What is ultra-processed food? And why do people disagree about its utility as a concept?

Abstract

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.
