1. Study Links Coffee and Tea to Longer Life

For many people, coffee and tea are among life’s greatest pleasures. It turns out that they may also promote heart health, reduce cognitive decline and extend life span. This study, from researchers at China’s Tianjin Medical University, analyzed data from nearly half a million people to determine if abstaining from coffee and tea, drinking one or the other, or drinking both beverages led to a longer life. What provides the greatest benefit?

3. What Makes the Mediterranean Diet Healthy? New Research Spotlights Polyphenols

An overwhelming body of research has established the health benefits of the Mediterranean diet, which includes fruits, vegetables, seafood, nuts, whole grains and olive oil, as well as moderate amounts of wine. The diet’s benefits are commonly thought to derive, in part, from its high levels of polyphenols, beneficial antioxidant molecules that may protect the body from aging, dangerous mutations and more. This Spanish study adds to our understanding of how our bodies metabolize the polyphenols found in foods and wine in the diet, and how those polyphenols could be working to help our bodies on a molecular level.

4. Innovative Research Finds Good News for Coffee Lovers

Recent studies have linked coffee to longer life and decreased risk of cardiovascular disease, among other potential health benefits. Yet for decades, conflicting research has suggested that coffee may actually lead to cardiovascular issues, particularly a type of dangerous irregular heartbeat called atrial fibrillation. This breakthrough study, led by researchers at the University of California San Francisco, provides strong evidence that coffee is likely safe for people worried about developing atrial fibrillation. What else does it mean for your daily cup of joe?

5. Moderate Drinkers Live as Long as Abstainers, Though Wine’s Health Benefits Remain Under Debate

For decades, researchers have tried to answer two seemingly simple questions: Is moderate alcohol consumption harmful? And does it provide any health benefits? A new study claims the answer to both questions is “No.” Crucially, however, it also found that moderate drinkers have approximately the same lifespan as people who don’t drink. What does the study mean for you?
