Collecting dietary diversity data through high-frequency phone call surveys rather than through a one-time, in-person survey produced a lower household dietary diversity score but a higher women’s dietary diversity score, suggesting that the recall period impacts overreporting and underreporting food consumption.
Well-designed emergency cash and food distribution programs, social safety nets, school food programs, integrated nutrition interventions, and universal health care can improve outcomes for those facing food insecurity and malnutrition. These programs can also improve gender equality and climate change resilience.

Delivering nutritious and safe food requires government institutions with strong food regulatory and enforcement capacity to establish evidence-based standards and enable compliance, writes USAID Chief Nutritionist Shawn Baker. The private sector needs greater capacity, commitment, and access to financing.
Research and policy agendas should focus on who and what is given space in nutrition debates, how power is exercised, knowledge of alternative and sustainable food systems, and incorporating equality issues in the design and evaluation of interventions.
