is true for those that David talked to, it is extremely interesting.

There are also other factors of potential benefit: Prehistoric
hunter-gatherers spent more time in the sun (which increases production
of vitamin D) and they had low intakes of phytic acid (which inhibits
calcium absorption) and salt (which increases urinary losses of
calcium).
