Caffeinated coffee lower oral cancer risk

Source: articles.timesofindia.indiatimes.com Author: staff A new American Cancer Society study has found a strong inverse association between caffeinated coffee intake and oral/pharyngeal cancer mortality. The researchers revealed that people who drank more than four cups of caffeinated coffee per day were at about half the risk of death of these often fatal cancers compared to those who only occasionally or who never drank coffee. But they said that more research is needed to elucidate the biologic mechanisms that could be at work. Previous epidemiologic studies have suggested that coffee intake is associated with reduced risk of oral/pharyngeal cancer. To explore the finding further, researchers examined associations of caffeinated coffee, decaffeinated coffee, and tea intake with fatal oral/pharyngeal cancer in the Cancer Prevention Study II, a prospective U.S. cohort study begun in 1982 by the American Cancer Society. Among 968,432 men and women who were cancer-free at enrollment, 868 deaths due to oral/pharyngeal cancer occurred during 26 years of follow-up. The researchers found consuming more than four cups of caffeinated coffee per day was associated with a 49 percent lower risk of oral/pharyngeal cancer death relative to no/occasional coffee intake (RR 0.51, 95 percent confidence interval. A dose-related decline in relative risk was observed with each single cup per day consumed. The association was independent of sex, smoking status, or alcohol use. There was a suggestion of a similar link among those who drank more than two cups per day of decaffeinated coffee, although that finding was only marginally significant. No [...]

Green tea’s status as a ‘superfood’ grows: A study finds it even abolishes bad breath (it already helps prevent cancer and heart disease)

Source: www.dailymail.co.uk Author: staff Green tea can help beat bad breath, according to scientific research. The study found that antioxidants in the tea, called polyphenols, destroy a number of compounds in the mouth that can lead to bad breath, tooth decay and even mouth cancer. The study from Israel’s Institute of Technology will add to green tea’s status as one of nature’s so-called ‘superfoods’. It is already said to help prevent cancer and heart disease and lower cholesterol – and even ward off Parkinson's and Alzheimer's. Writing in the Archives of Oral Biology, the scientists called for more studies, adding: ‘All together, there is increasing interest in the health benefits of green tea in the field of oral health.’ Green tea is made from the same plant as black tea but processed in a different way that means it retains less caffeine and more polyphenols. It has been drunk in China and the Far East for thousands of years and is fast becoming popular in Britain particularly because of its health benefits. It is also more likely to be drunk without milk or sugar so it tends to contain fewer calories too. The study, published in the journal Archives of Oral Biology, examined the properties of the polyphenol called epigallocatechin 3 gallate (EGCG) in particular. It reported: ‘EGCG constitute the most interesting components in green tea leaves. ‘Tea polyphenols possess antiviral properties, believed to help in protection from influenza. ‘Additionally green tea polyphenols can abolish halitosis through modification of odorant sulphur [...]

Berry Nutrition

Source: www.foodproductdesign.com Author: Marie Spano, M.S., R.D., Contributing Editor Nutritionally speaking, good things come in sweet—and tart—little packages. Research is discovering berries pack a nutritional punch due to their vitamin, fiber and antioxidant content. Botanically speaking, berries are indehiscent fruits (they don’t need to be opened to release their seeds) that ripen through the ovary wall. However, any small, edible fruit with multiple seeds is typically considered a berry. In addition to lending flavor and brilliant colors to a wide variety of dishes, all berries are packed with an array of antioxidants, nutrients and potential health benefits. Berries that are especially antioxidant-rich include fresh crowberries, bilberries, black currants, wild strawberries, blackberries, blueberries, goji berries, sea buckthorn, blueberries and cranberries. However, the antioxidant content of berries varies based on the geographical growing condition. And, while fresh berries are an excellent source of antioxidants, total phenol content drops during processing. In fact, processed berry jams and syrup contain approximately half the antioxidant capacity of fresh berries, and juices show the greatest loss of anthocyanins and tannins due to the removal of seeds and skin (Nutrition Journal, 2010; 9:3; Journal of Agricultural and Food Chemistry, Jan 13, 2012). Botanical berries Shiny, scarlet-colored cranberries are rich in vitamin C, loaded with antioxidants, including flavonoids, and score higher in their ORAC score than many other fruits ("Oxygen Radical Absorbance Capacity (ORAC) of Selected Foods—2007", USDA ARS). Cranberries are perhaps best known for the role their juice plays in the prevention of urinary tract infections (UTI) [...]

