How to fix your relationship with bread
I’m Dr Vanessa Kimbell — the first person in the world to hold a doctorate in Baking as Lifestyle Medicine and Preventative Healthcare. A lifetime ago, I was a time-served artisan baker, returning from France, who stopped being able to eat bread. That’s when I asked what no one else thought to ask: why was the fast, fibreless bread we ate every single day slowly harming us — and what if the opposite was the truth? What if slow-fermented, wholegrain diversity sourdough optimally supports our health? It does. This is where I share that, challenge you to think differently, and inspire you to bake, eat and share Proven Bread.
You can explore that further at The Sourdough School, or book a 1:1 meeting to get your bread personalised.
Whether you’re reading one of my books, or a feature, following a recipe, or you have stumbled across this page on a google search, you may encounter some unfamiliar terms, especially if you’re new to baking. I often write about health and lifestyle medicine alongside my recipes and articles. I believe that knowledge is empowerment, and I never want to oversimplify or water down the information I share.
Too often, we assume people don't want deeper insights, but I believe that understanding the ‘why’ and ‘how’ behind baking leads to better, more intentional choices. The purpose of this glossary is to ensure that everyone—regardless of their background or level of baking experience—has equal access to the knowledge they need to bake bread that is not only delicious but deeply nourishing.
It’s not just about making bread; it’s about making sure that the people you bake for are nourished, ensuring that the bread you bake possibly impacts you, and is full of nutrients and made with purpose and care. So this glossary has been created so I can share that knowledge as generously and widely as possible in the hope that you will, in turn do the same.
Please get in touch if you have any suggestions for additions.
Kind regards
Dr Vanessa Kimbell
