Uncle Liu has been obsessed with drinking tea for health recently. He always takes a pot of strong tea with him every time he goes out. Old friends think it is not good to drink too much tea, but he retorts fiercely every time.

"You don’t understand, how many articles and reports on the Internet say that drinking tea is good for your health, can open channels, can treat Alzheimer’s disease, and can improve many diseases."

However, he thought he was healthy, but in the latest physical examination, many values were not up to standard, and he even suffered from kidney disease and gastritis.

On the contrary, other friends’ reports are very healthy, which makes him puzzled. Why do you get so many diseases when you insist on drinking tea for health?

01

Fudan university research:

Can tea stimulate human meridians?

I believe everyone has heard of the rumor that tea can pass through meridians, but it has always been doubtful whether it is true or false. After all, even the meridians that Chinese medicine has always emphasized are an audible thing to many people, but they have never seen it before. Because it cannot be objectively presented, many people think it is pseudoscience.

However, a research team of Fudan University successfully displayed the meridians through imaging technology by drinking tea. What happened?

Searching the papers about the research team in the journal Quantitative Biology shows that the researchers observed the fever images of the subjects by using twelve kinds of tea, and found highly consistent meridian tropism results. Finally, the meridian model was successfully simulated by using infrared radiation images of human body through the stimulation of tea on specific meridians. Moreover, different kinds of tea will be classified into different meridians.

Systematic image source data map conforming to the traditional description of human meridians

However, there are still many controversies about the results in the industry, and the research has only carried out preliminary experiments, which can not completely confirm the effectiveness.

Some’ discussions’ by netizens have also made these doubts rampant. For example, whether the heat change path used in the experiment excludes other biochemical factors, the sample size is too small, and the variables such as tea temperature are not explained. Therefore, it is still doubtful whether drinking tea can open and stimulate people’s meridians.

02

Drinking some tea every day has so many benefits!

Although many rumors about drinking tea are hard to distinguish between true and false, what is certain is that the internationally recognized benefits of drinking tea are indeed beneficial to the health.

1. Reduce the risk of cardiovascular disease.

The European Journal of Preventive Cardiology has published a research paper on the relationship between drinking tea and reducing the risk of cardiovascular and cerebrovascular events and all-cause death. According to the research, people who have tea drinking habits have higher health indicators, pointing out that drinking tea has a certain effect on reducing the rate of cardiovascular diseases.

2. Reduce the risk of diabetes.

The American Journal of Clinical Nutrition also published a study on the relationship between drinking tea and chronic diseases in China. According to the experimental data, the risk of type 2 diabetes, all-cause death and microvascular complications of people who drink green tea every day are reduced by 8%, 10% and 12% respectively. It shows that drinking tea is of great significance to prevent type 2 diabetes and the risk of all-cause death.

3, help to resist oxidation

This is because tea polyphenols in tea itself have antioxidant effect, and the antioxidant effect is 18 times higher than that of vitamin E.

4, refreshing, diuretic fatigue

Tea also contains caffeine, so some people will feel excited and can’t sleep after drinking tea. Therefore, drinking tea also has the effect of refreshing the brain. In addition, these substances will stimulate the kidneys and have the effect of diuresis. Caffeine can also eliminate excessive lactic acid in urine, so it also has the effect of relieving fatigue.

Although tea is good, we should also abide by the principle of moderation, otherwise excessive drinking of tea will also lead to caffeine poisoning or other adverse reactions. In addition, it needs to be emphasized that tea does not belong to the category of drugs, and it has no effect of curing all diseases. Therefore, if you feel unwell, it is recommended to seek medical treatment in time.

03

Three misunderstandings about tea,

Don’t be fooled.

With the expansion of the demand for tea and the profit-seeking market, many "rumors" about tea have been heard all the time. How many misunderstandings do you believe?

1. Tea is full of pesticides.

There are rumors that non-organic teas are all grown up by spraying pesticides, and there are many pesticides left in the tea. However, in fact, the regulations on the use of food pesticides stipulated by the state are very strict. Generally, the tea that is listed in compliance has undergone strict sampling inspection and will not be "all pesticides".

2. You can’t drink tea when it expires.

This actually depends on the situation, because after the tea is dried, if it is properly preserved, even if it exceeds the shelf life, it can actually continue to drink, with little impact. If the tea leaves get wet, deteriorate, change color obviously, and smell, you should never continue drinking even if the shelf life has not expired.

