Cholesterol is only one dietary factor that has to be considered in avoiding a cardiovascular event. You can have low cholesterol and still have a heart attack or a stroke. You can have high cholesterol and not.
I suggest you watch this free online streaming video from Dr. Greger ( the "vegan md" now the medical director at Humane Society Of The United States).
You can even watch it on dial-up.....I have.
Even if you eat meat it will be the one of the most well spent hours of your year as it will teach how to prevent heart attacks and strokes with managing nutrients often not mentioned, but that count as much as cholesterol.
