Can Green Tea Prevent Heart Disease

What is Green Tea Extract?

Some data suggests that green tea can reduce the risk of cardiovascular diseasea narrowing of the arteries that can lead to heart attack, chest pains, or stroke.

For example, in a study of more than 40,500 adults, researchers in Japan found that those who consumed five or more cups of green tea per day were 26 percent less likely to die of cardiovascular disease over an 11-year period than those who drank just one cup per day.

Similarly, a study of 76,979 people published in the Journal of Epidemiology and Community Health in 2011 found that women who drank one to six cups of green tea per day had a reduced risk of dying of cardiovascular disease compared with those who drank none.

How might green tea protect the heart? Experts say it may reduce high cholesterol levels and high blood pressure, which are important factors in cardiovascular disease.

But while this is a potential benefit, it’s not conclusive, and high doses of green tea can reduce the effectiveness of the drug nadolol, used to treat high blood pressure and heart problems, cautions NIH.

To reduce your risk of diseases such as cancer and heart disease , he says, you need to eat a healthy diet that includes plenty of fruit, vegetables, and whole grains. You should also exercise and avoid smoking.

Does Green Tea Prevent Cancer

Compounds called catechins are often credited for green teas cancer-fighting potential. These antioxidants have the ability to block the action of molecules called free radicals, which can cause changes in healthy cells that sometimes lead to cancer. But theres no solid proof yet that the catechins in green tea help to prevent cancer in humans, despite some promising studies in test tubes and animals.

In 2009 the Cochrane Library published a review of 51 studies that included a total of more than 1.6 million participants. Each study investigated whether consuming green tea reduced the risk of developing specific types of cancer, including those of the breast, colon, oral cavity, liver, pancreas, and prostate.

The results were conflicting, says lead author Katja Boehm, PhD, a health psychologist at Private University Witten/Herdecke in Germany. After scrutinizing the data, Boehm says, the evidence of a benefit wasnt strong enough to recommend using green tea to protect against cancer.

In a 2020 update to that review, the authors concluded that the evidence for a beneficial effect against cancer remains limited, with inconsistent results between studies.

What About Green Tea Extracts Other Benefits

Studies of green tea extracts effect on athletic performance have been inconclusive. But enjoying a cup of green tea after a workout is a great way to hydrate, and load your body with antioxidants and nutrients, adds Dr. Todorov.

And research on green tea extract for weight loss has found it has minimal, if any, effect. In my opinion, patients can achieve the same amount of weight loss with lifestyle changes, and avoid the risk of side effects and the cost of supplements, says Dr. Todorov.

However, drinking green tea itself is associated with a lower risk of coronary artery disease. A meta-analysis found that consuming green tea or green tea extract with 150 to 2500 milligrams of catechins daily improved patients cholesterol profiles.

Dr. Todorov also gives green tea a thumbs up for skin health because of its antioxidant properties.

Does Green Tea Help With Cancer

There havent been enough studies to prove that green tea can help with cancer risks.

Early studies show that green tea may help prevent the risk of cancer, but theres no reliable evidence.

There are many factors that can affect a study about cancer like lifestyle, amount of green tea taken, and other supplements or treatments that people were using.

Although the studies have been hopeful about preventing cancer risks, green tea is still considered a supplement to promote overall well-being and not cure any disease. Any disease like breast cancer should be treated with the help of medical professionals.

Green Tea Extract: The Health Benefits


Green Tea has been studied extensively over the past few decades, with human and animal studies both examining the relationship between Green Tea and health.

In Chinese medicine, Green Tea is often recommended for digestive issues, headaches and aches and pains. Below, we explain the great benefits associated with taking Green Tea Extract using supporting studies so you can be sure of its effects on the body.

The main health benefits of Green Tea Extract come from its high antioxidant content, known as polyphenols. There is substantial evidence that specific polyphenols may benefit health status, especially for the prevention and management of certain chronic diseases3.

Animal and human studies have shown that various polyphenols have antioxidant and anti-inflammatory properties that could prevent cardiovascular disease, neurodegenerative disorders, obesity and cancer4.

Clearly There’s Evidence Backing Up Those Green Tea Extract Weight Loss Claims You Might Have Seen Online Or At The Grocery Store But How Exactly Does It Work

The secret lies in green tea extract’s high concentration of antioxidants called catechins, which have been correlated with a reduction in body fat. Green tea extract’s high caffeine content also likely plays a role in its weight loss benefits. One study found that people who consumed high amounts of caffeine and green tea lost more weight and fat mass than those who consumed less of it. Other research, published in Food Science and Biotechnology, found that caffeine can actually signal the body to break down fat. So it’s likely that the caffeine and antioxidants work in tandem as a catalyst for weight loss.

