Iguana bits is a consumable in Fallout 76.
Chunks of iguana meat inside a small can. Eating this meat restores a small amount of health and slightly irradiates its consumer. It can be cooked to provide additional benefits.
Because there are no iguanas in the game, iguana bits can only be found on the bodies of dead NPCs, bought from vendors, or found as world objects. They are frequently found in coolers.
