Understanding the connection between sourdough and Alzheimer’s disease is a core pillar of our Diploma in Nutrition and Digestibility of Bread. This archive explores the Brain-Gut-Microbiota Axis, focusing on how slow fermentation and whole grains facilitate the interplay between polyphenols and immunity.

This research is of significant personal interest to Dr. Vanessa Kimbell, whose father-in-law struggled with Alzheimer’s. Within her doctoral research and the BALM framework, her work examines how "Blue Zone" longevity can inform our fermentation methods. These studies demonstrate how practical application, such as specific ingredient choices, can support brain neuromodulation and cognitive resilience.

As highlighted by the NHS University Hospital Southampton, pioneering collaborations in lifestyle medicine are essential for tackling modern health challenges. We invite you to explore these clinical insights through our Proven Bread programme to understand how your daily bake supports long-term health.
