Three Coffees a Day Brings More Health than Harm


Coffee lovers, rejoice! According to a new study, you don't have to give up your favorite caffeinated drink to be healthy. The beneficial associations between consumption and liver conditions stand out as consistently having the highest magnitude compared with other outcomes across exposure categories.

The study conducted by researchers from the Universities of Edinburgh and Southampton and published on November 22 in The BMJ found that three to four cups of coffee every day is the optimum number, which was linked to a 17 percent decreased chance of death in comparison to non-coffee drinkers.

One of the major drawbacks to the research is that the study was a meta-review of scientific literature based on observations, meaning that researchers could only draw correlations instead of pointing out a clear cause and effect.

This is not the first discovery of coffee's positive benefits. Drinking coffee beyond these amounts was not associated with harm, but the benefits were less pronounced.

The findings also showed that coffee consumption was linked to lower risks of diabetes, liver disease and dementia.

The most grounded advantages of coffee utilization were seen in lessened dangers of liver disease, including growth.

Robin Poole, who led the research team, notes "Coffee drinking appears safe within usual patterns of consumption". This is not new knowledge, and there are guidelines for limiting caffeine intake in pregnancy.

Three or four cups a day confer the greatest benefit, the scientists said, except for women who are pregnant or who have a higher risk of suffering fractures.

Coffee drinking during pregnancy is linked with low birth weight.

"Coffee is known to cause headaches in some people and it also increases the urge to go to the toilet-some people chose not to drink coffee for these reasons", he said.

Although the review found that there was more benefit than harm from drinking coffee, the studies were not adjusted for important confounders, such as body mass index, smoking, age, alcohol use, income and education level. It's not about sugar, syrups, biscuits, cakes and pastries. Standard health messages still apply to those types of food.
