One in twelve people worldwide is malnourished, including 160 million children under the age of five. Every year, about 15 million children die of hunger. Malnutrition doesn't just occur in poor countries; poor nutrition happens in rich countries, too, where the popularity of highly processed foods, robbed of their nutritional value, can lead to health problems. This important book sheds light on why people aren't getting the sustenance they need to live healthy lives, and how the body reacts when it is malnourished.
