Cholesterol metabolism has been studied in a group of healthy males drawn from a New Guinea highland population whose plasma cholesterol concentration is low by Western standards and does not rise with age. Mean values from compartmental studies in six subjects were: pool A mass 289 mg/kg; production rate 1069 mg/day or 17.4 mg kg-1 day-1. ⋯ In the latter group, mean cholesterol absorption was 39% (390 mg/day) but the plasma cholesterol concentration did not rise, possibly reflecting compensatory redution in synthesis. It is suggested that these results were unexceptional, except possibly for the failure of the plasma cholesterol concentration to rise when cholesterol was ingested, despite gross differences in diet and many other factors.
