Evangelist Franklin Graham has converted to one of the last things his largely conservative following would have imagined: a modern American vegan.

The son of Billy Graham announced to his 747,000 Twitter followers that he is adopting a vegan diet in the new year, which means he will not eat animal products. This includes no butter, eggs and milk.

Graham is taking the vow seriously enough to post daily images of his vegan meals on Twitter. (@Franklin_Graham)
