  I think you raise an intersting question;  evolution may only "care" about
optimal heatlth through reproduction and rearing children to their own
reproductive phase.;  on the other hand,  there  may  have been some
selective pressures for healthy "elders" insofaras they were valuable to the
band or tribe for survival benefits gained from accrued knowledge and help
with child rearing.   The optimal diet for ensuring survival to to and
through the reproductive and child rearing phase may not be the best for
promotion of longevity.  excellent question. Rick
