Hello! I personally think that as long as the loofah skin is not too old and can be chewed, you can eat it without peeling it. The pharmacological and nutritional components of the loofah skin are very high. If you are focusing on dietary therapy, it is best to eat it with the skin on. Don’t add too much salt or too many condiments. It is best to boil luffa soup with water. The therapeutic effect will be better. I treat luffa as a dish. You can eat it with or without the skin. As long as you can bite it, it is best to eat it with the skin on.
