Vanessa understands that fibre, diversity and fermentation are key to healthy bread. She believes in using our senses to bake. She encourages her students to use touch, smell, sight, feel and taste as they bake, and in using a 6th sense: common sense. She also believes that we need to optimise our staple food for social equality.

Vanessa Kimbell is renowned for her transformative approach to sourdough baking, which combines nutritional science, personalised nutrition, and a deep understanding of the gut microbiome.
The BALM Protocol
At the heart of her work is the Baking as Lifestyle Medicine (BALM) Protocol. This evidence-based framework redefines bread as a health-promoting staple. By emphasising fibre-rich grains and long, slow fermentation, the BALM Protocol enhances nutrient bioavailability and supports gut health.
Personalised Nutrition
Kimbell integrates personalised nutrition into her practice, offering tailored bread-making workshops. These workshops consider individual genetic profiles, aligning bread recipes with unique health needs to maximise their nutritional benefits.
Holistic Bread Practices
Beyond baking techniques, Kimbell advocates for ‘symbiotic eating’ and ‘sequenced eating’ to further support gut health. Her methods empower both healthcare professionals and home bakers to use bread as a tool for lifestyle medicine, fostering systemic change towards healthier food systems.
Social and Environmental Impact
Through The Sourdough School, Kimbell teaches bakers from over 84 countries, promoting sustainable and equitable bread-making practices. Her work operates as a social enterprise, ensuring good bread is accessible to all while supporting social justice and environmental sustainability.
