1. Green Tea Contains Various Bioactive Compounds That Can Improve Health

Green tea is more than just green liquid.

Many of the bioactive compounds in the tea leaves do make it into the final drink, which contains large amounts of important nutrients.

It is loaded with polyphenols like flavonoids and catechins, which function as powerful antioxidants.

These substances can reduce the formation of free radicals in the body, protecting cells and molecules from damage. These free radicals are known to play a role in aging and all sorts of diseases.

Green tea also has small amounts of minerals that are important for health.

Bottom Line: Green tea is loaded with bioactive compounds that can have various beneficial effects on health.

2. 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.

Caffeine has been intensively studied before and consistently leads to improvements in various aspects of brain function, including improved mood, vigilance, reaction time and memory.

However… green tea contains more than just caffeine. It also has the amino acid L-theanine, which is able to cross the blood-brain barrier.

Studies show that caffeine and L-theanine can have synergistic effects. The combination of the two is particularly potent at improving brain function.

Many people report having more stable energy and being much more productive when they drink green tea, compared to coffee.

Bottom Line: 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.

3. Green Tea Increases Fat Burning and Improves Physical Performance

If you look at the ingredients list for any fat burning supplement, chances are that green tea will be on there.

This is because green tea has been shown to increase fat burning and boost the metabolic rate, in human controlled trials.

In one study in 10 healthy men, green tea increased energy expenditure by 4%.

Another study showed that fat oxidation was increased by 17%, indicating that green tea may selectively increase the burning of fat.

Bottom Line: Green tea has been shown to boost the metabolic rate and increase fat burning in the short term, although not all studies agree.

4. Antioxidants in Green Tea May Lower Your Risk of Various Types of Cancer

Cancer is caused by uncontrolled growth of cells. It is one of the world’s leading causes of death.

It is well known that oxidative damage contributes to the development of cancer and that antioxidants can have a protective effect.

Green tea is an excellent source of powerful antioxidants, so it makes perfect sense that it could reduce your risk of cancer, which it appears to do.

Multiple other observational studies show that green tea drinkers are significantly less likely to get various types of cancer.

It is important to keep in mind that it may be a bad idea to put milk in your tea, because it can reduce the antioxidant value.

Bottom Line: 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.

5. 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.

Multiple studies show that the catechin compounds in green tea can have various protective effects on neurons in test tubes and animal models, potentally lowering the risk of Alzheimer’s and Parkinson’s.

Bottom Line: The bioactive compounds in green tea can have various protective effects on neurons and may reduce the risk of both Alzheimer’s and Parkinson’s, the two most common neurodegenerative disorders.

6. Green Tea Can Kill Bacteria, Which Improves Dental Health and Lowers Your Risk of Infection

The catechins in green tea have other biological effects as well.

Some studies show that they can kill bacteria and inhibit viruses like the influenza virus, potentially lowering your risk of infections.

Studies show that the catechins in green tea can inhibit the growth of streptococcus mutans. Green tea consumption is associated with improved dental health and a lower risk of caries.

Another awesome benefit of green tea… multiple studies show that it can reduce bad breath.

Bottom Line: 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.

7. Green Tea May Lower Your Risk of Type II Diabetes

Studies show that green tea can improve insulin sensitivity and reduce blood sugar levels.

One study in Japanese individuals found that those who drank the most green tea had a 42% lower risk of developing type II diabetes.

According to a review of 7 studies with a total of 286,701 individuals, green tea drinkers had an 18% lower risk of becoming diabetic.

Bottom Line: Some controlled trials show that green tea can cause mild reductions in blood sugar levels. It may also lower the risk of developing type II diabetes in the long term.

8. 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.

Given the beneficial effects on risk factors, it is not surprising to see that green tea drinkers have up to a 31% lower risk of cardiovascular disease.

Bottom Line: 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.

9. Green Tea Can Help You Lose Weight and Lower Your Risk of Becoming Obese

Given that green tea can boost the metabolic rate in the short term, it makes sense that it could help you lose weight.

Several studies show that green tea leads to decreases in body fat, especially in the abdominal area.

One of these studies was a randomized controlled trial in 240 men and women that went on for 12 weeks. In this study, the green tea group had significant decreases in body fat percentage, body weight, waist circumference and abdominal fat.

However, some studies don’t show a statistically significant increases in weight loss with green tea, so this needs to be taken with a grain of salt.

Bottom Line: Some studies show that green tea leads to increased weight loss. It is particularly effective at reducing the dangerous abdominal fat.

10. Green Tea May Help You Live Longer

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:

Another study in 14,001 elderly Japanese individuals aged 65-84 years found that those who drank the most green tea were 76% less likely to die during the 6 year study period .
