Death by Vegetable Oil: What the Studies Say

they experienced a rate of metastasis (spread of cancer) four times higher than mice fed the fats found in olive and avocado oil

That's interesting. They are all "vegetable" sources, but all the others are essentially seed oils. Olive oil and avo oil come from the fleshy part of the fruit, not from the pit/seed. It had never occurred to me to lump oils together that way. I wonder how that holds up with other oils (e.g. coconut oil).

At the same time, he throws out things that a researcher would feel very uncomfortable saying, such as:

Tying these two mouse studies together: if deep fried vegetable oil causes four times as much cancer growth as unheated vegetable oil, and if unheated vegetable oil causes four times as much cancer growth as unheated olive oil, then deep fried vegetable oil may be sixteen times more carcinogenic than unheated olive oil.

It's far from a given that the effects compound in a simple manner like that. It may be 32 times worse or 8 times worse. And I may be president of the United States in 2025. Probably not, but we won't know until the data is in.

Same with this:

Sadly, most restaurants don't use traditional cooking fats like coconut oil and ghee because they are too expensive.

None of the studies speak to the positive or ill effects of coconut oil. That's going beyond the data.
