๐ฏLDL is the "bad" cholesterol that clogs arteries. Optimal is under 100 (under 70 if you're high-risk); 130โ159 is borderline, 160+ is high. Lower is better.
๐ขHDL is the "good" cholesterol that clears LDL away โ you want it higher (40+ for men, 50+ for women). Exercise and healthy fats raise it.
๐ดTriglycerides are blood fat raised by sugar, refined carbs and alcohol โ keep them under 150.
๐ฅSaturated & trans fat (fatty meat, butter, fried & processed food, pastries) push LDL up. This is the biggest dietary lever.
๐พSoluble fiber (oats, beans, lentils, fruit) and healthy unsaturated fats (olive oil, nuts, avocado, salmon) pull LDL down and raise HDL.
๐Statins are the workhorse โ they cut LDL ~30โ50%. Ezetimibe blocks absorption, a PCSK9 injection drops it hard, and fish oil mainly lowers triglycerides. Diet + statin together get most people to goal.
๐ซArtery Health is the consequence. Every day spent with high LDL builds plaque in your arteries; keep it low and your arteries slowly recover. Let it hit zero and you have a heart attack.
