Matthews work focuses on developing projects for education and research around growing food for nutrition. Author of ‘Beyond Organic, a Vision of the Future’, published in the Soil Association’s journal Mother Earth, Matthew contends that food quality should be defined by its nutrient qualities which, if a standard were calibrated correctly, will lead humans towards forming a symbiotic relationship with nature because it would require healthy soil, water and air to grow better food plants, increase biodiversity of soil and gut microorganisms which would lead to better health of animals and humans.

Elizabeth has worked as a practitioner, academic researcher and consultant in non-governmental organisations and the UN on health, nutrition, food security and agriculture projects in emergency and development contexts of sub-Saharan Africa and Asia. When first coming across Brix handheld refractometers and spectroscopy in 2016, Elizabeth was immediately struck by the potential such a tool has for improving public health. She saw her passions of community-based nutrition, permaculture, food systems, food security and poverty reduction coalesce in a scanner which democratises and shares knowledge on nutrient density.
