How many cups are too much to drink a day?

Their results showed that compared to those who drank just one to two cups of coffee daily, people who drank six or more were 22% more likely to develop cardiovascular disease during the study period.

"Coffee is the most commonly consumed stimulant in the world - it wakes us up, boosts our energy and helps us focus - but people are always asking 'How much caffeine is too much?'", said Elina Hypponen, a professor at the University of South Australia.

The study authors believe that coffee (in large quantities) and heart problems may be linked because excess caffeine consumption can cause high blood pressure, a risk factor for cardiovascular disease.

Previous studies have found multiple other benefits of drinking coffee, including reducing the risk of Alzheimer's and Parkinson's disease. And if you're not a coffee drinker, maybe you might want to give your first sip another try.

It's also a major cause of death with one person dying from the disease every 12 minutes in that country.

Speaking to The Sunday Times, Astrid Nehlig, a research director at France's National Institute of Health, said: "It is hard to calculate, but my feeling is that drinking coffee possibly adds another couple of years to your life".

Using UK Biobank data of 347,077 participants aged 37-73 years, the study explored the ability of the caffeine-metabolising gene (CYP1A2) to better process caffeine.

Researchers found that people who drank two and a half cups of coffee daily had a 17% lower risk of death from cardiovascular disease.

In two new research papers, experts tackle the ideal amount of coffee to drink every day: two to four cups to improve life expectancy, but no more than five cups to avoid the adverse effects.

She then suggested that people can maintain a healthy heart and a healthy blood pressure if they limit their coffee to fewer than six cups a day. People with this gene could metabolize coffee faster than others.

And they identified which coffee consumption habits increased or lowered the risk of cardiovascular disease.

While coffee can be good for you and even help to get you going in the mornings and keep you going in the afternoons, is there a point where too much coffee can harm your health? Irrespective of the cause, nutritional concerns need to be addressed in this condition in order to prevent morbidity and mortality.

There are many conflicting health reports out there when it comes to coffee, but according to latest research, a moderate daily dose of caffeine can actually increase your life expectancy.
