Research shows that the benefits of coffee far more than a danger, said Dr. Tomas De Paulis, research scientist at Vanderbilt University's Institute for Coffee Studies. Coffee not only helps energize and sharpen the mind sufficient, but has been used to reduce heart attack or stroke and protect against some cancers, type 2 diabetes, heart disease and gallstones. There is also evidence that coffee can help stop headaches, improve mood and even prevent cavities. And a study presented at the Frontiers in Cancer Prevention Research conference in Houston, Texas shows that people who drink coffee regularly has the added benefit of significantly lowering the risk of aggressive prostate cancer.
The study, by researchers from the Channing Laboratory at Harvard Medical School and Harvard School of Public Health, was based on analysis of information from the Health Professionals Follow-Up Study, which included data on coffee drinking habits of 50,000 people from 1986 to 2006. During that period, 4975 of them suffered from prostate cancer, 846 cases of life-threatening because they have spread outside the prostate gland or grow aggressively. The review shows a clear relationship between the amount of coffee consumption and risk of prostate cancer. People who drink six cups of coffee or more per day of nearly 60 percent less likely to suffer from prostate cancer and 19 percent less likely to develop all forms of prostate cancer than men who do not drink coffee.
Some of the reported benefits of coffee are a direct result of the high caffeine content. Eight-ounce cup of coffee contains about 85 mg. But the researchers say the fact that the same risk reduction seen irrespective of whether the ordinary man or drink decaffeinated coffee is not caffeine but it shows the influence of coffee on insulin and hormone levels that cause a positive effect on prostate cancer risk. "Coffee has an effect on insulin and glucose metabolism, as well as sex hormone levels, which all play some role in prostate cancer," said lead author Dr. Kathryn M. Wilson, research fellow in epidemiology at the Harvard School of Public Health.
