correct i would worry more about simple sugars and sat fat causing increased chol biosynthesis(ldl) and less reverse transport.
dietary cholesterol has minimal effect.
some have proposed that chol isnt even bad, that it is a response to viral or bacterial infection within the body.
What people refer to as good cholesterol and bad cholesterol are not
really cholesterol at all. They are actually carrier proteins that
act like "baskets" to transport cholesterol between the blood and the
liver. The "bad" form is low-density lipoprotein, which carries
cholesterol from the liver, where it is made, to the blood. It is
considered bad because too much cholesterol in the blood slowly clogs
arteries, eventually causing heart disease. On the other hand, what
is termed "good" cholesterol is a high-density lipoprotein that
transports cholesterol from the blood to the liver.
Your body makes cholesterol because it is a building block for a
number of essential substances. These include:
* Pre-vitamin D, which is converted by sunlight to vitamin D
* Testosterone, the "male" sex hormone
* Estrogen, the "female" sex hormone
* Progesterone, a sex hormone found in both males and females
* Bile salts, that nasty yellow stuff that comes up with severe
nausea
Other critical steroid hormones that help to regulate such important
things as potassium and sodium levels
Excess cholesterol is "stored" in the blood. The actual cholesterol
levels are determined by a number of factors, including heredity,
diet and exercise. Diet appears to be the most important of these.
Your body produces three to four times more cholesterol than you
eat. The production of cholesterol increases when you eat little
cholesterol and decreases when you eat much. This explains why
the "prudent" diet cannot lower cholesterol more than on average a
few per cent.
Cholesterol (fat) is needed in order to decrease increased cholesterol levels. Eating good fats is one way to increase the HDL. As well, if they are eating a lot of carbs, this will have an effect on their insulin level, which effects the liver, which will convert excess sugar into LDL.
When you don't have enough cholesterol, the body releases a hormone that signals the liver to start to overproduce cholesterol. The less fat they eat and the more carbs they eat, the more they keep producing. It becomes a vicious cycle.
