Danish researchers studied 25,764 people in Copenhagen whose average age was 59. All had blood drawn regularly to test lipid levels.
Average total cholesterol in the group for the whole year was 205, just over the recommended guideline of 200. Average LDL, or ‘‘bad’’ cholesterol, was 116, just above the recommended 100 level.
But for 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.
The senior author, Dr. Anne Langsted, said lack of exercise and indulgence in high-fat food could be to blame. But, she said, ‘‘A steady high cholesterol is what’s dangerous. We can’t say for sure, but the peaks at Christmas may not be so important if you have a good level the rest of the year.’’
