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.
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.
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.
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.
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.
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.
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.
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.
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."

If you may have any food allergies, or underlying health issues these must always be taken into account. If you are a diabetic and not sure how certain foods may affect your blood sugars, test is best, i.e. use your meter.
