回顾了队列和横断面数据，以描述饮食摄入量随年龄的变化。总能量摄入量随年龄的变化而变化很大，男性减少1000至1200千卡，女性减少600至800千卡。这导致了大多数营养素摄入量的相应下降。对于一些营养素，相当多的美国老年人只摄入了推荐膳食摄入量的五分之一到三分之一。对于大多数营养素来说，尽管有一些证据表明与年龄相关的吸收和代谢功能下降，但缺乏判断随年龄减少的营养素摄入量对健康影响的研究。随着人口老龄化，需要对营养需求和健康结果进行更多研究，需要公共卫生努力增加老年人的体力活动和食物摄入量。
Cohort and cross-sectional data were reviewed to describe the changes in dietary intake with age. Total energy intake decreases varied substantially with age, by 1000 to 1200 kcal in men and by 600 to 800 kcal in women. This resulted in concomitant declines in most nutrient intakes. For some nutrients, substantial numbers of older Americans consumed only one fifth to one third of the recommended dietary allowance. For most nutrients, research is lacking with which to judge the health impact of reduced nutrient consumption with age, although there is some evidence of an age-related decline in absorptive and metabolic function. With the aging of the population, more research is needed on nutrient requirements and health outcomes, and public health efforts are needed to increase physical activity and food intake among older people.
