If you were born in the 80’s or 90’s you better sit down for this one. It’s going to sting.
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 and found coconut oil increased LDL (“bad”) cholesterol in SEVEN out of SEVEN controlled trials. Researchers saw NO difference between coconut oil and other oils high in saturated fat, like palm oil, beef fat, or butter. In fact, 82% of the fat in coconut oil is saturated, according to the data — far beyond butter at 63%, beef fat at 50%, and pork lard at 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.
The report’s lead author, Frank Sacks, 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 medium-chain triglycerides may increase the rate of metabolism more than eating long-chain triglycerides.”
St-Onge’s research may be a little flawed as they used an oil packed with 100% MCTs. Traditional coconut oil only contains about 13 to 15%. Another study she published showed smaller doses of MCTs doesn’t help with weight loss in overweight adolescents.
The AHA recommends eating no more than 6% of saturated fat as part of total daily calories for those who need lower cholesterol.
But, before you throw out all of your coconut oil, you may want to further investigate the meaning of saturated fat. While the AHA warns against it, people who cut saturated fat out of their diet didn’t necessarily lower their heart disease risk, a 2015 BMJ review suggested. That’s because some people fill the void with sugar, white flour, and empty calories. Also, some fat is important to help bodies absorb nutrients from other foods.
Still, Stacks says opting for vegetable oils or olive oil might not be a bad idea. Plus, coconut oil can still be an effective moisturizer or hair conditioner.
