my own sourdough starter is that I can make bread and recipes that you literally cannot buy.

Sourdough bagels with asiago everything seasoning? Uhh, yes! Sourdough chocolate chip scones? Mmm.

Sourdough bread made with a combination of different flours, honed down until it’s exactly how I like it? Definitely.

Sourdough is completely customizable, and you are in total control.

Nutritional Value of Sourdough Bread

7. Digestive friendliness 

Sourdough bread can be easy to digest for many people. 

According to a study on sourdough microbiomes, the lactic acid bacteria in sourdough is incredibly beneficial to our digestive system. This is because of lactic acid bacteria and yeast. 

The combination creates a digestive-friendly environment that helps break down proteins, starches, and fats, making it a great choice for digestive well-being.

8. B Vitamins 

A loaf of sourdough includes a lineup of B vitamins, like B1, B2, and B6. These vitamins make sure your body’s metabolism runs smoothly. 

So if you’re at the grocery store deciding between whole wheat, rye, or sourdough bread, remember that choosing sourdough includes the B vitamins your body needs.

9. Gluten-sensitive friendly

Sourdough bread might be a friendlier option for those with a gluten sensitivity. 

The special fermentation process gives gluten a bit of a pre-digestion, making it easier on the stomach. 

According to this study, sourdough fermentation significantly decreased the gluten content in bread. So, if you’ve been feeling uneasy with regular bread, give sourdough a try as a tastier and more digestible choice for you. 

Some people with celiac disease or a gluten intolerance can tolerate sourdough bread if it goes through a longer fermentation (“Sourdough Microbiome Comparison and Benefits,” 2021).
