Tuesday, April 27, 2004Doctors in the United States carried out tests on 517 healthy people over the course of a year. They found that their cholesterol levels changed throughout the year, peaking in winter. They were at their lowest in summer. ...All of those who took part in the study were closely monitored by doctors to see if they changed their diet or lifestyle over the course of the year. None did so. How large was the seasonal variation? Not much. Just 4 to 5 points, but twenty-two percent more people qualified as having high cholesterol in the winter compared to the summer. (See this table.) The truth is, we know very little about cholesterol metabolism, let alone what qualifies as "normal." And yet, we make economically significant decisions about treating minimally abnormal values. Maybe it's about time we stepped back and considered how little we know.
