Q & A for the Diploma in Nutrition & Digestibility of Bread & Course Overview

2022–2023

This is the Q & A for The Nutrition and Digestibility of Bread Course.

Is there any more detailed information about the course?

Yes.  You can Download the full Sourdough Prospectus 2022–23 here.

Who is this course for?

The course appeals to healthcare professionals and bakers who are interested in understanding the impact of bread on the gut microbiome, and the subsequent effect this has on physical and mental health. Past attendees have included general practitioners, hospital specialists, nutritionists, dieticians, nutritional psychiatrists, and bakers who teach or who are community-focused and want to change their approach to the products they bake and sell.

Who teaches this course?

The Course Director is Vanessa Kimbell, but the course itself is taught by our multi-disciplinary team and by guest lecturers who have specific expertise in certain areas, including Professor Tim Spector, Professor Felice Jacka and Dr Micheal Mosley, to mention a few.

Can I speak to Vanessa about my circumstances?

Yes. In fact, Vanessa chats with all students before they are accepted on the course as part of the application process, but you can also book an informal chat with Vanessa in her open clinics, which are held on Friday afternoons, by filling out this form.  You may need to wait a week or two, but it is really important to make sure that your personal needs are aligned with what we teach and the way we teach it before you commit.

Course overview

The programme is run by Vanessa Kimbell and the team at the Sourdough School, sharing her research and unique approach to the nutrition and digestibility of bread, and nourishing the gut microbiome. The syllabus, which is delivered to you each month, is a living syllabus made up of lectures, guided learning, tutorials, tasks and live videos. It is taught by some of the world’s leading experts and includes recipes, studies, supporting materials and a Sourdough Clinic.

Why is this course so different?

It is interactive.

You become part of a community when you enrol, receiving a Community Membership to the Sourdough Club as a part of your course. Not only that, but you will also study and understand the science behind baking and nutrition, and then put it into practice with our sourdough method and recipes. This course is deeply engaging, as the knowledge you learn will be applied to and embedded in your lifestyle, resulting in an innate understanding of the ways in which we are impacted by the food we eat every day.

It is revolutionary.

This course is part of our Systems Change Programme. It doesn’t just teach you; it empowers you. The syllabus includes built-in tasks that will change the way you bake, eat and connect to your bread and food for life.  Furthermore, if you are a healthcare professional, then upon completion, you will be issued with a Practitioners’ Prescription Licence, enabling you to prescribe our short courses to your patients as a free social prescription in preventative medicine.

We will be studying every aspect of bread, covering everything from the industrialisation of agricultural systems and the rise of monoculture to the impact of a diet high in refined, processed carbohydrates on both physical and mental health.

We will take a close look at the evidence around organic systems, wholegrains and the importance of diversity in supporting gut health. We will also examine the mechanisms of how sourdough transforms bread, and discuss the ways in which this impacts health. You will learn how bread can reduce bloating, support gut health, help manage weight, balance blood sugar, improve mood and positively impact other aspects of health and wellness.

Q & A for the Diploma in Nutrition & Digestibility of Bread & Course Overview

How does the course run?

The course follows an academic term structure comprising three terms between September and July. It consists of two modules that run side by side. Live sessions are held on Thursday evenings and recorded, allowing you to catch up later if you live in a different time zone. One-to-one sessions are bookable on Friday afternoons, and the whole syllabus is online.

How do I learn?

There are many different ways to learn on this diploma course. There is a timetable of different self-guided topics, and we run weekly clinics, as well as holding live lectures that accompany the self-guided part of the course. There are also guest lecturers, ‘in conversation’ video features, in-depth articles, tasks and, of course, baking, for which you will use the studies that underpin our Bread Protocol as you make your bread and baked goods.

The diploma consists of the following modules, which are explained in more detail below:

  1. Bread & Guts: The Impact of Bread on the Body & Mind
  2. The Bake for Health Certificate, where we apply the research learned on the Bread & Guts module to our recipes
  3. Optional  –  A One-Week Nutrition & Digestibility of Bread Workshop at the Sourdough School, which offers you the chance to attend the School in person to bake with the team, consolidate the knowledge you’ve learned on the course and cement the learning.

Please note that these are living syllabi – we review the syllabus each quarter as new research comes out, and update it with the latest findings. 

How much time will this course take?

The course requires a minimum of two hours a week, but if you engage fully with the recommended baking and reading, then you should expect to spend about six hours a week on the course.

Is the course accredited?

We are currently working on re-accrediting the Bread & Guts module of this course. We will update this information when we have finalised accreditation.

Are there any discounts available?

Yes – please see The Sourdough School Awards Programme.

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.
