Can Coffee Keep Your Heart Healthy?
Published: Jun 27, 2024
This article explores the effects of caffeine, especially from coffee, on heart health. Learn how your daily cup of joe might impact your cardiovascular system.
Caffeine Sources and Consumption
Caffeine is found in coffee, tea, and soft drinks, making it the most consumed stimulant worldwide. Coffee and tea each contain about 100 mg of caffeine per serving, while colas have about 50 mg, and energy drinks can have up to 250 mg. Given its widespread consumption, understanding caffeine's effects on health is crucial.
Heart Health and Caffeine
Moderate caffeine consumption, up to six cups of coffee per day, doesn't seem to worsen heart disease outcomes. Studies show that people drinking three to four cups daily might even have a lower risk of stroke compared to non-drinkers. However, those with heart palpitations might benefit from reducing caffeine intake.
Impact on Blood Pressure
Caffeine can raise blood pressure temporarily, especially in non-regular drinkers. While chronic coffee consumption's impact on blood pressure is less clear, studies suggest a slight increase in blood pressure might occur. Switching to decaffeinated coffee could help with blood pressure management.
Coffee and Cholesterol
Filtered coffee generally has no significant effect on cholesterol levels. However, non-filtered coffee can raise cholesterol due to compounds like cafestol. For those concerned about cholesterol, sticking to filtered coffee might be beneficial.
