I would say that any of this is affirming the consequent and poor reasoning. If X lifestyle is optimal then Y population will do well on it. Y population does well on it, therefore X lifestyle is optimal. It is fallacious reasoning because there is no way to know if there is indeed a better way that doesn't appear in populations (most of the world is either poor or rich and eats junk food), and there is no way to know what is the cause of the success, it is shooting blindly in the dark. Also we can't isolate confounding factors and are only making blind generalizations.
Negative stress and emotions are bad, enjoying daily activities is good, sleep is good, exercise is good but chronic cardio is bad. I agree and there is actual evidence to back this up instead of baseless assumptions. But with the food thing we are going to have to use our brains better. It may just be that if there is good infrastructure and health care, so long as people avoid sugar, processed junk, tons of omega 6 and get good nutrition then they can also expect to live 100+ years and so what these people are observing is not the virtues of beans and the evils of meat, but the difference between industrial diets and non industrial diets with many confounding factors. But keeping in mind that there is tons of evidence support paleo/primal to be optimal, and there are no examples of paleo/primal populations that also have a good quality of life and standard of living in the world, we can't use any epidemiological observations to decide what we ought to eat since there is no context to be found, except that hunter-gatherers tend to be very metabolically healthy, they just get killed by non degenerative factors. Anything to relish in pretense and avoid critical thought. Forget this guy, beans suck and a hefty chunk of ruminant fat coupled with fish fat does the body good.
There may be some truth that too much protein can shorten lifespans but that is generally over the 20% mark, hence high fat, moderate protein, low/moderate carbs, no poisons, good nutrition and lifestyle. A certain amount of protein will be more of a boon than not.
