A recent study on the health benefits of tea and coffee has revealed that tea and coffee drinkers have lower risk of developing malignant brain tumors. Led by Dominique Michaud of the Brown University in Rhode Island, the researchers have discovered that increasing coffee and tea consumption can lower a person’s likelihood of developing gliomas. These are brain tumors typically found in the area of the brain called the brainstem, and which are considered to be malignant. But researchers have added that the research does not give any sufficient indication to suggest that drinking coffee and tea can protect a person from developing brain cancer. Michaud said that the results had only given them preliminary evidence and it’s not sufficient enough to advise people to increase their usual coffee and tea consumption.
Understanding Brain Cancer The impact of the discovery may have very little relevance since having malignant brain tumors and brain cancer is very rare. Annual rates for brain cancer in Europe is 4 to 6 cases per 100,000 of the population in women and 6 to 8 cases per 100,000 of the population in men. A person has a very small 1 percent chance of developing brain tumors in his lifetime. The primary relevance of the study is in finding out the reason behind the development of malignant brain tumors. Medical science is still unable to provide a clear explanation of how and why a person develops malignant brain tumors. Unlike other types of cancer, brain cancer is yet to be understood better. The rare occurrence of the disease is also one contributory factor why there has been lesser attention put into the matter compared to other diseases. But researchers at Brown University are working to unravel the mystery by further establishing the relationship between coffee and tea, and malignant brain tumors. One of the methods used in understanding the cause and behavior of a disease is by understanding its relationship with the substances that inhibits its development. The researchers will continue to work their way through the labyrinth in the hopes of establishing their cause-and-effect relationship. What the Studies Say The findings of the ongoing study on the risk factors of cancer in ten European countries were published in the American Journal of Clinical Nutrition. The study consists of 521,488 participants of both men and women, aged 25 to 70. They were asked to answer a questionnaire regarding their exercise habits, diet, medical history and other lifestyle factors. The team focused their attention on the majority of the group who did not have cancer and who were able to give out a complete and comprehensive summary of their daily diet. After 8 and a half years, 588 of the participants developed brain tumors of which 343 had glioma and 245 with meningioma, another type of malignant brain tumor. The researchers divided the participants into four groups according to their coffee and tea consumption. With a certain group, they found no strong indication that higher dosage resulted to a lesser tendency of developing malignant brain tumor. But two of the groups, consisting of participants who drank at least 3.5 ounces of tea or coffee a day, had one-third lesser tendency of being diagnosed with glioma compared to the non-drinkers or those who consumed less than the regular drinkers. The confusing but evocative results may have been caused by the nature of the data. The study’s accuracy all depended upon the information provided by the participants and all of them are self-reported with no systematic verification process. But Michaud said that coffee and tea can lower the risk of developing glioma through a biological perspective. In a related study, caffeine was discovered to decrease the growth rate of glioblastoma, a type of glioma. Coffee and tea are also well known rich sources of antioxidants which have been proven to have preventive properties over cancer and other serious health problems. Health Benefits of Coffee Millions of people around the world look forward to having a cup of coffee every morning and before they go to work. The love for coffee seems to be the most common denominator for most people. It is the pleasure of having a hot cup in your hands and experiencing increased vibrancy in every sip that makes people extremely fond of this dark beverage. But aside from its good taste and enticing aroma, the much-loved coffee has been proven by different studies to have several health benefits. From being a strong antioxidant to promoting healthy skin, the health benefits of coffee seem to have infinite possibilities. Due to its high and efficient antioxidant content, the largest-funded study on the health benefits of coffee is focused on coffee's influence over cancer. According to an early study conducted by the International Agency Research on Cancer or the IARC, coffee can be categorized as a possible carcinogenic for developing bladder cancer. But several studies following the previous observation have invalidated the link between coffee consumption and bladder cancer. In 2010, coffee is being considered as one of the most studied product in the world. Though it has been thought to cause cancer, recent studies are beginning to prove otherwise. Studies also show that people with high coffee consumption have lower risk of developing the following health conditions:
People with regular coffee intake have also been found to:
Beauty products has also been featuring coffee as a main ingredient, citing its antioxidant properties as also effective when applied from the outside. Health Benefits of Tea There are many kinds of teas available in the market today but all of them would always pride of having a relaxing and soothing effect both to the body and the mind. However, aside from the sensual experience, the ancient beverage has shown indications of being effective in improving a person's health and overall quality of life. Women with ages 60 and above who drink tea as part of their daily routine are 60 percent less likely to suffer from rheumatoid arthritis than non-drinkers. Prolonged tea consumption has also been observed to have positive effects on a person's bone density, thereby helping in the prevention of osteoporosis. People who drink tea on a daily basis for more than ten years have been discovered to have higher bone mineral density than people who don't. Studies dedicated to the validation of preliminary evidences provided by earlier studies regarding the potential anti-cancer properties of tea are being conducted around the world, and researchers are looking closely at polyphenols in tea as a possible inhibitor for some processes that results to the development of cancer.
