Don't be like them unhealthy hunter/gatherer tribes that get the majority of their calories from meat and nuts!
1365 calories a day from the Monongo nut (which the go to great effort to collect)
690 calories from meat
300 calories from plant
Approximately 60% animal and nut by weight to 40% plant..... Interesting little read.
Of course the caloric density complaint is a double edge sword. For HG's caloric density is a necessity in food choice. This may not be so for us, but I would question any presumption of these foods being unhealthy based on a reductionistic account of PUFA levels alone.
