Common Name: Kale (Curly Kale, Collard Greens, Spring Greens)
Latin Name:Brassica oleracea (Acephala Group)
Family Name: Brassicaceae
Kale has a high calcium content and only half the oxalic acid of dandelions, making it a potentially nutritious food.
Unfortunately, like all the brassicas, it is also high in goitrogens (which interfere with iodine uptake, resulting in thyroid problems). However, Kale also has a high iodine content, which lessens the goitrogen effect and it is therefore acceptable to feed to your tortoise in moderation, especially in winter with non-hibernating tortoises, when fresh weeds are scarce. See Cabbage.
