There seems to be some debate regarding this, though it is commonly accepted that this was merely a rumor that began with his increasingly erratic behavior in the late seventies and popularized by the movie "Rise and Fall of Idi Amin". Try:

(Lots of links at the bottom of the page)
or

(from the above article)
"Popular legend has Amin involved in Kakwa blood rituals and cannibalism. More authoritative sources suggest that he may have suffered from hypomania, a form of manic depression which is characterised by irrational behaviour and emotional outbursts."
Hope this helps!
