Growing Real Food For Nutrition CIC

Exploring how to grow, measure and promote the benefits of nutrient dense food

Our vision is for a world where all food is grown for its nutritional qualities using regenerative practices. Nutritious food will be made accessible to all, creating an abundance of health and harmony, reconnecting humans with Mother Earth.

Growing Community

We want to create a community of growers, chefs, nutritionists and food citizens; everyone who is a steward of our food future.

Growing Knowledge

With simple equipment you can learn to test the quality of food to indicate its nutrient density and verify results with comparative taste testing.

Growing Awareness

Let nature do the talking!  Grffn offer workshops to increase your experiential relationship with nature. Workshops explore food quality issues, teach how to test and record food quality values (Brix) and conduct comparative taste testing sessions to verify results. Results can be uploaded to Grffn's Citizen Science database to help build evidence for a regenerative future.  

Join Us


Grffn are developing citizen science projects to help understand how well a plant has been grown i.e. food quality. This aims to empower trust in the human senses, so we can understand and self-select well grown, nourishing, nutrient dense food. Both growers and food citizens are invited to get involved.  


Record your Brix values in our database to establish a baseline and compare results with others. Learn and share best practise to increase quality year on year.

The Bionutrient Meter

Grffn supports the development of the Bionutrient Meter which aims to measure the nutrient density of fruits and vegetables, in real time. 

Grffn’s ‘Food Quality First’ pilot project 2022/23 partnered with the Bionutrient Institute (USA) to share their methodology for a UK pilot project. Fascinating results highlight the complexity of attempting to define Food Quality by its nutrient density.
