Broccoli is the only thing my tort will eat right now!! He was eating collard greens then decided he wasn't going to eat it anymore and didn't eat for a week... I live in rural WA and can only buy very limited store bought food and he gets a supplement.
Please understand that broccoli is a very healthy and nutrient-rich vegetable, however it is a cruciferous vegetable. Eating too much of it can suppress the function of the thyroid gland by interfering with iodine uptake, which can, as a result, cause an enlargement of the thyroid (goiter).
