Too much bad cholesterol in the blood clogs arteries and can cause heart attacks.
See the scientific wording
Elevated low-density lipoprotein (LDL) cholesterol levels directly promote atherosclerotic plaque formation, increasing the risk of cardiovascular events.
Correlational — new studies may shift this
2 low-scoring studies link this claim to the outcome, but causation is not established.
What the research says
2 studies reviewedSupporting (2)
Narrative ReviewReview2024
This study shows that lowering 'bad' cholesterol (LDL) with medicine reduces heart attacks and strokes, which means high LDL really does contribute to clogged arteries—just like the claim says.
Narrative ReviewReview2025
This study shows that when there’s too much of certain types of 'bad cholesterol' (LDL), especially when they’re small, sticky, or damaged, they get stuck in artery walls and cause dangerous buildups—exactly what the claim says.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

- 1
We isolate the claim
Health advice from videos, articles and studies is broken down into single, testable claims.
- 2
We find the research
Each claim is matched against peer-reviewed studies, with every source cited by DOI.
- 3
We grade the evidence
Studies are scored on methodology, statistical rigor, transparency and publication quality.
The fitness and health internet is full of confident claims. We check them against real research.
Every claim on this site is traced back to peer-reviewed studies, scored on methodology and reporting quality, and given a verdict you can audit yourself — sources, DOIs and all.
