So I know Passover is a ways away but I have a question about it. I recently got diagnosed with celiac and Ulcerative colitis and what i can and cant eat is already very restricted as I'm vegetarian as well. Is it alright for me to keep eating beans, corn, and rice? Sorry if this doesnt make sense. I just have to keep my diet pretty much the same to help my condition stay stable and not flair up. Thank you so much!!
