Coffee consumption emerges as beneficial for public health

3-4 cups of coffee have more healthy benefits than harm: Study

Coffee drinkers were also found to experience lower risks of premature death and heart disease.

Guallar says doctors should not recommend drinking coffee to prevent disease and people should not start drinking coffee to improve health. Umbrella reviews combine previous meta-analyses and give a high level summary of research findings.

They wrote: 'Coffee is highly consumed worldwide and could have positive health benefits, especially in chronic liver disease.

Drinking coffee comes with a range of health benefits, a new study has revealed, giving caffeine junkies a valid reason to enjoy a guilt-free cup.

A new study finds drinking three to four cups of coffee a day won't just keep you awake, it may help you live longer.

"Factors such as age, whether people smoked or not and how much exercise they took could all have had an effect", he pointed out.

"We carried out this umbrella review to bring this existing evidence together and draw conclusions for the overall effects of coffee consumption on health".

Researchers applied machine learning, a process that uses artificial intelligence to track algorithms and patterns within data sets, to analyze the relationship between drinking coffee and cardiovascular health from across three well-known studies: the Framingham Heart Study, the Cardiovascular Heart Study and the Atherosclerosis Risk In Communities Study.

"There is a balance of risks in life, and the benefits of moderate consumption of coffee seem to outweigh the risks", said Roderick.

Though the group will soon begin their next phase to study the effect coffee has on the liver, Poole added coffee enthusiasts should still "try to make it as healthy as possible" and steer clear of the sugar.

More than three cups of coffee were linked to no harm but produced less enhanced benefits. There were also lower rates of type 2 diabetes, gallstones and dementia associated with coffee consumption.

The day hasn't really started until you've had your morning coffee.

Negative side of coffee drinking was found in women.

The researchers, therefore, added that they can not extrapolate their findings to suggest people start drinking coffee or increase their intake in attempts to become healthier.

Ultimately, the research lines up with recent reviews and studies that say drinking coffee doesn't seem to be hazardous.
