Good news for coffee lovers! A recent study from Semmelweis University suggests that drinking up to three cups of coffee a day may help lower the risk of stroke and fatal heart disease.
For years, the effects of coffee on heart health have been debated. Some people worry about its impact on blood pressure and heart rate, while others believe it has protective benefits. To gain a clearer understanding, researchers examined how regular coffee consumption influences the risk of heart attacks, strokes, and overall mortality.
What the Study Found
The study used data from the UK Biobank, which tracked 468,629 adults with an average age of 56 years. At the start of the study, none of the participants had heart disease. Researchers followed them for 10 to 15 years to observe health outcomes.
Participants were divided into three groups based on their coffee habits:
- Non-coffee drinkers (22.1%)
- Light-to-moderate drinkers (0.5 to 3 cups per day, 58.4%)
- Heavy coffee drinkers (more than 3 cups per day, 19.5%)
The results were quite interesting:
- People who drank 0.5 to 3 cups daily had a 12% lower risk of death from any cause.
- Their risk of dying from heart disease was 17% lower than non-coffee drinkers.
- Their risk of having a stroke was 21% lower.
This suggests that moderate coffee consumption could have protective effects on the heart and overall health.
Coffee and Heart Structure
To understand why coffee might be beneficial, researchers analyzed heart images from 30,650 participants using cardiac MRI scans. They found that regular coffee drinkers had healthier heart size and function, suggesting that coffee might help slow down age-related heart changes.
Why Does Coffee Help?
The exact reasons behind coffee’s heart benefits are still unclear. However, scientists believe that certain compounds in coffee may help:
- Improve heart function
- Reduce inflammation
- Support better blood circulation
While these findings are promising, more research is needed to confirm the effects and determine how coffee interacts with different heart conditions.
Should You Drink More Coffee?
If you already enjoy coffee, this study suggests that drinking up to three cups a day may be part of a heart-healthy lifestyle. However, individual health conditions vary, and some people may need to limit their intake due to caffeine sensitivity or other health concerns.
As always, it’s best to consult a doctor before making changes to your diet, especially if you have existing health conditions.
This study adds to growing evidence that coffee might offer more than just a morning boost—it could also support long-term heart health.
