Food unavailability and poor economic situations, limited exposure to nutrition counseling, food restrictions and beliefs, adverse family influence and gender norms, and gaps in knowledge constrain healthy diets. While food-based programs, behavior change communication, and nutrition-sensitive agriculture interventions are promising strategies, impact evaluations show that they face implementation bottlenecks and limited effectiveness when undertaken at-scale in the real world. Investing in systems approaches spanning health, nutrition, and agriculture sectors is critical to promote healthy diets for women.
