The document discusses gaps in knowledge around the nexus between dietary diversity, agriculture, and nutrition. It notes that while dietary diversity scores are good indicators, they need further refinement. There is also a need to determine if local diets can fulfill all nutrient requirements and more information is required on alternatives before promoting them. The document also highlights limitations of dietary diversity scores and presents examples of developing food-based dietary guidelines in Kenya based on locally available foods. It raises questions around whether non-traditional, underutilized wild foods could help and identifies gaps in composition data and understanding bioavailability for such foods.
