Some liver cleanses out there call for olive oil mixed with fruit juice in order to trigger your liver to expunge its gallstones. But aside from that olive oil should be your go-to oil for use in cooking when you’re trying to detox the body. That’s because it has a lot of healthy properties, and makes for a better choice of fat than most of your other options.
Just be sure not to cook with it at high heat. Use it as a salad dress to help things like dark leafy greens go down.
