Diabetes, heart disease, obesity: excess fats, carbohydrates, calories. Who is most at risk of hunger: rural poor in developing countries. Often have electricity and no safe drinking water. Health, education and sanitation services are poor. Many have no land of their own and work seasonally: urban poor. No means to produce food; have few resources to buy it: victims of catastrophes.