Blueberries contain vital polyphenols that could contribute to a decline in obestiy

Source: Medical News Today Last week it was reported that strawberries may help treat throat cancer, now a new study shows how blueberries may aid in curbing obesity. Plant polyphenols have been shown to fight adipogenesis, which is the development of fat cell, and induce lipolysis, which is the breakdown of lipids and fat. The study was done to evaluate whether blueberry polyphenols play a role in adipocyte differentiation, the process in which a relatively unspecialized cell acquires specialized features of an adipocyte, an animal connective tissue cell specialized for the synthesis and storage of fat. Polyphenols occur in all plant foods and contribute to the beneficial health effects of vegetables and fruit. Their contribution to the antioxidant capacity of the human diet is much larger than that of vitamins. The total intake in a person's diet could amount to 1 gram a day, whereas combined intakes of beta-carotene, vitamin C, and vitamin E from food most often is about 100 mg a day. Phenolic acids account for about one third of the total intake of polyphenols in our diet, and flavonoids account for the remaining two thirds. Flavonoids are further subdivided into several categories. Shiwani Moghe, a graduate student at Texas Woman's University said: "The promise is there for blueberries to help reduce adipose tissue from forming in the body I wanted to see if using blueberry polyphenols could inhibit obesity at a molecular stage. We still need to test this dose in humans, to make sure there are [...]

Cancer risk reduction study reports green tea extracts may protect against oral cancer

Source: baileyshealthstore.wordpress.com Author: staff Over 50 per cent of participants in the University of Texas M. D. Anderson Cancer Center study experienced a clinical response to the green tea extracts, according to findings published in Cancer Prevention Research. “While still very early, and not definitive proof that green tea is an effective preventive agent, these results certainly encourage more study for patients at highest risk for oral cancer,” explained the research team. “The extract’s lack of toxicity is very crucial in prevention trials. It’s very important to remember that these are otherwise healthy individuals and we need to ensure that agents studied produce no harm,” they added. Green tea contains between 30 and 40 per cent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 per cent. Oolong tea is semi-fermented tea and is somewhere between green and black tea. The four primary polyphenols found in fresh tealeaves are epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), and epicatechin (EC). The study followed 41 people with oral leukoplakia, a condition is a sign of oral cancer risk. The participants were assigned to receive either placebo or green tea extract at one of three doses, including 500 milligrams or 1,000 mg three times a day. The researchers collected oral tissue biopsies, which they say was “essential in that it allowed us to learn that not only did the green tea extract appear to have benefit for some patients, but we pointed [...]

Green tea shows promise as chemoprevention agent for oral cancer, M. D. Anderson study finds

Source: www.eurekalert.org Author: press release Green tea extract has shown promise as cancer prevention agent for oral cancer in patients with a pre-malignant condition known as oral leukoplakia, according to researchers at The University of Texas M. D. Anderson Cancer Center. The study, published online in Cancer Prevention Research, is the first to examine green tea as a chemopreventative agent in this high-risk patient population. The researchers found that more than half of the oral leukoplakia patients who took the extract had a clinical response. Long investigated in laboratory, epidemiological and clinical settings for several cancer types, green tea is rich in polyphenols, which have been known to inhibit carcinogenesis in preclinical models. Still, clinical results have been mixed. "While still very early, and not definitive proof that green tea is an effective preventive agent, these results certainly encourage more study for patients at highest risk for oral cancer," said Vassiliki Papadimitrakopoulou, M.D., professor in M. D. Anderson's Department of Thoracic/Head and Neck Medical Oncology, and the study's senior author. "The extract's lack of toxicity is attractive - in prevention trials, it's very important to remember that these are otherwise healthy individuals and we need to ensure that agents studied produce no harm." In the Phase II dose-finding study, 41 M. D. Anderson oral leukoplakia patients were randomized between August 2002 and March 2008 to receive either green tea extract or placebo. Participants took the extract, an oral agent, for three months at one of three doses - 500 per [...]
