The green tea is one of the healthiest drinks on the planet. In addition to its ability to function as a supplement in weight loss diets, green tea improves brain function, decreases the risk of cancer and much more.
1. Contains Bioactive Components That Improve Health:
Many of the bioactive components in tea leaves are transferred to the beverage, which contains large amounts of important nutrients. It is packed with polyphenols, such as 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. Free radicals play an essential role in the aging process and in the development of various diseases.
One of the most powerful components in green tea is an antioxidant called epigallocatechin gallate (EGCG), which has proven useful in the treatment of various diseases and is perhaps one of the main reasons behind the medicinal power of tea. In addition, this tea includes small amounts of minerals very important for health. It is important to choose prestigious brands when buying it, as some of lower quality may contain too high levels of fluoride.
In short: Green tea is full of bioactive components with several health benefits.
2. Improves Brain Function:
The key ingredient in green tea is caffeine. It does not contain as much as coffee, but enough to produce an organic response without the side effect of anxiety associated with its excess. What caffeine does to the brain is to block an inhibitory neurotransmitter called adenosine. In this way, it elevates neuronal impulses and the concentration of neurotransmitters such as dopamine and norepinephrine. Caffeine has already been studied intensively and was shown to lead to improvements in various aspects of brain functioning, including mood, alert levels, reaction time and memory. However, green tea contains more than just caffeine.
“It also includes the amino acid L-theanine, which has the ability to cross the blood-brain barrier”.
L-Theanine increases the activity of the GABA inhibitor neurotransmitter, which has anti-anxiety effects. At the same time, it increases the levels of dopamine and the production of alpha waves in the brain. In addition, some studies show that caffeine and L-theanine may have effects in synergy. The combination of both is particularly potent when it comes to improving brain function. Thus, in the hands of L-theanine and the lower dose of caffeine, it can provide a different, softer stimulus than coffee. Many people say that the effect results in more stable energy and higher productivity.
In short: Green tea contains less caffeine than coffee, but enough to cause effects. In addition, it contains the amino acid L-theanine, which can work in synergy with coffee to optimize brain function.
3. Elevates Fat Burning and Improves Physical Performance:
In several controlled studies in humans, green tea has been shown to increase fat burning and metabolism. In an investigation conducted in 10 healthy men, it increased energy expenditure by 4%. Another study showed that, by consuming it, fat oxidation rose by 17%. However, it is also important to underline that other studies on green tea showed no improvement in metabolism, so the effects may depend on the individual. Caffeine alone also works when it comes to improving physical performance, mobilizing fatty acids from tissues and making them available for use as energy. Thus, in two independent review studies, caffeine increased physical performance by 11 to 12% on average.
In short: It increases metabolism and fat burning in the short term, although not all studies agree on this point.
4. The Antioxidants in Green Tea Could Reduce the Risks of Some Cancers:
It is known that oxidative damage contributes to the development of cancer and that antioxidants can have a protective effect. And this tea is an excellent source of powerful antioxidants, so it makes sense that it can reduce the risk of cancer, which effectively seems to be done in relation to some manifestations of this disease:
- 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.
- Prostate cancer: One study found that men who drank green tea had a 48% lower risk of prostate cancer.
- Colorectal Cancer: A study of 69,710 women in China found that green tea drinkers reduced the risk of developing colorectal cancer by 57%.
Multiple observational studies also showed that people who drank this tea had a significantly lower tendency to suffer several types of cancer. In this sense, it is important to keep in mind that it is not a good idea to put milk on tea, because it could reduce its antioxidant value.
In short: It has powerful antioxidants that could protect against cancer. Multiple studies show that people who consume it have a lower risk of suffering from several types of the disease.
5. It Could Protect the Brain from Aging by Lowering the Risk of Alzheimer’s and Parkinson’s:
Green tea can not only optimize brain functions in the short term, but also protect it in old age. Multiple studies show that catechins in green tea can have protective effects on neurons in laboratory tests and on animals, potentially reducing the risk of Alzheimer’s and Parkinson’s
In summary: The bioactive components of the brain could protect neurons and reduce the possibility of suffering from neurodegenerative diseases.
6. Kill Bacteria, Improving Dental Health and Reducing Infection Risks
The catechins in green tea have other additional biological effects. Some studies show that they can kill bacteria and inhibit viruses such as influenza, potentially lowering the risk of infections. The streptococcus mutans, the main harmful bacteria in the oral cavity, inhibits growth hand catechins, so consumption of the tea is associated with better health and reduced dental caries incidence. Another great benefit of tea related to this last point is that multiple studies show that it can also fight bad breath
In summary: The catechins in tea inhibit the growth of bacteria and some viruses. This can fight infections, improve dental health, lower the risk of tooth decay and reduce bad breath.
7. Reduces the Risk of Type 2 Diabetes:
Several research shows that green tea can improve insulin sensitivity and reduce blood sugar levels. A study in Japan showed that people who drank the most green tea had a 42% lower risk of developing type 2 diabetes. And a review of seven studies with a total of 286,701 individuals showed that green tea drinkers reduced their risk of diabetes by 28%.
In summary: Some controlled studies show that green tea can cause slight reductions in blood sugar. In addition, it would contribute to the decrease in the risk of long-term type 2 diabetes.
8. Lower the Chances of Developing Heart Problems:
The consumption of this tea, according to some studies, may improve some risk factors for heart disease. This includes total cholesterol, LDL and triglycerides. In addition, it dramatically increases the antioxidant capacity of the blood, which protects LDL cholesterol from oxidation, one of the key steps in the process of heart problems. And considering the beneficial effects on these risk factors, it is not surprising that people who drink green tea may have up to 31% less chance of developing cardiovascular disease.
In summary: This tea lowers both total cholesterol and LDL, in addition to protecting LDL particles from oxidation. Observational studies show that green tea drinkers have a lower risk of developing cardiovascular problems.
9. Can Help You Lose Weight and Lower Your Risk of Obesity:
Whereas green tea can accelerate metabolism in the short term, a natural effect derived from that process is weight loss. Several investigations show that green tea can lead to a reduction in body fat, especially in the abdominal area. One of these studies was practiced in a controlled manner on 240 people for 12 weeks. The group that drank this tea showed a significant decrease in body fat percentage, weight, waist circumference and abdominal fat. However, other studies do not show statistically significant weight loss through the consumption of green tea, so this effect should be taken with caution.
Summarizing: According to some studies,it leads to an increase in weight loss and in the burning of abdominal fat.
10. Could Contribute to a Longer Life:
In a study of 40,530 Japanese adults, those who drank five or more cups a day of green tea had a lower mortality in the following 11 years:
- Death from any cause: 23% lower in women, 12% in men.
- Death due to heart problems: 31% lower in women, 22% in men.
- Death from strokes: 42% lower in women, 35% in men.
Another study that included 14,001 Japanese between 65 and 84 years found that those who consumed the highest amounts of green tea had a reduced mortality by 76% during the following six years
To Take into Account:
If you are looking for greater well-being, less fat and a reduced risk of several chronic diseases, it may be a great idea to make green tea an essential part of the diet.
