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

饱和脂肪会产生低密度脂蛋白，即 LDL ，这是一种有害胆固醇。

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

对。一是你低密度脂蛋白胆固醇水平，或 LDL。

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.

但是血液中量低密度脂蛋白，即所谓“坏”胆固醇，会在动脉内部形成脂肪斑块，永久增加阻力，阻碍血液流动。

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.

当你身体传递至少有危险信号时，就存在代谢合征，包括导致腰围增大胃脂肪、高甘油酯、高血压、高空腹血糖或低高密度脂蛋白水平。

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.

它由不同类型脂蛋白携带在我们血液中，这很重要，因为它负责好胆固醇和坏胆固醇。

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，这种名为低密度脂蛋白（简称LDL）胆固醇水平升高与患痴呆症有关联。

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

但他们不能理解固醇是怎么进到血液里，包括脂蛋白将他们运送至全身各处作用。

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.

他们观察是否胆固醇被低密度脂蛋白（LDL）运送，叫做“坏”胆固醇，和高密度脂蛋白HDL，就是“好”胆固醇。

In those cells, the insulin activates lipoprotein lipase, which is an enzyme that helps those adipocytes accumulate more fat molecules.

在这些细胞中，胰岛素激活脂蛋白脂肪酶，一种帮助脂肪细胞堆积更脂肪分子酶。

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

另一是高密度脂蛋白，或称 HDL。

The answer is lipoproteins, four specialized proteins made by the liver that surround fats and allow them to move in the bloodstream as an emulsion.

答案是脂蛋白，这是肝脏制造四种特殊蛋白质，它们包围着脂肪，使它们能够以乳液形式在血液中移动。

You've probably heard of some of these. One is low density lipoprotein — also known as LDL cholesterol.

你可能听说其中一些。一种是低密度脂蛋白——也被称为低密度脂蛋白胆固醇。

Another is high density lipoprotein — or HDL cholesterol, which is the " good" cholesterol.

另一种是高密度脂蛋白——或者高密度脂蛋白胆固醇，这是一种有益胆固醇。

Lipoproteins, which is fat and water don't mix, right?

脂蛋白，即脂肪和水不相溶，对吧？

So I panicked and I went to my function health dashboard and there was lipoprotein A in rain.

于是我慌了，赶紧查看我功能性健康仪表盘，结果显示脂蛋白A在飙升。

Like, there was this really cool study on silencing that E. coli outer membrane lipoprotein gene, you know, the one called LPP.

比如， 有一项非常酷研究是关于沉默大肠杆菌外膜脂蛋白基因，你知道， 那叫做 LPP 基因。

And I saw a big story they ran on lipoprotein A, which is a type of cholesterol that is not read in almost any blood test you get at a regular checkup.

我看到他们报道了一关于载脂蛋白A大新闻，这是一种在常规体检血液检测中几乎不会被检测出来胆固醇类型。

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

它通血液中不同类型脂蛋白在体内运输，这很重要， 因为它决定了好胆固醇和坏胆固醇说法。

So, you know, high-density lipoprotein and low-density lipoprotein, you know, the HDL, the high-density lipoproteins, generally considered the good cholesterol, and the LDL, the low-density, or VLDL, very low-density lipoprotein, are considered the bad cholesterol because they're softer, right?

所以，你知道，高密度脂蛋白和低密度脂蛋白，也就是HDL，通常被认为是“好”胆固醇，而LDL，即低密度脂蛋白，或更精确VLDL（极低密度脂蛋白），则被视为“坏”胆固醇，因为它们较为松软，对吧？
