I have a Doctor friend who says exactly the opposite. C oil is fantastic and it’s Canola (Rapeseed) Corn, Palm, and Soybean oils that should be avoided.
My Dr is not anybody special, certainly correctable. She tells me to go with Canola, olive and avoid all tropical oils especially palm.
But I will ask her about coconut oil (unsaturated for sure)
She also told me that if anything I eat tastes good, I am to spit it out :)
