So no, there's no reason to completely cut out coffee, but it is smart to pay attention to how much you're really drinking.

Drinking as little as two cups of coffee a day could increase your life expectancy by up to two years, new research has revealed.

The study analysed previous studies on benefits of drinking coffee by looking at 40 studies that included around 3,852,651 participants of which there were 450,256deaths.

These findings held true regardless of the participants' ages, sex, smoking status, weight, or the amount of caffeine in the coffee they drank. One small study found that regular coffee drinkers were 16% less likely to develop Alzheimer's, and another study of over 50,000 women found drinking at least one cup of Joe each week was associated with a 15% reduced risk for depression.

"As aging, obesity and lifestyle factors affect the risk of mortality, the association between coffee and mortality needs to be examined in various sub-populations by characteristics of subjects", the study explains.
Furthermore, the study also found that lowered mortality in connection with coffee consumption was more prevalent in Asia and Europe than in the US.

Five of the top eight drivers in qualifying will move to the back of the pack after failing pre-race/post-qualifying inspection. That means Almirola, who qualified second, and Suarez, who was fourth, will have to start behind all those who passed.

Other past research backs up the most recent findings about coffee and decreased risk of disease. The new study was published this month in the journal American Journal of Clinical Nutrition and was titled, "Long-term coffee consumption, caffeine metabolism genetics, and risk of cardiovascular disease: a prospective analysis of up to 347,077 individuals and 8,368 cases".

Coffee drinking was also associated with a lower risk of some cancers, diabetes, liver disease and dementia. In fact, the researchers also found that participants who didn't drink coffee at all-and those who drank decaf-also had higher rates of heart disease (11% and 7% higher, respectively) than those who drank one to two cups per day. The present study set out to determine just how many cups people could drink to get benefits without negatively affecting their cardiovascular health.

These conclusions have led the researchers to believe that consuming a large quantity of coffee is linked to heart issues because of high blood pressure, which is a side effect of overdosing on caffeine. "Knowing the limits of what's good for you and what's not is imperative", Hyppönen said in the press release.

A similar study on genetic variation and effects of coffee was published a year ago August by authors E Loftfield and colleagues in the journal JAMA Internal Medicine titled, "Association of Coffee Drinking With Mortality by Genetic Variation in Caffeine Metabolism: Findings From the UK Biobank".
