Prevention of premature chronic diseases is an important component of healthy aging. Nutrition education can help to reduce the risk of premature chronic diseases in some older adults. Home delivered meals and congregate dining services assist vulnerable elderly persons by providing opportunities for nutritional and social support. Screening and assessment tools identify factors affecting nutritional health and can also provide specific directions for planning, implementation, and evaluation of tailored interventions. Dietitians and allied health professionals are well positioned to assist a heterogeneous population of older adults in securing nutritional adequacy.
