The Mixed News on Cancer And Green Tea
If you're taking green tea solely for the disease protection, you could be interested in the results of a systematic review of studies that concerned more than 1.6 million subjects taking a look at the advantages of green tea.
The review finds 'limited' evidence that the green variety of tea offers any protective benefits... Though it remains a natural, savory drink just the same.
Green tea comes from the same plant, Camellia sinensis, as black and oolong teas - each type is formed using different processing methods, and all forms are sometimes brewed and drunk as a drink.
Tea extracts can be taken in capsules, or you may find them in skin care creams. Tea is safe for most people if you drink it carefully, though it does have some caffeine ( not without its own complications ), and a bit of vitamin K ( an argument if you're taking anticoagulants like warfarin ) per cup.
There's been a lot of studies over time on tea of the green kind and its advantages to the body, and some evidence that usual drinkers do have lower risks of heart problems and maybe even some kinds of cancer.
In China this delicious beverage is often used to treat illnesses like headaches and depression. There are masses of sorts of tea grown in places all over the world, which allows for natural differences in taste and color due to growing conditions, harvesting and the kind of processing.
The team of researchers who conducted the newest work evaluated existing scientific literature on the green variety of tea - drinking or taking extracts - and identified 51 suitable studies.
27 of them were case-control studies, 23 cohort studies and one ( on prostate cancer ) a random controlled trial, the gold standard of clinical evidence.
The studies looked at green tea consumption and carcinoma of the digestive tract, gynecological cancers including breast cancer, urological cancer including prostate problems, lung cancer and cancer of the mouth. The research used were judged to be of medium to high methodological quality.
When it comes to stomach cancers and this kind of tea the results were 'highly contradictory'. Boehm and the team found 'limited evidence' in terms of liver cancer risk and conflicting evidence on digestive cancers.
Evidence for bladder and lung cancers was 'limited to moderate', with a discovery that green tea might really increase the danger of bladder cancer. Green tea appeared to give no protection for stomach cancers, with results called 'moderate to strong' by the researchers.
Green tea salvages its good-for-you reputation when it comes to prostate trouble. Studies that are considered better quality do support a link between green tea ( in drink or extract ) and lower risk of disease.
At best, right now the connection between green tea and cancer remains unproven though you could have heard report of the research that link green tea to some amazing health benefits.
Benefits like improving heart health, lowering high cholesterol, reducing the damage due to free radicals, stopping the unnatural formation of blood clots as well as reducing the progression of cognitive impairment and Alzheimer's illness.
Additional research is needed - a large, carefully designed research that involves subjects who actually drink enough tea as part of their daily consumption.
Of course such work takes a lot of time and expensive - nonessential if you're drinking tea for the taste and refreshment of it.
At intakes of five to 6 cups a day ( about 1,200 milliliters ) it is a safe, exquisite drink and although the advantages of green tea haven't been unconditionally confirmed, there is still evidence to show it helps with some conditions. - 17273
