What we're trying to avoid is this, LDL, or bad cholesterol building up as plaque in the blood vessel walls, because that plaque buildup is what can cause heart attacks.

我们要避免的是，低密度脂蛋白，或坏胆固醇，它会在血管壁上形成斑块，因为斑块的形成会导致心脏病发作。

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 ，这是一种有害的胆固醇。

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

对。一个是你的低密度脂蛋白胆固醇，或 LDL。

Biochemist and two-time Nobel Prize Winner Linus Pauling suspected Vitamin C deficiency to play a role as low Vitamin C stimulates the production of the heart disease-promoting Lipoprotein (a).

生化学家 Linus Pauling，两届诺贝得者认为，维生素 C 缺乏，可刺激人体产生大量可导致心脏病的 a 型脂蛋白。

People with a greater sense of purpose have also been shown to get better sleep, have lower levels of the stress hormone cortisol in their saliva, and have more HDL, or so-called " good" cholesterol.

研究表明，有目标感的人睡眠也好，唾液中的应激激素皮质醇低，高密度脂蛋白也多，也就是所谓的“好”胆固醇。

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度脂蛋白，即所谓的“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脂肪、高甘油三酯、高血压、高空腹血糖或低高密度脂蛋白。

You'll get up to 30 grams of fat from each of me, and 20 of those are the monounsaturated kind credited with raising " good" HDL cholesterol and lowering heart disease risk.

一个我可以给你们每人提供30克脂肪，其中20克是不饱和脂肪，它被认为能提高“有益的”高密度脂蛋白胆固醇，降低心脏病风险。

Those on short-term organic diets do show higher levels of carotenoids, polyphenols, Vitamin C and E, LDL cholesterol, antioxidant activity, immune system markers, and ever higher semen quality.

那些短期内食用有机食品的人确实体内含有多的类胡萝卜素、多酚、维生素 C 和 E、低密度脂蛋白胆固醇、抗氧化活性、免疫系统标记，以及高的精液质量。

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）的胆固醇的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的，包括脂蛋白将他们运送至全身各处的作用。

For example, this clustering phenomenon led geneticists to a gene associated with LDL cholesterol (the bad kind) and another related to inflammation.

例如，这种聚类现象导致基因学家发现了一种与低密度脂蛋白胆固醇(一种有害的胆固醇)有关的基因，另一种与炎症有关。

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多脂肪分子的酶。

One gene in particular, called ApoB, helps move cholesterol out of the blood—where it causes problems in humans—and into cells.

特别是编码为载脂蛋白B的基因有助于清除血液中对人类有害的胆固醇转变成细胞代谢。

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。

This good fat helps reduce inflammation and levels of LDL, or bad cholesterol, in the blood.

这种好油脂帮助降低血液中低密度脂蛋白也就是坏胆固醇的发炎程度。

Trans fats can increase the risk of cardiovascular disease because they boost our LDL cholesterol levels.

反式脂肪会增加心血管疾病的风险，因为它们会提高我们的低密度脂蛋白胆固醇。

The liver really doesn't want the fat sitting around inside it, so it gets converted down to something called VLDL which is stored in your fat tissue.

肝脏并的不希望有很多脂肪在里面，所以进一步把它们转换成一种叫 VLDL（极低密度脂蛋白）的东西，存在你的脂肪组织里。

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.

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

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，这是肝脏制造的四种特殊蛋白质，它们包围着脂肪，使它们能够以乳液的形式在血液中移动。
