Most heart attacks occur in people with normal or low cholesterol: https://www.uclahealth.org/.../most-heart-attack-patients...
Cholesterol, like oxygen, is the body’s necessary defense against stressors. During peak stress, most people take more breaths. During peak stress, most livers shuttle more cholesterol into the bloodstream.
The difference, of course, is cellular function and life can exist in the total absence of oxygen. Anaerobic (oxygenless) energy and cell metabolism is a real thing. In fact, scientists insist that the origin of life on earth could have only started WITHOUT oxygen: https://www.nature.com/articles/nature06587.
Meanwhile, none of life can be explained without cholesterol. Every cell membrane requires it. Every brain function. Every heart beat. Every nerve twitch. If you have to repair more cell membranes and if you are subject to more metabolic demands, we’d hope and pray your body would produce more cholesterol to try to meet the demands, in EXACTLY the same way that we’d expect a stressed person to try to shuttle more oxygen through the body.
When people are panting, we don’t think we’ll help by taping their noses and mouths shut. We have them lie down. We ADD oxygen. When a person is getting hundreds of scabs all the time, we don’t put them on blood thinners to reduce the scabs. We try to get them to take fewer falls and injuries. But when an overstressed person is making more cholesterol, there is a tendency to only focus on that one symptom instead of the cause, the problem, or the risk.
A 21 day fast results in INCREASED blood cholesterol temporarily: https://pubmed.ncbi.nlm.nih.gov/7569738/ . Why? We added a stressor. The body SHOULD respond by raising cholesterol. The role of cholesterol is to help you live. This is definitive. Eating dietary cholesterol doesn’t do anything with regard to cardiovascular disease risk: https://www.mdpi.com/2072-6643/10/6/780. There is no mechanism in biology to turn dietary cholesterol into risk.
Removing all food RAISES blood cholesterol temporarily. Every one of the 38 trillion cells in a human body is made from cholesterol. You only have 4 million cells in your bloodstream. 38 trillion cells made of cholesterol versus 4 million cells in the bloodstream. Trillions versus millions. 200 pounds of body versus 10 pounds of blood. Pounds versus ounces.
