British censorship?

The Wikipedia article about this movie includes this: "When the British release (with cuts imposed by the British censors[16]) took place in late 1956..." This is amazing. I've seen this movie several times (it's one of my favorites), and I can't think of a single scene or a single word that might've offended the British censors. I realize that things were different in those days. The studio tried to get Hitchcock to cut the "Psycho" scene in which something is flushed down a toilet! But "Body Snatchers" has no toilets, no sex, no nudity, no language, and virtually no violence -- what in the world were the British censors cutting out? Does anyone have a clue?
