The hunter-gatherer tribes that today live like our prehistoric human 【M1】______
ancestors consume primarily a vegetable diet supplementing with animal foods. 【M2】______
An analysis of 58 societies of modern hunter-gatherers, including the Kung of
southern Africa, revealed that one-half emphasize gathering plant foods,
one-third concentrate on fishing, and only one-sixth are primarily hunters.
Overall, two-thirds and more of the hunter-gatherer’s calories come from 【M3】______
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 【M4】______
calories, as an hour of gathering produces 240. 【M5】______
Plant foods provide for 60 percent to 80 percent of the Kung diet, and no 【M6】______
one goes hungry when the hunt fails. Interestingly, if they escape fatal infections
or accidents, these contemporary aborigines live to old ages despite of the absence 【M7】______
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). 【M8】______
If no one is suggesting that we return to an aboriginal life style, we certainly 【M9】______
could use their eating habits as a model for healthier diet. 【M10】______ [br] 【M4】
