Practical Tips For Buying Green Tea For Cancer Prevention

Green tea, also known as Chinese tea, is a type of tea made from Camellia sinensis leaves. Aside from water, it is the most widely consumed beverage around the world. Because of its popularity, researchers and consumers have been fascinated with potential health outcomes associated with drinking green tea. Epidemiological studies suggest that the consumption of green tea may help prevent cancers in humans. In various parts of Asia it has been used as a medicine for many years. The tea is made from the steamed, unfermented leaves of the Camellia sinensis plant. It is also called Chinese tea.

Health benefit of drinking green tea:

Some studies found that consuming green tea lowered both LDL, or ‘bad’, cholesterol and triglycerides, a type of fat found in blood. LDL cholesterol and triglycerides both contribute to fatty build-ups in arteries. These build-ups are often associated with strokes, heart attacks, and peripheral artery disease (PAD). As green tea was found to reduce these build-ups, researchers concluded that drinking this tea could lower the risk of cardiovascular diseases. Studies have also found that green tea may lower one’s risk of obesity and improve physical performance. Drinking four cups of green tea a day for two months caused a significant decrease in body weight, body mass index (BMI), waist circumference, and systolic blood pressure.

Green tea and cancer: 

Tea has long been regarded as an aid to good health, and many believe it can help reduce the risk of cancer. Some laboratory studies have shown that extracts from green tea can stop cancer cells from growing. Most studies of tea and cancer prevention have focused on green tea. Although tea and/or tea polyphenols have been found in animal studies to inhibit tumorigenesis at different organ sites, including the skin, lung, oral cavity, esophagus, stomach, small intestine, colon, liver, pancreas, and mammary gland, the results of human studies—both epidemiologic and clinical studies—have been inconclusive. 

Practical tips for buying green tea for cancer prevention 

Green tea contains substances called polyphenols. A subgroup of these polyphenols is called catechins. Scientists think catechins give green tea its antioxidant properties. The catechin in green tea is called epigallocatechin-3-gallate (EGCG). Researchers think that EGCG has an anti-tumour (anti-cancer) effect. So before buying green tea for cancer prevention, you must ensure that it must contain catechin. 

Lab results on cancer prevention 

Lab results are encouraging. But we need evidence from human studies to prove them. The evidence at the moment from human studies is mixed. Researchers published an overview of studies (a meta analysis) in 2014. It suggested that green tea could reduce the risk of developing mouth cancers.

Other studies have shown it may reduce the risk of developing:

  • Lung cancer
  • Bladder cancer
  • Cancer of the food pipe (esophagus).

Breast cancer

In 2018 researchers did another review and meta analysis of several studies. It showed that green tea might help to prevent breast cancer. And that it might especially help to prevent breast cancer from coming back. But the studies in the review were small. The researchers said that we need more scientific studies looking at greater numbers of people.

Prostate cancer

The research looking at whether it prevents prostate cancer generally and in pre cancerous prostate cells is mixed with some showing it might and others not showing any evidence. But a review study in 2018 suggests that the substances in green tea in laboratory research and early clinical trials suggests it may be of benefit. They suggest we need more research. 

Bowel cancer

Researchers did a study in 2017 on 39 patients. It was on people at risk of colon and rectal cancer. They found that green tea did not reduce the amount of aberrant crypt foci (ACF). ACF are groups of abnormal tube-like glands in the lining of the colon and rectum. They are early changes in the colon and rectum and can lead to cancer.

How to use it:

Green tea  comes as ready-made tea bags or leaves. You add boiling water to it.

There are different views on how many cups you should drink each day to get a possible benefit.  In general, it is suggested to have between 3 and 5 cups of tea per day.

Most green teas contain caffeine. So, it will act as a stimulant and keep you awake if you drink it before going to bed. Decaffeinated green tea is also available in the market. It is uncertain whether removing the caffeine could reduce the possible antioxidant effects.

EGCG, the helpful substance in green tea, is available as green tea extract. People take it as a supplement in liquids, tablets or capsules.

Green tea is also sold as a herbal supplement in most countries. So, manufacturers don’t have to prove that they are safe or even that they have any health benefits.

This means that the product or dose might not have been through tests to see if it works. Keep this in mind when buying supplements.
