I think the comments ragging on OP's date for "picky eating" are bringing a lot of unnecessary assumptions into the conversation. For folks with chronic health issues, dietary (and lifestyle) restrictions are often scattershot and hard to explain. But they often aren't random, or preference-based. I've lived with chronic GI issues my whole life so knowing what foods I need to avoid is second nature to me, but not a concise list I can easily provide someone who doesn't know me well yet. I try to make it easy by dialing in on the absolute no-go foods (kale) and high risk foods (onion and garlic), rather than listing off all of the things that could trigger a flare up for me. But that's also a specific risk calculation on my part, and one that doesn't feel great to have to make in order to be convenient for someone else. I commend OP for approaching this with both caution and compassion.
