YOU THE 'GREEN: A MYTH
tea comes from the leaves of Camellia sinensis, and when we hear of Jasmine tea, Ceylon, Darjeeling , we must not think that this is different plants: the only place of production el'aromatizzazione. Even green tea and black tea come from different plants.
What I normally drink in the West is black tea: the leaves, after being harvested, are heated in air for one day, rolled and fermented in damp areas (a process that wastes most of the active ingredients of the plant) .
If the same leaves, freshly picked, they are "washed" with steam and dried immediately to prevent fermentation, you get the green tea. Thanks to this working within them remain higher amounts of catechins and other polyphenols (The components active and healthy) and you lose a bit 'of protein (or caffeine). Green tea, in short, is a concentrate of precious substances, although the taste a bit 'different from the "classic" does not make him popular as black tea.
To maintain non-active, pero ', you must know how to properly prepare: pour a couple of grams on the bottom of the cup and fill it with cold water and one part hot water. Boiling water, in fact, reduces the green tea leaves. After leaving it to infuse for two to four minutes, strain, add lemon and sugar if necessary, but remember not to add milk, just because the milk casein may Polyphenols neutralize the beneficial components of green tea.
In Japan, tea (green rigorously: the black, considered to be of low quality, is usually reserved for the West) is the national drink. In this country there is a situation that has surprised researchers around the world, a "Japanese paradox": Why The Japanese, among the heavy smokers in the world, get sick less than elsewhere of lung cancer? Why drinking green tea. So 'the interest of oncologists for this ancient beverage, has soared.
Of course, we must not be carried away. How often have you heard of substances cancer after a few months had already finished the back burner? But green tea should not be so '. The first major studies dating back more than ten years ago. And now they are dozens of studies published in journals proof of doubt: JAMA, the Journal of the American Medical Association, in Lancet, British Medical Journal at the Japan Journal of Clinical Oncology. Researches have shown that in many cases the substances contained in green tea slow or stop the transformation of normal cells in tumors, their cresciota and dissemination, and development of blood vessels that nourish the tumor. The matter is particularly EGCG (the full name is epigallocatechin-3-gallate), a polyphenol present in tea green (25%) more than in the black (which has only 4%).
What prevents cancer? Practically all: breast, lung, esophagus. Thwarts even the melanoma and a male cancer such as prostate.
And the heart? Green tea is good also our most important muscle. It contains numerous flavonoids, antioxidants that protect us from heart. Not only that. Cholesterol and triglycerides in the blood, which when in excess is deposited on artery walls and pave the way for heart disease, in heavy tea drinkers are not a problem. In general, with two cups a day reduces the risk of atherosclerosis by 50%. Antioxidants present
green tea (Flavonoids which we have just spoken, and especially the catechins) also fighting the free radicals responsible for aging skin and body in particular. But the beauty is that they are much more active than any other antioxidants in food: according to research by some American universities, the catechins in green tea are 20 times more effective than vitamin E and 100 times more active in vitamin C.
But not enough. Green tea has the ability to improve the intestinal flora, and finally gives a hand to lose weight, because it increases the speed at which your body burns its fat. 'S University of Geneva discovered that his statements are rising significantly (4%) the daily consumption of calories. This effect is not, as you might think, from the protein or caffeine in tea (which is also included in many weight-loss drugs because it speeds up your metabolism), but is given again by the precious catechins, which increase thermogenesis: the Our bodies produce more heat and, therefore, 'burns more fat. Without causing any adverse effects affecting the heart and nervous system.
