Green tea reduces risk of early death

grn_tea.jpgBack when I was in Austin, I worked with a girl from China, her accent was very hard to understand, and her database administration was a bit heavy handed, but for the most part she knew what she was doing. Also, she would drink green tea practically all the time. Knowing it was good for you, I and another chap started the practice, which I’ve carried on (off and on that is) until present day. Now in a desk drawer I have a box of green tea, and make hot or cold cups during the day, depending on the temperature and my mood. Seems like I may want to up my consumption, and it’ll be easy since I drink so much water during the day, I’ll just chuck in a bag and sip away. So even though it’s been known to be healthy, now it’s even more so according to dr_grn_tea.jpga new study reported in the September 13th Journal of the American Medical Association: drinking green tea lower’s risk of death due to cardiovascular disease *and* another study that claims it may curb prostate cancer in men at risk. “Adults in Japan who consumed five or more cups of green tea a day had a lower risk of death due to cardiovascular disease, according to a new study. Researchers from Japan examined the association between green tea consumption and death due to cardiovascular disease (CVD), cancer, and the overall death rate within a large population. Eighty percent of the population in this region drinks green tea, and more than half consume three or more cups a day. The study included 40,350 adults in northeastern Japan between 40 and 70 years of age. None of them had any history of stroke, coronary heart disease, or cancer at the beginning of the study. The participants in this study were followed for 11 years, from 1995 to 2006. During the 11 years in which the study took place, 4,209 participants died. More than 800 of the participants died of cardiovascular disease, and 1,134 died of cancer. Researchers then compared participants who drank less than one cup of greengrn_tea_field.jpg tea a day to those who drank at least five cups a day. Participants who consumed five or more cups a day had 16-percent lower risk of CVD-related death. The association between green tea consumption and lower risk of CVD was higher among women. Of just the female participants, those who consumed five or more cups a day had a 31-percent lower risk of CVD-related death compared to those who drank less than one cup a day. “Green tea may prolong your life through reducing heart disease and stroke,” Kuriyama tells WebMD. “Our findings might explain the differences in mortality profile between Japan and the United States. The Japanese age-adjusted rate of mortality due to [heart disease and stroke] is about 30 percent lower than that of the United States.”” You can find the offical JAMA report here.

Meanwhile, Dr. Saverio Bettuzzi from the University of Parma in Italy reveals his study that showed that, “after a year, only 1 man among 32 in the GTC (green tea catechins) group developed prostate cancer, a rate of only 3 percent. In contrast, 9 out of 30 men treated with placebo developed prostate cancer, for the expected rate of 30 percent. The investigator performed a trial involving men with high-grade PIN, who were given an inactive placebo preparation or one containing 600 milligrams of GTCs daily, “equivalent to 12-15 cups of green tea infusion, that is about two times the average intake in Asian countries.” “To our knowledge, this is the first study showing that GTCs have potent in vivo chemoprevention activity for human prostate cancer,” Bettuzzi noted. “There are other studies strongly suggesting that similar results could be obtained for prevention of other types of cancer. As a matter of fact, breast and colon cancer are possible targets. In the near future, we are supposed to start a collaborative trial involving both Italy and USA on this matter,” Bettuzzi concluded.” And yes, I’ve already drank 2 cups of green tea this morning!

    Steep Risk

    Claim: “Sun tea” (tea brewed by being left to steep in sunlight) can harbor dangerous bacteria.

    Status: True.

    Example: [Collected via e-mail, 2006]

    I heard that making sun tea (putting tea bags in a container of water and putting the container outdoors in the sun) can be poisonous because the water needs to be boiled. True or not?

    Origins: As the weather warms up, people look for ways to cool off. One of the methods habitually resorted to is making alterations in their choices of beverage, with most folks tending to reduce their
    intake of hot drinks in favor of chilled or room temperature potables. (Which is not to say that choice is necessarily right — there is a school of thought that advocates beating the heat with hot beverages rather than cold.)

