Sustainability is a central theme in my academic research. This is a vague word that can be used (and misused) because of its flexibility. Pamela Mason and Tim Lang recently addressed the concept in their book 'Sustainable Diets' (2017), and took it beyond the typical "social, environmental, economic" pieces, and added elements of social justice, governance, and (GASP!) taste, satisfaction and cultural ties - not such wild ideas when it comes to food, right?!
