CNN story: Can you Diet your Way to a Longer Life?

http://www.cnn.com/2003/HEALTH/11/07...ing/index.html

I have been following the research on calorie restriction and aging since
learning about Dr. Roy Walford's pioneering research while watching the
episode of Scientific American Frontiers entitled, "Fat and Happy?" (See
Dr. Walford's Web site,
http://www.walford.com , for more information). The body of evidence from
studies on laboratory animals is compelling and growing all the time:
animals which are fed a highly nutritious diet which is lower in calories
than their "normal" diet live longer--sometimes a lot longer--and are
healthier as well.
