Green tea and cancer -

However, results according to the type of cancer and study design were inconsistent. What are the conclusions? A beneficial effect of green tea consumption on cancer prevention remains unproven so far. Caution is advised regarding supplementation with high-dose green tea extracts due to the possible adverse effects.

Overall, findings from experimental and nonexperimental epidemiological studies yielded inconsistent results, thus providing limited evidence for the beneficial effect of green tea consumption on the overall risk of cancer or on specific cancer sites. Some evidence of a beneficial effect of green tea at some cancer sites emerged from the RCTs and from case-control studies, but their methodological limitations, such as the low number and size of the studies, and the inconsistencies with the results of cohort studies, limit the interpretability of the RR estimates.

The studies also indicated the occurrence of several side effects associated with high intakes of green tea. In addition, the majority of included studies were carried out in Asian populations characterised by a high intake of green tea, thus limiting the generalisability of the findings to other populations.

Well conducted and adequately powered RCTs would be needed to draw conclusions on the possible beneficial effects of green tea consumption on cancer risk. This review is an update of a previously published review in the Cochrane Database of Systematic Reviews , Issue 3. Tea is one of the most commonly consumed beverages worldwide.

Teas from the plant Camellia sinensis can be grouped into green, black and oolong tea, and drinking habits vary cross-culturally. C sinensis contains polyphenols, one subgroup being catechins.

Catechins are powerful antioxidants, and laboratory studies have suggested that these compounds may inhibit cancer cell proliferation. Some experimental and nonexperimental epidemiological studies have suggested that green tea may have cancer-preventative effects.

To assess possible associations between green tea consumption and the risk of cancer incidence and mortality as primary outcomes, and safety data and quality of life as secondary outcomes. We searched eligible studies up to January in CENTRAL, MEDLINE, Embase, ClinicalTrials.

gov, and reference lists of previous reviews and included studies. We included all epidemiological studies, experimental i. randomised controlled trials RCTs and nonexperimental non-randomised studies, i. observational studies with both cohort and case-control design that investigated the association of green tea consumption with cancer risk or quality of life, or both.

Two or more review authors independently applied the study criteria, extracted data and assessed methodological quality of studies.

We summarised the results according to diagnosis of cancer type. In this review update, we included in total completed studies 11 experimental and nonexperimental and two ongoing studies.

This is an additional 10 experimental and 85 nonexperimental studies from those included in the previous version of the review. Eleven experimental studies allocated a total of participants to either green tea extract or placebo, all demonstrating an overall high methodological quality based on 'Risk of bias' assessment.

For incident prostate cancer, the summary risk ratio RR in the green tea-supplemented participants was 0. The summary RR for gynaecological cancer was 1. No evidence of effect of non-melanoma skin cancer emerged summary RR 1.

Green tea is known to have several benefits for the body. It can increase fat burning, improve brain function, and lead to a longer and healthier life. People with cancer often use green tea because of its antioxidant properties.

Especially for breast cancer patients, green tea is a popular supplement that people take alongside their cancer treatment. Green tea has its origins in China and is popular across Asian countries like Japan and India. It is made from unfermented leaves of the Camellia sinensis plant.

Traditional eastern doctors used green tea to treat gas, regulate body temperature, promote good digestion, and improve overall health.

Green tea contains a strong concentration of antioxidants that are thought to promote health. Another substance in green tea that researchers think is the most effective is a type of catechin called epigallocatechingallate EGCG. Green tea also contains caffeine and theanine. There is no specific evidence that green tea is effective in treating cancer.

However, evidence shows that green tea may reduce the risk of developing certain cancers in people. Preliminary studies have also shown that green tea is effective in stopping the growth of cancer cells in some animals. Green tea has positive benefits on overall health, which is one reason that many breast cancer patients drink it.

Other reasons that people with cancer choose to drink green tea include the following beliefs:. Similar to other teas, green tea normally comes in pre-made bags or loose leaves.

Many people prefer loose leaf tea for improved taste and purity. To perfectly brew green tea, you should steep it in water boiled to ° Fahrenheit for two-to-three minutes. In terms of how often you should drink green tea to reap its benefits, manufacturers recommend having between three and five cups every day.

Eight ounces of brewed green tea contains about 28 mg of caffeine eight ounces of coffee contains 95mg. Therefore, green tea will keep you awake if you drink it close to bedtime. While some decaffeinated green teas are available, it is unknown whether removing caffeine would also remove any possible health benefits.

ECGC, one substance in green tea that is thought to provide health benefits, is available as a green tea extract that people can take in liquid, tablet, or capsule supplements. You should ensure that whatever green tea you are taking is safe and certified.

Green tea usually is safe to drink, but you should be cautious about consuming large amounts of caffeine. Too much caffeine can lead to difficulty sleeping, headaches, and feeling jittery or shaky.

Additionally, large amounts of EGCG can cause some people to experience sickness or stomach aches. Particularly large quantities can be toxic to the liver. EGCG can also reduce the effects of other medications.
