The Global Nutrition Report 2020 revealed that one out of nine people or 820 million people worldwide are hungry, while one in three is overweight or obese. An increasing number of countries have the “double burden” of malnutrition, obesity and other diet-related diseases such as diabetes, cardiovascular disease and cancer, the report said.
The report suggested an overhaul of the world’s food and health systems is needed to tackle malnutrition, a “threat multiplier” that is now the leading cause of ill health and deaths globally.
The report also found that most people across the world cannot access or afford healthy food, due to agricultural systems that favour calories over nutrition as well as the ubiquity and low cost of highly processed foods.
David Nabarro, special representative of the UN secretary general for food security, said the report, written before the coronavirus pandemic, had a “heightened significance” and warned: “There is a real risk that, as nations strive to control the virus, the gains they have made in reducing hunger and malnutrition will be lost.”
Last month the UN warned that the pandemic could double the number of people facing acute hunger globally.
In a foreword, Nabarro says that undernourished people may be more at risk to coronavirus, due to weakened immune systems, while obesity and diabetes were linked to worse outcomes.
A failure to put on weight persists in the world’s poorest countries, at a rate up to 10 times higher than in richer countries, the report finds, while rates of overweight and obesity are up to five times higher in richer than developing countries.
The medical costs of treating the consequences of obesity are “staggering”, the report says, at an estimated total bill of US$1.2tn a year by 2025, with the US by far the biggest spender.
The report’s conclusions echo calls by climate scientists for a transformation of food and land management, after a report by the Intergovernmental Panel on Climate Change (IPPC) last year concluded that poor land use is responsible for a quarter of greenhouse gas emissions.
Cynthia Rosenzweig, a climate expert at the NASA Goddard Institute for Space Studies, and the author of the food security chapter in the IPCC’s report on land and climate change, said: “It is really a call to action for countries and international organisations, NGOs and the whole system, to create a transformation in the food system.
“Malnutrition is a threat multiplier. I think it has been ignored that people who are malnourished are likely to have lower immune systems.”
She highlighted the inequality in food prices across the world, where the cost of an egg in Burkina Faso is 15 times more in comparison with grain and rice, compared with just twice the cost of such staples in the US.
Rosenzweig urged governments and policymakers to “seize the moment” to create equal and sustainable food and health systems in the wake of the pandemic.
Venkatesh Mannar, a special adviser on nutrition to the Tata Trusts and the Tata-Cornell Institute for Agriculture and Nutrition, said: “Poor diet and malnutrition is not a matter of personal choice. Most people are not able to do this because of inequality of food systems. They not have access to a range of healthy food. The interface between the food supply chain and consumers is inequitable.”
“The crisis has highlighted the need to look at malnutrition in all its forms seriously, and we believe it can be done in tandem with tackling the pandemic.” (Source: The Guardian)
