Nutrition and Healthy Aging.

Diet is a key determinant of health and is vital to the prevention and management of chronic disease. The predictors of an individual's dietary health are complex and influenced by multiple socioeconomic, environmental, and behavioral domains. Dietary behavior change in late life requires an in-depth understanding of internal and external factors influencing the individual and knowledge of community resources available. Dietary patterns-the combination of foods and beverages consumed-may be related to quality of life and health in older adults. Dietary patterns may also be easier for individuals to adopt and understand than dietary planning based on single nutrients.
