A new study suggests the assumption that coffee can dehydrate the body just doesn't hold water.

British researchers tested 50 men in two groups. One group drank four cups of black coffee a day, while the other had four mugs of water.

Ten days later, each group swapped what they drank. Coffee drinkers switched to water and vice versa.

Scientists found that coffee hydrated the body as much as water.
