Idk, some fruits are pretty useless or simply weak - you might as well wanna keep your ability to swim instead. But in One Piece, even if you get the long-nose fruit, which would allow you to increase the size and length of your nose, some random powerful pirate would use that fruit to turn his/her nose into a spear + haki and become a lethal sword fighter. The boogers of that person would be poisonous and so on, coating the nose blade. That's One Piece, the only limit is your imagination.
My suggestion is for loam to wait instead of eating the fruit immediately. Lets first get a DF encyclopedia first to see what fruit it is. Plus who knows maybe they will manage to find another fruit. Also who says that loam is the one to eat it? What if sanji thinks that it is the invisibility fruit? Or if the fruit gives powers over plants? Then usopp would be better suited to eat it. There is also nami that is an option plus her greed for money and any DF is worth a lot.
