I love my cup of coffee, but this is what I found when researching it.
<The British Medical Journal reports that excessive consumption of coffee or other substances with a high caffeine content increases the possibility of a heart attack by raising blood cholesterol. While modest amounts of caffeine serve as a stimulant and can enhance individual performance both physically and mentally, in larger amounts it has an adrenalinelike effect that stresses the circulatory system by stimulating the heart and dilating blood vessels. Headaches, insomnia, and anxiety may result from consumption of more than three cups of coffee daily. Boiled coffee was said to contain five times as much caffeine as coffee prepared in other ways.>
With regard to tea:
<
Preliminary lab studies show that “a wide variety of commercial teas appear to either inactivate or kill viruses,” reports Reuters Health Information. Several types of green and black teas, regular and iced, were tested on animal tissues infected with such viruses as herpes simplex 1 and 2 and the T1 (bacterial) virus. According to researcher Dr. Milton Schiffenbauer of Pace University in New York, “iced tea or regular tea does destroy or inactivate the [herpes] virus within a few minutes.” Similar results were obtained with the T1 virus. While it is not yet clear how tea interferes with the survival of these viruses, researchers found that even after substantially diluting the tea, it was still effective. Black tea was found to have a somewhat more potent antiviral effect than green tea.>
So it would appear that although containing caffeine, drinking tea and coffee in moderation, can be beneficial.
