A study by the University of Hong Kong found that drinking three cups of green tea a day, especially Longjing tea, can effectively inhibit Helicobacter pylori and reduce the chance of gastric ulcer. Because catechins in green tea can inhibit or even kill Helicobacter pylori, which causes gastric ulcer and duodenal ulcer, people who have the habit of drinking tea have a low chance of finding Helicobacter pylori in their stomachs.
The rise of scented tea is a matter of one or two years. In addition to various packages of slimming scented tea, many people are also interested in real scented tea. The attraction of scented tea lies in its sweetness. Just smelling the flowers will make you feel fresh and happy. In addition, different kinds of scented tea have unique efficacy and no side effects. No wonder it has become the favorite of slimming and health-conscious people. In recent years, slimming has become popular, and at the same time, scented tea has also become popular. Scented tea is a drink with good color and fragrance. Can lose weight, which is of great help to the body. Because scented tea, unlike black tea or China tea, contains addictive substances and can be drunk every day.
Eliminate fat
Scented tea is rich in vitamins C and B2, as well as folic acid, iron, calcium and vitamins. Although scented tea is also a kind of tea, it does not contain caffeine like ordinary black tea or China tea, and it is definitely not addictive. Scented tea has the functions of soothing body functions, regulating psychology and relaxing nerves, and can also treat emotional instability and other problems.
It must be mentioned that scented tea also has the effect of slimming, such as rose tea and lemon grass, all of which have the effect of reducing fat and helping digestion. Moderate drinking helps to reduce the fat accumulated in steamed bread. Generally, there are many kinds of scented tea on the market, each with different curative effects, and you can choose the right one according to your own needs.
Neutralize the cold of scented tea
From the perspective of Chinese medicine, scented tea is a cold thing. If women drink too much, they may have symptoms such as allergies or cough. The reason is that women belong to yin, and cool scented tea will have a certain impact on women's physical function. Unless you add ingredients to neutralize the cold of scented tea, it is even more inappropriate to drink too much. For example, chrysanthemum needs medlar, rose tea with black tea, osmanthus with licorice, which can effectively dispel the cold of scented tea itself.
Use transparent tea sets
Scented tea is not only a taste enjoyment, but also a visual and olfactory enjoyment. Therefore, when brewing scented tea, you will generally choose a transparent tea set and enjoy the beautiful color of scented tea while brewing. In fact, transparent tea sets also make it easy for you to distinguish the concentration of scented tea by the color of tea leaves when making tea. In addition, scented tea will be brewed in a thermos to keep the fragrance overflowing. It is more than enough to light a small candle for the mushroom seat.
Green tea and oolong tea are produced by the same kind of tea tree. The biggest difference is whether it has been fermented or not. Because the catechins in tea will combine with each other with the increase of fermentation temperature, the color of tea will become darker, but the astringency of tea will also decrease. The component formed by catechin combination is the polyphenol of oolong tea. Antioxidant polyphenols and catechins can affect the activation of various enzymes in our body. About half of catechins in tea will be converted into polyphenols in oolong tea. Therefore, under the dual effects of catechins and oolong tea polyphenols, oolong tea shows various functions that green tea does not have.
The effects of oolong tea are as follows:
1, prevention of tooth decay:
Drinking a cup of tea after a meal can not only promote fluid production and relieve cough, but also refresh your breath. Oolong tea also has the function of preventing tooth decay. The cause of tooth decay is that bacteria invade the tooth tissue and produce enzymes in the tissue, which leads to tooth decay. This enzyme reacts with sugar contained in food to produce substances that corrode teeth. This substance and bacteria that can decay teeth adhere to the teeth to form tartar, and after accumulation, tooth decay will occur.
Polyphenols contained in oolong tea can inhibit the production of tartar enzymes, so drinking a cup of oolong tea after meals can prevent the occurrence of tartar and tooth decay. Scientists have proved through long-term experiments that letting white rats eat feed containing polyphenols will reduce the probability of tooth decay. If you don't have time to brush your teeth after meals, drinking a cup of oolong tea to prevent tooth decay is also a good choice.
