In order to feel better, lose weight and lower your risk of chronic diseases, you might want to consider making green tea a regular part of your life.
Below are 10 health benefits of green tea that are supported by studies.
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 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.
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.
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:
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, potentially lowering the risk of Alzheimer's and Parkinson's.
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.
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 2 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.
Cardiovascular diseases, including heart disease and stroke, are the biggest causes of death in the world.
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.
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 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 circumference and belly fat.
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:
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.
