Coconut oil isn’t healthy; it never was

The American Heart Association recently released a report advising against the use of coconut oil.

The Dietary Fats and Cardiovascular Disease advisory reviewed existing data on saturated fat, showing coconut oil increased LDL (“bad”) cholesterol in seven out of seven controlled trials. Researchers didn’t see a difference between coconut oil and other oils high in saturated fat, like butter, beef fat and palm oil.

In fact, 82% of the fat in coconut oil is saturated, according to the data — far beyond butter (63%), beef fat (50%) and pork lard (39%).

“Because coconut oil increases LDL cholesterol, a cause of CVD (cardiovascular disease), and has no known offsetting favorable effects, we advise against the use of coconut oil,” the American Heart Association said in the Dietary Fats and Cardiovascular Disease advisory.

Frank Sacks, lead author on the report, said he has no idea why people think coconut oil is healthy. It’s almost 100% fat. Past weight loss studies might be responsible.

“The reason coconut oil is so popular for weight loss is partly due to my research on medium chain triglycerides,” Marie-Pierre St-Onge, associate professor of nutritional medicine at Cornell University Medical School, told TIME in April. “Coconut oil has a higher proportion of medium-chain triglycerides than most other fats or oils, and my research showed eating mediumchain triglycerides may increase the rate of metabolism more than eating long-chain triglycerides.”

Coconut oil can still be an effective moisturizer or hair conditioner.

“You can put it on your body, but don’t put it in your body,” Sacks said.
