Coffee Drinking Linked to Longer Life

           The AARP tested 400,000 healthy men and women between the ages of 50 and 71 for
around thirteen years and 13% of the participants died. Coffee helps prevent chronic diseases such as heart disease, and diabetes. Some people believe this and some people believe the opposite. The coffee drinkers in this study are 10% to 15% less likely to die during the study. Cancer was the only major cause of death not associated with coffee consumption. Other causes of death that was associated with coffee are heart disease, lung disease, pneumonia, stroke, diabetes, infections, and injuries/accidents. People don't have to worry that coffee might increase the risk of death. Even a little bit of coffee was significant in living longer. One cup a day was more common that six cups a day proved that drinking coffee was a lower risk of dying 6% for men and 5% for women. The results might not be from the coffee itself, but from characteristics of the people drinking the coffee. Both decaf and regular coffee were used and associated with lower risk of dying.
          I think that the AARP should try to straighten their facts out so that people who want to stay healthy know whether or not to drink coffee or not. For some people, coffee is necessary. If they don't drink coffee they will fall asleep during their day. But for others, coffee isn't necessary so they can decide to drink it or not. I think if it is healthy, scientists and doctors can try to find out what characteristic of the coffee makes it healthy so that they can apply it to more foods. Also more people can drink coffee if it does have a health benefit.
