Reduction in exercise and indulgence in high-fat food during Christmas holidays may be to blame. But constant high cholesterol is what’s dangerous. We can’t say for sure, but the peaks at Christmas may not be so significant if you have a good level for the remaining of the year.
Danish researchers studied 25,764 people in Copenhagen whose average age was 59, none of whom were on cholesterol-lowering medicines. Nevertheless, over three successive years in the first week of January, the average cholesterol was 240, and the average LDL was 143, both well into the unhealthy range. In June, the average cholesterol was 197, and the average LDL was 108. Almost twice as many people had unhealthy lipid levels in January as in June.
