The August 27, 2017, issue of Science Daily reported that higher coffee consumption is associated with a lower risk of death. This was based on an observational study of nearly 20,000 participants. Researchers found that participants who consumed at least 4 cups of coffee per day had a 64% lower risk of mortality than those who never or almost never consumed coffee. Does this mean that a person can reduce his or her chance of death by increasing the amount of coffee consumed?
