This is the first multi-lingual allergy guide I have ever come across. The authors have done an excellent job. Though dialects may vary, and certain regions may have their own ways of describing a food, this is a very helpful little resource.
It is literally the size of a passport, and thus perfect for travel. It is English based with translations for French, German, Spanish, and Italian. The phrases address various situations (from conversing with waiters to describing symptoms to a doctor) and the food translations cover the “top eight” food allergens (milk, wheat, eggs, soy, fish, shellfish, peanuts, and tree nuts) plus gluten and corn. I highly recommend this phrase book for anyone who is traveling with food allergies, intolerances, or a special diet.
