Qabisah bin Hulb narrates from his father (Sayyiduna Hulb (may Allah be pleased with him)) that he said: I heard the Messenger of Allah (peace and blessings be upon him) when a man asked him: "There are some foods that I feel uneasy about." He (peace and blessings be upon him) said: "Let nothing cause unease in your heart in which you would be resembling Christianity."
