Malted barley
Produced by allowing barley grains to germinate, then dried quickly before a plant develops.
Internationally recognised as a leading authority on bread nutrition and digestibility, Dr Vanessa Kimbell holds a doctorate in Baking as Lifestyle Medicine and preventative healthcare.
Have you ever wondered why some breads make you feel tired, foggy and achy — or been puzzled that some leave you bloated while others don’t? If you can eat sourdough but not other bread, these articles and recipes are a great place to spark curiosity: learn how bread interacts with the gut microbiome, discover how your unique nutrigenetics shape your response, and read practical, evidence-based guidance. Cutting through the nonsense with clear, useful explanations, Vanessa shares tips, information, advice, recipes and methods to bake, eat and share healthy bread to support digestion and overall health. You can read more about training in personalising bread 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
