Nutrition through the
Life Cycle
Adult and Elderly
Definition of Adulthood
With good luck, good genes, and good
habits, adulthood covers a life span of
roughly 60 years.
• Early Adulthood – by the age of 20, adults
have generally stopped growing
• Midlife – forties and fifties – body composition
shifts, hormones shift, and activity decreases
• Old Age – after sixty – consequences of
earlier lifestyle choices
Physiological Changes
of Adulthood
• Growth and maturation are complete by
early adulthood
• Nutritional emphasis turns to
maintaining physical status, continuing
to build strength, and avoiding excess
weight gain
• Differences between:
• Males
• Females
Energy Needs
• MyPyramid.gov
• Harris-Benedict Equation
• Mifflin-St.Jeor Equation
Dietary Recommendations
• Governmental and private groups make food
and nutrition recommendations according to
their missions and goals
– Advocating for reduction of specific disease risk
(i.e. American Heart Association)
– Ensuring adequate population intake specific
nutrients (i.e. FDA – fortification of grain products)
– Offering guidance on what and how much to eat.
(i.e. Food Guide Pyramid, Dietary Guidelines for
Americans)

• 85 and older is “oldest old”
Diseases and disabilities are not
inevitable consequences of ageing
Longevity
• The Center for Disease Control and
Prevention suggest that longevity
depends on:
– 19% genetics
– 10% access to health care
– 20% environmental factors
– 51% lifestyle factors
