Abstract：
Proper nutrition and healthy eating are key determinants of healthy aging. In older age, energy requirements decrease, yet micronutrient requirements stay the same or increase, which make older adults susceptible to nutrient deficiencies. Therefore, it is important to encourage older adults to consume nutrient-dense foods. Many older adults do not maintain proper hydration, so adequate water intake should also be encouraged. Most older adults have multiple chronic diseases that may influence their dietary intake and nutritional needs. However, currently, our understanding of how individual chronic diseases and their associated treatments influence dietary requirements is limited.
摘要：
适当的营养和健康的饮食是健康衰老的关键决定因素。在老年,能源需求下降，然而，微量营养素需求保持不变或增加，这使得老年人容易营养不良。因此,鼓励老年人食用营养丰富的食物很重要。许多老年人不保持适当的水分，因此，也应鼓励充足的水摄入量。大多数老年人患有多种慢性疾病，可能会影响他们的饮食摄入和营养需求。然而,目前,我们对个体慢性疾病及其相关治疗如何影响饮食需求的理解是有限的.
