Highlights of American Aging Association (AGE) meeting
summer, 2006. AGE was founded by
Dr. Denham Harman, who initially developed the free radical theory of aging and
the importance of antioxidants to good health.
Here are notes from the three day meeting I attended.
I. KEY IDEA PRESENTED: Happiness is a better health
predictor than cholesterol level, blood pressure, or body weight.

II. Here is a list of serious health concerns you ought to
avoid:
1. obesity
2. high triglyceride level in blood
3. low HDL - the "good" cholesterol
4. High blood pressure over 130/85
5. Elevated fasting
blood glucose levels - indicator for diabetes
If you have 3 of these 5 characteristics, you have metabolic
syndrome.
III. Genetic testing is now available to determine things
like your ability to lose weight - expensive now, $1-300/panel of SNPs. But will be inexpensive in the near future. PLIN-11 SNP can predict your ability to
lose weight.
IV. Aging upregulates inflammation in adipose tissue. So if you are thin, you have less
adipose tissue, less inflammation, lower risk for cancer, heart disease,
diabetes, stroke, and Alzheimer's.
There is a 14-fold increase in diabetes from age 44 to age 65.
V. Aging is not so bad! In 1960, we thought kidney function and cardiac output
declined with age. Now we know they do not. 3 functions increase with age: creativity, wisdom, spiritual
strength. Melatonin affects gene expression levels, causing 50% of gene
expression level changes with age to revert to youthful levels.
VI. Presentation by Mark SMITH on Alzheimer targets
- oxidative stress precedes amyloid plaque by decades. amyloid appears to protect neurons and
might not be cause of alzheimers. Lipid levels change dramatically with age, so
fish oil is really important with age. Melatonin and curcumin decrease risk of Alzheimer's.
VII. Presentation by the man who made blueberries famous for
their antioxidants - Jim JOSEPH - Here are dietary interventions for healthy
brain
Vitamin C, E, alpha-lipoic acid, carnitine, melatonin, fish
oil, fruit phenolics which include flavanoids, anthocyanins, and
flavanols. Anthocyanins enter the
brain directly. Avocado and
blueberry and strawberry have powerful polyphenolics. All are anti-inflammatory, especially in the hippocampus
that is primary in memory function.
VIII. Conclusion of May 15-17, 2006 NIH conference on
multivitamins - The present evidence is insufficient to recommend for or
against multivitamins. Yet 52% of
people take them, 38% say they take them for more energy.
