when we go for blood test check, we see the cholesterol, HDL = (good fat) and LDL = (bad fat) I would like to know exactly what are the differences between these 3 catogories or types of fat?
are HDL and LDL type cholesterol as well? what is the function of each of them or come from what? and how to increase or reduce each of them? and what are the risk levels of each of them when higher or lower the optimal range? I will appreciate any advices..
many thanks in adavnce,
This is an incredibly detailed and long explanation. I’ll try to cover the surface and find you some links.
HDL and LDL aren’t cholesterol (C) themselves, think of them as cholesterol carrying "bottles". The third fat on you saw on your blood test was probably triglyceride (TG).
The different between HDL and LDL is simply how much "cholesterol ester"(CE) it has (it’s actually much more complicated than that but let’s keep it simple). CE are safer for the body since it doesn’t damage things that it touches and HDL has more of it. While LDL has more C, which can damage other cells it touches.
The other issue is that LDL has marker on it’s surface called APO-B100… this marker can get damaged easily by toxin. Once the marker is damaged the LDL can never come back to liver again. So now it is forced to roam around in the blood until it eventually dies and gives us a atherosclerosis. HDL can save the day by finding these dead and collecting the C from them before they cause any problems and returning it back to the liver.
TG are like storage forms of fat. It’s what you think of when you talk about fat around the waist.
This was a really vague explanation. But I think I probably already lost most people, so saying more would be to no avail.
Hope that made sense, if you still have more specific questions drop me a message and i’ll try to help.
