Diet and nutrition of hunter-gatherers.

The diets and nutrition of hunter-gatherers are discussed with the !Kung Bushmen (San) of the Dobe area, Botswana as the example. In general they show no qualitative deficiency of specific nutrients though they are thin and may be undernourished (by our standards) at some seasons. They show little or no obesity, dental caries, high blood pressure or coronary heart disease; their blood lipid concentrations are very low; and they can live to a good old age if they survive infections or accidents.