3. Green tea is cold and black tea is warm

In fact, green tea and black tea are the same kind of fresh tea. As a result of different production processes, the general factory will make the fresh leaves fail by oxidation at high temperature, so as to prevent "tea polyphenols from discoloring", that is, "deactivating enzymes" in jargon, while black tea is the opposite, so that tea polyphenols can be fully oxidized and discolored, thus obtaining the flavor of black tea. As for which "warm" and "cold" is actually just a statement of packaging needs.

04

How to drink tea is more beneficial to health?

In fact, there is a lot of knowledge in drinking tea. If you want to give full play to the greatest role of tea, you should be particular when drinking it!

1, the brewing temperature is appropriate.

Different teas also have different brewing temperatures. For example, green tea is suitable for brewing with water around 80℃, while black tea and oolong tea need boiling water to fully separate out their own flavor.

2. Let the tea cool before drinking.

Many people like to make tea with hot water and immediately pour it out "while it is hot", but hot tea is very harmful to esophageal health, and even increases the risk of esophageal cancer. The International Agency for Research on Cancer also recommends not to drink hot drinks over 65℃, so it is better to let the tea warm before drinking.

3. Drink more light tea and less strong tea.

The concentration of caffeine in strong tea is higher. If taken too much, it will lead to insomnia, and it will also increase the burden on the kidneys, stimulate the stomach and deepen the symptoms of anemia. It is suggested that the amount of tea leaves should be controlled within 12 grams per day. Generally, 3 grams of tea leaves are soaked in 150ml of water, and 3 cups a day is enough.

If you want to drink tea well, in addition to mastering the above best tea drinking methods, you should also pay attention to the taboos when drinking tea, such as not drinking tea on an empty stomach and not drinking tea after drinking, so as to drink healthy.

Live on November 8th In an interview with titan sports, Capello, a famous Italian coach who once coached Jiangsu Suning, talked about his views on China football.

-You have coached star players like teixeira in Suning, and also coached many China players, including some international players. What’s your impression of China players?

I always had the feeling that when I saw those China players, they looked great. But when foreign aid arrived, they seemed to get worse in speed and technology. It stands to reason that with such a huge population base, supplemented by care and determination, China football should produce great stars. You are great at all sports, why not football?

A huge difference between China football and Italian football is that foreign aid can make everything different in the China League; Not in Italy.

Of course, for China football, foreign aid still plays a role: playing with better players will help you become better. Similarly, Serie A teams need to adapt to a faster pace when they play in the Champions League. Once upon a time, Italian football was at the top of the world. The root cause was that the best players played in Serie A at that time. They improved the rhythm of the whole league, so everyone played better.

-I don’t know if you remember that Min Kim Zai once played for the Super League, but it was after you left Jiangsu. Naples, where Min Kim is located, has not only performed well in the league, but also demonstrated its full dominance in the European War.

Italian football is growing. Don’t forget that we won the European Cup last year. Naples is amazing as well as surprising. This club knows how to find good players. Min Kim and Kvaratskheliya, two Serie A players, have the strength to be top stars in any league, because they have both strength and skills, are extremely focused in the game and are gifted! Don’t forget, they are still very young.

Femininity is a complex and multidimensional concept, which covers many different characteristics and qualities. The following are some common manifestations of femininity:

1. Tenderness and consideration: Women are generally considered to have the characteristics of gentleness, consideration and care for others. They are good at expressing their feelings, paying attention to the needs of others and giving them support and care.

2. Elegance and taste: Women are often described as elegant and tasteful. They pay attention to the details of appearance and have a strong interest in fashion, beauty and art.

3. Compassion and kindness: Women often have the qualities of compassion and kindness. They feel the pain and difficulties of others and are willing to provide help and support.

4. Delicate and sensitive: Women are usually considered to be more delicate and sensitive in emotion and perception. They can detect other people’s emotional changes and have a sharper insight into the surrounding environment and interpersonal relationships.

5. Perseverance and perseverance: Women can also show their tenacity and perseverance. They can make unremitting efforts to pursue their goals in the face of difficulties and challenges.

It should be noted that femininity is not fixed, and everyone has their own unique personality and characteristics. Moreover, femininity is not unique to women, and men can have similar qualities and characteristics. Gender should not be the only criterion to define personal characteristics, and everyone should be respected and understood, regardless of gender.

