Q. Can you eat leeks if you are allergic to onion?
A. Leeks come from the same family (allium) as onions, but so does garlic and chives. If you can handle garlic, then possibly leeks would be fine. However, allergies can be very serious. Every person reacts differently, so to be safe talk with your doctor or an allergist to see if you would be safe adding them to your diet.
