Karin Michels, of the Harvard T.H. Chan School of Public Health, spoke out against coconut oil in a 50-minute YouTube video that has since gone viral. It was, she said, "one of the worst things you can eat".
"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", said Victoria Taylor, a senior dietician at the British Heart Foundation.
And coconut oil raises the risk for heart disease.
A video released on Youtube about coconut has gone viral and almost crossed 1 million views. The group found that only 37 percent of certified nutritionists agreed that coconut oil is healthy.
He says you don't want to layer coconut oil with other saturated fats. It's been tied to fat-burning and hunger-curbing, though there's no study to support those beliefs.
Previously, coconut oil was considered a useful product.
Let's take a second to chat about... coconut oil.
Distribution of coconut oil began in the early 2000s after two research scientists at Columbia University have shown beneficial effects of fatty acids contained in the coconut. As CNNreports, almost three-quarters of Americans believe coconut oil to be healthful. This disconnect between lay and expert opinion can be attributed to the marketing of coconut oil in the popular press. The oil has "no known offsetting favorable effects", the AHA said in an advisory a year ago, and it could actually increase LDL ("bad") cholesterol, a cause of cardiovascular disease.
Doctors say this comparison is not valid because their traditional diets also include more fish, fruits, and vegetables than typical American diets.
