When it comes to your daily pick-me-up, coffee and tea are often the go-to choices. Both beverages claim to offer an array of health benefits, from boosting energy levels to reducing inflammation. But when it comes to the ultimate question—do they pose a risk to your heart? New research might just surprise you.
A recent international study, published in the International Journal of Stroke, analyzed the consumption habits of nearly 27,000 adults from 32 countries. The results reveal a striking difference between coffee and tea when it comes to stroke risk. While tea seems to be a heart-healthy option, coffee might be a little more dangerous than you think.
Coffee: The Double-Edged Sword
Coffee lovers, take note: the study suggests that drinking more than four cups a day could increase your stroke risk by nearly 40%. While a steaming mug of coffee might give you that necessary caffeine kick, the side effects of too much coffee are not to be ignored. Experts point to the high caffeine content in coffee—around 80-100 milligrams per 8-ounce cup—which can raise heart rate and blood pressure. Over time, these changes can damage blood vessels, making them more vulnerable to clots that can lead to a stroke.
Interestingly, while moderate coffee drinkers (those having three cups or less a day) did not show an increased risk of stroke, the impact of excessive consumption is clear. The study suggests that high coffee intake is linked to other health issues, such as hypertension, which in turn elevates the risk of cardiovascular events.
Tea: The Heart-Healthy Alternative?
On the other hand, tea emerges as a more heart-friendly choice. The study found that drinking four or more cups of tea daily reduced stroke risk by 19%. Whether it’s a rich, bold black tea or a delicate green tea, this seemingly innocent brew appears to offer protective benefits for the heart and brain.
Among the various types of tea, black tea stands out as the most protective. It lowered stroke risk by 29%, while green tea followed closely behind with a 27% reduction in risk. So, why is tea so beneficial for your heart? Researchers attribute this to the antioxidants found in tea, which help to fight inflammation and support overall cardiovascular health.
The Dairy Dilemma
However, there’s a catch: adding milk to your tea could cancel out its stroke-protective properties. According to the researchers, milk binds to antioxidants, preventing them from being absorbed by the body. This means that while tea itself can lower stroke risk, your beloved cup of milk tea might not offer the same health benefits.
The Bottom Line
So, what’s the verdict? If you’re looking to protect your heart and reduce the risk of stroke, tea seems to be the clear winner. Coffee, in moderation, doesn’t pose significant risks, but drinking it in excess could raise your blood pressure and heart rate, both of which increase stroke risk. Tea, especially when consumed without milk, offers a healthier alternative.
Remember, though, that this study doesn’t account for all the factors that contribute to heart health, such as diet and exercise. But if you’re trying to make a heart-smart decision in your daily beverage choice, tea might just be the way to go.
