As more HDL counteracts the effects of LDL.

更多的高密度脂蛋白会抵消低密度脂蛋白的影响。

So, is it possible to have too much HDL?

高密度脂蛋白太多也可能出问题吗？

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

对女性来说，一旦高密度脂蛋白水平超过 100，风险就会攀升。

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，你就会知道高密度脂蛋白和低密度脂蛋白的比例很重要。

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，如果他们的高密度脂蛋白水平低于 40 或高于 80，心脏病和其它疾病的风险就会上升。

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

男性和女性的高密度脂蛋白危险区是有区别的。

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：高密度脂蛋白越高，风险越低。

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

这有点神秘——为什么高密度脂蛋白非常高时会变坏？

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

此外，生酮饮食还降低了患者体内的甘油三酯、低密度脂蛋白胆固醇及血糖水平，增加了高密度脂蛋白胆固醇水平。

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脂蛋白，并且高密度脂蛋白有保护作用。
