Effect of Diet and Physical Activity on Mental Health
and Cognitive Well-Being | Role of Nutrition in the Etiology of Dementia | Nutrition and Late-Life Depression | Physical Activity as a Determinant of Cognitive Status | Indirect Effects of Lifestyle Factors on Mental Health
Although the specific etiological mechanisms have not been
fully delineated, it is well recognized that mental function can
be adversely affected by poor dietary choices. As shown in Figure
28–1, the interrelationships among diet and physical activity,
mental health, and physical health are critical determinants of health
and quality of life among older adults. A problem in any one component
can lead to deterioration in other components and in overall health.
For example, as shown in Figure 28–2, excess kilocalorie
intake may lead to obesity and related physical impairments that
may in turn promote depression.
