The other one is high-density lipoprotein, or HDL.

另一个是高密白，或称 HDL。

Right. One is your level of low-density lipoprotein cholesterol, or LDL.

对。一个是你的低密白胆固醇水平，或 LDL。

Saturated fat creates low-density lipoprotein, or LDL, which is the bad kind of cholesterol.

But they didn't fully understand how cholesterol moves in our blood, including the roles of the different lipoproteins that ferry it around.

但他不能理解固醇是怎么进到血液里的，包括白将他运送至全身各处的作用。

The research team found a link between raised levels of a type of cholesterol called LDL, low density lipoprotein, and the development of disease.

该研究团队发现，这种名为低密白（简称LDL）的胆固醇水平的升高与患有关联。

They also look at whether that cholesterol is being shuttled by low-density lipoproteins or LDL, the so-called 'bad' cholesterol, and high density lipoproteins or HDL, the 'good' cholesterol.

他观察是否胆固醇被低密白（LDL）运送，叫做“坏”胆固醇，和高密白HDL，就是“好”胆固醇。

It's carried around the body in our blood by different types of lipoprotein and that's important because it's responsible for the terms good and bad cholesterol.

它由不同类型的白携带在我的血液中，这很重要，因为它负责好胆固醇和坏胆固醇。

Metabolic syndrome exists when you have at least three risk factors, including excess stomach fat contributing to an enlarged waist size, high triglycerides, high blood pressure, high fasting blood sugar or a low high-density lipoprotein level.

当你的身体传递至少有三个危险信号时，就存在代谢综合征，包括导致腰围增大的过多胃肪、高甘油三酯、高血压、高空腹血糖或低高密白水平。

But an excess of low-density lipoprotein, or LDL, the so-called " bad" cholesterol, in the blood can build up to form a fatty plaque on the inside of your arteries, permanently increasing the resistance, and hindering blood flow.

但是血液中过量的低密白，即所谓的“坏”胆固醇，会在动脉内部形成肪斑块，永久增加阻力，阻碍血液流动。
