Well we’d all die without cholesterol, why do you think our bodies make it?
Anyone talking in terms of risk from Total Cholesterol is at least 20 years out of date.
Anyone talking about risk from good versus bad cholesterol is 10 years out of date.
For at least 10 years we have known that particle size is very important as large particles can’t get through the endothelium.
Unfortunately the NHS is very out of date and doesn’t provide LDL-p tests (that measure particle size), so you have to get it done privately. More advanced countries like Australia do this routinely.
There is no such thing as “bad cholesterol” - there is however “potentially problematic” cholesterol.
Potentially problematic cholesterol is small particles of LDL - either oxidised particles, particles such as LP(a) which are a genetic variant that can’t be recycled or small triglyceride lipid remnants that contain cholesterol.
Large particles of LDL that can be recycled are actually healthy.
Cholesterol is only ever a problem when the arteries have been damaged by smoking or decades of high blood sugar levels from refined carbs.
Dietary cholesterol usually makes up a relatively small amount of the cholesterol in our bodies - our liver makes 75% or more of it.
Half of the people who have heart attacks have low cholesterol - including low amounts of the so-called “bad” type.
Statins work to reduce the cholesterol your liver makes, but they have zero impact on CVD risk. All cause mortality for example is not improved by statins.
The only reason people should be put on statins is for secondary prevention, and even then the benefit is not the cholesterol reduction but the reduction in cardiovascular inflammation that statins have.
But what if someone has the genetic LP(a) that results in high choleserol readings? (25% of the population have this). The answer is lifestyle changes have no effect on it, and statins are of no help either as it just builds up due to not being bale to be recycled. The only real option these people have is a PCSK9 inhibitor drug - thesee are relatively new (released in the last couple of years) or taking flush type Niacin (usually 1 mg or 2 mg day) - this is what used to get prescribed for high cholesterol by doctors before statins were invented.
I have researched this subject extensively since I had a heart attack and 3 stents put in 4 years ago. If you like watching videos, look for Thomas Dayspring ( worldwide lipid expert) and Ford Brewer (for preventative medicine).
