Coffee or Tea Which Drink Could Protect Your Heart

Updated on: October 25, 2024 10:20 pm GMT

Recent research has provided valuable insights into the effects of coffee and tea on stroke risk, revealing some surprising results. It seems that the age-old debate of coffee versus tea now has clearer health implications. A new study shows that drinking more than four cups of coffee a day increases the risk of stroke by 37%, while drinking black or green tea may actually lower this risk.

Key Findings from the Study

Coffee and Stroke Risk

The study, co-led by the University of Galway and McMaster University in Canada, highlights a concerning link between high coffee consumption and stroke risk. Specifically, researchers found:

  • Drinking more than four cups of coffee daily raises stroke risk by 37%.
  • Caffeine in coffee may contribute to higher blood pressure, which is a known risk factor for stroke.
  • The study did not specify different types of coffee, focusing instead on overall consumption.

The Impact of Fizzy Drinks

Apart from coffee, the research also examined the effects of fizzy drinks. It showed alarming results:

  • Consuming fizzy drinks, whether sugar-sweetened or artificially sweetened, doubles stroke risk.
  • The risk increases significantly with two or more fizzy drinks per day.
  • This connection is particularly strong in regions like Eastern and Central Europe, the Middle East, Africa, and South America.

The Protective Power of Tea

How Tea Helps Reduce Risk

In contrast to coffee and sugary drinks, both black and green tea have been linked to lower stroke risk. Drinking:

  • Three to four cups of black tea daily reduces stroke risk by 29%.
  • Three to four cups of green tea lowers the risk by 27%.

However, it’s important to note that adding milk to tea may negate these benefits by blocking the antioxidants responsible for the protective effects.

The Dangers of Juice Drinks

Interestingly, not all beverages are beneficial. The study warns about the risks associated with many fruit drinks. Specifically:

  • Juice drinks made from concentrates often contain added sugars and preservatives, which may increase stroke risk.
  • These drinks are linked to a 37% increase in the risk of stroke due to bleeding.
  • Women are found to be more vulnerable to these risks.

The Role of Hydration

A surprising twist in the findings indicates the importance of hydration. Drinking more than seven cups of water a day is associated with a lower risk of stroke caused by blood clots. Keeping hydrated may play a key role in maintaining overall health.

Expert Opinions

Lead researcher Professor Andrew Smyth emphasized, “Not all fruit drinks are created equal. Freshly squeezed juices are likely to be beneficial, but those made from concentrates can be harmful.”

Professor Martin O’Donnell, another expert involved in the study, reminded us that while controlling blood pressure is crucial, making healthier choices in our diet and being physically active can also significantly reduce stroke risk.

Conclusion

The findings of this international study, involving almost 27,000 participants, underscore the importance of beverage choices in relation to stroke risk. While coffee can be enjoyable, moderation is key. On the other hand, incorporating black or green tea and staying hydrated can be beneficial for heart health.

As we navigate our daily drink choices, it’s vital to consider these new insights. Regularly opting for tea or water, and limiting fizzy and sugary beverages, may not only satisfy our thirst but also promote a healthier lifestyle.
