Ready-to-use therapeutic food for prevention of childhood undernutrition.

Undernutrition is a major contributor to child mortality and total global disease burden. Ready-to-use therapeutic food (RUTF) is recommended by the World Health Organization for community-based management of uncomplicated forms of severe acute malnutrition. New research has evaluated the role of RUTF for the prevention of childhood undernutrition. While studies have found some benefit, similar results have been seen with supplemental food aid and controversy over the role for RUTF in prevention efforts continues. For the prevention of childhood malnutrition, the following questions remain critical: Who should receive a specific nutrition intervention? What composition and form should the intervention take? And, when should the intervention be delivered?
