1. Study on coffee consumption and health benefits: A recent study conducted by researchers from Hungary and the UK explored the potential benefits of drinking coffee in reducing overall mortality and improving cardiovascular health. They analyzed data from 468,629 participants in the UK Biobank. 

2.

Coffee consumption categories: Participants were categorized based on their daily coffee intake: non-drinkers, moderate to low intake (0.5-3 cups/day), and high intake (>3 cups/day). 

3. Benefits of moderate coffee consumption: Those who consumed 0.5-3 cups of coffee per day experienced a 12% reduction in overall mortality risk, a 17% reduction in mortality risk due to cardiovascular diseases, and a 21% reduction in stroke risk compared to non-drinkers.

4. No additional benefits of excessive coffee consumption: Consuming more than 3 cups of coffee per day did not provide any extra health benefits. 

5. Health benefits limited to freshly ground coffee: The study found that the benefits were specifically associated with freshly ground coffee. Instant coffee did not show any improvement in health outcomes.
