Adulthood and the Later Years
Life Cycle Nutrition• Life expectancy
– Women• African American: 76• Caucation: 81

Aging Of The U.S. Population
Observation of Older Adults
• Quality of life: How do you feel?
• Healthy habits– Physiological age– Chronological age
Very different...
“It’s not the years, honey,

Manipulation Of Diet• Energy restriction in humans: low
fat??• Would it work?
– Eat less? Less than what? Less than what you want, or less than average of population?
– Starvation....bad.– Do you eat less, or move more?– Do you have to lose weight?
– 10% less seems to be a good starting point!
The Aging Process
• Stress:• How does your body respond?
– Increased heartrate, adrenaline, sweating...– Over time this compromises your immune system,
health, etc.
The Aging Process• Physiological changes
– Body weight– Body composition: increase in
fat, decrease in muscle.•Sarcopenia-loss of skeletal muscle as we age.
The Aging Process• Physiological changes
– Immune system...again we see age compromises it. Flu shot anyone?
– GI tract-inflammation common.• Dysphagia-difficulty
swallowing...congestive heart failure?
• Tooth loss: – Oops!!– Yeah..its funny when it happends to a
dragon!– Sensory loss: sight, taste, hearing...
The Aging Process• Other changes
– Psychological changes– Economic changes– Social changes

– Vitamin D-often low due to lack of dairy intake– Calcium-if not dairy, then juices!– Iron
Energy And Nutrient Needs of Older Adults
• Nutrient supplements
