It's a dietary fad, a "superfood" and sometimes even used to remove makeup, but according to one Harvard University professor, coconut oil is nothing but poison.
People are recommended to avoid the high levels of saturated fatty acids found in coconut oil.
This warning could come as a shock to advocates of the thick, fatty stuff, who use it not only for cooking but also blend it into their morning cup of coffee.
Her lecture, titled Coconut Oil and other Nutritional Errors, was widely shared by those concerned that coconut oil is actually not as healthy as was previously thought.
Coconut oil reached it's peak popularity in 2015 when it was considered the trendy superfood that was guilt-free and rich in health benefits.
Dr Michels also added that other "superfoods" like acai or chia seeds contain the same nutrients you can get much more easily by eating carrots, cherries or apricots.
"We are well and sufficiently supplied", she said.
In a speech given at the University of Freiburg in Germany, Dr Karin Michels suggested the oil isn't deserving of its healthy reputation, due to it containing high levels of unsaturated fatty acids. Because of its anti-inflammatory effects and absorbent nature, coconut oil is a great topical remedy or those who suffer from dry skin.
According to the AHA report "The Skinny on Fats", the new guidelines urge consumers to limit both saturated and trans fats.
The AHA found that replacing saturated fat intake with polyunsaturated vegetable oil greatly reduced the risk of developing cardiovascular disease, similar to the numbers achieved by prescribed drug treatment. Most worldwide dietary guidelines recommend enjoying saturated fats in moderation.
"But the reality is when you look at what coconut oil is made of, 80 percent of it is saturated fat and that's similar to butter which is about 60 percent saturated fat or beef fat which is about 40 percent", CBS News medical contributor Dr. Tara Narula told "CBS This Morning" a year ago.
"There has been speculation that some of the saturated fat present in coconut oil may be better for us than other saturated fats, but so far there is not enough good-quality research to provide us with a definitive answer". It's just that you have to be aware that most health claims about this food have been greatly exaggerated.
