Three Coffees a Day Brings More Health than Harm, According to Study

In a linked editorial, Eliseo Guallar at the Johns Hopkins Bloomberg School of Public Health, said although we can be reassured that coffee intake is generally safe, doctors should not recommend drinking coffee to prevent disease - and people should not start drinking coffee for health reasons.

People who drink three to four cups of coffee a day are more likely to see health benefits than harm, experiencing lower risks of premature death and heart disease than those who abstain, scientists said on Wednesday.

At the same time, high consumption is associated with an increased risk of bone fractures in women, and can also lead to a higher risk of rheumatoid arthritis.

The research, which extracted evidences from over 200 past studies on the matter, also discovered that drinking coffee was linked to lower risks of diabetes, liver disease, some cancers, and even dementia.

Apparently, three to four cups of coffee a day is the optimum amount, according to the researchers.

The protection was greatest for liver and bowel tumours.

To better understand the effects of coffee consumption on health, a team led by Robin Poole, from the University of Southampton in the United Kingdom, carried out an umbrella review of 201 studies.

Experts said it is impossible to know whether the health lift it due to the coffee or other habits that are more common amongst drinkers.

Experts said it is the largest ever study looking at coffee consumption and health. Of those studies, only 17 were clinical trials, and the rest were observational research. There was less evidence for the effects of drinking decaffeinated coffee but it had similar benefits for a number of outcomes.

But it's not all doom and gloom for coffee lovers. Increasing consumption to above three cups a day was not associated with harm, but the beneficial effect was less pronounced.

Roasting coffee beans and drinking the ground results dates back to the 15th century, a practice that has become increasingly popular in modern Ireland but that often raises concerns for potential health implications. Women seem to benefit more than men with higher levels of consumption if factors like mortality from cardiovascular and coronary heart diseases are considered. However, when too much caffeine is consumed, it may take a toll on the body.
