Heath Care Providers: Training In Prescribing Baking As Lifestyle Medicine

Translating Research into products

17 December 2022 by Dr Vanessa Kimbell

Product development: Botanical Blend flour is systems change on multiple levels.

We create change through supporting gut health and equality in food and the environment. Our mission is to reform the bread-making process at every level, from soil to slice.  The foundations of baking sourdough are flour, salt, water and fermentation. It’s simple, but there is a fundamental flaw in this principle: the flour. Most commercial flour is based on monoculture, so on a macro level, baking using Botanical Blend flour is a powerful act of delicious defiance against the global industrialisation of our most basic food. It is an absolute rejection of monoculture. It is also, however, a wonderful example to the food industry of what could be done to improve food systems.

Base Blend No. 2: Meadow Blend Flour is the foundation of our Systems Change Programme, and it’s also our signature blend at The Sourdough School. It was the very first Botanical Blend flour to be launched and made available for sale via Hodmedods, who produce it for us. This is our base blend, made with spelt, einkorn, emmer, barley, naked oats, poppy seeds, buckwheat, linseed, dried peas, dried edible meadow flowers, cornflower, mallow flower, rose petals and dried nettles. That means at least 14 different ingredients in every slice of bread you eat that is made with our diversity flour. Rethink flour: this is baking as activism.

Funding social equality from the proceeds of our flour.

There is no magical pill to reverse the damage created by eating a poor diet, which is linked to multiple adverse health conditions and mental health issues. Our graduate GPs and healthcare professionals are very limited in what they can do to combat poor diet when patients present with illnesses related to it. The Baking as Lifestyle Medicine (BALM) dietary interventions had such an amazing impact on participants in our dietary intervention studies that we realised that baking is a revolutionary way to support social change and support both physical and mental health. So, as part of our Systems Change Programme, our healthcare graduates are able to prescribe bread-making as a social prescription. To help support this, all the profits from the sale of Blend No. 2 are converted to vouchers that doctors may prescribe at their discretion for ingredients or kits to accompany the online Baking as Lifestyle Medicine Prescription Membership.

Supporting regenerative, sustainable agriculture.

The current system is complicated, and both farmers and millers are trapped in an industrial system. This flour an is an example of regenerative and cooperative agricultural practices, which can empower bakers and patients to bake as activism.

Flour that supports diversity in the gut microbiome.

Using just one ingredient goes against our core aim at The Sourdough School, which is to bake to nourish the gut microbiome. While there is still much to be discovered about the microbiome, all the research points over and over again to a simple fact: the wider the diversity of your gut microbiome, the more robust your health. This research is irrefutable; eating a diverse range of plants is one of the key factors affecting gut health. Therefore, achieving diversity in our most basic of foods, bread, is central to our research here at The Sourdough School. The Botanical Blend flour is central to the second principle of our BALM Protocol: increasing diversity in your diet. On a micro level, this is about nourishing and delivering the diversity of fibre to optimally nourish your gut microbiome.

    So Vanessa, Eloise’s daughter has just been told she has an intolerance to all wheat products, I’m wondering whether this flour would enable her to eat bread without tummy aches, and how do I get it for her. We don’t live far from Northampton. It sounds good for me too.

      Hi Margaret apologies for the delay. As long as she definitely doesn’t have celiac disease then she could try any authentic sourdough bread and see how she gets on. It is the fermentation process that makes sourdough bread easier to digest. Perhaps start with a white sourdough and then slowly increase to increasing percentages of wholegrain sourdough. If making sourdough yourself the longer you ferment it for (ie tin loaves) the more easily digestible it is. Hope she gets on really well with it 🙂

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.
