Climate change, rapid urbanization, war, and economic recession are key drivers of the current food systems' disruption, which has been exacerbated by the COVID pandemic. Local, regional, and global food systems are unable to provide consumers with nutritious and affordable diets. Suboptimal diets exacerbate the triple burden of malnutrition, with micronutrient deficiencies affecting more than two billion people, two billion people suffering from overweight, and more than 140 million children who are stunted. The unaffordability of nutritious diets represents an obstacle for many, especially in low- and middle-income countries where healthy diets are five times more expensive than starchy staple diets. Food system transformations are urgently required to provide consumers with more affordable and nutritious diets that are capable of meeting social and environmental challenges. In this review, we underline the critical role of innovation within the food system transformation discourse. We aim to define principles for implementing evidence-based and long-term food system innovations that are economically, socially, and environmentally sustainable and, above all, aimed at improving diets and public health. We begin by defining and describing the role of innovation in the transformation of food systems and uncover the major barriers to implementing these innovations. Lastly, we explore case studies that demonstrate successful innovations for healthier diets.
气候变化、快速城市化、战争和经济衰退是当前食品系统中断的主要驱动因素，而 COVID-19 大流行又使这一情况进一步恶化。地方、区域和全球食品系统无法为消费者提供营养和负担得起的饮食。膳食质量不佳加剧了营养不足的三重负担，超过 20 亿人缺乏微量营养素，20 亿人超重，超过 1.4 亿儿童发育迟缓。对于许多人来说，营养饮食的负担难以承受，尤其是在中低收入国家，健康饮食比淀粉主食饮食贵五倍。迫切需要进行食品系统转型，为消费者提供负担得起的、更有营养的饮食，以应对社会和环境挑战。在这篇综述中，我们强调了食品系统转型话语中创新的关键作用。我们旨在确定实施基于证据和长期的食品系统创新的原则，这些创新在经济、社会和环境方面是可持续的，最重要的是，旨在改善饮食和公共健康。我们首先定义和描述了创新在食品系统转型中的作用，并揭示了实施这些创新的主要障碍。最后，我们探讨了一些案例研究，这些研究展示了更健康饮食的成功创新。
