Palm isn't bad but there are far better for both your body and the environment. Olive and avocado are about the two best that come from plants. Nut oils are okay as more a condiment then a full cooking oil. Seed oils especially any you can just simply press are all garbage. Corn, soy, canola may be about the absolute worst of the worst.

And if you live in a region where Pindo palm (aka wine palm, jelly palm) grows, which is a big part of the US, you can render a nice aromatic oil from the fruit kernel. It’s a lot of work though. But, stuff you have to work hard for is stuff you’re not likely to waste or overuse. Pindo oil smells like a combination of coconut and butter.
