Dr Malik often tells patients with palpitations and even blackouts that coffee and tea may be the cause. Stopping it may avoid more investigations and invasive treatments. But here is a tale from a very worthy journal suggesting that high coffee intake may be linked to reduced mortality. It was not a randomised trial and so it is by no means certain that these high coffee drinkers were not different in other ways from the non-coffee drinkers, but the study did try to control for smoking habits, social class, body mass index etc.
Message: if you like coffee and are not getting dose effects, then keep on going. There seems no need to cut back on this ubiquitous and legal “high”.
