I attended a seminar with Boyd Eaton yesterday (in Lund, Sweden).
He used the word _lifestyle_ rather than _diet_ to explain the differences
in health for modern westerers contra paleolitics/hunter-gatherers.
Among other intresting things he showed how the time between first
menstruation and first child increases the breast cancer risc.
This is for h-g women 3 years (16 / 19) and modern western women
11 years (13 / 24) (I am not shure I remember the last number correct).
He used pictures to show how breast are different before and after the
first child, and that cell renewal is five times faster before, making
more mutations possible.
So breast cancer can not be blamed only on the diet.
