Is Cholesterol Bad?
Cholesterol: is it a good thing or a bad thing?
Well the short answer is that it (can be) both. One thing we know for sure is that Atherosclerosis, which is the “hardening of the arteries”, is a process that happens to everyone and will eventually lead to disorder like stroke, heart attack, or dementia. Atherosclerosis, we could argue, is the number 1 killer in North America.
What is Cholesterol?
What is it? Cholesterol is a building block for many things in our bodies: it’s a pre-hormone, it helps with membrane fluidity, and it our nervous systems need it. Overall, cholesterol is required for us to function in a healthy manner, but it can be involved in an unhealthy process: Atherosclerosis. How does it get high?
Cholesterol, as it turns out, is only partially absorbed from our diet; there are also many things in food that reduce its absorption (fibre for example). An average amount of dietary cholesterol absorption is ~125mg per day. (1) Our bodies synthesize about 1,000mg per day, which means only 11-12% of our cholesterol comes from our diets. The rest has to do with how much is made in the body and, more importantly, how much is recycled.
