“ The hunter-gatherer tribes that today live as our prehistoric human __1__

An analysis of 58 societies of modern hunter-gatherers, including the Kung of

Overall, two-thirds and more of the hunter-gatherer’s calories come from __3__plants. Detailed studies of the Kung by the food scientists at the University
of London, showed that gathering is a more productive source of food than is hunting. An hour of hunting yields in average about 100 edible __4__calories, as an hour of gathering produces 240. __5__
Plant foods provide for 60 percent to 80 percent of the Kung diet, and no __6__one goes hungry when the hunt fails. Interestingly, if they escape fatal infectionsor accidents, these contemporary aborigines live to old ages despite of the absence __7__of medical care. They experience no obesity, no middle-aged spread, little dental decay, no high blood pressure, no heart disease, and their blood cholesterol levels are very low (about half of the average American adult). __8__If no one is suggesting that we return to an aboriginal life style, we certainly __9__could use their eating habits as a model for healthier diet. __10__
