How to say "I have a a peanut and walnut allergy, even with just the oil. If I eat it I could die." My friend and I will be travelling to Korea this summer. My friend however, has a severe walnut/peanut allergy and I want to put this phrase on a piece of paper so we can show it to people. I'm also aware that nut allergies aren't very common in Korea so they might not take it seriously. Peanut allergies are responsible for more than half of food allergy related deaths, which is common knowledge in Europe but not in Korea. So how do I say: "I have a a peanut and walnut allergy, even with just the oil. If I eat it I could die." You don't have to translate literally, just say it however way you think makes it very clear.
