🧬 Why does our body make cholesterol?
The moment many people hear the word “cholesterol,” they think:
❌ BAD!
But cholesterol itself is actually an essential raw material for the body.
Our cell membranes need it, it plays a role in making certain hormones, and it is involved in the production of vitamin D.
💡 So perhaps the real question isn’t simply, “Is cholesterol good or bad?”
It’s about understanding:
Why does our body need it? Where does it go?
And when can it become a problem?
Think of LDL and HDL as part of the body’s cholesterol transportation system:
🚚 LDL delivers cholesterol to where the body needs it.
♻️ HDL helps transport remaining cholesterol back to the liver for processing.
So rather than simply labelling LDL as “bad,” we should understand the bigger picture of cholesterol metabolism and cardiovascular health.
👉 Then why has LDL been called “bad cholesterol”?
👉 What is the real “bad guy” we should be paying attention to?

🧬 身体为什么要制造胆固醇？
很多人一听到「胆固醇」三个字，就马上想到——坏东西！
但你知道吗？胆固醇其实是身体维持正常运作的重要原料之一。
细胞膜需要它，身体制造部分激素也需要它，维生素D的合成过程也与胆固醇有关。
💡 所以，问题不是简单的「胆固醇好不好」，而是
身体为什么需要它？它去了哪里？为什么会成为问题？
而 LDL 与 HDL，其实更像是身体里的「运输系统」：
🚚 LDL 负责把胆固醇运送到身体需要的地方；
♻️ HDL 则参与把胆固醇带回肝脏处理。
真正值得我们关注的，是整个胆固醇代谢系统，而不是看到 LDL 就马上把它贴上「坏」的标签。
👉 那为什么 LDL 长期以来会被称为“坏胆固醇”？
👉 真正需要警惕的，到底是什么？
