Consumer preferences matter for transforming food systems for sustainable healthy diets: Evidence from rural Bangladesh

Food system transformation strategies rely on consumer demand response for achieving sustainable healthy diets, but food consumption patterns and consumer preferences are often not well understood in many countries of the global South. This brief examines consumer demand in Bangladesh, a country in the take-off stage of agrifood system transformation, that has experienced improvements in diet quality but also an increasing incidence of overweight, with faster increases in rural than urban areas. The authors estimate responses in consumer demand to changes in incomes and changes in food prices, finding that rural consumer demand is driven by strong preferences for animal-source foods, while the demand for sugar and highly processed foods increases faster than total food demand when income rises. They conclude that agricultural value chain development can be an important policy instrument for improving household diet quality but can also lead to undesirable dietary change if food consumption incentives conflict with nutritional needs.

Dairy consumption and household diet quality in East Africa: Evidence from survey-based simulation models

Dairy foods are an important source of essential macro- and micronutrients in household diets, and their consumption is associated with reduced malnutrition, especially among young children. Low dairy consumption in many developing countries is a justification for programs that promote dairy livestock ownership, help develop dairy value chains, or stimulate dairy demand. While several studies confirm the beneficial effects of such dairy-specific interventions on nutritional outcomes, the purpose in this study is to consider more broadly the contribution of dairy to overall diet quality. Our assessment of consumer preferences for dairy, coupled with simulations of consumption responses to dairy price and household income changes, provide quantitative evidence that can inform policymakers about the possible effects of public policies on dairy consumption and diet quality. While our analysis is based on data from Kenya and Uganda, both countries with established dairy sectors, our findings are relevant for other East African countries with similar dietary patterns and emergent dairy sectors.
