人们都知道胆固醇分所谓好胆固醇和坏胆固醇,而且好胆固醇越多越好,坏胆固醇越少越好。不过加拿大一项研究显示,好胆固醇的作用可能没有人们想象中大。加拿大临床评估科学研究所调查了安大略省63.1万名年龄在40岁到105岁之间的中老年人。这些人的平均年龄为57.2岁,接受调查前没有心脏病史。发表于《美国心脏病学会杂志》周刊的一篇文章称,研究结果显示,体内高密度胆固醇(好胆固醇)水平低的人更容易死于心血管并发症,这一风险并没有随着好胆固醇的增加而明显减少。
People know that cholesterol is called good cholesterol and bad cholesterol, but the better cholesterol, the better, the less bad cholesterol, the better. However, a Canadian study shows that the role of good cholesterol may not be imagined. The Canadian Institute of Clinical Evaluation surveyed 631,000 elderly people aged 40 to 105 in Ontario. The average age of these people was 57.2 years old and did not have a history of heart disease prior to the survey. In an article published in the issue of the Journal of the American College of Cardiology, the study found that people who had low levels of high-density cholesterol (good cholesterol) in the body were more likely to die of cardiovascular complications than did good cholesterol The increase was significantly reduced.
