Recently, there have been several publications on the beneficial and protective effects of tea and coffee on human. Those include cardiovascular health, effect alertness of a person, diabetes and on general health. Now, it has been observed that drinking of coffee or tea at least 3.5 ounces of coffee or tea per day may lower the incidence of brain tumor.
As per a study published in the American Journal of Clinical Nutrition, come from an ongoing study in 10 European countries investigating potential risk factors for cancer. At the outset, 521,488 men and women between the ages of 25 and 70 completed detailed questionnaires on their medical history, diet, exercise habits, smoking and other lifestyle factors.
For their analysis, Michaud's team focused on more than 410,000 participants who were cancer-free at the outset and had complete dietary information. Over an average of 8.5 years of follow-up, 343 of these men and women were diagnosed with glioma; another 245 were diagnosed with another, usually benign type of brain tumor called meningioma.
When the researchers divided the study participants into four to five groups based on their coffee and tea intake at the outset, they found no evidence of a "dose-response" relationship -- that is, a decreasing glioma risk as coffee and tea consumption climbed.
The findings were different, however, when the researchers looked at two groups: those who averaged at least 3.5 ounces of coffee or tea per day, and those who drank less or none at all.
A recent lab study, for example, found that caffeine appeared to slow the growth of a type of glioma called glioblastoma. In addition, both coffee and tea contain antioxidants, which help protect body cells from damage that can lead to cancer and other diseases.
