"The Church of Jesus Christ of Latter-day Saints has clarified its position on caffeinated soft drinks, noting the news media often incorrectly states that its members are forbidden to drink caffeine.

This week the church posted a statement on its website saying it 'does not prohibit the use of caffeine.'

A day later, the website wording was changed, saying only that 'the church revelation spelling out health practices ... does not mention the use of caffeine.'"
