What they established was that drinking water damages DNA. When they drank coffee there wasn't as much damage. It's a stretch to say that coffee is providing a protective effect though.
Without denigrating anyone, it's a bad study.
What was the chemical breakdown of the water? Was it tap water? Distilled? Bottled? Spring? etc.
A better designed study would have groups drinking different kinds of water. Was the fact that the water was boiled (in the coffee) providing the protective effect? i.e removing toxins etc, did the kettle they use have a filter that processed the water, whereas the water was drunk straight from a tap etc.
Coffee is great though!

- Retra 8y agoCoffee contains water. If water is harmful, coffee will be just as harmful unless it has protective effects. In any case, you can't say they "established that drinking water damages DNA" and then go on to argue that they should establish it with another study about water.
- cbhl 8y agoIt's not clear to me that the control group drank 500ml of boiled water. If they're drinking cold tap water, it could be that the act of boiling the water yields the desired effect. If they're drinking bottled water (and if the instructions said "drink 500ml of water", this would be my first inclination) then maybe the DNA damage is being caused by plastic that's leaching into the water as opposed to any preventative effect in coffee.
