Lucy, quoting from the article you linked to:
“One problem is that some researchers might use methodology that is not the best or most current for evaluating effects of dietary fats.”
Agreed. And then right in that same article it says, “In fact, the science says that coconut oil, which has mostly saturated fatty acids, raises your LDL cholesterol, which is linked with increased risk for heart disease.”
The problem here is that that is woefully incomplete, and often simply not true. There is more than one type of LDL cholesterol - there are different particle sizes of it, and that makes a vast difference. To state, in an unqualified manner, that in effect “LDL cholesterol is really bad for you - it raises your risk of heart disease” - no, this very often not true. There is a lot more to it than that.
It’s a great topic - lots for us all to learn, and hopefully - eventually - the medical community will get better at recognizing what all is going on, rather than engaging in excessive over-simplification.
