While humans have no nutritional requirement for caffeine (caffeine is not an essential part of the human diet), most adults can safely consume moderate amounts of caffeine. Wise, K.J. A meta-analysis of 22 studies found no clear connection between coffee consumption during pregnancy and preterm delivery 34).