2. Eliminate reactive oxygen species harmful to beauty and health;
Reactive oxygen species are substances produced in the body due to ultraviolet rays, smoking, food additives, stress and other factors. It turns body fat into peroxide fat, which leads to lifestyle diseases and hinders health. At the same time, reactive oxygen species can also cause skin aging, wrinkles and a series of problems that hinder beauty.
There is an enzyme SOD in human body, which can successfully decompose reactive oxygen species. This enzyme is indispensable for maintaining health and beauty beauty. Polyphenols in oolong tea have the same function as SOD, which can promote SOD to eliminate active oxygen.
We all know that the growth of skin needs vitamin C. If active oxygen is produced, vitamin C will be consumed. The antioxidant effect of oolong tea polyphenols can eliminate active oxygen, and then inhibit the consumption of vitamin C, so it can keep the skin delicate and fair. In addition, oolong tea itself contains vitamin C, which can kill two birds with one stone for whitening skin. Vitamin C will be excreted with urine in about 2-3 hours. Therefore, drinking oolong tea at any time can whiten the skin and ensure the supplement of vitamin C.
3. Drinking 1 L oolong tea every day can improve skin allergy;
A survey shows that allergic dermatitis is very common in patients with skin diseases, but the cause of this dermatitis is still unclear. But oolong tea can inhibit the development of the disease. By making experiments on skin inflammation symptoms of mice, it is proved that oolong tea has inhibitory effect on dermatitis of mice.
A foreign expert once found that 12 1 adult allergic dermatitis patients, treated with existing steroids and antiallergic drugs, still could not improve their condition. Later, after drinking 400ml concentrated oolong tea every day, one month later, 78 of them (64%) had obvious improvement in symptoms.
4, drinking oolong tea can lose weight:
We often hear that drinking oolong tea can "dissolve fat". Especially after eating too much greasy food, drinking oolong tea can decompose oil, so is this statement correct? The unconsumed energy in human fat cells is stored as neutral fat so as to be used as energy in exercise. At this time, neutral fat is decomposed into necessary energy for use under the action of enzymes such as protein-like lipase. Drinking oolong tea can improve the function of protein-like lipase That is to say, oolong tea itself can't dissolve fat, but it can improve the enzymes that decompose fat, so after drinking oolong tea, the amount of fat metabolism also increases relatively, thus playing a role in slimming.
Some experts have done experiments on 102 obese adults, drinking 600cc oolong tea twice a day, 300cc each time in the morning and afternoon, for 6 weeks. During this period, no other weight loss or food therapy was used. Results The weight loss was not obvious, but the waist circumference, abdominal subcutaneous fat, blood neutral fat and blood total cholesterol all showed a significant downward trend, which was related to polyphenols contained in oolong tea.
5. Anti-tumor and anti-aging effects:
Oolong tea can promote blood lipid decomposition and reduce cholesterol content. A foreign 1994 experimental report on the efficacy of oolong tea pointed out that oolong tea has a quite good curative effect on patients with hyperlipidemia and hypertension. In particular, among the 68 hypertensive patients in Gao Xue who participated in the trial, 75% of them showed a downward trend in blood pressure after one-stage test.
In addition, oolong tea also has the functions of anti-tumor, improving the activation of lymphocytes and NK cells, enhancing immune function and preventing aging. Experts have found that oolong tea polyphenols can also absorb foreign bodies in the body and discharge them together.
For so many amazing effects of oolong tea, experts point out that the amount of oolong tea that can produce effects every day is about 1 liter. If the amount cannot reach 1 liter, it is necessary to brew strong tea to drink, so as to obtain enough polyphenols. In addition, it should be noted that it is unscientific to drink a lot of oolong tea once a day. The correct way is to drink oolong tea several times a day, so that the polyphenols in oolong tea can be fully absorbed by the human body. Also, you should get into the habit of drinking a cup of oolong tea after dinner.
