Health Concerns of Older Adults
• Cancer
• Heart disease
• Hypertension
• Diabetes
• Osteoporosis
• Macular degeneration/vision problems
• Arthritis
• Alzheimer’s disease
Common Nutrition-Related
Diseases in Older Adults
Vision Problems
• Cataracts—thickening of eye lens
• Macular degeneration—deterioration of the center
of the retina, which is responsible for straightahead vision
• Antioxidants in foods may protect against vision
loss
Common Nutrition-Related
Diseases in Older Adults (cont’d)
Arthritis
• Osteoarthritis—cushioning cartilage in joint
breaks down
• Rheumatoid arthritis—disease of the immune
system with painful inflammation of the joints
• Overweight can affect arthritis
Common Nutrition-Related
Diseases in Older Adults (cont’d)
Alzheimer’s Disease
• A healthy diet can help promote brain health
• Research on a connection between diet and
Alzheimer’s disease is ongoing
Common Nutrition-Related
Diseases in Older Adults (cont’d)
Osteoporosis
• Loss of bone density, resulting in fractures
• More common in women than men
• Diet and exercise can help treat osteoporosis, but
may not prevent it in older adults
Calcium Sources
• Bok choy
• Broccoli
• Calcium-fortified juices and cereals
• Canned fish with bones
• Cottage cheese
• Fortified soy beverage
• Kale
• Milk
• Yogurt
Promoting Bone Formation
(all ages)
• Participate in weight-bearing activities
• Avoid smoking
• Consume calcium-rich foods or supplements
• Consume adequate vitamin D
