If you drink a daily cup of this drink, you can significantly improve the health status and prevent even the toughest conditions.
Green tea is considered one of the most popular beverages – consumed daily by about a billion people on the planet. Most are grown in China and Japan, but scientific research has shown that this is the healthiest drink, because it is rich in antioxidants and nutrients that strong effect on the body. It is known that green tea improves brain function, metabolism, encourages weight loss, and even prevents malignant diseases. However, all this applies only if you drink moderately, one to two cups a day.
Cup of quality green tea is rich in polyphenols, such as flavonoids and catechins, known for its strong antioxidant effect. These substances may reduce the formation of free radicals in the body, and thus protect the cells from damage and molecule. Also, slow down aging and prevent various diseases. One of the more powerful compounds in green tea is an antioxidant epigallocatechin gallate (most of it is in the young leaves and buds), which, as has been noted, leaflets a number of diseases and prevents malignant diseases. This drink contains a smaller amount of mineral important for health. However, in lower quality green teas (especially in older leaves) can be found excessive amounts of fluoride, a mineral that interferes with the operation of the thyroid. So, although somewhat expensive, always buy quality species, which mostly contain the young leaves and buds.
Improves brain function
A cup of green tea can wake us for a moment, but also make you smarter. One of the key ingredients of this drink is caffeine, a stimulant known as. True, it’s not as rich as the coffee, but it contains enough to operate similarly. Caffeine blocks the inhibitory neurotransmitter in the brain adenosine. Thus, increases communication between the neurons and the concentration of neurotransmitters, such as dopamine and norepinephrine. Previous studies have shown that caffeine improves a variety of brain functions, including mood, as well as to increase alertness, reaction time and memory. Green tea contains the amino acid and theanine, which bridged the barrier between blood and brain. This amino acid increases the activity of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid), having an antianxiety effect. Also raises dopamine levels, improves learning ability and concentration, and lowers blood pressure. Studies have shown that caffeine and theanine may have a synergetic effect. In doing so, some research suggests that green tea may protect the brain from aging and slow the development of Alzheimer’s and Parkinson’s disease.
Reduces the risk of cancer
It is scientifically proven that antioxidants prevent malignant diseases, green tea is rich in this valuable compounds, which destroy free radicals and prevent oxidative damage.
* Breast cancer: a meta-analysis of observational studies showed that the fairer sex who drank more green tea had a 22% lower chance of developing breast cancer, the most common type of cancer among women.
* Prostate cancer: One study showed that people who drink green tea daily had a 48% lower risk of developing prostate cancer, the most common type of cancer among men.
* Colorectal cancer: study, which was attended by 69 710 Chinese girls has shown that those who drink green tea are 57% lower risk of developing colon cancer. However, it should be borne in mind that adding milk significantly lowers the levels of antioxidants in green tea.
If consumed moderately (1-2 cups a day), green tea has no adverse health effects. However, pregnant women and nursing mothers should avoid it because they confer reduced intake of caffeine. Also, some experts warn that green tea cancels the effect of anticoagulants. People suffering from hypertension, insomnia, asthma or heart problems before they start drinking green tea, you should consult with your doctor, who will assess the quantities of the beverage safe.
