Study: To Live Longer, Eat More Chicken and Plant-Based Protein 研究发现多吃鸡肉和植物蛋白有助长寿

The average American eats a lot of red meat, such as beef and meat from other mammals.

通常，美国人食用大量的红肉，如牛肉以及其它哺乳类动物的肉。

Meat-eaters often note that red meat has a lot of protein, which helps repair muscles and build bones. But new research shows that if people want to live a long and healthy life, they should get their protein from plants.

肉食主义者都了解红肉含有丰富蛋白质，有助于修复肌肉和强健骨骼。然而，新研究表明如果想要健康长寿，应该从植物中获取蛋白质。

Dr. Mingyang Song and Dr. Andrew Chan work at Massachusetts General Hospital and Harvard University. They and other researchers examined how proteins from animals and proteins from plants affect human health.

宋明阳（Mingyang Song）和安德鲁·陈（Andrew Chan）博士在马萨诸塞州总医院及哈佛大学任职。他们与研究人员试验了动物蛋白和植物蛋白是如何影响人体健康的。

They examined information from two major, long-term studies. The studies gathered information about the diet, lifestyle and health of more than 130,000 people. Dr. Chan says the information showed how to live a longer and healthier life.

他们对两项长期的重大研究的数据进行分析。这些研究记录了13多万人的饮食、生活方式和健康信息。陈博士称，这些信息告诉我们如何才能健康长寿。

One important finding was that people who ate the highest amounts of animal-based protein, such as red meat, had a higher risk of dying earlier. They were especially at risk of dying earlier from heart-related problems.

他们发现了重要的一点，食用动物类食物获取蛋白质的人早逝的风险更大。这类人因心脏相关疾病而早逝的风险更高。

One reason is that red meat has high levels of cholesterol 1, which has been linked to heart disease.

这是因为红肉含有的高胆固醇会导致心脏疾病。

The researchers found that heart-related – or cardiovascular – problems were higher among people who ate meat and also smoked, drank heavily, were obese 2 and did not exercise.

研究人员还发现，食肉、抽烟、酗酒、肥胖且不运动的人是心脏疾病或心血管疾病的高发人群。

While getting protein is important, red meat is not the only – or best – source. Dr. Chan said researchers found that people who replaced animal protein with plant protein in their diet reduced their risk of early death.

获取蛋白质固然重要，但通过红肉获取并不是唯一或最佳来源。陈博士称，研究人员发现，用植物蛋白质取代动物蛋白质的人群，其早逝的风险明显降低。
