This food diversity is MASSIVE. Diets very from high carb to low carb depending upon what is available in the given location of the paleolithic peoples.
And before anyone says it, yes there is a epidemic of disease, but im not talking about a diet of frankenfoods and seed oils but real foods, high in calories, fats, carbs and protein. Everyone here knows what im saying even if they want to scream bullshit and point to a SAD. (I hate that term, it implys that anyone not on a certain diet is eating horribly and has multiple diseases.)
I do consume it out of pleasure as part of living in the modern world and because it is a joy. I consider it a pleasure, but not a regular part of my diet. Similarly, paleo man would go to great lengths to get honey -- which was considered a sweet treat, an occasional joy (and people died getting it in the old fashioned way. I've watched some documentaries of traditional honey gathering. Truly fascinating!).
I guess what im saying is that just because something isnt paleo or doesnt jive with how a person from that era would do things does not automatically mean it is unhealthy in the short or even long term (example, eating high amounts of sugar.). Context always matters.
Loosing one's teeth is a big problem, and while we might say that we have methods of managing it in our modern world (brushing teeth, etc), the reality is that the low-sugar diets lead to much healthier teeth.
Here, it's quite common for families to have a lot of sugar in their diets -- children receiving a lot of it. That being said, people also do a lot of very healthy foods because things are grown here really nicely (a lot are organic but not certified due to the expense/difficulty, pasture raised eggs/meats/dairy, etc. . .).
My son, who gets very little sugar compared to other children, eating paleo and such, has far better teeth than most of his counterparts. Our dentist said that he was truly amazed at how healthy DS's teeth are at his age, as he is used to seeing other children his age with terrible teeth. While we know that genetics can play a part in this, the dentist asserted that it is the amount of sugar that most people eat these days -- even just unknowingly -- that is affecting their dental/oral health.
My son has had zero cavities, but I know many children his age who have already had teeth removed and/or filled due to tooth decay. These are children who eat *mostly* healthy nutritious foods but do have sugar every day (white sugar/brown sugar).
My son doesn't, and I think it makes a difference.
