Ancient humans did not own Cuisinarts. It is likely that paleolithic mothers pre-chewed their children's food during weaning. It is also possible that when adults lost their teeth through illness or accident, others in their family group would chew their food for them.
Should modern paleos emulate the practice of pre-chewing a child's food during weaning? Aside from the nutritional benefits, are there immune or other protective advantages? Do the risks of communicable diseases such as strep or HIV outweigh the possible benefits? Good eats or gross re-enactment?
