Hi~ We’re in the 3rd weeks of April, right now..
And well ya, i’m suprised that i’m still here in Jakarta.
I got a little addiction with green tea. I like the taste of green ‘tea’.. a real green tea.
Now i’m leaving coffee for a tea. What an unexpected fact that i can do this..
Green tea or Teh Hijau is made from the leaves from Camellia sinensis that have undergone minimal oxidation during processing. Green tea originated in China, but it has become associated with many cultures throughout Asia. Green tea has recently become relatively widespread in the West where black tea has been the traditionally consumed tea. Wikipedia
And the most important things, the benefits of green tea are:
- 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.
One of the more powerful compounds in green tea is the antioxidant Epigallocatechin Gallate (EGCG), which has been studied to treat various diseases and may be one of the main reasons green tea has such powerful medicinal properties.
Bottom Line: Green tea is loaded with bioactive compounds that can have various beneficial effects on health
- Coumpounds 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 knownstimulant.
It doesn’t contain as much as coffee, but enough to produce a response without causing the “jittery” effects associated with too much caffeine.
What caffeine does in the brain is to block an inhibitory neurotransmitter called Adenosine. This way, it actually increases the firing of neurons and the concentration of neurotransmitters like dopamine and norepinephrine.
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
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.
- Green tea increase fat burning and improves physical performance.
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.
Caffeine itself has also been shown to improve physical performance by mobilizing fatty acids from the fat tissues and making them available for use as energy.
In two separate review studies, caffeine has been shown to increase physical performance by 11-12%, on average.
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.
- Antioxidants in Green Tea may lower you 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:
- Breast cancer: A meta-analysis of observational studies found that whomen who drank the most green tea had a 22% 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.
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.
- 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.
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.
- 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.
Streptococcus mutans is the primary harmful bacteria in the mouth. It causes plaque formation and is a leading contributor to cavities and tooth decay.
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.
- Green Tea may lover your risk of Type II Diabetes
Type II diabetes is a disease that has reached epidemic proportions in the past few decades and now afflicts about 300 million people worldwide.This disease involves having elevated blood sugar levels in the context of insulin resistance or an inability to produce insulin.
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.
- Green Tea may reduce your risk of Cardiovascular DiseaseCardiovascular 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.
This includes total cholesterol, LDL cholesterol and triglycerides.
Green tea also dramatically increases the antioxidant capability of the blood, which protects the LDL cholesterol particles from oxidation, which is one part of the pathway towards heart disease.
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.
- Green Tea can help you lose weight and lower you risk of becoming obese
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.
- Green Tea may decrease your risk of dying and 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.
So.. What do you think about green tea..?
