How many cups are too much to drink a day?

How many cups are too much to drink a day?

The study, based on UK Biobank data of 347,077 participants aged between 37 and 73 years old, was a bid to understand if some of us are more resilient to coffee's effects than others.

Another recent study, carried out at the University of South Australia, sought to investigate how much coffee is too much - and found the results to be surprisingly high.

In Australia, one in six people are affected by cardiovascular disease.

As per the World Health Organization (WHO), cardiovascular disease is the main cause of death, yet a standout amongst the most preventable. "In order to maintain a healthy heart and healthy blood pressure, people must limit their coffees to fewer...cups a day".

This isn't the first time we've been celebrating a potential link between coffee consumption and life expectancy.

"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?'", Prof Hyppönen says.

"We also know that risk of cardiovascular disease increases with high blood pressure, a known outcome of excess caffeine consumption", she said. Six or more cups, they say, increases heart disease risk by up to 22 percent.

The study's authors analyzed dietary patterns and health records of almost 350,000 participants between ages 37 and 73.

In other words drinking coffee can play a role in helping people to live longer.

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?

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.

This team looked at genetic variations at "AHR, CYP1A2, CYP2A6, and POR" genes. They also found that their conclusions were independent of genetics-meaning those who are highly sensitive to the effects of caffeine were just as likely to develop heart disease over the six-cup limit as those who can drink a triple espresso without getting jittery.

The chemical acrylamide, which is found in coffee as a byproduct of the brewing process, has also been linked to cancer (it's most likely not unsafe in the amounts found in coffee, though).

These findings held true regardless of the participants' ages, sex, smoking status, weight, or the amount of caffeine in the coffee they drank.
