In this short dialogue, two speakers argue that cholesterol is a crucial, non‑toxic element of human biology rather than a disease‑causing villain. They explain that cholesterol repairs arterial inflammation, forms cell membranes, supports hormone and neurotransmitter synthesis, and facilitates lipid transport. Citing studies, they claim people with higher cholesterol live longer and have lower rates of cancer, dementia, and infectious deaths. They note that roughly 80% of blood cholesterol is produced internally while only 20% comes from diet, and that the body compensates for reduced dietary intake by increasing synthesis. The conversation also links the low‑fat diet trend of the 1990s to spikes in diabetes, inflammatory disorders, and infertility, sharing an anecdote where women with premature ovarian insufficiency had unusually low cholesterol levels, reinforcing the functional‑medicine view that adequate cholesterol is essential for reproductive health.
I always say cholesterol is not the villain. He's like an innocent bystander that was there at the time of the shooting. Like, he was not the problem. He was actually trying to patch and repair that inflammation at the site of the artery, right?
Yes, it's an absolute essential component of human physiology. And in my deep dive long lecture, I quote studies because people just can't believe this. So I have to show the studies that people with the highest cholesterol live the longest. They have the best longevity, least amount of cancer, dementia, death from infectious diseases like pneumonia, which kills old folks. The higher your cholesterol, the longer you live and the healthier you live. Yes, because it's an essential part not only of patching up those nicks on the inside wall of your pipes, of your arteries, but it's essential for hormone production, for neuron function, and for moving the cholesterol and the fats back and forth through the So it's an essential part of the cell membrane. You cannot— you will die without this. And if you quit eating as much cholesterol, your body senses that and will ramp up production. 80% of cholesterol that your doctor's checking in your blood is from your own internal production, and we get 20% from our diet. And if you decide to eat an egg white omelet instead of the whole egg and you don't eat your cholesterol, your body's going to ramp up that production because it's such a vital component. Of human health.
I mean, when we went to that low-fat, no-fat diet in the '90s, all of a sudden diabetes started skyrocketing and all these inflammatory diseases and infertility. And I would love to just share that I used to do case review for an infertility practice. And when women had premature ovarian insufficiency or failure, meaning they just weren't ovulating anymore, they weren't able to get pregnant. Time and time again, their cholesterol numbers were so low. They would have a total cholesterol of like 100, 150, and LDL in the 80s. And it would— it just blew my mind. But it all finally made sense when I understood the functional medicine piece of it. It's like, your body needs cholesterol to make healthy cells, to have healthy hormone receptors, to make your hormones, to repair the inflammation and the damage. Like, It is vital, and your body is not gonna try and get pregnant and create another human life if you don't have this vital piece of the puzzle, right?
