What people think happens in your arteries when you eat saturated fat:
- The fat enters your blood
- It slides along the arterial wall
- It sticks and builds up like limescale in a kettle
- Heart disease follows at a sensible pace
What actually happens:
- Saturated fat is packaged into transport molecules and delivered to cells that need it
- It doesn't touch the arterial wall the way the cartoon implies
- LDL is a transport molecule, not a dietary fat: it carries nutrients to cells
- Arterial disease is an inflammatory injury-repair process
- Oxidised fats are the pathological actor: not saturated ones
- Polyunsaturated fats oxidise far more readily than saturated fats
- The fat in the artery is not the fat on your plate: they just share a name
The kettle limescale model is intuitive.
It is also completely wrong.
Atherosclerosis is an inflammatory disease.
The butter didn't start the fire.
