How Much Coffee Is Too Much? A New Study Has the Answer

For many people, the start of a day is usually kicked off with a cup of coffee, providing much needed fuel for the day.

"We also know that risk of cardiovascular disease increases with high blood pressure, a known effect of excess caffeine consumption", she said.

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.

You may want to stop preparing that next cup of coffee.

According to the World Health Organization (WHO), cardiovascular disease is the leading cause of death, yet one of the most preventable.

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

Having set out to uncover the relation between long-term coffee consumption and heart disease and to explore the potentials of the caffeine-metabolizing gene, the researchers made quite interesting findings.

In order to maintain a healthy heart and a healthy blood pressure, people must limit their coffees to fewer than six cups a day, researchers said.

Presumably the PM and ministers have noticed that mortgaging the UK's Brexit future to Jeremy Corbyn is haemorrhaging the Tory vote.

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

Moderate coffee consumption, which could range between two and five cups per day, "was associated with reduced all-cause and cause-specific mortality, compared to no coffee consumption".

The team used data from the UK Biobank including 347,077 participants aged 37-73 years.

Fortunately for us, numerous studies have revealed that coffee can be good for our health in many ways - at least potentially helping to protect us from multiple sclerosis, Parkinson's disease, type 2 diabetes, cirrhosis of the liver, and Alzheimer's disease, among other afflictions.

If you're someone who can't function in the morning without your daily boost of caffeine and you simply can't help but to reach for an aromatic cup of roasted coffee around 3pm, here's something you might want to know. 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.

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

Their results showed that "Coffee drinking was inversely associated with mortality, including among those drinking 8 or more cups per day and those with genetic polymorphisms".
