The hunter-gatherer tribes that today live as our prehistoric 【B1】
human ancestors consume primarily a vegetable diet supplementing 【B2】
with animal foods. 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 【B3】
more of the hunter-gatherer's calories come from 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 calories, 【B4】
as an hour of gathering produces 240. 【B5】
Plant foods provide for 60 percent to 80 percent of the Kung diet, 【B6】
and no 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 of medical care. They experience no obesity, 【B7】
and no middle-aged spread, little dental decay, no high blood pressure, no
heart disease, and their blood cholesterol level are very low (about half of 【B8】
the average American adult. ) If no one is suggesting that we return to 【B9】
an aboriginal life, we certainly could use their eating habits
as a model for healthier diet. 【B10】
