I give them celery sticks maybe twice a week 1/2 stick per head, but never actually fed them radishes or beans, if she gets sick after I would just stop feeding her them.
I give them a small piece of a carrot maybe once a week, 1/4 or 1/8 of an apple without seeds like once a week, or some other fruit, small piece of a plum etc, but that's for treats. On a daily basis I use cauliflower leaves or herbs, cilantro/coriander, dill, fennel, mint, thyme, sometimes kale but only once a week or 1/2 or 1/3 of cabbage leaf also rarely if I don't have other greens at hand.
What else she eats, hay, what pellets, or you just feed fresh food?
