the same can be said about those peoples living in the northern part of the world for countless hundreds of generations, never eating bananas or durian, and those living near the equator. They didn't have any chance of adapting to bananas... Any yet we don't say that if we have northern European blood lines, 'Don't eat a banana!' It's so easy to mentally try to figure things out.
Oh that's right, I forgot, before they migrated to the northern regions, they had had their fill of bananas before they left. Hmm, I wonder if that's why they left, the 30 banana a day diet eventually didn't satisfy.
Lol yeah perhaps
I guess your right, however bananas are not constituted the same way as milk, which is a food rich in specific hormones and nutrients exclusively aimed to the nutrition and development of the little one of a particular specie. And bananas are much more easily available for human consumption than the milk of another animal, in times prior to the Neolithic era (agriculture), if those ancient humans would happen to end up in an area where bananas grow.
Humans also had access to fruits native to America such as tomatoes or deep sea fishes very late in their evolutionary course, but I think humans can do better on these kind of food because they "behave" in a similar way to other foods (fruits, vegetables, meat) with one's organism as opposed to milk, which is a food specifically produced-for and directed to one particular specie's younglings, and to them only.
Apparently Japanese kids who where introduced to dairy, a center piece of the Occidental diet, noticeably grew in size as compared to their parents, but demonstrated issues in brain development and intelligence. In fact the milk calves feed on is meant for them to develop important bone mass, and little brain. While it is almost the opposite with human milk (lots of brain, less bone mass).
But this subject has been discussed countless times, and as it has more or less been agreed by the members of this forum that milk is not a common"Paleo" food. I guess it only comes to the individual to experiment for himself, and take responsibility for doing so when the person decides to eat such food on a regular basis.
