Many people drink coffee to quickly increase their energy. Scientists say there may be another reason to drink coffee. They studied the link（联系）between coffee drinking and the risk of death from some diseases, and found that drinking moderate（适量的）amounts of coffee each day may help protect against heart disease, cancer and other diseases. David Jacobs of the University of Minnesota in Minneapolis worked on the study with researchers from the University of Oslo.
The researchers used information about 27,300 women. They were between 55 and 69 years of age when they entered the study. During a fifteen-year period, almost 15.75% of them died. The researchers found a link between the amount of coffee the women reported drinking and their risk of dying from heart disease. Coffee drinking was measured in cups. One cup is about 225 grams.
There was a reduced risk of death from heart disease among women who drank from one to three cups of coffee each day. A reduction（减少）in the risk of death from other diseases was also seen. But Professor Jacobs says the risk reduction for death from heart disease decreased in women who drank more than three cups a day.
The researchers say antioxidants（抗氧化剂）in coffee might reduce the risk of heart disease. Earlier studies found that coffee has high levels of antioxidants. Antioxidants have been shown to help prevent heart disease, cancer and other diseases.