China Education News-China Education News Network (Reporter Zhou Hongsong) Recently, Langfang City, Hebei Province, combined with the actual situation, formulated and promulgated the Ten Measures to Promote the High-quality Development of Education in the City (hereinafter referred to as the "Ten Measures for Education"), and refined specific measures from five aspects: comprehensively strengthening the party’s leadership, filling the shortcomings of educational resources, building high-quality teachers, improving the quality of education and teaching, and creating a good educational ecology, so as to speed up the construction of a strong education city and run a satisfactory education for the people.

After Tomb-Sweeping Day, the weather is really warm. The temperature in Guangzhou has been close to 30 degrees recently. What does this portend?The season of learning to swim is coming again!The swimming pool is going down to jiaozi again!

Summer is the season of ice cream and swimming. Big friends and children who can’t swim yet and are ready to learn to swim must have many questions about learning to swim. Today, we will answer common questions, hoping to help you enter the swimming learning stage faster and better.

First of all, I want to remind you of one thing:Don’t take the expectation of "swimming well" and just pay the effort of "swimming".

It is not difficult to learn to swim. First, we should define the standard of "meeting":

If you just want to swim forward in the water without choking and enjoy swimming in the water,Then a short swimming crash course can satisfy you, after continuous10 ~ 15 classes of study,90% people can learn the first breaststroke and start swimming in the water.

The remaining 10% is basically because the degree of fear of water is relatively deep, which delays the learning progress. Adding more classes can also achieve the goal.

But if you have a high standard of "meeting",Require beautiful standard swimming strokes; A slow speed; A long distance of continuous swimming,It will take longer to learn. You can swim in the water, improve your movements through constant practice, and become familiar with the interaction with the water. You can naturally make continuous progress over time. This cycle depends on the frequency of swimming and the degree of serious study.

Generally speaking, it takes 3 ~ 6 months, and most people can swim one or two hundred meters skillfully with the enlightenment breaststroke.

Sure!

Mass swimming is not an intense sport. As long as there are no physical defects or diseases that can’t make you exercise, you can learn to swim.

What you need is to hold the confidence that I can learn to swim, and then study hard.

After all, there are many people who learn freestyle in our training camp in their 60s.

There are two separate direction:

1. learn to swim

2. Cultivate your interests.

If you just learn swimming, you can sign up for it after you are 7 years old.Most of the swimming training enrollment age limit will also be above 7 years old, because children under 7 years old are relatively weak in understanding and body control, and the short-term training effect is not good. Because of fun, there may be security risks.

If you want to cultivate your interests, it is recommended to start enlightenment at the age of 3.Parents can take their children to play in the water as soon as possible, get familiar with the sense of water and water, and let their children have a deeper affinity for water, which is conducive to subsequent study and training. At the age of 5, you can start learning swimming movements.

"Coach, I think foreign countries learn freestyle or backstroke first, and we all learn breaststroke first in China. So which is better to learn first?"

First of all,Swimming is divided into mass swimming and competitive swimming.Competitive swimming is the butterfly, the back, the frog and the self in the competition, while mass swimming contains many kinds of fitness swimming, such as side stroke, reverse breaststroke and our common enlightenment breaststroke, that is, flat frog.

There is only competitive swimming in the swimming training system abroad. Simply put:Everything is based on professional competition.

And it is more humanized in China.Pay attention to "let’s swim in the water first",Using the more simple and easy-to-learn enlightenment breaststroke as a beginner stroke, you can learn to swim in a shorter time and enjoy swimming.

If you have more time, energy and economic conditions, you can choose more professional competitive swimming as an introduction. Of course, the study time is longer and the study is more difficult.

If you want to swim quickly in the water first, choose a simpler enlightenment frog.

Freestyle.

Freestyle has several advantages over other strokes:

1. More suitable for long-distance swimming.

2. The fastest.

3. There are relatively few requirements for physical fitness.

4. It has a more positive effect on joint activity and exercise.

Swimming, as an aerobic exercise, can reduce fat.

But the premise is to achieve the aerobic goal. Simply put, if you don’t feel tired after swimming, the effect of reducing fat can be imagined.

If you want to lose weight by swimming, here are some suggestions:

1. Exercise should be intense. You swam 1000m a year ago, and now you swim 1000m, so this exercise intensity can’t stimulate your fat.

2. Exercise needs persistence. If you only swim once or twice a week, no exercise can achieve good fat reduction.

3. Don’t overeat after exercise. Almost everyone has a feeling of hunger after swimming. After practicing, you will eat like crazy, and no one can lose weight.