    Sales of iced tea and sodas can be counted upon to increase in the summer. So too does interest in “sun tea” grow as the mercury rises, prompting folks to look for less costly hot weather replacements for their more usual coffee and tea. Sodas and juices are expensive, after all, and there is only so much water one can drink without becoming heartily sick of it. At first glance, sun tea appears a viable and healthful alternative, harnessing as it does the energy of the sun to produce a zero-calorie drink one would presume contains all the benefits of tea brewed in the more usual fashion.

    Yet therein lies the rub. Tea made by placing loose or bagged tea leaves in glass jars of water which are then left in direct sunlight can harbor bacteria that can make you ill.

    According to the Centers for Disease Control, using the sun’s rays to make tea can facilitate the growth of bacteria. Tea steeped in a jar on your porch won’t get any hotter than 130° Fahrenheit, about the temperature of a really hot bath and not nearly hot enough to kill nasties lurking either in the water or on the tea itself. For that, water needs to be heated to 195° for three to five minutes.

    Alcaligenes viscolactis, a bacteria commonly found in water, consequently turns up in sun tea. While the caffeine in black tea will help prevent that microbe from flourishing for a few hours, its effects won’t last beyond that. Herbal teas are an even worse bet for brewing in sunlight because they tend to lack caffeine, which means even that barrier to Alcaligenes viscolactis turning your summertime drink into its own breeding ground is missing.

    Better to brew tea the more usual way with boiling water than to risk giving up any of your summer to illness caused by what you drank.

    The following rules have been recommended for those who brew sun tea:

    * Use a container that has been scrubbed in warm, soapy water. As an additional precaution, dip the container in a bleach solution made with 1-1/2 teaspoons to 1 tablespoon of bleach per gallon of water.

    * If the container has a spigot, clean it carefully after each use, preferably by taking it apart. If you can’t clean inside the spigot, don’t brew sun tea in that vessel — find yourself something else to use.

    * Do not leave tea to brew in the sunlight for more than three to four hours.

    * Do not prepare more tea than you plan to use that day.

    * Refrigerate the drink as soon as it is ready and keep it refrigerated.

    * Discard tea if it appears thick or syrupy. Those ropy strands are bacteria.

    A safer alternative to “sun tea” is “refrigerator tea.” To make it, fill a pitcher with a quart of cold water, add four to six tea bags, and refrigerate it at least six hours or overnight. Squeeze and remove the tea bags, and serve the tea over ice.

    Here’s a factoid from ‘Men’s Health’ that I read months ago and have been trying to find. Now I know which green tea I need to shop for.

    It’s in the Bag
    Choose the tea with the most health benefits

    Edited by: Adam Campbell

    Green tea is widely known for its health benefits. You can thank its high content of catechins, antioxidants that help fight both cancer and heart disease. But a recent USDA study found that the amount of these healthy compounds — as well as the amount of caffeine — varies widely among commercially available teas. See how several of the top brands compare per 8-ounce cup, then choose wisely: Stash Darjeeling Organic Green Tea has the most catechins — measured in milligrams per gram — of any green tea tested.

    Tea vs. Tea

    Stash Darjeeling Organic Green Tea
    TOTAL CATECHINS: 100
    CAFFEINE: 22 milligrams (mg)

    Peet’s Sencha Japanese Green Tea
    TOTAL CATECHINS: 76
    CAFFEINE: 17 mg

    Lipton 100% Natural Green Tea
    TOTAL CATECHINS: 29
    CAFFEINE: 8 mg

    Celestial Seasonings Green Tea
    TOTAL CATECHINS: 19
    CAFFEINE: 6 mg

    seven cups ( http://www.sevencups.com/ ) or special teas ( http://www.specialteas.com/ ) would be my two top choices

    Recently… white tea has been seen to be even more healthier than green tea.
    It acts more for weight loss…has tons more antioxidants and is also good as an anti aging solution.
    What do you think?…is there a white tea revolution coming?
