Malnutrition in its various forms—undernutrition and micronutrient deficiencies, as well as overweight and obesity—is a problem faced by all countries.

There have been many reports about these issues—reflecting the complexity of the causes, the consequences for the public burden of disease, and the increasing concerns about sustainability—but also the potential of science and technology to bring change.
