What is the best way to lower your cholesterol level?

While foods like eggs and shellfish contain cholesterol, cutting them from your diet is not the best thing for lowering your cholesterol level. Foods that really affect your cholesterol level are those that affect the body's _(1)_ of lipoproteins. Cholesterol is actually _(2)_ for building cells, and lipoproteins are small protein packages which carry the cholesterol produced naturally in your liver through the body via the blood stream.

The two types of lipoproteins that seriously affect cholesterol levels are low-density lipoproteins (LDLs) and high-density lipoproteins (HDLs). LDLs carry the necessary cholesterol to the body's cells. HDLs carry _(3)_ cholesterol back to the liver to be recycled or removed. Problems occur when LDLs _(4)_ artery walls and accumulate there. Accumulated cholesterol from LDLs forms thick plaque along the artery walls, which can

_(5)_ the blood flow and cause heart attacks. A high LDL count usually _(6)_ potential heart disease. Adversely, a high HDL count means your system is _(7)_ likely to be clogged up by cholesterol.

To prevent cholesterol from _(8)_, people should eat foods that lower LDLs and those that increase HDLs. Foods which _(9)_ lots of saturated fat tend to increase the level of harmful LDLs, so it's best to stay away from them. These are things like red meat, cakes, dairy products, and fried foods. Citrus fruits, soy products, fish, nuts, beans, and avocados, on the other hand, lower the body's production of LDLs and give your HDL level a _(10)_. Add these to your diet to help keep your arteries clean and cholesterol-free.

降低胆固醇的食物

什么是来降低胆固醇含量最佳的方式？

虽然蛋及贝类这些食物含有胆固醇，但从你的饮食中剔除这些东西并不是降低你身上胆固醇含量最好的方式。真正会影响体内胆固醇含量的食物，就是那些会影响体内脂蛋白生成的食物。胆固醇事实上是建构细胞不可或缺的，而脂蛋白就是细小蛋白质的堆积，会带着人体肝脏自然生产的胆固醇，透过血流遍及全身。

有两种脂蛋白对胆固醇含量影响甚巨，一种是低密度脂蛋白（LDLs），另一种则是高密度脂蛋白（HDLs）。低密度脂蛋白输送所需的胆固醇至体内的细胞。高密度脂蛋白则带着不必要的胆固醇回到肝脏循环再造或是将之清除掉。当低密度脂蛋白渗入动脉壁且累积在那里时，问题就产生了。由低密度脂蛋白所累积的胆固醇沿着动脉壁形成厚厚的血小板块，这样可能局限血流量而导致心脏病发作。低密度脂蛋白总数高的话，通常意味着潜在的心脏疾病。相反地，高密度脂蛋白总数高则表示你的循环系统不太可能会被胆固醇所堵塞。

为了避免胆固醇的累积，人们应该要吃那些会减少低密度脂蛋白的食物还有那些能提升高密度脂蛋白的食物。含有大量饱和脂肪的食物往往会增加有害的低密度脂蛋白含量，所以最好是离它们远一点。这些食物像是红肉、蛋糕、牛奶制品以及油炸食物等。而另一方面，柑橘类水果、豆制品、鱼、坚果、豆子及酪梨则会降低体内低密度脂蛋白的生成，并且提升高密度脂蛋白的含量。将这些食物加到你的日常饮食中能帮助保持动脉清洁而且不含胆固醇。
