• 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

• REALITY: While disability does increase with age, staying healthy longer is the biggest trend in late life over the past 20 yr

• MYTH: Ponce De Leon was right, there is a fountain of youth, if we could only find it
• REALITY: Genetics, personal health choice, and illness management are the “potion” that has been found
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
If you are 45 years old and do all of these (rather than none) you will live longer.
(men- 7 years, women-11 years)
1. Sleeping 7-8 hours per night 2. Weight Control 3. Exercise 4. Limited Alcohol 5. Non-smoking 6. Eating Breakfast 7. Seldom Snacking

Have someone take 2 pictures of you standing up, from both the front and side of your body.

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

Elements for Health
1. Potassium > 4,700 mg/day 2. Sodium < 1,200 mg/day 3. Water 3.7 liters/day men 2.7 liters/day women 4. Calcium > 1,200 mg/day 5. Selenium 55 ug/day 6. Magnesium 320 mg/day-women

Dietary Reference IntakesThe National Academies Press, 2005Minaker et al
Potassium Intake > 4700 mg/day
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
Dietary Reference IntakesThe National Academies Press, 2005Minaker et al
Sodium (1,200mg/day)
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
Dietary Reference IntakesThe National Academies Press, 2005Minaker et al
Time (hrs) to excrete 50% of a sodium load vs. age: young (hatched), old (solid)

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 depending on heat and exercise levels. With sweating and exercise you can lose 1-2 liters per hour
4. Sources: % of intake drinking water 35-54beverages 49-63
food 19-25

12. Riboflavin (B2) 1.3 mg/day
13. Thiamin (B1) 1.2 mg/day

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)
Medicines for Health
1. ASA 162 mg/day
