Benefits Of Green Tea
Benefits Of Green Tea
Green tea is without question the healthiest beverage on the planet.
It is full up with antioxidants and nutrients that have powerful effects on the body.
These include improved brain function, fat loss, and weight control, a lower risk of some cancers and many other wonderful benefits.
Below are 10 health benefits of green tea that are supported by studies.
Green tea is more than just fluid.
Many of the plant compounds in the tea leaves make it into the fully brewed drink, which contains large amounts of important nutrients
Tea is rich in polyphenols that have effects like reducing inflammation and helping to fight some cancers.
Green tea is about 30 percent polyphenols by weight, including large amounts of a catechin called EGCG. Catechins are natural antioxidants that help prevent cell damage and provide other benefits.
These substances can help substantially 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 associated with age.
EGCG (Epigallocatechin Gallate) is one of the most powerful compounds in green tea. It has been studied to treat various diseases and may be one of the main reasons green tea has such powerful medicinal properties
Green tea also has small amounts of minerals that are important for health.
Try to choose our higher quality brand of green tea, because some of the lower quality cheaper brands can contain excessive amounts of fluoride
If you look at the ingredients list for any fat burning diet help, chances are that green tea will be on there.
This is because green tea has been shown to increase fat burning capability and a boost in the metabolical 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.
However, some studies on green tea don't show any increase in metabolism, so the effects may depend on the individual.
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.
Green tea does more than just keep you awake, it can also make you smarter.
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
Green tea contains more than just caffeine. It also has the amino acid L-theanine, which is able to cross the blood-brain barrier
L-theanine increases the activity of the inhibitory neurotransmitter GABA, which has an anty anxiety effect. It also helps increases dopamine and the production of alpha waves in the brain
The latest studies show that caffeine and L-theanine can have synergistic effects. The combination of the two is particularly potent at improving brain function.
Because of the L-theanine and the smaller dose of caffeine, green tea can give you a much milder and different kind of boost than coffee.
Many people report having more stable energy levels and being much more productive at work and home when they drink green tea, compared to coffee.
4. Antioxidants in Green Tea May Lower Your Risk of Some Types of Cancer But More Research Would Be Needed.
Studies on green tea’s impact on some cancers have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some instances that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's website says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer let us be very clear on this.
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 help reduce your risk of some 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, a lot more high-quality research is needed to confirm these effects this is by no way a cure in any form for cancer.
Not only can green tea help improve brain function in the shorter term, it may also protect your brain in your old age.
Alzheimer's disease is the most common neurodegenerative disease in humans and a leading cause of dementia and seems to be on the increase.
Parkinson's disease is the second most common neurodegenerative disease and involves the death of dopamine-producing neurons in the brain.
Many 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.
6. Green Tea Can Kill Some Bacteria In The Mouth, Which Improves Dental Health and Lowers Your Risk of Infection.
The catechins in green tea also have other biological effects.
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.
Many studies also show that green tea can reduce 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.
Studies show that green tea can improve insulin sensitivity and achieve reduced blood sugar level.
One study in Japanese individuals found that those who drank the most green tea had a 42% lower risk of developing type 2 diabetes.
According to a recent review of 7 studies with a total of 286,701 individuals, green tea drinkers had an 18% lower risk of becoming diabetic.
Cardiovascular diseases, including heart disease and stroke, are the biggest causes of death in the world at this time.
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 capacity of the blood, which protects the LDL particles from oxidation, which is one part of the pathway towards heart disease.
Now we understand the beneficial effects on risk factors, it is not a surprise to see that green tea drinkers have up to a 31% lower risk of cardiovascular disease.
Yes its true that green tea can boost the metabolic rate in the short term, it makes perfect sense that it will help you lose weight.
Lots of studies show that green tea leads to a decrease in body fat, especially in the abdominal or tummy area.
One of these studies was a 12-week randomized controlled trial in 240 men and women. In this study, the green tea group had significant decreases in body fat percentage, body weight, waist, and belly fat.
10. Better General Health In Your Lifetime
We all want to live longer right ?, But we all have to die eventually. That is inevitable.
But given that green tea drinkers are at a lower risk of cardiovascular disease and some cancers, it makes good 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 in a 24 hour day were significantly less likely to die during an 11 year time 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.
Also a 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 time period.
