Is sourdough bread good for you?

5 February 2021 by Dr Vanessa Kimbell
is sourdough bread good or bad?
It depends on the way your bread is made.  This is BALM Protocol Bread – the defines what healthy bread is. 

Whether sourdough bread is good or bad depends on many things. In the first instance the way your body responds to bread is personal to you. and as each bread is different, you will respond differently to different kinds of bread. this is my area of expertise and you can learn more about the personalisation of bread here. 

Is Sourdough good for you? 

I the video above I share 5 top reasons of how sourdough is good for you, but this is not any old sourdough – this is the sourdough that is made according to the BALM Protocol and this is where my research and work is game changer. 

The Sourdough Secret: Weight Management

Many experts advocate against consuming bread, branding it as detrimental to health. However, in my extensive experience in baking, teaching, and researching bread tells a different story. Sourdough bread stands out as a healthier option, particularly in managing weight sustainably. Unlike the transient results of yo-yo dieting, sourdough offers a satisfying taste while keeping you fuller for longer periods, aiding in weight control without the deprivation.

Mood Stabilisation with Sourdough

Sourdough’s impact extends beyond physical health to mental well-being. The even release of energy from sourdough consumption helps avoid the blood sugar spikes and troughs associated with mood fluctuations. This stability contributes to maintaining a balanced mood and overall good mental health.

Digestive Health Benefits

Sourdough’s fermentation process pre-digests the flour, making nutrients more accessible and increasing fibre content. My research delves into how this enhanced fibre benefits gut health, leading to reduced bloating and promoting regular, healthy bowel movements. This aspect of sourdough contributes significantly to digestive wellness.

The Calming Craft of Sourdough Baking

The act of making sourdough itself has been found to have therapeutic effects. Research conducted during the lockdown revealed that participants experienced notably lower anxiety levels when baking sourdough. This suggests that the process is not just about creating food but also serves as a calming and enriching practice.

Nutritional Enhancement through Fermentation

The long, slow fermentation process of sourdough unlocks an increased amount of vitamins and minerals in the bread. Compiling various studies confirms the nutritional superiority of sourdough over conventional bread, underscoring its role in a healthy diet.

Sourdough bread, with its myriad health benefits, is not just food; it’s a pathway to a healthier lifestyle. Here at The Sourdough School, we delve deeply into the science behind sourdough, substantiating its advantages. For more insightful information on baking nutritious, sustainable bread for you and your loved ones

You will discover that what makes sourdough good for you is not just fermentation but the way that the sourdough is made. It’s important to recognise that sourdough is a process – understanding this is essential  when working out whether or not your bread is real sourdough. A true sourdough loaf will have gone through a long, slow fermentation. This makes the bread more nutritious, as the body is able to access and utilise more of the fibre, vitamins and minerals contained within the loaf. The slow fermentation reduces the gluten load, which improves digestibility, and increases resistant starch, which controls blood sugar. With regards to real sourdough, white sourdough is only marginally better for you than non-sourdough breads. This is because white sourdough still doesn’t contain much fibre, which is what nourishes your gut microbes. To increase your fibre intake, you should aim to make loaves that contain wholegrain flour rather than being made entirely from white flour. Wholegrain flour has other benefits, too, such as including more B vitamins and magnesium, but it’s important to be mindful of where you source your wholegrain flour.

Why some sourdough is not good for you

Not all sourdough is good for you. Fake sourdough, however, can actually be bad for you. Often these ‘fake sourdough’ breads contain flavourings to give them a sour taste – a flavour that should have been achieved through a long, slow fermentation. Without this slow fermentation, the gluten remains intact, which means that eating the loaf can raise blood sugar levels and could be awful for sufferers of IBS and non-coeliac gluten intolerance. In addition, any fibre within the loaf is less accessible to the body due to this lack of fermentation, as are the vitamins and minerals.

The kind of sourdough loaf you consume, as well as how you enjoy it as part of a meal, can also affect how good or bad sourdough bread is for you, and how nourishing it is for your gut. You can explore different recipes on the Sourdough Club, going from basic loaves containing some wholegrain flour to advanced bakes using Botanical Blends and additional ingredients. You can also discover our symbiotic recipes, which are designed to work with your bakes to enhance their nourishing effect as part of a balanced diet.

Some simple facts: to consider if sourdough his good for you

  1. Enhanced Digestibility: Sourdough fermentation breaks down gluten, making it easier to digest than regular bread. This process can be particularly beneficial for individuals with gluten sensitivity (though not for those with celiac disease), as it reduces the bloating and discomfort often associated with gluten.

  2. Improved Nutrient Absorption: The lactic acid bacteria present in sourdough can neutralize phytic acid, a substance found in grains that inhibits the absorption of minerals. By reducing phytic acid levels, sourdough bread allows for better absorption of minerals such as iron, zinc, and magnesium, contributing to a more nutritious diet.

  3. Lower Glycemic Index (GI): Sourdough bread has a lower GI compared to many other types of bread. This means it causes a slower rise in blood sugar levels, making it a more suitable option for managing blood sugar, especially for individuals with insulin sensitivity or diabetes.

  4. Rich in Prebiotics and Probiotics: The fermentation process enriches sourdough with prebiotics, which feed the beneficial bacteria in the gut. Although most probiotics do not survive the baking process, the changes in the bread’s pH and the breakdown of fibers during fermentation can still benefit gut health.

  5. Natural Preservation: The acidic environment of sourdough bread acts as a natural preservative, helping to inhibit the growth of mold and extending its shelf life without the need for artificial preservatives.

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.
