Image Letterbox Series 4: Vegan or flexitarian - which diet is healthier? In the quest for sustainable healthy diets, it is common to hear recommendations to reduce the amount of animal-sourced foods consumed in high-income countries.

In this Letterbox exchange, nutrition researcher Flaminia Ortenzi and physician Dr Tushar Mehta share their perspectives on the relative health and nutritional impacts of purely vegan diets compared to those that contain low levels of animal-sourced foods. Flaminia focuses on the nutrient density of different foods, while Tushar discusses data on the health outcomes of different diets. Read

Image Explainer What is ultra-processed food? And why do people disagree about its utility as a concept? The increasing consumption of industrially processed convenience foods, soft drinks, and fast foods has been associated with a rise in non-communicable diseases, overweight and obesity. This building block explores the concept of ultra-processed food: how it has been defined, and differing views as to whether it is a useful way of thinking about food and its relation to health and wider sustainability concerns.

Image Explainer What is food loss and food waste? Around one third of the weight of food produced for human consumption is lost or wasted, and around a third of crop calories are lost to the food system during livestock production. Meanwhile, the global food system causes significant environmental impacts and around 800 million people are undernourished. This building block examines the following aspects of food loss and waste: mainstream definitions and alternative understandings, global statistics, and ‘hierarchies’ for prevention and treatment.
