World Entering Era of Global Food Insecurity

World entering era of global food insecurity with malnutrition and obesity side by side within countries, says leading food expert.

The world is entering an era of global food insecurity which is already leading to the “double burden” of both obesity and malnutrition occurring side by side within countries and even within the same families, a leading food expert has warned.

It will become increasingly common to see obese parents in some developing countries raising underweight and stunted children because high-calorie food is cheaper and more readily available than the nutritious food needed for healthy growth, said Alan Dangour of the London School of Hygiene and Tropical Medicine.

“We are certainly looking at a period of increased instability in the supply of food, and also the diversity and types of food that are available are going to change,” said Dr Dangour, who is to lead a major study into global food insecurity and its impact on health.

“A result of this is called the ‘double burden’ of malnutrition,” he added. “Under-nutrition causes starvation and stunting in children, whereas obesity and over-weight in adults is another form of malnutrition, caused by eating the wrong type of food.

“The double burden exists in countries, or indeed in households, where you get a stunted child and an overweight mother. And that happens in many countries around the world as a result of the wrong diets being eaten [by adults] and the wrong diets being given to children,” he said.

“It’s not the fault of the mother, it’s the fault of the food system where the mother cannot afford to buy nutritious food such as dairy, eggs and fruit and is predominantly feeding her child a diet that is rich in calories, such as oil and cereal-based carbohydrates,” Dr Dangour said. “That diet will not be sufficient for the child to grow. It will stop the child from being hungry but it will also stop the child from growing properly,” he said.

The Wellcome Trust, Britain’s largest research charity, is this week to announce that it will fund a £420,000 pilot project, led by Dr Dangour, into the health effects of food insecurity in an age of rapid climate change and a fast-expanding human population that is expected to grow from the present level of 6.8 billion to more than 9 billion by mid-century.

The researchers will analyse the effects of environmental “stressors” – including factors such as drought, soil degradation and the decline of pollinating insects – on the food supplies of Britain, Mexico and Ethiopia. The three specimen countries were selected because their agricultural systems are very different from one another.

“We know that at the end of this century it’s going to be very difficult to grow crops in certain parts of the world because of increasing temperatures,” Dr Dangour said. “In other parts of the world there is going to be increasing productivity because warmer temperatures will mean longer growing seasons.”
