So how much do I need to worry about the foods that are high in goitrogens and oxalates? Mustard greens are listed as a staple green but states that they are high in Calcium, but also contains goitrogens. What does this tell me?
The iguanas diet should contain 2 times as much calcium as phosphorus. That means the overall diet, not the individual items.
As long as you are feeding a variety of foods, there aren't enough goitrogens in mustard to cause a problem. For instance, broccoli and cauliflower are both high in goitrogens as well, so it would probably be best to avoid using them with mustard.
