Our body makes seventy to eighty percent of the cholesterol in your blood. Only twenty to thirty percent of the cholesterol in your body comes from your diet.
So why does our body produce excess cholesterol?
Cholesterol is part of the structural framework for every cell in our body.
When our body is producing excess insulin this stimulates the production of excess cholesterol.
Our body is producing the excess cholesterol so it can make the new cells needed to store fat.
What stimulates the body to produce excess insulin and go into fat storing mode?
Foods that convert quickly into glucose in your body (foods high on the glycemic index) stimulate the production of insulin to regulate your blood glucose level.
Too much of this type of food (high on the glycemic index) means the release of too much insulin which puts your body into fat storage mode.
This fat storage mode produces too much cholesterol.
So eating a diet low in cholesterol will not significantly reduce your blood cholesterol levels.
93% of the body's cholesterol is actually inside the cells of the body. Only 7% is circulating around in your blood.
When your diet is low in cholesterol your liver produces more. When your diet is rich in cholesterol your liver produces less.
This is why eating less cholesterol will have little effect on the level of cholesterol in our body.
Unfortunately cholesterol levels are regulated inside the cells. Your body does not regulate the level of cholesterol in your blood. Excess cholesterol in the blood can contribute to the clogging of arteries.
The body regulates the level of cholesterol in the cells, not in blood.
There are two kinds of cholesterol, LDL, the bad cholesterol and HDL, which is the good cholesterol.
LDL cholesterol, the bad cholesterol, is fine and essential in your cells. It only causes problems in your blood.
LDL cholesterol is either made in your cells or LDL receptors gather the cholesterol into your cells from your bloodstream.
If the cells are producing more cholesterol they will gather less cholesterol from the blood.
If your cells are producing less cholesterol they will gather more cholesterol from the blood.
The one which causes the cells to produce too much cholesterol is the insulin.
Insulin stimulates a hormone called HMG-CoA reductase which controls the production of cholesterol in the cells.
Reducing insulin to a healthy level with the diet and exercise should also reduce the levels of LDL or bad cholesterol in your blood.
HDL or good cholesterol takes cholesterol from your tissues including the lining of your arteries and sends it back to your liver.
This could obviously reduce the chance of arteries being clogged.
Therefore, it is necessary to have a higher level of HDL or good cholesterol in the blood and also a lower level of LDL or bad cholesterol in the blood.
So as a basic guideline:
- Keep your total cholesterol divided by HDL cholesterol below 4.
- Keep the LDL cholesterol divided by HDL cholesterol below 3.
- The ideal level of overall blood cholesterol is probably around 180mg/dl to 200mg/dl. A blood cholesterol level too high or too low can be hazardous.
Eating enough essential fatty acids or good fats like those found in fish, eggs, almonds can help your body produce more HDL or good cholesterol.
So, therefore eat foods low on the glycemic index like the pig out freely foods.
This should help decrease your level of insulin and in turn your levels of LDL or bad cholesterol.
