微量营养素缺乏影响了世界上近一半的人口，损害了儿童的发育，降低了工作效率，并通过影响传染病和慢性病而增加了死亡率和发病率。为了养活日益增长的世界，有必要在粮食系统的广泛背景下将农业视为公共健康的工具，从而在寻求可持续性的同时解决营养平衡问题。这些努力将包括增加种植系统的多样性、增加微量营养素的产出和促进环境的可持续性。这种方法的例子是必需的微量元素硒(Se)，它的高摄入量可以降低癌症风险，但在世界许多地区都是缺乏的。讨论了基于食品系统的方法，通过增加几种生物可用形式的硒的任何一种的摄入量来防止硒缺乏，并通过增加支持抗肿瘤的硒代谢物的元素的形式的摄入量来降低癌症风险。
Micronutrient deficiencies affect nearly half the world's population, impairing child development, reducing work productivity, and increasing mortality and morbidity rates by affecting both infectious and chronic diseases. To feed a growing world, it will be necessary to consider agriculture in the broad context of a food system as an instrument of public health and, thus, to address nutrient balance while also seeking sustainability. Such efforts would include increasing cropping system diversity, enhancing micronutrient outputs and promoting environmental sustainability. Example of this approach are presented for the essential trace element selenium (Se), which at high intakes can reduce cancer risks but is deficient in many parts of the world. Food systems-based approaches are discussed for preventing Se deficiency by enhancing intakes of any of several biologically available forms of Se, and for reducing cancer risk by enhancing intakes of forms of the element that support anti-tumorigenic Se-metabolites.
