benefits of this plant and its reputation seems deserved: good for the heart,
brain. tea would fight against many diseases Black or green, overview of the
benefits of a small cup.
It adorns the tea many health benefits. And the latest
studies seem to confirm these claims.
A drug food?
No health without tea & nbsp ;! Why do scientists have
they addressed the benefits of tea? Simply because it is a cocktail of very
interesting compounds. This plant is rich in well-known substances for their
protective properties polyphenols. These have an antioxidant action they can
fight against excess formation of free radicals in the body, promoting
substances premature aging of cells and the onset of disease. And the tea
contains powerful antioxidants: catechins (especially green tea), theaflavins
(especially black tea), flavonols ... They would be even more effective than
vitamin C and E!
An anti-cancer weapon!
Scientists around the world have of course asked if tea
antioxidant power could protect against one of the most important diseases:
cancer. And the results weigh in favor of this drink. And several studies have
highlighted the anti-tumor effects of tea polyphenols, both in vitro and in
animals 1 . In humans, several studies have shown a protective effect against
cancer (most often related to black tea apparently). Thus, this plant would
reduce the risk of breast cancer 2 women. But men are not left out: tea may
protect against prostate cancer 3 . Some work 4 also point out that tea
consumption provides little defense against UV rays, helping the skin to fight
against sun damage. But we must recognize that in terms of cancer prevention,
tea remains controversial: several studies 5,6 have not achieved positive
results, some even showing an increased risk associated with the consumption!
Good for the heart
In the prevention of cardiovascular disease, tea has been
proven. Thus, it limits the formation of atherosclerotic plaques responsible
for clogging of the arteries. The mechanism would be linked to this plant
antioxidants that prevent the oxidation of bad cholesterol and decreasing the
formation of dangerous plaques. But the tea polyphenols also have an
antithrombotic effect (against the formation of clots that can block an
artery). In general, drinking three cups of tea per day would reduce by 11%
cardiac events. But be careful not to exceed the dose: excess tea may decrease
the absorption of iron in the intestine: anemia station, especially in pregnant
women 7 !
Reztez Zen!
But the tea is not only good for the body: it is also for
the head! Certainly it contains caffeine, better known under the name of
caffeine, but two times less than a black child. Of course, this depends on the
duration of the infusion. According to the scientific information center on
tea, an infusion of 3 minutes extract of the plant 50% of the caffeine, against
80% for an infusion of 5 minutes. Moderate consumption of this substance
therefore increases alertness, especially when one is tired. Moreover, the fact
consume a hot drink like tea help to fight against stress. This allows in
particular to fight against the constriction of blood vessels in the
extremities, reducing such problems sweaty hands for anxiety!
Against the weight: no miracles ...
However, needless to believe that tea makes you lose weight.
Of course if you do not add sugar, one cup will bring only two small calories
and can help eliminate toxins through a high protein diet for which to drink a
lot. Admittedly, some studies come restart slimming properties of this drink.
Thus, a Japanese study has recently shown a greater loss of weight when diet
was associated with tea consumption. But do not get carried away: it was work
in obese diabetic mice rendered ...
So if you want to eliminate a few pounds, nothing prevents
you from drinking tea, but rather bet on a suitable diet and some exercise!
