Actually, studies have shown that the longest living people on the planet, when they pass, their cholesterol level is around 250.
I remember seeing an article by a doctor who had performed thousands of cardiovascular surgeries. He stated that every single patient suffered from inflammation of the vessels and opined that absent the inflammation, no elevated level of colesterol would be problematic. Cure the inflammation, and the colesterol would freely flow.
ps - curing the inflamation is done through diet - processed flower is the #1 killer. If everyone's diets were predominently whole foods, we wouldn't have but a tiny fraction of the problems we have today.
