Scientists sure are a contentious lot. First we wouldn't stop getting stories about how awesome coffee was in terms of health, and now the opposite:
In March, a study that followed more than 3,000 coffee drinkers in Greece for two years found troubling levels of inflammatory substances in their blood, compared with the blood of those who don't drink coffee.
In other studies, those substances have been associated with higher rates of heart attack and stroke, although the new study did not assess whether the coffee drinkers were at more risk.
The study, which was presented at the American College of Cardiology annual meeting, found that men who consumed more than a cup of coffee a day had 30 percent higher levels of a particular inflammatory substance in their blood, compared with non-coffee drinkers. For women, it was 38 percent higher.
