Coffee may protect against head and neck cancers

Hello classmates, in this post, I am going to talk you about the article about the coffee, and potential health benefits it can have: Coffee may protect against head and neck cancers (http://www.guardian.co.uk/science/2010/jun/22/coffee-head-neck-cancers)

The study realized by Mia Hashibe de la Universidad de Utah, Salt Lake City, show that the people who consumed more than four cups of coffee a day, had a 39% lower risk of cancers of the oral cavity and pharynx combined, when compared with those who do not consume coffee.

These studies complement with news evidences of the benefits the caffeinated drinks. London scientists also found that the people that drink more of five cups of coffee or tea a day had a lower risk of a type of brain tumor.

Other studies also support you get benefits from drinking coffee, such as studies conducted by Harvard University in he last year, in which it was shown that men who drink coffee are 60% lower risk of developing aggressive prostate cancer, that the men who don’t drink coffee.

These results generate new perspectives for further investigations and thus understand the role of coffee in the prevention of head and neck cancer, since being studied by oral and pharyngeal cancer, provides some clues about a possible specific effect.
The studies realized by Hashibe, all display an association of caffeine with risk of cancer, which does not show the mechanisms of action or dose for that coffee is healthy.

The good thing about these studies is that based on large groups of initially healthy people in whom you see if the amount of coffee you drink affects their risk of cancer over time, and not as it was above where they made studies of people who drank coffee many years ago, in which only benefits were seen.

I hope this article has been interesting for you.
see you!
