Coffee & Cancer – A Broken Link?
Back in 1991, an influential panel of cancer experts at the World Health Organization (WHO) declared the drinking of coffee as “possibly carcinogenic” and linked it with bladder cancer. The world didn’t heed this warning, however, and continued to drink the stimulating beverage. Today, over 130 million people in the United States are daily drinkers and globally, 1.6 billion cups are consumed per day. Should we be worried about a cancer boom?
Not so now says that same research group that drew the initial cancer link. In a recent meta-analysis conducted by 23 WHO researchers who poured over 1,000 clinical studies of the beverage, a definitive causality was not found. The experts in fact discovered that not only was drinking coffee unlikely to cause cancer, it was associated with a lower risk of uterine and liver cancers.
This recent paper underscores that scientific knowledge continues to advance. Data that supports one theory can be supplanted by stronger data supporting a contrary theory. But for us coffee lovers what it really means is that we can stop worrying about any health risks from coffee and enjoy our daily fix in peace.
