In this issue of Public Health Nutrition, we feature an Editorial by Mark Lawrence and colleagues responding to the 2019 report ‘Food in the Anthropocene: the EAT–Lancet Commission on healthy diets from sustainable food systems’ (Lancet 393, 447–492). In keeping with this topic, this issue includes two papers specifically looking at diet health and sustainability from very different perspectives:

• ‘A healthy, sustainable and safe food system: examining the perceptions and role of the Australian policy actor using a Delphi survey’ by Sinead Boylan and colleagues;

• ‘Are our diets getting healthier and more sustainable? Insights from the European Prospective Investigation into Cancer and Nutrition – Netherlands (EPIC-NL) cohort’ by Sander Biesbroek and colleagues;

a paper looking at an agroecosystem approach to dealing with food security and health in Bangladesh:

• ‘Linking agroecosystems producing farmed seafood with food security and health status to better address the nutritional challenges in Bangladesh’ by Baukje de Roos and colleagues;

two studies of the use of traditional foods and their potential to contribute to healthy and sustainable diets:

• ‘Mothers’ beliefs about indigenous and traditional food affordability, availability and taste are significant predictors of indigenous and traditional food consumption among mothers and young children in rural Kenya’ by Constance Gewa and colleagues;

• ‘Local traditional foods contribute to dietary diversity and species richness of rural women in Ecuador’ by Dolores Penafiel and colleagues;

and a paper on potential problems when food production systems are not safe and healthy:

• ‘Production-related contaminants (pesticides, antibiotics and hormones) in organic and conventionally produced milk samples sold in the USA’ by Jean Welsh and colleagues.
