Three Coffees a Day Brings More Health than Harm

The good news is that overall, coffee consumption was determined to be "generally safe within usual levels of intake" - but if you're you want to get even more specific, the sweet spot was three to four cups a day.

Now, scientists say coffee is more likely to help than harm you. And this study is significant because while lower risks of liver disease, cancer, and stroke had been posited in the past, researchers had not been able to pinpoint coffee as the cause.

But before we can start giving coffee to patients, we needed to know whether coffee drinking had any recognised harms, so we chose to conduct an umbrella review to capture as much important information about coffee drinking and health as we could.

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

Until recently people were warned against drinking more than a few cups of coffee a day, for fear that it might cause cancer.

This is not the first discovery of coffee's positive benefits.

Moderate coffee drinking is protected, and three to four mugs a day may have some medical advantages, as indicated by an expansive audit of past examinations, in the BMJ.

So, the authors urge that "robust randomized controlled trials are needed to understand whether the observed associations are causal".

The study conducted by researchers led by Robin Poole, a specialist registrar in public health at the University of Southampton in the United Kingdom, noticed greatest risk reduction for liver cirrhosis.

Increasing consumption to above that amount was not associated with harm, but the beneficial effects were less pronounced. There were also lower rates of type 2 diabetes, gallstones and dementia associated with coffee consumption. "We simply do not know", Guallar wrote, continuing, "Coffee drinking is a complex behavior determined by cultural norms and associated with multiple socioeconomic, lifestyle, dietary, and health behaviors".

Since the review was an analysis of existing studies, it is impossible to account for many other factors that might have influenced the subjects' health.
