The Bottom Line
• Aging as a process:
– Starts after growth/development
• Aging impacting function:
– Starts after age 80
• Aging is here to stay:
– Aging helps prevent cancer developing
• Aging can be modulated:
– You can choose your path

• MYTH: Old Age starts at 65
• REALITY: While aging
processes begin ~ age 30,
limitation of function from aging
(rather than disease) starts ~
age 80
• MYTH: The older you get,
the sicker you get
• MYTH: The older you get, the
sicker you get
• REALITY: While disability does
increase with age, staying
healthy longer is the biggest
trend in late life over the past

Three Ways to Evaluate Positive
Lifestyle Choices:
1. Direct evaluation of choices:
– Anecdote
– Groups
– Communities
2. Incorporation of choices into daily life:
– Lifestyle Programs
3. Scientific review and guideline
development
– Institute of Medicine of the National Academies
Lifestyle Choices for Health
If you are 45 years old and do all of these
(rather than none) you will live longer.

Press gently. Keep it there for a few seconds,
then gently remove tape and evaluate the skins

Look at the number 364-2872 for a 5 second count. Now
look away and cover this spot. In 5 seconds write the

the box that most closely fits
No mistakes
Do you have a positive outlook on life?

Have someone take 2 pictures of you standing up, from both Everything aligned
the front and side of your body. Draw a straight line on the
photo (if you have a digital camera, you can do this on your
computer, or just draw it on the photo with a ruler). In the
frontal photo, it should be straight from your nose through
the center of your body. In the side view, the line should be
straight from the hole in your ear to the tip of your shoulder
to your hip to your inner foot

1. The main intracellular cation affects
nerve, muscle and vascular tone
2. Good food sources include fruits,
vegetables, leafy greens, vine fruits and
root vegetables
3. Currently Americans consume much
less potassium than these guidelines
4. Decreased potassium intake is
associated with high blood pressure,
kidney stones and thin bones
Sodium (1,200mg/day)
Dietary Reference
Intakes

1. Combined with chloride and known as
salt
2. Salt maintains body fluid volume and
particulate concentration for all
metabolism
3. Current intake greatly exceeds the need
4. Most salt is added to food during
processing
5. Excess causes high blood pressure and
swelling

Water Intake per day
Men- 3.7 liters Women 2.7 liters
1. Water is the solvent for all biochemical
reactions and comprises 60% of your
body weight
2. Water absorbs heat, maintains vascular
volume, and provides a way for materials
to move in and out of your body
3. Water requirements can vary widely

Vitamins for Health- New Insights
• Vitamin D helps bone, muscle and anticancer systems
in our body
– The current hint is for high normal levels
• Antioxidants are good but how much is far from clear:
– Risk of high doses:
•
•
•
•
Vitamin A- association with lung cancer
Vitamin C- association with CAD
Vitamin E- association with heart failure
Folate, B12, B6- association with stroke, heart attack
• If you eat a good diet (> 1200 cal/day) aside from
Vitamin D you are likely getting the basic
requirements.
• In general a single multivitamin per day seems
reasonable (70% of Boston Seniors are taking them)
