Exactly right. Not all plant-based oils are good for you. Just use extra virgin olive oil. I read that imported olive oils may contain some doubtful oil, so I buy California Olive Ranch oil. It comes in a glass bottle, which is important too.
As for butter, I vaguely remember what that is, haven’t touched it in decades, it’s saturated artery-clogging fat.
Say what you will about California, but in this regard, they are quite strict about whether olive oil produced in California is exactly what it is claimed to be. The California Olive Oil Council and the Olive Oil Commission of California make sure of this. Don't be fooled by fancy labels on imported olive oil, there is no guarantee that what's inside is the real deal.
Congratulations, you’ve been properly brainwashed concerning butter!
Just the way I like it too. The butter I had in Europe was soo good, you ate it like a cheese spread.
