Here is nice meta study of coffee and cancer risk (dna damage and cancer are probably linked). https://www.nature.com/articles/srep33711 > coffee intake was associated with reduced risk of oral, pharynx, liver, colon, prostate, endometrial cancer and melanoma and increased lung cancer risk.

To your parenthetical comment: May be unrelated, but totally anecdotal, smokers tend to drink a very light roast that is easily drinkable like a folgers or maxwell house, maybe a coffee shop light roast, like a Dunkin. I don't think smokers are downing cups of Starbucks dark blend and if they are god help their stomachs.

Dark roasts are easier on the stomach than light roasts as the roasting process reduces the acidity of the resultant brew.

Coffee 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.

It'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…

Lighter roasts have more caffeine, because the roasting process damages the caffeine molecule.

"Funding This study has been supported by Tchibo GmbH, Hamburg, Germany." Tchibo is a German chain of coffee retailers and cafés known for its range of non-coffee products that change weekly. https://en.wikipedia.org/wiki/Tchibo Number of locations 700 shops (Germany) 300 (rest of world) They might want to make some in-store claims about Dark Roast...

I'm generally sceptical of all studies about coffee for this very reason. There's a lot of bullshit studies around food and supplements funded with people with strongly vested interests in selling more product. It's a real problem. For any given supplement, you can often find multiple studies supporting its use and multiple studies saying it's harmful. When it comes to coffee specifically, if you listen to the studie…

> There's been a study claiming that caffeine decreases neurogenesis, which should negatively impact both long-term memory and mood.

How much caffeine was required for this effect and how long did it last?

Coffee remains one of the few things you can buy the best of, in the world, for less than $100usd and enjoy for several days.

Only grind what you are going to brew immediately. Use a conical Burr grinder. Technivorm coffee machine else bonavida.

I'm surprised (horrified?) that a control group's DNA deteriorates significantly enough in such a short trial to use as a comparison. #entropy

The study is likely useless since eight weeks total does not constitute long-term effects. You’d need to do this with a larger sample size over years to get reliable data.

If it's the plastic, then we need follow up studies comparing people drinking coffee in plastic cup vs paper cups vs other non plastic non paper glassware!

I don’t think it’s the cup that leeches plastic, unless it contains BPA.
