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 , 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 Columbia University Medical Center, 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.”
The problem is St-Onge’s research used a “designer 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.
Before you trash your coconut oil, know that saturated fat is a loaded term. While the AHA warns against it, people who cut saturated fat out of their diet might not 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. Many have said butter has gotten a bad reputation.
Still, it might not be a bad idea to opt for vegetable oils or olive oil, Sacks said. Plus, 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. en
When shopping for a healthy oil, Hensrud said go for one with high levels of monounsaturated or polyunsaturated fats. Both are considered healthy fats that lower cholesterol.
Also, avoid partially hydrogenated oils — that’s the source of trans fat, which raises bad cholesterol.
Here are some of the healthiest oils, as recommended by doctors and researchers:
High in monounsaturated fats: is the shining star of healthy oils in this group. Many experts point to a study in The New England Journal of Medicine that enrolled 7,447 people ages 55 to 80-years-old and showed eating olive oil (or nuts) greatly reduced the risk of cardiovascular disease. Research also suggests olive oil could help reduce the chance of breast cancer.
The type of olive oil can matter. has slightly more nutrients, Hensrud said. Sediment in the bottle could actually translate to vitamin E.
, which contains 71% monounsaturated fatty acids, has become a popular choice, and experts say for good reason. It has some of the same properties as olive oil, plus it has a high smoke point — meaning, it’s safe to cook at high temperatures. Oils with low smoke points create toxic compounds when overheated (think: frying). Safflower and sunflower oils also contain high amounts of monounsaturated fats and have high smoke points (above 400 degrees).
Canola & Peanut Oils
High in polyunsaturated fats: The American Heart Association’s Dietary Fats and Cardiovascular Disease advisory showed is best for baking because it’s largely tasteless and peanut oil is good for frying because of its high smoke point.
