The Confusing Reports on Cancer And Green Tea
If you are drinking green tea only for the disease protection, you may be interested in the results of a systematic review of studies that involved more than 1.6 million subjects looking at the advantages of green tea.
The review finds ‘limited’ proof that the green variety of tea offers any protecting benefits… Though it remains a natural, savory beverage 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 usually brewed and drunk as a beverage.
Tea extracts can also taken in capsules, or you can find them in skin care products. Tea is safe for the majority if you drink it sparsely, though it does have some caffeine ( not without its own side effects ), and a touch of vitamin K ( a controversy if you are taking anticoagulants like warfarin ) per cup.
There’s been lots of studies over time on tea of the green kind and its advantages to the body, and some evidence that regular drinkers do have lower risks of heart problems and perhaps even some forms of cancer.
In China this mouth-watering beverage is routinely used to treat ailments like headaches and depression. There are a lot of sorts of tea grown in places all over the globe, which allows for natural differences in taste and color due to growing conditions, cropping and the type of processing.
The team of analysts who carried out the latest work looked over existing scientific literature on the green range of tea – drinking or taking extracts – and identified 51 acceptable studies.
Twenty-seven of them were case-control studies, twenty-three cohort studies and one ( on prostate cancer ) a random controlled trial, the gold standard of clinical trials.
The studies assessed green tea consumption and carcinoma of the digestive system, 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 digestive cancers and this type of tea the results were ‘highly contradictory’. Boehm and the team found ‘limited evidence’ vis liver cancer risk and clashing evidence on digestive cancers.
Proof for bladder and lung cancers was ‘limited to moderate’, with a discovery that green tea might really increase the risk of bladder cancer. Green tea appeared to give no protection for stomach cancers, with results called ‘moderate to strong’ by the team.
Green tea proves its good-for-you reputation when it comes to prostate trouble. Studies that are thought to be better quality do support a link between green tea ( in libation or extract ) and lower risk of disease.
At best, at the moment the link between green tea and cancer remains unproven though you’ll have heard report of the research that link green tea to some impressive health benefits.
Benefits like better heart health, lowering high cholesterol, reducing the damage caused by free radicals, stopping the unnatural formation of blood clots as well as slowing the progression of cognitive impairment and Alzheimer’s illness.
More research is needed – a giant, 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 are drinking tea for the taste and refreshment of it.
At intakes of 5 to 6 cups a day ( about 1,200 milliliters ) it is a safe, exquisite libation and though the advantages of green tea have not been completely confirmed, there’s still evidence to show it helps with some conditions.
