The challenges to achieving sustainability in food and nutrition are daunting. The present paper summarizes 3 individual papers that are part of this special collection. The lynchpin for synthesizing the papers is sustainability and food systems. Within each of these domains are embedded a myriad of factors, each of which are essential for the sustainable transformation of food systems. Controversies surrounding the concepts of a healthy diet, sustainable agricultural production, and maximizing the dietary impacts of food environments are discussed and evaluated in the context of the current food and nutrition landscape.
