What are the functions of walnut oil, coconut oil, camellia oil and olive oil respectively?

Except coconut oil, other vegetable oils are unsaturated fatty oils, which are easy to oxidize, and are long-chain fatty acids, while coconut oil is saturated oil, a rare medium-chain fatty acid in the world, which is rich in lauric acid only found in breast milk, so coconut oil is antioxidant, and the effects of other vegetable oils are easy to achieve, so don't worry about how much you eat! I hope I can help you.
