What's the likelyhood of being allergic to morning glory seeds if i'm allergic to nuts?

Very low: I have never seen this as a problem but from what i could tell it is not in a similar species..Peanut is a legume arachis, but depending on how severe your peanut allergy is... To be cautious you might want to check with your dr..Maybe bring some to their office for a "live" scratch test and try it while in an exam room.

Testing: I agree that testing is indicated to determine whether this is safe. Very often patients with food allergies have allergies to other foods as well. Please make sure that you have an Epi Pen at home and with you.

HIghly unlikely: Even if one is allergic to one nut, the probability of becoming allergic to another nut is higher than people in the general population but still in low percentage. Even then, some of the reactions may have been from contamination with the nut implicated. Thus the risk of being allergic to morning glory seed is likely extremely low and unrelated to the nut allergy itself.
