Drinking two or more cups of coffee a day was associated with twice the risk of death from cardiovascular disease among people with severe hypertension, according to researchers at Institute for Global Health Policy Research, Bureau of International Health Cooperation, National Center for Global Health and Medicine in Tokyo, Japan.
What to Know
People with severely high blood pressure who drink two or more cups of caffeinated coffee each day could double their risk of dying from a heart attack, stroke, or any type of cardiovascular disease.
Too much coffee may raise blood pressure and lead to anxiety, heart palpitations, and difficulty sleeping.
An 8-ounce cup of coffee has 80 to 100 mg of caffeine, while an 8-ounce cup of green or black tea has 30–50 mg.
Drinking one cup of coffee a day or any amount of green tea was not associated with risk of death across any blood pressure categories, and drinking green tea was not associated with increased risk of death related to cardiovascular disease at any blood pressure level.
Frequent consumers of coffee were more likely to be younger, current smokers, current drinkers, to eat fewer vegetables, and to have higher total cholesterol levels and lower systolic blood pressure regardless of their blood pressure category.
