Coconut oil, according to recent reports, is the latest food cure-all. Claims abound that coconut oil is a health food that can cure everything from poor immune function, thyroid disease, and heart disease, to obesity, cancer, and HIV.
So should you stock up on coconut oil? Not so fast.
The evidence that coconut oil is super-healthful is not convincing and these claims appear to be more testimonials than clinical evidence.
There is very limited evidence on disease outcomes, says Dariush Mozaffarian, MD, DrPH, of Harvard Medical School and Harvard School of Public Health. "All that has been studied well is the impact of coconut oil on cholesterol levels and the findings are intriguing but we still don't know if it is harmful or beneficial," Mozaffarian says.
Neither the American Heart Association (AHA) nor the U.S. government's 2010 Dietary Guidelines suggest that coconut oil is any better or preferable over other saturated fats. Coconut oil, like all saturated fats, should be limited to 7%-10% of calories because it can increase risk for heart disease, according to the AHA and 2010 Dietary Guidelines.
