LDL isn't bad cholesterol—it's a delivery truck that brings cholesterol where the body needs it.
Scientific Claim
Low-density lipoprotein (LDL) functions as a transport particle that delivers cholesterol and other essential lipids to peripheral tissues via the bloodstream.
Original Statement
“LDL is actually a carrier of cholesterol. Specifically, LDL is a particle that carries cholesterol and other essential molecules throughout our blood to wherever they need in the body.”

This paper says LDL is made in the liver to carry essential fats and cholesterol through the blood to where the body needs them — exactly what the claim says.
Technical explanation
This paper directly states that VLDL (which matures into LDL) packages cholesterol and triglycerides in the liver and transports them to peripheral tissues via the bloodstream — precisely matching the assertion. It describes LDL’s physiological purpose as lipid delivery, with no deviation from the core claim.
This study shows that LDL is like a delivery truck that carries cholesterol from the liver to other parts of the body, which is exactly what the claim says.
Technical explanation
This paper explicitly states that LDL delivers cholesterol from the liver to peripheral tissues, directly supporting the assertion. It focuses on LDL's structural role in lipid transport and its interaction with receptors, which is central to the mechanism described in the assertion.
