New research studies association of coffee consumption and heart diseaseDrinking six or more cups of coffee a day can be harmful to your health, increasing the risk of heart disease by up to 22 per cent, a study claims.
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.
Can't get through the day without a couple of cups of joe?
"Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseous", said co-author Elina Hyppönen, director of the Australian Centre for Precision Health, in a press release.
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).
"Knowing the limits of what's good for you and what's not is imperative", she said.
In this research, scientists analysed 40 previous studies exploring the link between coffee and mortality, including a total of 3,852,651 participants and 450,256 causes of death.
The researchers analyzed previous studies from around the world that included information about people's coffee drinking habits and their causes of death, including cancer, cardiovascular disease, and diabetes.
"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.
According to sciencedaily.com this was much needed research down under because in Australia, one in six people are affected by cardiovascular disease. That might not be such a bad thing according to a new meta-analysis, which suggests that drinking just two cups of coffee a day could increase life expectancy by up to two years.
On analysing the results researchers discovered that coffee consumption had an inverse association with all-cause mortality, "irrespective of age, overweight status, alcohol drinking, smoking status, and caffeine content of coffee".
The research team used UK Biobank data of 346,077 individuals aged 37 to 73 years. They found also found that despite the ability of the caffeine-metabolizing gene CYP1A2 to process caffeine better and more quickly, it doesn't mean that individuals who carry this gene can consume more coffee without detrimental effects.
