Green tea is. All l endowed with prodigious characteristics. In particular for its propertiesiving beings, from the thermodynamic point of view, are defined as open systems. That is, to live they need to continuously interact with the external environment. In particular, to produce energy and absorb the matter necessary to reach a condition of thermodynamic equilibrium called homeostasis. Similarly, the set of chemical processes that aim to supply energy to the body are called metabolism. In other words, energy molecules such as sugars and fats or sometimes even proteins are broken down to obtain energy.
Metabolic processes aimed at energy production often generate highly reactive waste compounds. In particular they are called free radicals. In other words, molecules with a “sapid” electron with a high tendency to react with the molecules with which it comes into contact. Then, due to this characteristic, they have a high oxidizing power, in other words they are capable of altering the structure of many organic molecules. That is, free radicals, if present in abundance and constantly in the body, can cause damage to body tissues and chromosomes by damaging the DNA. In other words, the production of free radicals is inevitable because it is a consequence of the metabolism. Then, the damage caused by free radicals is called oxidative stress. For example, it is damage that alters the structure of many molecules in the body. In addition, all these oxidative phenomena accelerate aging and increase the risk of cancer.
Free radicals are the result of metabolic processes. That is, the reaction of chemical compounds with oxygen. In particular they are unstable and very reactive molecules because they have “unpaired” electrons and therefore very unstable. That is, they stabilize by subtracting an electron from other molecules and thus altering them. In other words, they harm the body. That is, oxidative stress produces heart disease and degenerative diseases. First of all it is possible to prevent oxidative damage by avoiding smoking, life in polluted environments, an incorrect diet.
Secondly, the organism has evolved tools to defend itself against these harmful agents. That is, it uses antioxidants to stabilize free radicals and make them harmless to cells.
These antioxidant molecules can be introduced into the body through proper nutrition. In addition, they are contained in many foods, especially of plant origin. Especially vitamin C, vitamin E and flavonoids are the most useful antioxidants. Then they are readily available within many plant products. Antioxidants abound in many commonly used foods. In particular I am talking about vegetables, fruit, oil seeds, red wine, dark chocolate, in addition to green tea which is endowed with prodigious characteristics.
Green tea is a variant of tea that is not subjected to oxidative processes during processing. In particular, the finest green teas are covered in the sun in the two or three weeks prior to harvesting. That is, the sun’s rays are shielded by bamboo mats spread over the fields. In other words, this technique reduces the formation of chlorophyll by increasing that of flavonoids. In addition to amino acids, sugars and vitamin C.
First of all, this technique improves the flavor by making it more delicate. Secondly this type of tea is not fermented and this is why the leaves remain with the green color. Moreover, after drying the leaves are placed on bamboo mats and left for a few hours in the sun. Then treated for 30 seconds with steam at 100 ° C to inactivate some thermolabile enzymes. Similarly, 4 drying phases of about 30 minutes each follow. Finally, a cleaning and packaging process follows.
PROPERTIES OF GREEN TEA
Green tea is becoming increasingly popular. In particular, because the most recent studies have shown that it is endowed with prodigious characteristics. First of all, there is a lot of talk about the benefits this product brings to health. Secondly, the characteristics that make this tea useful as an ally of beauty are now known. In addition to the fight against aging. Then it was shown that the antioxidant power of this drink is due to its catechin content. In particular, these substances correspond to 20-40% of the dry weight. Moreover, among them the most abundant is epigallocatechin gallate or EGCG. Thanks to this substance, tea is particularly useful in the fight against tumors, high levels of LDL cholesterol and triglycerides.
TE ‘ALLY OF SLIMMING PROCESSES
Green tea contains substances called methylxanthines. In particular, caffeine, theobromine and theophylline belong to this category of chemical compounds. Especially these substances favor the mobilization of fats localized in the adipose tissue. Then also their use for energy purposes. In addition, green tea is a well-known exciting substance. That is, it has a stimulating action on the metabolism and therefore on the burning of fats and the reduction of blood sugar. Then green tea also has a good diuretic effect.
GREEN TEA AND INCREASE OF MENTAL SKILLS
Tea contains caffeine which, like coffee, has a stimulating action on the brain. But not in doses that cause health problems. For example, research has shown that caffeine or theine blocks an inhibitory neurotransmitter called adenosine. In other words, all this produces an increase in the level of activation of the electrical activity of the neurons. First of all this is due to the increased production of neurotransmitters such as dopamine and norepinephrine. Then another element contained in the tea that stimulates brain function is the amino acid L-theanine. In particular, it acts in synergy with theine.
ANTI-CANCER ACTION OF GREEN TEA
Earlier I talked about the antioxidative function of green tea. In addition, it has been shown that the onset of tumors can be favored by a state of chronic inflammation. Then the prolonged oxidative damage can have an inflammatory action. That is, an effective antioxidant reduces inflammatory states and therefore the risk of them generating tumors. In particular, research has shown that green tea is particularly useful in the prevention of certain types of cancers. In particular I am referring to breast cancer, prostate cancer, colorectal cancer, skin and uterine cancers.
OTHER PREVENTIVE ACTIONS ON MANY DISEASES
Then green tea slows brain aging. In particular, it has been shown that it is endowed with prodigious characteristics. That is, the catechins present in tea are effective in protecting the central nervous system from neurodegenerative diseases. That is, like Alzheimer’s disease or Parkinson’s disease. Likewise, this drink reduces the risk of dementia linked to these pathologies.
Then green tea makes the action of insulin more effective in managing blood sugar. In other words, tea reduces the risk of having type 2 diabetes problems.
In the same way, it prevents cardiovascular pathologies and the increased risk of stroke by acting in a positive way on important risk factors such as LDL cholesterol.
Then the antioxidant effects of tea and its preventive action against many diseases have a positive action in extending life expectancy. Especially towards the regular consumers of this drink.
PREPARATION OF GREEN TEA
Drinking tea, and green tea in particular, does not simply mean drinking just any beverage. In particular, it is endowed with prodigious characteristics that require careful preparation. That is, it is a procedure that begins with the preparation of the drink and ends with drinking and slowly enjoying this exceptional product from an organoleptic point of view. Each food preparation requires a precise procedure. Tea especially requires a rich tradition. In other words, the tea ritual begins when the saucepan with water is placed on the fire and ends when the drink is drunk. First of all you need to get the necessary ingredients and tools. That is: 1) A SPOON OF GREEN TEA IN LEAVES FOR EACH CUP (250 ml of water). 2) BOILING WATER. 3) 4 MINT LEAVES OR A PIECE OF FRESH GINGER. 5) HONEY
POUR BOILING WATER INTO A CERAMIC TEAPOT OR IN A STAINLESS STEEL POT (A WATER TEMPERATURE OF ABOUT 80 ° C IS RECOMMENDED)
PUT THE TEA INFUSION FOR 3 MINUTES IF YOU PREFER MINT OR GINGER TOGETHER
Filter the tea by pouring it into the cup
SOME ADVICE TO IMPROVE THE TASTE OF THE DRINK (add a teaspoon of honey and a little lemon juice, it is preferable to prepare the tea using mineral water, avoid infusing the tea leaves in too hot water because this would alter too much flavor and organoleptic properties)
