Cholesterol is actually necessary. And your body already makes it.
Cholesterol is a type of fat made by your liver -- it plays a role in creating vitamin D, and maintains cell membrane health. Basically, you really need cholesterol if you want to be a functioning human, and your body does a fine job producing it.
You can also find cholesterol in food, but eating high-cholesterol foods doesn’t mean your blood cholesterol levels will increase. And some people simply make more cholesterol than others. “Everyone’s body is different, and you don’t know how much cholesterol your body is going to make,” says cardiologist Dr. Nicole Weinberg.
In other words, it's possible to have naturally high cholesterol, even if you eat an extremely healthy diet… or you could have pretty low cholesterol, in spite of dining on egg yolks, burgers, and milkshakes all day.
