What is a good diet for desert iguanas and any tips on taming?

Iguanas are herbivores. They eat greens, vegetables, squash, fruits, and grains. Foods such as spinach, beets, swiss chard, dock, sorrel, whole grains, celery, kale, and carrot tops should be avoided as they have a tendency to bind calcium. Hand feeding them is a good way to tame them.
