Coffee is one of the world’s most popular drinks.
Many studies have found that drinking a moderate amount of coffee may benefit health, including lowering the risk of heart disease, stroke, depression, and some long-term illnesses.
However, new research suggests that coffee may not be a good choice for everyone, especially people with very high blood pressure.
The study found that drinking two or more cups of coffee each day was linked to a much higher risk of dying from heart disease in people with severe high blood pressure.
The increased risk was seen in people whose blood pressure was at least 160/100 mm Hg. The findings suggest that people in this group may need to be more careful about how much coffee they drink.
The research was published in the Journal of the American Heart Association. Scientists studied the health and lifestyle habits of more than 18,000 adults between 40 and 79 years of age.
They compared coffee and green tea drinking habits with the risk of dying from heart disease over time.
The results showed that people with severe high blood pressure who drank two or more cups of coffee a day were about twice as likely to die from heart disease as people who did not drink coffee. In contrast, drinking only one cup of coffee each day was not linked to a higher risk. This suggests that the amount of coffee may be important.
Interestingly, the same problem was not seen with green tea, even though it also contains caffeine. The researchers believe this may be because green tea contains high levels of natural plant compounds called polyphenols. These substances have antioxidant and anti-inflammatory effects that may help protect the heart and blood vessels.
The findings do not mean coffee is harmful for everyone. For many healthy adults, moderate coffee drinking appears to be safe and may even provide health benefits. However, people who already have serious high blood pressure may react differently because caffeine can temporarily raise blood pressure and may place extra stress on the heart.
People with severe high blood pressure should continue following their doctor’s treatment plan. Taking blood pressure medicine as prescribed, checking blood pressure regularly, and attending medical appointments are all important for lowering the risk of heart attack, stroke, heart failure, and kidney disease.
Healthy lifestyle habits also make a big difference. Eating plenty of fruits, vegetables, whole grains, beans, nuts, and lean sources of protein can help support healthy blood pressure. Reducing salt, added sugar, and foods high in saturated fat is also recommended.
Regular physical activity is another key part of controlling blood pressure. Most adults should aim for at least 150 minutes of moderate exercise each week, such as brisk walking or cycling. Managing stress, avoiding smoking, and limiting alcohol can further improve heart health.
The researchers say their findings highlight the importance of personalized advice. If you have severe high blood pressure, talk with your doctor about whether your coffee intake is appropriate. Simple changes, such as cutting back on coffee or choosing green tea instead, may help reduce heart risks while still allowing you to enjoy a warm drink.
