Are you or do you know a person who is allergic to seafood?

My sister is allergic to seafood, but I think she is very strong. She eats everything she likes. To be honest, I'm worried about her health.

I have my sister. She is allergic to seafood, but I think she is quite strong, too. She never worries about her allergy to food. She just eats everything she likes. To be honest, I am pretty worried about her health.

Actually, I don't know about people who have allergies to seafood, and I am not allergic to seafood, but I think those people who have that health issue struggle with their lives because it's hard to avoid it in your life.
