Cambridge (IINA) - Scientists from Harvard School of Public Health (HSoPH) said in a recent study that drinking up to five cups of coffee a day could help people live longer, Mail Online news reported.
The risk of an early death from heart disease,Parkinson’s disease and type two diabetes are reduced by moderate coffee drinking, their research suggests.
The study, based on more than 200,000 people, suggests that drinking coffee also lowers the risk of suicide. Whether or not the coffee drunk contained caffeine made no difference. The benefits are thought to be linked to plant compounds in coffee beans.
Lead scientist Ming Ding, of Harvard School of Public Health (HSoPH) in the US, said: ‘Bioactive compounds in coffee reduce insulin resistance and systematic inflammation.
The authors found that drinking between three and five cups of coffee a day has beneficial health impacts.
‘That could explain some of our findings. However, more studies are needed to investigate the biological mechanisms producing these effects.’
The results, published in the journal Circulation, were based on a pooled analysis of three large on-going studies with a total of 208,501 male and female participants.
Coffee drinking was assessed using food questionnaires completed every four years for around 30 years. Compared with less or no coffee drinking, moderate coffee consumption was associated with a significant reduced risk of death across a range of causes.
The analysis took into account other factors that could have influenced the results including smoking, body mass index, levels of physical activity, alcohol consumption and diet.
"This study provides further evidence that moderate consumption of coffee may confer health benefits in terms of reducing premature death due to several diseases," Co-author Professor Frank Hu, also of HSoPH, said.
But Emily Reeve, senior cardiac nurse at the British Heart Foundation, said: "It is important to remember that maintaining a healthy lifestyle is what really matters if you want to keep your heart healthy, not how much coffee you drink."
Previous research suggests that drinking up to five cups of coffee a day is not harmful to people's cardiovascular health, and this study supports that. But more research is needed to fully understand how coffee affects our body and what it is in coffee that may affect a person’s risk of heart attack or stroke.