When the green tea extract goes into the body, the antioxidants and caffeine enter the cells and help the body burn calories and fat, said Liana Werner-Gray, a health and nutrition coach who specializes in weight loss at Complete Wellness NYC. “Green tea extract is a good, natural way to lose weight. We have so many studies to back it up.”

If you’ve already got some matcha in your pantry, you might be wondering: Can I lose weight by drinking a cup of green tea instead of taking the extract? Not quite. Swapping out heavier drinks, like soda and lattes, for green tea can certainly help you cut calories, but beyond that, drinking tea instead of taking green tea extract probably won’t give you the weight loss results you’re looking for.

Effects On Antioxidant Markers And Oxidative Stress

Green tea is a popular neutraceutical as an antioxidant. Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species, such as singlet oxygen, superoxide, peroxyl radicals, hydroxyl radicals, and peroxynitrite. An imbalance between antioxidants and reactive oxygen species results in oxidative stress, leading to cellular damage . Catechins are hypothesized to help protect against these diseases by contributing, along with antioxidant vitamins and enzymes , to the total antioxidant defense system .

Pilipenko et al. assessed the tolerance of tableted green tea and its effect on the antioxidant status indices. Twenty-five patients with different gastrointestinal pathologies were included in the study and divided into treatment and control groups. The tolerance of tableted green tea was good in the treatment group, who showed better dynamics of quality-of-life indices, especially in scales of body pain and social functioning. There were no significant differences in biochemical analysis between the groups, which may indicate the safety of this product. Analysis revealed that the treatment group showed a decreased level of all antioxidant status indices, as reflected in a significant decreasing of the lipid peroxidation index from 4.63 to 4.14.

Matcha May Help Weight And Belly Fat Too

Green tea extract supplements and its benefits

Kirkpatrick gets a lot of questions from her clients on whether matcharemember thats the leaves ground up into powder formis as helpful as the green tea leaves that come in teabags or as loose tea. There havent been a ton of studies on matcha alone, she says. But adds that its reasonable to think its just as useful, as green tea is made of the leaves of the plant, and matcha is made of the ground-up plants.

While numerous studies have looked at green tea extracts taken as supplements, Kirkpatrick urges people to get their green tea from the actual tea itself in the most whole form possible.

Green Tea & Prostate Cancer: Implications

Prostate cancer is typically a slow-growing cancer, Henning says. That makes it an ideal cancer to try diet interventions to slow it even more.

âGreen tea is high in polyphenols and itâs convenient,â she says.

Other research has found that green tea may slow prostate cancer. An Italian study found that men who had a precursor to prostate cancer and drank green tea were less likely to get prostate cancer, Henning says.

Now, Henning is studying whether adding quercetin, an antioxidant found in apples and onions, to the green tea will ramp up its cancer-fighting ability.

Sumanta Pal, MD, assistant professor of medical oncology at the City of Hope Comprehensive Cancer Center in Duarte, Calif., reviewed the study findings for WebMD.

âStudies such as this are critical to confirm or support a plausible explanation for how green tea may work,â he says. More study is needed, however, before making any diet recommendations.

Import Of Radioactive Japanese Tea


On 17 June 2011, at Charles de Gaulle airport in Paris, France, radioactivecesium of 1,038 becquerels per kilogram was measured in tea leaves imported from Shizuoka Prefecture, Japan as a result of the Fukushima Daiichi nuclear disaster on 11 March, which was more than twice the restricted amount in the European Union of 500 becquerels per kilogram. The government of France announced that they rejected the leaves, which totaled 162 kilograms .

In response, the governor of Shizuoka Prefecture, Heita Kawakatsu, stated: “there is absolutely no problem when they drink them because it will be diluted to about 10 becquerels per kilogram when they steep them even if the leaves have 1,000 becquerels per kilogram ” a statement backed by tests done in Shizuoka. Japanese Minister for Consumer Affairs and Food Safety Renh stated on 3 June 2011 that “there are cases in which aracha are sold as furikake and so on and they are eaten as they are, therefore we think that it is important to inspect tea leaves including aracha from the viewpoint of consumers’ safety.”

In 2018, the US Food and Drug Administration updated its import status on Japanese products deemed to be contaminated by radionuclides, indicating that tea from the Ibaraki prefecture had been removed from the list by the Government of Japan in 2015.
