Professional Bakers: Certification In Baking As Lifestyle Medicine

Inspiring change

30 March 2022 by Dr Vanessa Kimbell
organic garden
‘When we say from soil to slice we mean it, because I’m an environmentalist at both macro and micro scale.’ – Vanessa Kimbell

The Sourdough School gardens

We grown our botanicals that we use in the flour we mill in our organic gardens.

At The Sourdough School, we have a kitchen garden and a fruit garden. These walled gardens are set in rural Northamptonshire in the home of Vanessa Kimbell, covering two-thirds of an acre. These beautiful Victorian walled gardens are now in their eleventh year. We are deeply proud that we’ve been certified organic here for about seven years. It is in these gardens that we gather our botanicals, which we mill into the flour in our classes. Any spare botanicals, we dry and send to the mill at Hodmedods to include in our flour there.

There are examples of wheat from our population programme growing in the garden. We grow all our own botanicals, including all the flowers and petals we include, as well as the organic herbs. We have our own organic chickens, and try to grow all our salads and some of the vegetables we serve for lunch here at the School. Our fruit bushes are used to make our jams for the compotes with their high polyphenols. Wherever possible, we meet the requirements of the BALM protocol and eating symbiotically, by eating food produced in our gardens.

It starts with the soil…

We had to reimagine how our bread could be created according to our guiding principle of making bread that nourishes. The starting point isn’t with the bread itself – it’s with the soil and the soil systems. This includes the way in which our bread-making ingredients are sourced, and the ways we work with farmers and the environment.

You might say that we’re environmentalists on both a macro and micro level, because not only have we considered the macro environment – the soil systems, the agricultural systems, the way in which we produce the diversity breads and the way that we teach here at The Sourdough School – but we’re also micro-environmentalists; the micro environment I’m referring to here is the gut microbiome.

The true cost of organic food

Being organic is fundamental to the practice of our values here at The Sourdough School. I’m not saying it’s an easy thing to do (it’s not!), and over many years, it has been suggested to me that it is not a viable way of looking at bread-making. It’s certainly true that many people who are struggling to make ends meet can’t afford organically-produced ingredients. But lack of affordability distracts from the true cost of using pesticides, herbicides, fungicides and ‘baking improvers’. This cost includes some very unpleasant chemical cocktails.

Throughout our years of research, we’ve seen this all add up to a compromise on the gut microbiome, on the environment and on diversity. There are huge conglomerates that grow grain on an unimaginable scale, and our entire food system is reliant on the petrochemical industry, which is completely unsustainable. Even if you dismiss the health concerns of the carcinogenic and gut-damaging aspects of conventional agriculture and bread-making processes, and even if you dismiss the very real concerns around the impact on our environment, you cannot dismiss the fact that this is an unsustainable practice for long-term global food security.

We really have to look beyond the financial cost of organic

While I appreciate that I’ve been told this unrealistic, I believe that systems change and understanding is actually possible. We have created examples of how this is possible through our partnerships and our own certification here at The School. We have to be pragmatic about our approach to bread, and there are always compromises to be made. I think it’s important, whenever there is decision-making or whenever there is the possibility of practising organic principles, to do that as part of our value system.

Todays live for diploma students will be on 'How t Todays live for diploma students will be on 'How to engage your patient in the lifestyle changes of the BALM' with @vanessakimbell 

In their 6pm live session, we help keep our students on track with the syllabus and discuss the application of Baking As Lifestyle Medicine to the 6 pillars of Lifestyle medicine, applying the research papers, application of the Research, and how this ties into prescribing, along with guest lecturers, discussions and sharing knowledge.

📆 The Sourdough School Clinic - Thursdays 8pm - for students of The Sourdough School 

✏️ 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.
