Ready-to-use therapeutic food (RUTF)

RUTF is an energy-dense, mineral- and vitamin-enriched food that requires no preparation and is specifically designed to treat severe acute malnutrition (SAM). RUTF has a similar nutrient composition to F-100 therapeutic milk, which is used to treat SAM in hospital settings. RUTF is soft and can be consumed easily by children from the age of 6 months. Because RUTF is not water-based, bacteria cannot grow in it and it can be used safely at home without refrigeration and in areas where hygiene conditions are not optimal.
