Heart & Vascular Health
Most conversations about heart disease end up being conversations about cholesterol. In our library, the loudest voices and the strongest evidence do not point the same way.
Why it matters
Cholesterol is the health subject where confident online voices have most changed what people believe. One question cuts through it, and it is not about cholesterol at all: what would actually change your decision? Nothing on this page is a reason to stop a prescribed medicine.
Key insights from this synthesis
- Our library over-represents cholesterol scepticism compared with the evidence — and one of our own topics says so plainly.
- The best argument from the sceptical side is not about cholesterol. It is that you should be told your absolute benefit before deciding on a statin. Nobody disputes that one.
- What you replace saturated fat with decides the outcome. Swap it for refined carbohydrate and the benefit disappears.
- A calcium score of zero means low risk, not no disease. The scan cannot see soft plaque at all.
- Plaque can now be measured. Whether it moved between two scans cannot — three analysis tools read the same scans and disagreed on the direction.
