There appears to be a fairly reasonable dose-response relationship, with a modest increase in risk for ANY coffee drinking That being said, it's probably a minuscule increase in risk for low intakes (<2 coffees a day), which is where the recommendations come from
(For reference, a single cup of coffee is usually around 100mg of caffeine)pic.twitter.com/D18HZgUIqa
So, the new study probably isn't going to change established evidence, especially given that it's fairly small But - it's new, it's interesting, it is absolutely justifiable to report And here's our conflict
Science moves forwards in tiny steps If we see another half dozen carefully thought-out studies like this one published, it might change the recommendations
Conversely, the news is always new by definition It's not interesting to hear that we are years away from changing much, so the reports are always going to sensationalize what is fairly humdrum to most scientists
