С малката разлика, че LDL и HDL са две съединия на холестерола. Той си е един и същ. както има вода има и тежка вода. Има въглероден моноксид и въглероден диоксид.

Отнову пускам същия цитат.
* Why does your liver make sure that you have plenty of cholesterol?
* Why is HDL taking cholesterol back to your liver?
* Why not take it right to your kidneys, or your intestines to get rid of it
?
Ако HDL найситна беше "добър" би следвало да носи мазнините към бъбреците и от там да се изхвърлят от тялото.

Because the correlation of total cholesterol with heart disease is so weak, many years ago a stronger correlation was sought. It was found that there is so-called "good cholesterol" called HDL, and that the so-called "bad cholesterol" was LDL. HDL stands for high-density lipoprotein, and LDL stands for low-density lipoprotein. Notice please that LDL and HDL are lipoproteins -- fats combined with proteins. There is only one cholesterol. There is no such thing as a good or a bad cholesterol. Cholesterol is just cholesterol. It combines with other fats and proteins to be carried through the bloodstream, since fat and our watery blood do not mix very well.

One function of cholesterol is to keep your cell membranes from falling apart. As such, you might consider cholesterol your cells "superglue." It is a necessary ingredient in any sort of cellular repair. The coronary disease associated with heart attacks is now known to be caused from damage to the lining of those arteries. That damage causes inflammation. The coronary disease that causes heart attacks is now considered to be caused mostly from chronic inflammation.
Тоест холестерола предпазва от коронарни проблеми. Яко а?

И в заключение искам отново да натъртя, че холестерола далеч не е толкова вреден. Много високите му нива са следствие най-вече от заседнал живот. Мисля, че на всички е ясно, че свръхвисоките нива на каквото и да е не са полезни. Не твърдя, че панацея, просто хранането не влияе на нивата му!
