Life Cycle Nutrition
Adult
Seniors
Adult 18 -64
Womens issues
More prevalent in females are
osteoporosis -80 % of cases
autoimmune cases- 75 % of cases
disproportionate number of cases of
-diabetes mellitus
-irritable bowel syndrome
-psychiatric conditions (e.g.
depression)
Adult 18 -64
Womens issues
heart disease # 1 killer-estrogen delays onset of
heart disease but post-menopausally when estrogen
drops then females catch up in a hurry to men in
terms of numbers of those with clinically significant
heart disease
-diet low in fat and saturated fat, rich in fruits and
vegetables (7-8 servings daily) and whole grains
and not excessive in whole calories combats heart
disease in females
Adult 18 -64
Womens issues
cancer- # 2 killer (lung, breast, then colorectal)
-dietary reduction of cancer risk:
-eat 7-8 servings of fruits and
vegetables daily
-phytoestrogens in soy believed
to help though isoflavones
in one animal study increased
cancer rate
obesity- apparently greater in females leading to
greater risk of type 2 diabetes
Adult
Men’s issues
Shorter lifespan than females due to
higher degree of risk taking- nutrition
can do nothing about this fact
At all ages 88 % more likely to die from
heart disease
45 % more likely to die from cancer
18 % more likely to die from stroke
69 % more likely to die from pneumonia
or influenza
Adult
Men’s issues continued
However heart disease and cancer are
number 1 and 2 killers of all adults
Heart disease
-risk factors same as women
Adult
Men’s issues continued
Cancer
-cancers of lower esophagus and lower stomach
are rising and both are higher in men than in
women
-lower esophageal cancer apparently related to
obesity and inadequate intake of fruits and
vegetables
Seniors (65 and older)
-80 % of seniors have at least one of arthritis,
hypertension, heart disease or diabetes
-loss of lean body mass and increase in adipose
tissue leading to progressive decrease in basal
metabolic rate
-loss of teeth, periodontal disease and decrease in
jaw bone mass (osteoporosis), in some there is
decreased saliva (may be medication related)
Seniors (65 and older)
-increased constipation due to:
decreased peristalsis secondary to:
a)
lost abdominal muscle tone,
b) inadequate fluid and fibre intake,
c) drug therapy,
d) decrease in exercise
Seniors (65 and older)
Central nervous system difficulties experienced
include- dementia, tremors, slowed reaction time,
personality changes and depression- consequences?
Bladder issue-incontinence
