Suboptimal diets are the most important preventable risk factor for the global burden of non-communicable diseases. The EAT- reference diet was therefore developed as a benchmark for gauging divergence from healthy eating standards. However, no previous research has comprehensively explored how and why this divergence exists in poorer countries undergoing nutrition transitions. This study therefore analyzes dietary patterns and drivers of the demand for nutritious foods using nationally representative household surveys from Ethiopia, Kenya, Tanzania, and Uganda. We show how barriers to dietary convergence stem from combinations of poverty, high relative food prices and weak preferences for some specific healthy foods. The article concludes by discussing interventions for strengthening consumer demand for healthy diets in Africa.
不良饮食是全球非传染性疾病负担最重要的可预防风险因素。因此，制定了EAT参考饮食作为衡量偏离健康饮食标准程度的基准。然而，以前没有研究全面探讨过在经历营养转型的较贫穷国家，这种偏离是如何以及为何存在的。因此，本研究利用来自埃塞俄比亚、肯尼亚、坦桑尼亚和乌干达具有全国代表性的家庭调查，分析了饮食模式和对营养食品需求的驱动因素。我们展示了饮食趋同的障碍是如何源于贫困、相对较高的食品价格以及对某些特定健康食品的偏好薄弱等因素的综合作用。本文最后讨论了加强非洲消费者对健康饮食需求的干预措施。
