What is a sustainable diet?

This new discussion paper from Tara Garnett of the Food Climate Research Network “What is a sustainable healthy diet?” is essential reading for all of us interested in sustainable food. It’s already creating quite a storm on twitter. You can  read about it and download it here. Her final sentence reads “The task … is to shrink our consumption patterns to fit the “safe operating space‟ available for humanity (Rockström et al, 2009).136    This points to the need for fairly drastic changes, and in particular to a reduced consumption of animal products. As to the nutritional implications, since their focus is generally on issues of excess they focus on problematic macro-nutrients (energy, fat) rather than on the micronutrients (iron, zinc, calcium) associated with insufficiency. From this perspective lower meat diets are seen as actively beneficial to health: win wins are possible.”
