As more HDL counteracts the effects of LDL.

更多的高密度会抵消密度的影响。

If you've ever had a cholesterol test, you'll know it's the ratio of HDL to LDL that matters.

如果你做过胆固醇测试，你就会知道高密度和密度的比例很重要。

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

饱和肪会密度，即 LDL ，这是一种有害的胆固醇。

Now it's a bit of a mystery why HDL should turn bad when it goes really high.

这有点神秘——为么高密度非常高时会变坏？

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

这种好油帮助降血液中密度也就是坏胆固醇的发炎程度。

Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol.

此外，酮饮食还降了患者体内的甘油三酯、密度胆固醇及血糖水平，增加了高密度胆固醇水平。

For women, the risk climbed once HDL levels topped 100.

对女性来说，一旦高密度水平超过 100，风险就会攀升。

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

对。一个是你的密度胆固醇水平，或 LDL。

So, is it possible to have too much HDL?

高密度太多也可能出问题吗？

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

反式肪会增加心血管疾病的风险，因为它们会提高我们的密度胆固醇水平。

There's a difference between where men and women enter the HDL danger zone.

男性和女性的高密度危险区是有区别的。

It increases your bad LDL cholesterol, and it decreases your good HDL cholesterol.

它会增加你的坏密度胆固醇，并降你的好高密度胆固醇。

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，胰岛素激活肪酶，一种帮助肪细胞堆积更多肪分子的酶。

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。

The only real difference was a small difference in LDL.

唯一真正的差异是密度（LDL）的微小差异。

Whereas saturated fat as a whole tends to raise LDL cholesterol.

而饱和肪作为一个整体往往会提高密度胆固醇。

I've read that estrogen can increase HDL in women, and that it can be protective.

我之前读到过，雌性激素可以增加女性的高密度，并且高密度有保护作用。

HDL is important because it's a marker of metabolic health.

高密度很重要，因为它是代谢健康的标志。

For men, cardiac and other disease risks went up if their HDL levels were under 40 — or over 80.

对于男性来说，如果他们的高密度水平于 40 或高于 80，心脏病和其它疾病的风险就会上升。

The teaching has been up until recently, that the higher the HDL, the lower the risk.

直到最近，教学上一直这样说：高密度越高，风险越。
