"Don't eat so many eggs, it's not good for your cholesterol!" – Have you ever heard this before? It's generally known that high cholesterol isn't good, but why exactly? We've taken a closer look at the topic of "lowering cholesterol" and will explain the difference between good and bad cholesterol, why cholesterol is vital, and how you can lower your cholesterol.
Interesting facts about cholesterol
Cholesterol is a fat-like substance found in almost all cells of a healthy person. As a structural component within cells, cholesterol is essential for life. Furthermore, cholesterol is an important precursor for the formation of vitamin D and hormones (e.g., the sex hormones testosterone and estrogen). It is also required for the production of bile acids for fat digestion .
What many people don't know: A healthy body synthesizes its own cholesterol – precisely the amount needed to perform its functions. Additional cholesterol ingested through food (primarily from animal products) naturally reduces this endogenous production. Nevertheless, consistently high cholesterol intake can have negative health consequences.
"Good" and "bad" cholesterol
You have almost certainly heard of the categorization into "good" and "bad" cholesterol – these are LDL and HDL cholesterol.
To distinguish them: Both are so-called lipoproteins, a combination of fat and protein . Fats and fat-like substances are hydrophobic (water-insoluble). Therefore, lipids like cholesterol can only be transported by the blood if they are bound to a water-soluble substance. The solution: a bond with proteins. Depending on the ratio of fat to protein, a distinction is then made between LDL and HDL cholesterol.
LDL transports cholesterol into the arteries , where it can cause blockages . HDL transports cholesterol to the liver for breakdown . The classification as "good" and "bad" is therefore based on several factors.
