GOLDFINCH is a study on ultra processed foods (UPFs) that is being led by researchers at Imperial College. We are currently recruiting members of the public to the project’s Public Reference Group (PRG). The PRG will help researchers to understand the issues that matter to communities most affected by unhealthy diets. We are looking for members of the public over the age of 18 with an interest in healthy eating and/or food environments who understand the difficulties of choosing healthier foods.
