NUTRITION THRU THE LIFE CYCLE – Young & Middle Adult Lay foundation for lifetime nutrition pattern in
young adulthood Nutrient requirements change very little Females need to maintain/increase intake of Vit.
C , Vit D, & calcium; & maintain intake of iron Basal metabolism decreases 2-3%/decade after
age 25 Obesity, HTN , & DM may begin to form

EVALUATING If outcomes not achieved,
Was cause of problem correctly identified? Was family included in teaching plan? Are they
supportive? Is client experiencing symptoms that cause loss of
appetite? Were outcomes unrealistic for this person? Were client’s food preferences considered? Is anything interfering with digestion or absorption
of nutrients?
