Agro‐food systems are undergoing rapid innovation in the world and the system's continuum is promoted at different scales with one of the main outcomes to improve nutrition of consumers. Consumer knowledge through educational outreach is important to food and nutrition security and consumer demands guide breeding efforts. Maize is an important part of food systems. It is a staple food and together with rice and wheat, they provide 60% of the world's caloric intake. In addition to being a major contributor to global food and nutrition security, maize forms an important part of the culinary culture in many areas of Africa, the Americas, and Asia. Maize genetics are being exploited to improve human nutrition with the ultimate outcome of improving overall health. By impacting the health of maize consumers, market opportunities will be opened for maize producers with unique genotypes. Although maize is a great source of macronutrients, it is also a source of many micronutrients and phytochemicals purported to confer health benefits. The process of biofortification through traditional plant breeding has increased the protein, provitamin A carotenoid, and zinc contents of maize. The objective of this paper is to review the innovations developed and promoted to improve the nutritional profiles of maize and outcomes of the maize agro‐food system.

在农业食品系统中挖掘玉米多样性并改善其营养方面

世界范围内的农业食品系统正在经历快速创新，该系统的连续性在不同规模上得到推广，其主要成果之一是改善消费者的营养。通过教育推广获得消费者知识对于食品和营养安全很重要，消费者需求指导育种工作。玉米是粮食系统的重要组成部分。它是一种主食，与大米和小麦一起提供了全世界 60% 的热量摄入。除了是全球粮食和营养安全的主要贡献者之外，玉米还是非洲、美洲和亚洲许多地区烹饪文化的重要组成部分。正在利用玉米遗传学来改善人类营养，最终结果是改善整体健康。通过影响玉米消费者的健康，将为具有独特基因型的玉米生产者打开市场机会。虽然玉米是大量营养素的重要来源，但它也是许多据称有益健康的微量营养素和植物化学物质的来源。通过传统植物育种进行生物强化的过程增加了玉米的蛋白质、维生素 A 类胡萝卜素和锌含量。本文的目的是回顾为改善玉米的营养状况以及玉米农业食品系统的成果而开发和推广的创新。和玉米的锌含量。本文的目的是回顾为改善玉米的营养状况以及玉米农业食品系统的成果而开发和推广的创新。和玉米的锌含量。本文的目的是回顾为改善玉米的营养状况以及玉米农业食品系统的成果而开发和推广的创新。
