FAO/18640/G. Bizzarri


Undernourishment is estimated from existing data about numbers of people and the amount of food available to them. Undernutrition is determined from data about people's weight, height and age. Ratios calculated from these measurements indicate the outcome not only of inadequate food intake but also of poor health and sanitation conditions that may prevent people from deriving full nutritional benefit from what they eat.
