Can Celiacs Eat Sourdough?

  • Baker’s Yeast Is Not Traditional
  • Sourdough and Celiac

Research suggests that people with celiac disease tolerate sourdough bread where the dough is fermented with a specialized sourdough starter in accordance with traditional methods.

Buyer beware! Most breads labeled as “sourdough” on the market today are anything but…

These fake sourdough breads typically contain yeast and/or a sweetener.

This is an easy giveaway clue that the bread is a phony and should be avoided if one seeks a traditionally baked loaf.

Baker’s Yeast Is Not Traditional

When baker’s yeast was first introduced in France as an alternative to sourdough starter in the mid-1600s, it was strongly rejected!

The scientist-noblemen of the day knew that it would negatively impact people’s health. When the Faculty of Medicine decided to formally examine the question, they banned its use. (1)

True sourdough bread does not contain baker’s yeast. Instead, a Lactobacilli-based starter culture is used.

In addition, authentic sourdough is baked at a lower temperature for a longer period of time.

These methods protect the integrity of the cereal grains and preserve nutritional value. 

What’s more, anti-nutrients such as phytic acid are eliminated, and gluten, that very difficult-to-digest plant protein, is significantly broken down.

As a practical bonus, sourdough bread stays fresh longer than yeasted bread.

Despite the initial rejection of baker’s yeast, the convenience aspect of quick-rise yeasted loaves resulted in widespread adoption over the last century.

It is no surprise, then, that the skyrocketing cases of gluten intolerance and celiac disease have risen in lockstep over the decades.

Why did pre-industrialized people groups consume gluten-containing breads with no digestive difficulty whatsoever?

Could it be that the traditional preparation methods were somehow protective?

Sourdough and Celiac

The peer-reviewed Journal of Applied and Environmental Microbiology researched this very question, publishing a study conducted in Europe that examined how celiacs tolerate true sourdough bread. (2)

Seventeen people suffering from celiac disease were given 2 grams of gluten-containing bread risen with either baker’s yeast or a Lactobacilli culture.  

Thirteen of the seventeen participants showed negative changes in intestinal permeability consistent with celiac disease. Four participants did not show any negative changes.

Then, all the study participants were given true sourdough bread fermented with a special Lactobacilli culture able to break down the primary amino acid building block that causes an immune response in people with celiac.

None of the study participants showed any negative changes in their intestinal permeability after consuming the bread baked using 30% wheat flour and a mix of oat, millet, and buckwheat flour.

The researchers’ conclusions were summarized as follows:

These results showed that a bread biotechnology that uses selected lactobacilli, nontoxic flours, and a long fermentation time is a novel tool for decreasing the level of gluten intolerance in humans. (3)

What I find interesting about the study is that even when the people who consumed the wheat bread baked with either baker’s yeast or a normal Lactobacilli culture, four (nearly one-quarter) did not show any negative changes to their baseline values of intestinal permeability.  

Did these people consume bread raised with a normal sourdough culture?

If so, perhaps even regular sourdough cultures would be sufficient for some celiacs to consume.

Certainly, most with simple gluten intolerance would find true sourdough bread to be easily consumed with no digestive distress.

It seems that the noblemen in the court of Louis XIV of France had it right all along.

Abandoning the traditional methods of bread preparation in favor of baker’s yeast would have disastrous effects on people’s health. 

Little did they know that their wisdom several centuries later would be termed “novel” by scientists in the biotechnology industry!

    I think it’s important to point out that the bread that caused no reaction was made with special culture that I’m assuming isn’t easily available and only contained 30% wheat, which was combined with gluten-free grains. This is great and a very positive finding for those who suffer with celiac or gluten intolerance, but it is NOT a green light to safely start eating gluten-containing sourdough bread. For those with gluten damage, even a small amount causes more damage and for those who have healed, they may not see side affects of damage for a while. I guess while this is exciting news, I’m also cautioning those who have been concerned about possible gluten sensitivities of one form or another (and if you have a compromised gut, gluten is going to be harmful whether you have the genes for celiac or not) to not rush out and start making or buying sourdough without first carefully considering the risks.

    Yes, we’d love a good, trusted sourdough starter/recipe as well. You’re full of wonderful information Sarah, continual thanks!

    Tested and didn’t work for me (mental health issues with gluten consumption – not confirmed celiac). I didn’t make it myself though, so perhaps… perhaps. I do better without eating “bread” on a daily basis though, so I’m not too eager to leap into it. One of these days maybe. Options are nice to have…

    I found out last summer that I am sensitive to gluten AND yeast, so sourdough seems to be a win-win option, I just haven’t had the guts to try it yet. I am planning on ordering a starter, though, and trying it with spelt. Luckily my hubby loves sourdough, so he doesn’t need convincing. Thanks for the post!

    Nourishing Traditions has a sourdough recipe in it. But I haven’t tried it yet.

    Fascinating to learn that traditional sourdough does not include yeast. It seems the further we get from the traditional food wisdom of our ancestors, the more trouble we get in.

    The natural, traditional foods are the best.

    This is a very interesting article because I follow the Know the Cause (Doug Kaufmann, The Fungus Link) diet to eliminate fungus and yeast as the cause of inflammation/disease in the body. The first phase eliminates ALL grain, but eventually you can have true sourdough bread. I’d always wondered why that type specifically was recommended and how to know if it was “true” sourdough or not. This article really clarifies it for me! I’m with all the previous comments that are asking for a recipe for how to make this. If anyone can share this, I’d be most grateful!
