How Muchof Your Total Cholesterol Is Made By The Body, Primarily The Liver? I Heard 80% & Diet Accounts For20%
What is the source of the claim, Only about 20% of cholesterol comes from diet and about 80% is produced by the liver.” and is this true? Are the percentages correct?

I don’t really know if there is an actual percentage of cholesterol that has been determined to be derived from diet versus liver…
The usual information regarding cholesterol is as follows…
There are several factors that may contribute to high blood cholesterol:
* a diet that’s high in saturated fat and, less so, high in cholesterol (see How diet affects cholesterol below)
* lack of exercise may increase LDL (”bad”) cholesterol and decrease HDL (”good”) cholesterol
* family history – people are at a higher risk of high cholesterol if they have a direct male relative aged under 55 or a female relative aged under 65 affected by heart disease
* being overweight, which may increase LDL (”bad”) cholesterol and decrease HDL (”good”) cholesterol
* age and sex – cholesterol generally rises slightly with increasing age, and men are more likely to be affected than women
* drinking more than the recommended amount of alcohol (ie more than three to four units per day for men and two to three units per day for women)
Rarely, high cholesterol can be caused by a condition that runs in the family called a lipid disorder (familial hypercholesterolaemia). About one in 500 people have this condition.
Other health conditions such as poorly controlled diabetes, certain kidney and liver diseases and an underactive thyroid gland may also cause cholesterol levels to rise. Some medicines such as beta-blockers, steroids or thiazides (a type of diuretic) may also affect blood lipid levels..
Hope this helps….
