The word 'malnutrition' makes most people think of a thin child, starving because of famine. Aid agencies have helped to reduce the number of people who do not have enough food to eat in developing countries. But the starchy foods which are available to them at low cost – plus the emergence of cheap junk food – is fuelling another form of malnutrition - obesity.
