Malnutrition occurs when people don't have enough to eat, or their body is unable to absorb nutrients because of an illness.
Acute malnutrition weakens the immune system, making it less able to fight infections.
In cases of severe acute malnutrition, swelling of the abdomen, face and legs, and changes in skin pigmentation may occur.
Médecins Sans Frontières / Doctors Without Borders (MSF) uses ready-to-use therapeutic foods to treat malnutrition. These are prepackaged foods that contain all the nutrients that the body needs and that require no preparation. One of the most common is Plumpy'Nut, which is based on peanuts.
