The world faces a global challenge of how to meet the nutritional needs of a diverse global population through diets. This paper defines the relative nutritional needs across each stage of the life cycle to support human health and identifies who is nutritionally vulnerable. Findings in this paper suggest that there are biological nutritional vulnerabilities stemming from high micronutrient needs per calorie in certain phases of the life cycle, particularly for infants and young children, women of reproductive age, pregnant and lactating women, and older adults, particularly older women. The paper demonstrates the role of micronutrient-dense animal-source foods and plant-source foods important in meeting essential nutrient needs to support healthy growth, development, and aging across vulnerable stages of the life cycle.
世界面临着一项全球性挑战，即如何通过饮食满足全球多样化人口的营养需求。本文界定了生命周期各阶段的相对营养需求，以支持人类健康，并确定了哪些人群在营养方面较为脆弱。本文的研究结果表明，在生命周期的某些阶段，由于每卡路里的微量营养素需求量较高，会出现生物性营养脆弱性，特别是对于婴幼儿、育龄妇女、孕妇和哺乳期妇女以及老年人，尤其是老年女性。本文展示了富含微量营养素的动物源食物和植物源食物在满足基本营养需求方面的作用，这些需求对于支持生命周期中各个脆弱阶段的健康生长、发育和衰老至关重要。
