This document provides an overview of nutritional interventions. It discusses direct and indirect interventions, as well as essential nutrition actions. Direct, nutrition-specific interventions target the immediate causes of undernutrition like inadequate dietary intake and illness. Examples include breastfeeding promotion, complementary feeding, and management of acute malnutrition. Indirect, nutrition-sensitive interventions address the underlying determinants of undernutrition through sectors like agriculture, social protection, and education. Essential nutrition actions promote seven evidence-based practices to improve nutrition, delivered through integrated health services and community programs. The document outlines considerations for planning, implementing and evaluating effective nutritional interventions.
