I think the raw oils are not that bad (maybe in quantity it becomes an issue). Coconut oil I know is saturated fat, so that can be bad for your heart.
I think the bigger issue is how they are used in processed food. Just about every processed food has “partially hydrogenated soybean oil” or something like that, which is basically the worst possible thing for cholesterol.
It’s the same with how everyone started using Crisco because lard was thought to be unhealthy. It turns out heavily processed vegetable oils are worse.
They’re measuring how many people can pass through a fixed point in space in an hour, not how long it takes one person to get from point A to point B.
So not really time or energy, but quantity.
