A research conducted by a group of Italian scientists found one new reason in support of the claim that Italians lead one of the healthiest lifestyles in the world. They discovered that drinking more than three cups of coffee a day could reduce the risk of developing prostate cancer.
The study was published in the International Journal of Cancer, and looks at the effects of caffeine on prostate cancer. This issue has been debated for a long time, as many scientists knew of the antitumor effect of coffee. Thus, they thought that it might protect the consumers from developing the disease.
Providing scientific evidence that coffee works against cancer
George Pounis, one of the authors of the study, declared that many studies dealt with this issue, but most of them lacked the scientific evidence needed to prove that coffee could indeed protect against prostate cancer. Thus, they wanted that this study should settle the debate and provide all the necessary materials.
For four years, the researchers observed a number of almost 7,000 participants, both locals from the city of Molise or people who agreed to be a part of the Moli-sani study. They looked at how often these people drank coffee, and then compared these results with the number of prostate cancer cases reported during the period.
Thus, researchers observed that those people who consumed more than three cups of coffee per day had a 53 percent smaller risk of developing prostate cancer. As they wanted their study to be as accurate as possible, they decided to test the hypothesis in the laboratory.
Caffeine has the miraculous effect against cancer cells
They looked at the effect of coffee extract on prostate cancer cells. They tested both caffeinated and decaffeinated coffee, and they observed that only the caffeinated type could reduce the growth of cancer cells, thus preventing metastasis.
Thus, the researchers concluded that caffeine was the one responsible with stopping cancer development, and the other substances present in coffee played no role whatsoever in this process. However, they warn people about certain aspects they should keep in mind.
The study concentrated only on a certain sample of population, namely the people from Molise. They prepare their coffee after the Italian recipe, so it might be different from the coffee drunk in other parts of the world.
Thus, they would like to continue their study and broaden it to different types of coffee, which might contain more bioactive substances. Therefore, the results might be different for people from other parts of the world who drink other types of coffee.
