Anything in excess is bad, even water can kill you if you drink too much of it, green leafy plants can also poison you if you eat too many of them in one sitting as well.

I am very sceptical of this professor or any professor publicly decrying a food product, because we all know big pharma love to donate to schools like Harvard and in return they get to manipulate research and further their agenda.

As always, I am sure if you follow the money you'll yield some interesting transactions that can be correlated to this "research" about coconut oil.
