Resumen
Descripción
In many parts of the world, people are changing their lifestyles as, moving to urban areas, they adopt new diets and more sedentary behaviour patterns. Because energy intakes exceed energy expenditures, for some people obesity is becoming more common. Obesity is associated with serious chronic diseases such as diabetes, cardiovascular disease and some forms of cancer. For poor communities and countries, the prevalence of both obesity and undernutrition within the same population can make improvi ng nutrition and health even more complex. In this issue of Food, Nutrition and Agriculture, two articles discuss the relationships between social and economic change and obesity. Preventing obesity and other nutritional problems requires mass education. A third article describes strategies that nutritionists in developing countries use for developing food-based dietary guidelines.
