The 2020 edition of the Global Nutrition Report uses the concept of nutrition equity to examine multiple forms of malnutrition, including undernutrition and obesity. The report stresses that poor diets and malnutrition are not simply the result of personal choices - rather, the problem is systemic, with the vast majority of people being unable to access or afford a healthy diet. It calls for coordinated action between stakeholders to build equitable, resilient and sustainable food and health systems.

This paper explores the association between consumption of ultra-processed foods and indicators of obesity in a sample of the UK adult population, using data from the National Diet and Nutrition Survey between 2008 and 2016. 

This report outlines the 2019 activities of the Centre for Food Policy at City, University of London. 

This report from Sustainable Diets for All (a programme by Hivos and the International Institute for Environment and Development) documents a food diaries project in East Java that aimed to address the triple burden of malnutrition: co-existing undernutrition, overweight and micronutrient deficiencies.

This book shows how stories about the food system can be framed in different ways, and how people are affected by how stories are told about them. The book focuses on food insecurity, farm labour and obesity.

This report from the UK Soil Association’s Food for Life initiative explores the state of children’s food in England. It finds that 4 in 10 children leaving primary school will be overweight or obese by 2024, nine out of ten preschool children eat too much sugar and UK families eat the most ultra-processed diet in Europe.

This review paper argues that obesity and mortality in the United States could be reduced by limiting consumption of sugar-sweetened drinks and processed foods and meats, because of the tendency of processed foods to encourage people to eat more food (based on trials in people), and the inflammatory effect of emulsifiers such as carboxymethylcellulose and polysorbate-80 (based on mouse and in vitro studies, not studies in people).

The Lancet and the World Health Organisation have produced a series on the double burden of malnutrition and how it affects low- and middle-income countries. The double burden of malnutrition refers to the simultaneous presence of overnutrition (e.g. overweight and obesity) and undernutrition (e.g. stunting and wasting) in a country, city, community or person. 

Children in New York City who live less than 0.025 miles (about half a city block) from a fast-food outlet are more likely to be obese or overweight than children who live further away, according to this paper. The probability of a child being overweight was up to 4.4% lower and the probability of obesity was up to 2.9% lower for children who lived further away, relative to those who lived closest to fast-food outlets. The study used over 3.5 million data points (measurements of body mass index) from the New York City public school system between 2009 and 2013.
