The NACS User’s Guide is a series of modules that provide program managers and implementers with a package of essential information and resources on the nutrition assessment, counseling, and support approach. These modules are living documents and will be updated as appropriate when new evidence, guidelines, or field experience emerges. Module 3 offers an overview of nutrition education as well as information and tips on providing effective nutrition counseling and developing nutrition care plans. The module covers topics including nutrition during pregnancy and illness; infant and young child feeding; and water, sanitation, and hygiene.
