Researchers claim drinking three to four cups of coffee a day may lower the risk of death and developing heart disease as compared to non-drinkers. <br/><br/>They said coffee drinking is also associated with lower risk of some cancers, diabetes, liver disease and dementia. <br/><br/>A review of over 200 studies published in The BMJ today journal found that coffee is more likely to benefit health than harm it. <br/><br/>Researchers said drinking three to four cups of coffee a day is associated with a lower risk of death and getting heart disease compared with drinking no coffee. <br/><br/>However, they said that drinking coffee in pregnancy may be associated with harms, and may be linked to a very small increased risk of fracture in women. <br/><br/>To better understand the effects of coffee consumption on health, a team led by Robin Poole, from the University of Southampton in the UK, carried out an umbrella review of 201 studies. <br/><br/>Researchers said drinking coffee was consistently associated with a lower risk of death from all causes and from heart disease, with the largest reduction in relative risk of death at three cups a day, compared with non-coffee drinkers. <br/>
