You only focused on body production AND NOT about which type of cholesterol body prefers to use, and that what my message was about. From Permutter body needs all the time cholesterol from diet since it prefers to use it.
In fact dietary cholesterol is not "preferred," because absorption is poor:
Most ingested cholesterol is esterified, and esterified cholesterol is poorly absorbed. The body also compensates for any absorption of additional cholesterol by reducing cholesterol synthesis.
I already cited some medical literature sources but seems you can’t accept comments that are different from your point of view.
I already told you to buy Grain Brain by David Permutter. He is a neurologist in his book he explains why cholesterol from diet is preferred by body. He is not just a name he is a best seller author. I suppose he said something interesting for selling so many copies of his book?https://www.amazon.com/Grain-Brain-Surprising-Sugar-Your-Killers/dp/031623480X
You don’t have 13 bucks or are you too lazy read a new book?
In his book are linked all medical literature sources. I prefer to believe to a neurologist than Wikipedia...... but do as you wish.
Other authors who talk about this topic are Robb Wolf, Mark Sisson. Too much to suggest to read their books? Their are bestseller authors too...
