Green tea has increasingly become a very popular drink worldwide because of its immensely powerful health benefits. It is extraordinarily amazing what green tea
can do for your health.
Green tea is the healthiest beverage on the planet. It is loaded with antioxidants and nutrients that have powerful effects on the body. This includes improved brain function, fat loss, a lower risk of cancer and many other incredible benefits.
Here are 10 health benefits of green tea that have been confirmed in human research studies.
#1: Green Tea and 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 women 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.
- Colorectal cancer: A study of 69,710 Chinese women found that green tea drinkers had a 57% lower risk of colorectal cancer.
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.
#2: Green Tea and Skin
The antioxidant in green tea protects the skin from the harmful effects of free radicals, which cause wrinkling and skin aging. Green tea also helps fight against skin cancer.
#3: Green Tea and Heart 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.
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.
#4: Green Tea and Weight Loss
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.
#5: Green Tea and Anti-Aging
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 65-84 years found that those who drank the most green tea were 76% less likely to die during the 6 year study period.
#6: Green Tea and High Blood Sugar
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.
#6: Green Tea and High Blood Pressure
Green tea helps prevent high blood pressure. Drinking green tea helps keep your blood pressure down by repressing angiotensin, which leads to high blood pressure.
#7: Green Tea and Arthritis
Green tea can help prevent and reduce the risk of rheumatoid arthritis. Green tea has benefit for your health as it protects the cartilage by blocking the enzyme that destroys cartilage.
#8: Green Tea and 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 as well.
#9: Green Tea and Cholesterol
Green tea can help lower cholesterol level. It also improves the ratio of good cholesterol to bad cholesterol, by reducing bad cholesterol level.
#10: Green Tea and Old Age Illnesses
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, potentally lowering the risk of Alzheimer’s and Parkinson’s.
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.
