Benefits of Green Tea

Kris Gunnars BSc writes:
"Green tea is the healthiest beverage on the planet.
It is loaded with antioxidants and nutrients that have powerful effects on the body.
These include improved brain function, fat loss, a lower risk of cancer and many other impressive benefits.

Below are 10 health benefits of green tea that are supported by studies.

Green Tea Contains Bioactive Compounds That Improve Health
Green tea is more than just liquid.
Many of the plant compounds in the tea leaves do make it into the final drink, which contains large amounts of important nutrients. Tea is rich in polyphenols that have effects like reducing inflammation and helping to fight cancer. Green tea also has small amounts of minerals that are important for health. Try to choose a higher quality brand of green tea, because some of the lower quality brands can contain excessive amounts of fluoride. That being said, even if you choose a lower quality brand, the benefits still far outweigh any risk.
Summary Green tea is loaded with polyphenol antioxidants, including a catechin called EGCG. These antioxidants can have various beneficial effects on health.

Compounds in Green Tea Can Improve Brain Function and Make You Smarter

Green tea does more than just keep you awake, it can also make you smarter. The key active ingredient is caffeine, which is a known stimulant. It doesn't contain as much as coffee, but enough to produce a response without causing the "jittery" effects associated with too much caffeine. Many people report having more stable energy and being much more productive when they drink green tea, compared to coffee.
Summary Green tea contains less caffeine than coffee, but enough to produce an effect. It also contains the amino acid L-theanine, which can work synergistically with caffeine to improve brain function.

Green Tea Increases Fat Burning and Improves Physical Performance
Summary Green tea has been shown to boost the metabolic rate and increase fat burning in the short term, although not all studies agree.

Antioxidants in Green Tea May Lower Your Risk of Some Types of Cancer

Cancer is caused by uncontrolled growth of cells. It is one of the world's leading causes of death. It is known that oxidative damage contributes to the development of cancer and that antioxidants may have a protective effect. Green tea is an excellent source of powerful antioxidants, so it makes sense that it could reduce your risk of cancer, which it appears to do:
Breast cancer: A meta-analysis of observational studies found that women who drank the most green tea had a 20-30% lower risk of developing breast cancer, the most common cancer in women.
Prostate cancer: One study found that men drinking green tea had a 48% lower risk of developing prostate cancer, which is the most common cancer in men.
Colorectal cancer: An analysis of 29 studies showed that those drinking green tea were up to 42% less likely to develop colorectal cancer.
Many observational studies have shown that green tea drinkers are less likely to develop several types of cancer. However, more high-quality research is needed to confirm these effects. It is important to keep in mind that it may be a bad idea to put milk in your tea, because some studies suggest it reduces the antioxidant value.
Summary Green tea has powerful antioxidants that may protect against cancer. Multiple studies show that green tea drinkers have a lower risk of various types of cancer.

Green Tea May Protect Your Brain in Old Age, Lowering Your Risk of Alzheimer's and Parkinson's
Not only can green tea improve brain function in the short term, it may also protect your brain in old age. Alzheimer's disease is the most common neurodegenerative disease in humans and a leading cause of dementia.
Parkinson's disease is the second most common neurodegenerative disease and involves the death of dopamine producing neurons in the brain. Multiple studies show that the catechin compounds in green tea can have various protective effects on neurons in test tubes and animal models, potentially lowering the risk of Alzheimer's and Parkinson's.
Summary The bioactive compounds in green tea can have various protective effects on the brain. They may reduce the risk of both Alzheimer's and Parkinson's, the two most common neurodegenerative disorders.

Green Tea Can Kill Bacteria, Which Improves Dental Health and Lowers Your Risk of Infection
Summary The catechins in green tea may inhibit the growth of bacteria and some viruses. This can lower the risk of infections and lead to improvements in dental health, a lower risk of caries and reduced bad breath.

Green Tea May Lower Your Risk of Type 2 Diabetes
Type 2 diabetes is a disease that has reached epidemic proportions in the past few decades and now afflicts about 400 million people worldwide. This disease involves having elevated blood sugar levels in the context of insulin resistance or an inability to produce insulin.
Summary Some controlled trials show that green tea can cause mild reductions in blood sugar levels. It may also lower the risk of developing type 2 diabetes.

Green Tea May Reduce Your Risk of Cardiovascular Disease
Cardiovascular diseases, including heart disease and stroke, are the biggest causes of death in the world. Studies show that green tea can improve some of the main risk factors for these diseases.
Summary Green tea has been shown to lower total and LDL cholesterol, as well as protect the LDL particles from oxidation. Observational studies show that green tea drinkers have a lower risk of cardiovascular disease.

Green Tea Can Help You Lose Weight and Lower Your Risk of Obesity
Summary Some studies show that green tea leads to increased weight loss. It may be particularly effective at reducing the dangerous abdominal fat.

Green Tea May Help You Live Longer

Of course, we all have to die eventually. That is inevitable. However, given that green tea drinkers are at a lower risk of cardiovascular disease and cancer, it makes sense that it could help you live longer.
In a study of 40,530 Japanese adults, those who drank the most green tea (5 or more cups per day) were significantly less likely to die during an 11 year period:
Death of all causes: 23% lower in women, 12% lower in men.
Death from heart disease: 31% lower in women, 22% lower in men.
Death from stroke: 42% lower in women, 35% lower in men.
Another study in 14,001 elderly Japanese individuals aged found that those who drank the most green tea were 76% less likely to die during the 6 year study period.
Summary Studies show that green tea drinkers are likely to live longer than non-tea drinkers.

The Bottom Line
In order to feel better, lose weight and lower your risk of chronic diseases, then you might want to consider making green tea a regular part of your life."

I don't drink any hot drinks on a regular basis, though I have started drinking tea more often than I ever have done in the past. Green tea is something I've never tried though, but I have got a few sachets to try. I do hope I like it after reading about all these benefits.

Hello Grace
That's a good question, if you think that the best source of hydration is still water, green tea makes it easy to hydrate with more flavour, without the calories and sugar found in some other drinks, like juice. In general, women need about 9 cups of beverages daily, while men need about 13 cups, and drinking green tea can help you get there.

I am not a medical person, but looking around various articles there doesn't seem to be any specific intake guideline for green tea, and even research into green tea's benefits doesn't paint a clear picture of exactly how much you should drink each day.

However, if you are drinking lots of green tea daily, stay mindful that it does contain caffeine—up to 63 milligrams per cup. Drinking more than 10 cups of green tea daily might have side effects due to caffeine consumption, especially if you have an underlying condition, like liver disease or heart problems.

Also, if you are sensitive to caffeine or suffer from insomnia, more than four cups of green tea will be too much for your system, regardless of the benefits.

For women trying to get pregnant or are pregnant, you should definitely limit your green tea consumption to two cups a day... perhaps skip it altogether.

Do not sip green tea with meals as it may interfere with absorption of iron in your body.

Having said all that, for the most part, though, any moderate consumption is probably fine – so grab a cup or mug and drink up.

The details above were taken from articles on these two links below:

I hope the information helps you decide how many cups you feel happy drinking ...

All the best Jan

Thank you for this excellent article, I will definitely be drinking more green tea...

klahanie said...

Time for some green tea. I drink green tea fairly often. Makes for an improvement over the other green tea I tried. That green tea turned out to be a mouldy tea bag. Not good.

Thanks for this informative article.
