Samples of the plasma from nine male adult bushmen were analyzed for their lipid content. The mean results obtained (total cholesterol = 77 mg/100 ml, phospholipids = 107 mg/100 ml, and triglycerides= 49 mg/100 ml) were extremely low. The probable reasons for this finding are the very low dietary fat content and habitually high physical activity of Kalahari bushmen.
