营销话术证据 B · meta 分析
椰子油是健康超级脂肪 (MCT 燃脂)
真相
椰子油 ~82% 饱和, 主成分月桂酸 (C12) 升 LDL; Neelakantan 2020 (Circulation, 16 试验) 比植物油显著升 LDL 且不减脂, AHA 2017 明确不建议。
这话术为什么会流行
“超级食物”的媒体浪潮加上 MCT / 生酮的光环；一句名人背书就能跑赢十年的血脂数据。

Dietary fats and cardiovascular disease: A presidential advisory from the American Heart Association. Circulation, 136(3), e1-e23. 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.
