How does Sourdough particularly help support the gut microbiome?

24 January 2018 by Vanessa Kimbell
digestion poster in sourdough school
I think it is fair to say that, the collective evidence from the studies showing  increased levels of fibre and levels increased bioavailability of polyphenols,  contributes to supporting our gut microbiome.

I wrote a feature recently on polyphenols and sourdough. The evidence suggests that the long slow fermentation increases bioavailability  of these beneficial antioxidants .. which in turn is good for our gut microbes, and protecting against a range of diseases.. but it got me thinking about the other benefits of long slow fermentation in relation to our gut microbiome, and I thought it might be a good idea to summarise the main points. Although large-scale clinical trials on the effects of sourdough baked products on health and nutrition in humans are limited, the information so far still seems valuable. Examples include, fermentation and acid production by lactic acid bacteria and yeast have been shown to bring about improved mineral and polyphenol bioavailability – especially in those made with wholegrain flour. Sourdough baking is also consistently shown to deliver breads with higher levels of resistant starches and the lactic acid bacteria fermentation increasing the overall fibre content of sourdough breads. Sourdough can help increase your dietary fibre intake by 10-15% and the ratio of soluble to insoluble fibre can be manipulated depending on how long you ferment your dough. Recent advances in the area of gut health has shown that phenolic compounds { LINK } in addition to fibre has been shown to improve gut microbial diversity which is pivotal in maintaining a healthy gut microbiome.

In addition to polyphenols, ( a source of food for our gut microbes) sourdough breads made with wholemeal flour also provide fibre which is beneficial in prevention and management of constipation and is of importance in the management of other large-intestinal diseases such as irritable bowel syndrome and bowel cancer. There is over 50 years of research documenting how fibre consumption has been linked to body weight reduction and maintenance, and there is a mountain of evidence that supports the fact that getting enough dietary fibre helps contribute to reduced risk of an array of diseases including type 2 diabetes.

In sourdough however there is another level of benefit as the dough ferments. The lactic acid bacteria produce extracellular polysaccharides called exopolysaccharides, which could also act as a source of fibre for our gut microbiota.

I think it is fair to say that, the collective evidence from the studies showing  increased levels of fibre and levels increased bioavailability of polyphenols,  contributes to supporting our gut microbiome.

✏️ In this weekly live session, we cover technical baking questions. Students can submit their Baking Record Sheets in advance of the session.

📋 We look at the details of our student's bakes - the specifics of the flour, timings and temperatures. Using our sourdough record sheets Vanessa will make suggestions on how they might modify, or recalibrate the next time they bake.

IBS AWARENESS MONTH Do you suffer from irritable IBS AWARENESS MONTH

Do you suffer from irritable bowel syndrome (IBS)? It can be tough to deal with the uncomfortable symptoms of stomach cramps, constipation, diarrhoea and bloating. But did you know that making dietary changes, such as incorporating sourdough bread into your diet, could help alleviate some of those symptoms?

Studies have shown that sourdough's long, slow fermentation process can reduce IBS symptoms. Plus, during #ibsawarenessmonth, we're exploring how adding different herbs and spices to your sourdough can further improve both the flavour and the digestion of your bread.

Let's talk about gut health, fermentation, and how sourdough can be a delicious and healthy addition to your diet. Join the conversation and share your experiences with IBS and sourdough.

THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME

One of the biggest issues around using a plastic lame to score sourdough, of course, is that eventually the blade will become blunt and the lame could end up in landfill.  So several years ago I talked to my dear friend EJ about developing a lame with a replaceable blade. And he came up with this very beautiful hand carved wooden lame.

Very sadly EJ is no longer with us. Recently a friend of EJ’s who is also a wood turner and carver offered to make these again for us in remembrance of our dear friend.

The Baking As Lifestyle Medicine (BALM) Protocol The Baking As Lifestyle Medicine (BALM) Protocol

The current food system is broken at multiple levels, from the pesticides used in our soils to the emulsifiers and additives adulterating industrially-processed foods. Nowhere is this more apparent than in the bread we eat.  The figures reported by the UK Flour Millers say that bread is bought by a staggering “99.8% of British households” and that “the equivalent of nearly 11 million loaves are sold each day. Approximately 60-70% of the bread we eat is white and sandwiches are thought to account for 50% of overall bread consumption. Average bread purchases are the equivalent of 60.3 loaves per person per year.” 

Most bread sold is made by modern processing methods that strip heart-healthy whole grains of their nutrient contents, resulting in low-fibre bread with a high glycemic index. Over time, white processed bread can increase a person’s risk of insulin resistance alongside other lifestyle diseases.

We’re on a mission to revolutionise the bread making process at every level – from soil to slice. The rules governing this are laid out in our Baking As Lifestyle Medicine protocol.
