Food and nutrition have long been viewed as a critical issue for human health and development, but, until quite recently, the ‘food problem’ was primarily framed as one of malnutrition or hunger and the main concern was ensuring caloric sufficiency. There was, in other words, little or no mention of food in relation to obesity and chronic disease, be it in the international health agenda or the global food security literature (Reubi et al., 2016). This framing has been increasingly challenged over the past few years.
