The Future Of Bread is in your Hands

How the BALM Framework is key in supporting the future of how we make healthier bread

With diet-related chronic diseases, such as diabetes and heart disease, becoming ever more prevalent, it has never been more important to understand how to bake healthy bread. Healthy bread (as part of a balanced diet) can support gut health and prevent and manage non-communicable diseases.  A major part of the work that has been done at the Sourdough School over many years is in creating an evidence-based framework that ensures bakers, healthcare professionals, and the public can access and understand how to bake, eat and share healthy bread and how bread contributes positively to public health.

How we Further Personalise Bread

The BALM Protocol provides a clinically proven framework as a lifestyle medicine approach to support gut health, mental health, and overall well-being. This is our foundation.

However, not everyone’s nutritional needs are the same, which is where Nutrigenetics comes in. By tailoring the bread specifically to an individual’s genetic profile, Nutrigenetics personalises the approach to better suit specific needs.

While the BALM Protocol ensures that bread is prepared in the healthiest way possible, Nutrigenetics refines this further, taking into account genetic factors that affect nutrient absorption, detoxification, and metabolism. This doesn’t make one approach inherently healthier than the other, but Nutrigenetics adds a layer of precision, targeting specific conditions such as neurodiversity, IBS, IBD, cancer prevention, cardiovascular health, blood pressure, anxiety, and depression. This personalised, preventative approach allows me to adapt the bread to each individual’s unique genetic requirements, offering functional support to those facing particular health challenges.
