the positive effects while reducing the negative ones to the greatest extent possible. Especially interventions that combine demand- and supply-side strategies, like economic incentives combined with educational or information campaigns, were shown to be effective in terms of changing people’s purchase and consumption behavior towards healthier foods. However, the evidence on effects of food environment interventions in African countries is very scarce. More research and political commitment will be needed to better understand food environments and their effects on diets, nutrition, and health, and to shape the demand, supply, and environmental aspects in order to increase the consumption of healthy foods among adults and children.
