Interesting question. I checked the New Crops website of Purdue university to see if one of their resources addressed this, and none did. You can eat the luffa gourd when much less mature. About all the comments center on eating it when tender, or processing it when mature, but nothing about the sap or flesh that one is removing. Here is the link for the New Crops web site if you want to explore a little on your own. Wikipedia has a nice section on it as well.
