You may have heard about the plant compounds called phytochemicals in coffee; such basic elements remain whether coffee is caffeinated or not, and whether you use a $5,000 espresso machine or you pour some hot water onto some powder. A recent study has shown coffee could cut the risk of death even in those who struggle to metabolize caffeine, scientists believe.
From that huge sample size, the study found that coffee drinking had a pronounced inverse association with mortality, meaning fewer participants who regularly consumed coffee died during the study period.
Even people who said they drank more than eight cups a day were less likely to die, on average, than non-drinkers, the team, led by NCI's Erikka Lotfield, reported.
"For example, prior studies have suggested that variants in CYP1A2, (a gene) encoding the enzyme responsible for more than 95 percent of caffeine metabolism, may alter associations of coffee drinking with cardiovascular-related outcomes, with slower caffeine metabolizers having higher risk of developing hypertension (high blood pressure) or having a myocardial infarction (heart attack) relative to their non-drinking counterparts, whereas faster caffeine metabolizers who drink coffee are at no or lower risk of these outcomes".More news: Trump says he's interviewed four candidates for Supreme Court
