A recent long-term study found that drinking more than one cup of coffee a day can be very dangerous for people with high blood pressure. In some cases, it can even cause a heart attack that kills the person.
Coffee is also thought to help prevent many diseases, but it can also hurt you in some ways.
Japanese experts studied the effects of coffee and green tea on blood pressure for 19 years, according to a study that was published in a medical journal.
People between the ages of 40 and 79 took part in the study, which took place between 1988 and 1990.
In the study, 6,500 men and 12,000 women were re-examined after 19 years and asked a number of questions. The study also looked at the data of people who died during this time.
Experts found that 842 of the people who signed up for the study died during the study from heart disease.
People who died of heart diseases, like a heart attack, had high blood pressure and drank more than one cup of coffee every day, according to the data.
People with high blood pressure who drank one cup of coffee and one cup of green tea every day were less likely to get heart disease, according to the study.
Experts say that there are 100 mg of caffeine in 8 ounces of coffee and 50 mg of caffeine in 8 ounces of green tea.
Experts have said that heart diseases could be caused by too much caffeine and that people with high blood pressure shouldn’t drink more than one cup of coffee a day.
At the same time, experts pointed out many other benefits of coffee and said that it helps protect against deadly diseases like cancer and diabetes type 2.
