Dietary cholesterol has little impact on blood cholesterol. And higher blood cholesterol is associated with lower mortality in men, and no correlation in women. The sweet spot for total cholesterol seems to be about 240 total, with higher HDL being better - but it's just a correlation. It was never a cause. Without providing dietary cholesterol, the liver is forced to synthesize it. This is stressful and could shorten the lifespan. Traditional cultures free of modern disease/western diseases eat cholesterol-rich food daily, as well as lots of plants and often insects. Look at eggs. You can eat a dozen a day and it does nothing bad to you at all. And why? Because cholesterol is good for you to eat. It repairs cells, it's going to be there anyway even if your liver has to make it, and you might as well provide it like a responsible eater.
Saturated fat is also a safe food. What do you think your body burns for fuel when you skip a meal or two? That's right. The saturated fat your body is covered with. Why would you naturally store and use poisonous energy?
Vegans kill more animals than locavores. Eating one local cow, or a few sheep, chickens, pigs, etc. is nothing to the demolition of the amazon for the soy and other crops veganism demands. One cow is one cow. A box of cereal easily represents 30 dead mice, or other life that was forever wiped from the earth to plant GMO monocrops for Monsanto. And these are the foods most strongly correlated with heart disease. Corn, wheat, soy and products made from them are the staple foods of western peoples. Vegetable oil is just oxidized, rancid omega-6 oils from corn and soy. It hardens the arteries. Animal fats do no such thing.
