Are iguanas carnivores

As adolescence iguanas will eat insects and other meat proteins, however these proteins are hard for the iguana to digest as it gets older. They should be fed primary an assortment dark leafy green vegetables such as bac choy, and romaine lettus.
I'll use the Green Iguana as my example. Babies are primarily insectivores, eating some vegetable matter. Adults are nearly completely herbivores.
