Is it true that green tea is more useful than black?

There is an opinion supported by marketers that green tea is more useful than black. We decided to check if this has a scientific justification.

The question of which tea is still more useful-black or green, is very popular on the Internet. It can be found in Blogs About tea, on sites specialized shops, culinary resources, in female magazines. Portals specializing in sports And healthy image Life, claim that green tea is most useful.

Tea in Russia is often called a variety of drinks - from classic black to chamomile and frame. However, in fact tea -These are the leaves of the Camellia Sinensis plant, everything else is just herbal decoctions, which are also called because of a similar cooking method. We will not talk about them in our analysis, since this is a completely separate voluminous topic.

There are a lot varieties Tea: black, green, white, oolun, puer, etc. Despite their obvious differences, all of them were really originally the same plant. Their appearance and taste is affected by the production process: the region of growth, the time of gathering, oxidation (or its absence), the drying method, etc. The most significant factor that affects the content of beneficial substances in tea is a degree oxidation (exposure to oxygen tea). Black tea is most oxidized, green and white are not oxidized, the oolong is partially oxidized. Quite often, even in scientific texts, the process of oxidation confused With fermentation, but these are completely different chemical reactions. Only a few types of teas are fermented, for example, Puer.

How green Tea, so black They help to prevent heart disease, slow down the formation of atherosclerotic plaques - this is confirmed by both theoretical studies and animal experiments. Both These species Tea contributes to a decrease in blood pressure. It was established that black tea Reduces the probability of developing coronary heart disease and reduces Cholesterol (in the study on rats, Chinese Puer tea was used). Japanese scientists found outthat the use of green tea reduces Mortality from all causes, and especially from cardiovascular diseases.

Green tea helps to withdraw toxins from the body - this was confirmed experiment, during which scientists for two months were given rats underwent with lead poisoning, the supplement of green tea. At the end of the study, they had a significantly lower level of lead in the blood than that of their relatives, who were not given green tea.

Black and green teas Contain Caffeine, which invigorates, raises the mood due to the release of serotonin and dopamine. At the same time, unlike coffee (another popular drink that helps to cheer up), tea contains L-theanine, which balances the effect of caffeine, having a relaxing effect on the body. Acting together, these two substances are more effective than separately caffeine, Help People concentrate attention and generally increase cognitive functions. It is worth noting that in green tea L-theanine is several more, but in Puer, on the contrary, there is almost no.

In green tea, at the same time, unique substances are contained - Catechins EGCGwhich, how They think scientists, Help Fight and prevent some types of cancer. Thus, researchers note the reverse dependence between the risk of cancer and the use of green tea by the inhabitants of the Asian region, where this drink has been common for many centuries. Mouse research too Confirmed The effectiveness of green tea in the fight against breast cancer in animals that received the same catechins, the development of the tumor slowed down. However, it is worth noting that most research, confirming the anti -cancer efficiency of green tea, was carried out on animals, which received doses of catechins significantly exceeding those that people usually consume. 

It is also a substance Helps In the treatment of Alzheimer's disease, supports liver health, Protects the body from the effects of bacteria and viruses, Prevents The development of osteoporosis. Catechins EGCG Contained In large quantities and in white tea, in its useful properties it is similar to green tea. In particular, there is researchconfirming that white tea Provides The effect on some types of cancer cells is due to the content of the same catechins.

Black tea, in turn, contains another unique substance - Theatlavinsthat help reduce blood cholesterol and blood sugar. In addition, they reduce the risk of developing cardiovascular diseases, for example atherosclerosis. Scientists suggestthat theaters can be effective in the fight against obesity. In fact, theatlaws in black tea Provide The body is approximately the same antioxidant effect as catechins in green. Although some researchers They thinkthat in green tea antioxidants still more.

Black Puer tea in experiments On animals demonstrated Efficiency in the fight against cancer cells. However, as in the case of green tea, animals (or directly cancer cells in a test tube) Received There are much large doses of tea (in terms of body weight), which is usually consumed by a person.

White tea, like green, protects the body from the effects of free radicals - this was confirmed as research on animals, and experiments With human cells. In addition, he Promotes weight loss and capable accelerate metabolism by 5% (as well as green).

Those who want to get everything at once can pay attention to Ulun. The leaves for him are only half oxidized, so it does not completely lose the beneficial properties that are in non -oxidized green tea, but at the same time partly acquires those inherent in black tea due to oxidation.

Thus, tea as a whole has many useful properties characteristic of all types of this drink. However, in oxidized (black), semi -oxidized (oolons) and non -oxidized (green and white) teas, the active substances are slightly different. Although, for the most part, the absence, for example, of the EGCG super-laid catechins due to oxidation in black tea is compensated by the presence of almost the same useful theatlavins. It is incorrect to say that one type of tea is more useful than another, it is worth just studying the properties of everyone and choosing one that is more important for the health of a particular person.
