White meat, such as chicken, may raise blood cholesterol levels as much as red meat does. This finding surprised researchers who admitted they didn't expect that eating white meat would lead to higher blood cholesterol levels. In the study, researchers looked at 113 healthy people. The participants ate three different diets: these were a red meat diet, which is primarily beef; a white meat diet, which is mostly chicken and Turkey; and a vegetarian protein diet. Each diet period was 4 weeks. Between the diet periods, participants had a break during which they ate their regular foods. In addition, participants had blood tests at the start and finish of each new diet. The results showed that white and red meat diets had the same effects on blood cholesterol levels. Further, both diets increased blood cholesterol levels compared with the diet built on vegetarian protein sources. The team acknowledged that it is possible that white meat is better for our health than red meat, despite their findings. This is because other effects of red meat consumption could contribute to heart disease, independent of cholesterol. Their main recommendations are that people eat less of both kinds of meat and more vegetarian protein.
白肉，如鸡肉，可能会使血液胆固醇水平升高，与红肉的效果相当。这一发现让研究人员感到惊讶，他们承认没有预料到吃白肉会导致血液胆固醇水平升高。在这项研究中，研究人员观察了113名健康人士。参与者食用了三种不同的饮食：红肉饮食，主要是牛肉；白肉饮食，主要是鸡肉和火鸡；以及素食蛋白质饮食。每种饮食周期为4周。在饮食周期之间，参与者有一个休息时间，在此期间他们吃自己的常规食物。此外，参与者在每个新饮食的开始和结束时都进行了血液检查。结果显示，白肉和红肉饮食对血液胆固醇水平有相同的影响。此外，与以素食蛋白质来源为基础的饮食相比，这两种饮食都增加了血液胆固醇水平。研究团队承认，尽管他们的研究发现了这一点，但白肉可能比红肉更有利于我们的健康。这是因为红肉消费的其他影响可能导致心脏病，这与胆固醇无关。他们的主要建议是，人们应该少吃这两种肉类，多吃素食蛋白质。
