Every 5 years, the U.S. Department of Agriculture (USDA) and Department
of Health and Human Services (HHS) issues a new edition of the Dietary
Guidelines. These are dietary
recommendations for Americans to practice healthy eating habits.
Shaped by the Dietary Guidelines Advisory Committee (DGAC), these guidelines have an enormous impact on US perceptions and behaviors regarding nutrition and health, which is why it’s critical to communicate the science on coffee and health.
A massive meta-analysis suggests that the benefits of daily coffee consumption outweigh the risk.
“The bottom line is that we suggest [coffee] can be a good part of a healthy diet.”
– Robin Poole, University of Southampton
Science continues to suggest that coffee is good for you.
Based on a systematic umbrella review of 201 meta-analyses recently published in the BMJ, researchers from the University of Southampton found that moderate coffee consumption was more often associated with benefit than harm.
Drinking three to four cups of coffee a day showed the greatest benefit in terms of cardiovascular disease, coronary heart disease, and stroke, versus not drinking coffee. (Drinking coffee beyond these amounts was not associated with harm, but the benefits were less pronounced.)
Previous evidence suggested that coffee and tea could have a protective effect on liver tissue, but the results haven’t been conclusive. Now for the first time, scientists have confirmed the potential benefits of these beloved beverages.
