Is there somone on this list who could kindly tell me what is the
spanish translation for the english sentence "I am allergic to dairy
products, including milk, butter, cheese, and whey powder."

I have asked a Spaniard for the same information, but he was totally
bemused by my request for a translation. He claimed that Spaniards
would not understand even if the sentence was translated accurately.

TIA
