Drinking 3-4 cups of coffee may lower risk of death, heart disease
London: 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.
They said coffee drinking is also associated with lower risk of some cancers, diabetes, liver disease and dementia.
A review of over 200 studies published in The BMJ journal found that coffee is more likely to benefit health than harm it.
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.
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.
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.
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.
