This is how many cups of coffee you should be drinking

"If you drink a lot of coffee, you might feel jittery, irritable or even nauseous".

Elina Hypponen said that coffee is one of the most commonly consumed substances that helps to boost energy, wakes us up, and also helps to focuses on work.

That's because too much caffeine can cause high blood pressure, a precursor to heart disease, researchers say. Now, the latest research shows that drinking at least two cups of coffee per day can increase the life expectancy of consumers by up to around two years.

The study utilized the data of 347,077 individuals aged 37-73 years old, investigating the caffeine-processing ability of the caffeine-metabolizing gene, CYP1A2, and identifying the increased risks of cardiovascular disease in line with coffee consumption and genetic variations.

"It is hard to calculate, but my feeling is that drinking coffee possibly adds another couple of years to your life", said Astrid Nehlig of France's National Institute of Health and Medical Research in Sunday Times, explaining that part of the reason could be improved focus that a cup of brew brings.

In a meta-analysis published May 4 in European Journal of Epidemiology, researchers looked at over 3 million people from 40 previous studies and found that those who drank two or more cups of coffee daily had decreased risks of death.

Researchers discovered that keeping coffee consumption under six cups per day was unlikely to affect heart health.

The American Civil Liberties Union of Alabama said a complaint is being drafted to challenge the ban. The text of the bill likens abortion to history's greatest atrocities, including the Holocaust.


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

"An estimated three billion cups of coffee are enjoyed every day around the world", concluded Hypponen.

Coffee consumption was also associated with reducing the risk of both developing and dying from cancer, cardiovascular disease, diabetes and respiratory disease, as well as increasing life expectancy.

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.

"Knowing the limits of what's good for you and what's not is imperative", she said.

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).

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