Coconut oil

Studies show that coconut oil increases harmful cholesterol (LDL -low-density lipoprotein) and beneficial cholesterol (HDL - high-density lipoprotein). They also contain a high amount of lauric acid, which raises HDL levels in the blood more than LDL levels.

But lauric acid is not that healthy. It is categorized as a C12 fatty acid and is at the limit of a medium-chain fatty acid. Roughly 70% of C12s act as long-chain fatty acids, which are stored in the liver as fat, and over time, can cause nonalcoholic fatty liver disease.
