What is tea and where does it come from?
Tea is a drink obtained by infusing the leaves of the Camellia sinensis plant (or Camellia theifera or Thea Sinensis) of the Teacee family. It has been cultivated since ancient times in India, China, and Japan; more recently in Indonesia, the Caucasus, East Africa, and South America.
When it grows in the wild it develops very similar to a tree (it can reach two meters in height), while when it is cultivated it takes on an appearance more like a low and branched bush.
The leaves are evergreen and have different shapes. Currently, there are different types of tea (including white tea, black tea, green tea, and oolong tea), which differ from each other in the manufacturing process, which is the most relevant factor for the differentiation of the finished product.
What is green tea?
Green tea, well known for its beneficial effects on the human body and above all for its antioxidant action, is obtained by subjecting the tea leaves to a thermal process called “stabilization” – which can be performed with dry heat (roasting) or moist heat (vaporization) – which inhibits the enzymes responsible for oxidation and therefore allows the leaves to maintain their characteristic green color (oxidation is a chemical reaction that occurs spontaneously in tea leaves, darkening their color).
Green tea is also defined as “unfermented” because it does not undergo fermentation (fermentation is the process of biochemical transformation by microorganisms that the tea undergoes when placed in suitable conditions of heat and humidity).
Green tea and metabolism
The processes that allow the body to convert food and drink into usable energy are collectively known as metabolism. Green tea may be beneficial for weight loss by helping the body’s metabolism to be more efficient, potentially due to its caffeine and catechin contents.
The metabolism is the set of biochemical processes that allow the body to convert food and drink into usable energy. Green tea may be beneficial for weight loss by helping the body’s metabolism to be more efficient, potentially due to its caffeine and catechin contents. Caffeine is a stimulant that increases activity in the brain and heart, helping to increase energy levels.
Catechins are compounds that have antioxidant properties and may help to reduce inflammation in the body. These properties may help to improve overall health and reduce the risk of obesity or other chronic diseases.
The possible benefits and contraindications
The human health benefits that can derive from the consumption of green tea are very many. This drink has already been and still is the subject of several studies, the aim of which is to learn more and more about its possible curative role.
Most of the benefits of green tea seem to depend on the presence of large quantities of catechins, able to strengthen the antioxidant defenses and therefore reduce the damage to cells, with positive effects on all tissues.
Polyphenols
Green tea contains very high amounts of polyphenols, substances with a beneficial and antioxidant role for the human body; in particular, the most characteristic polyphenol and main responsible for the properties of green tea is Epigallocatechin gallate (also known by the acronym EGCG, present in quantities about 10 times higher than black tea and 2.5 times higher than oolong tea).
Anti-tumor
In particular, green tea would have anti-tumor properties (it protects good cells from mutations and inhibits the growth of cancerous ones) and would bring benefits to the cardiovascular system (it inhibits the formation of clots, reduces the presence of fats and cholesterol in the blood and slows down the development of atherosclerosis and coronary heart disease) and respiratory (it is particularly useful against the negative effects of smoking).
Accelerates the metabolism
Green tea also accelerates the metabolism of fats and sugars, facilitating the decrease in body weight, and facilitating diuresis, being useful in case of water retention, cellulite, and urinary tract infections.
Thanks to the combined action of polyphenolic derivatives (flavonoids, chlorogenic acid, caffeine, tannins) contained in it, this type of tea would have neuroprotective effects and could play a role of some importance in the prevention and treatment of neurodegenerative diseases.
Re-mineralizing action
Green tea would also seem to be able to counteract hypertension and cause osteoporosis. Its powerful re-mineralizing action increases bone density in postmenopausal women. Several studies attribute anti-stress and anti-inflammatory effects to green tea.
Although the human health benefits that can derive from the consumption of green tea are very many, it is good to keep in mind that green tea contains caffeine and, therefore, when consumed in large quantities can cause anxiety, nervousness, and insomnia. Green tea can also affect the functioning of the thyroid gland.
Some studies have also shown that at certain concentrations green tea polyphenols can induce oxidative stress and liver toxicity (particular caution must therefore be taken when consuming concentrated tea extracts).

Is green tea extract good for losing weight
Many studies have shown that tea leaf extract can promote weight loss, glucose regulation, disease prevention, and exercise recovery. It also can help keep your skin and liver healthy, reduce blood fat levels, regulate pressure, and improve brain health.
Green tea extract is its concentrated form, with only 1 capsule containing the identical amount of active ingredients as a mean cup of tea.
Like tea, tea extract may be a great source of antioxidants. These are credited with a spread of health benefits — from promoting heart, liver, and brain health to improving your skin and even reducing the danger of cancer.
What’s more, many studies have checked out the flexibility of tea leaf extract to help weight loss. Many weight loss products list it as a key ingredient.
Despite these benefits, it’s important to understand that tea leaf extract may be toxic when taken in excess, so always talk with a health care provider if you’re inquisitive about taking these supplements.
Overall, there is evidence that green tea extract may play an important role in helping people achieve healthy body weight. However, more research is needed in this area before a definite conclusion can be made.
