If you don't eat enough cholesterol your liver makes the rest.
It wouldn't do this if cholesterol was the enemy.

The best analogy I've heard: blaming cholesterol for heart issues is like blaming the firefighters for a structure fire. Just because they're on the scene doesn't mean they caused it
There is more than one kind of cholesterol.
I knew your body regulates cholesterol, I didn't know it was the liver. Is it correct that 80% of your body's cholesterol is created by your liver?
Also, if you don't eat enough carbohydrates, your body makes them from protein. It wouldn't do this if carbohydrates were the enemy.
