How much coffee is too much?

How much coffee is too much?

The conflicting findings of existing coffee studies mean more research needs to be done, but in the meantime you shouldn't sweat your coffee habit or, if you can't stand the stuff, try to incorporate it into your morning routine.

"An estimated three billion cups of coffee are enjoyed every day around the world", Prof Hyppönen says.

Researchers from the University of South Australia analyzed the health records and self-reported dietary patterns of 347,077 participants between the ages of 37 and 73.

Authors write that coffee has been connected to a reduced risk of prostate cancer, Alzheimer's disease and Parkinson's disease.

And it's good news if you are something of a caffeine fiend, as two cups per day could actually be helping you to live longer, according to new research.

That's because too much caffeine can cause high blood pressure, a precursor to heart disease, researchers say.

Overall, the researchers found that people who said drank six or more cups of coffee a day were 22% more likely to develop cardiovascular disease during the study period, compared to those who drank one to two cups daily.

He found that coffee could increase your heart attack risk by 50 percent - if you consume 2 million cups.

Similarly, a study from the U.S. found that participants who consumed a cup of coffee per day were 12 per cent less likely to die compared to those who didn't drink coffee. "Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseous - that's because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being".

"As with many things, it's all about moderation; overindulge and your health will pay for it".

The researchers identified increased risks of cardiovascular disease in line with coffee consumption and genetic variations. Over 10 years of follow-up they noted 14,225 deaths.

The study also found that the link between coffee and mortality was stronger in Europe and Asia than in the US.

The examination of the health benefits of coffee is one that has been widely assessed, with a similar study by Imperial College London and the International Agency for Research on Cancer finding that participants with the highest consumption of coffee had a lower risk of all-causes of death. They added that it could be due to the "additives or artificial colors in tea consumed in Iran, and candies or sugar that mostly consumed accompanied by tea".
