The average American drinks about three and a half cups of coffee a day. Coffee naturally contains caffeine, which stimulates the central nervous system, increases blood pressure, and raises the metabolic rate. Because of this, some have concluded that the effects of drinking coffee increases your risk of developing cardiovascular disease.
Some research has shown that there are benefits of drinking coffee in moderate amounts, such as its ability to lower a person’s risk of developing conditions like type 2 diabetes, Parkinson’s disease, colon cancer and liver cancer. If you are a healthy adult there is nothing wrong with drinking coffee but for children, adolescents, the elderly and those who have hypertension, drinking coffee may negatively affect you.
