The claimEvidence B · meta-analysis
Coconut oil is a healthy superfat (MCT fat-burner)
The evidence
Coconut oil is ~82% saturated and its lead fatty acid lauric (C12) raises LDL; Neelakantan 2020 (Circulation, 16 trials) shows it raises LDL vs vegetable oils and burns no fat — AHA 2017 advises against it.
Why the claim spreads
A 'superfood' media wave plus the MCT / keto halo; one celebrity endorsement can outrun a decade of lipid data.
The mechanism, in brief
Coconut oil's effect on blood lipids is one of the rare debunking topics where the evidence is fairly consistent.

Coconut oil is ~82% saturated; the AHA advises against its use because it raises LDL-C with no known offsetting favorable effect, and recommends replacing saturated with unsaturated fat.
- Science Feedback. (2019). Current scientific evidence doesn't demonstrate that coconut oil prevents or treats Alzheimer's. Reviewers concluded only a few small pilot studies exist and no rigorous human trial supports coconut oil preventing or treating Alzheimer's disease; the ketone hypothesis remains unproven clinically.