Because swimming is an exercise in water below body temperature, the human body itself uses fat to help keep warm.Therefore, if you simply want to reduce fat with a large base, I suggest you change to a sport with faster effect and sweating; If you just want to lose weight and keep fit, swimming must be a good choice.

tag

That’s all for this issue. As summer approaches, I hope more people will take part in swimming. Instead of wondering how long it will take me to learn to swim, I’d better ask myself: How long am I going to love swimming? I’ll see you at the pool ~

The beauty industry has always relied on a steady stream of products to attract consumers. However, the epidemic is causing the supply chain and product testing to lag, which makes it more difficult for them to launch new products.

New york, USA-The "latest products" area on the shelves in the beauty shop may soon be empty.

Beauty brands and retailers have been relying on a steady stream of products to attract consumers to shop in stores and e-commerce platforms. However, many so-called "new products" were actually put into production before the epidemic. Experts believe that once these products are exhausted, the negative impact of the epidemic will be highlighted, and every link in the supply chain of the beauty industry will have different chaotic problems such as shortage of key raw materials, insufficient packaging and even blocked research and development process.

Therefore, although major brands may be eager to launch new products suitable for the epidemic situation, such as moisturizing cream for "mask skin" and skin care products that can soothe the face or reduce blue light damage, it is not easy to ensure that the supply chain can keep up. Many companies are focusing on maintaining the inventory of existing products.

"From the perspective of product development and release, the growth momentum of beauty cosmetics has definitely weakened compared with the past few years," said Daniel Granatell, managing director of Grant Industries, which develops and produces personal care products.Most brands are still producing core or popular products, and their focus is on continuing existing products rather than developing new products or innovating growth models.. "

Many beauty companies have postponed the launch of new products until 2021, which means that the most eye-catching new product launch will miss the key year-end shopping season. Jessica Richards, founder of Shen Beauty, a retailer focusing on emerging luxury brands, said that most of the press conferences she had hoped to hold had been cancelled.

During the epidemic, brands that want to introduce new products to consumers have to be creative. Researchers are looking for new ways to use raw materials from traditional formulas, such as adding a new fragrance full of "tropical flavor" to the existing shower gel series to help realize the creativity of new products. It is also one of the ways to introduce "new" products without purchasing new raw materials, updating product formulas or expanding products in existing series.

Other companies are changing the way they produce and package their products. Retrouvé, a skin care brand, chose to break away from convention. When Dermal Defense hand cream was launched, the cumbersome outer packaging was cancelled and the inner packaging was streamlined. "My new slogan is,’ Get things done,’" said Jami Morse Heidegger, co-founder of the brand.

Problems in the supply chain

Forced isolation and consumer demand for sterilization products have had an unparalleled impact on the beauty supply chain. Take packaging containers as an example: Charlene Valledor, chairman and product development director of SOS Beauty, a beauty brand incubation company, said that when all retailers are rushing to put hand sanitizer into production, there will be a shortage of containers such as pressing pumps and bottles for other products.

The epidemic also affected the growth and cultivation of many raw materials.

“The COVID-19 outbreak this spring disrupted the cultivation of many special raw materials for high-performance beauty products., "said Jared Reynolds, a beauty chemist who is also the founder of Zenagen and Actiiv, the anti-hair loss brands. He explained that this has had a domino effect on companies that now find themselves forced to strive for a stable supply chain, especially those suppliers from China and Europe, who are facing a longer delivery cycle due to travel restrictions and related import and export agreements.

For example, some of Zenagen’s products use a green tea extract from Asia. "Because the supplier was forced to stop production, it could not continue production. When the factory resumed processing and manufacturing, its production cycle was tripled, "Reynolds said.

Other links in the manufacturing industry have also been affected. Earlier this year, Joanna Vargas had trouble purchasing accessories for her face massager under the skin care brand of the same name. She had to postpone the product release for three months to avoid looking for a new supplier.

"Relationships with manufacturers, suppliers and partners are very important to us," she said. "We don’t want to turn to new business partners just to speed up profits for a month or two."

Try to get through it

Big brands have certain advantages in today’s supply chain shortage. They have a better ability to pay higher raw material prices, and they can jump to the forefront of manufacturers’ cooperation teams by placing a large number of orders.

In addition, they usually have more opportunities for cooperation. Christine Hall, vice president of R&D department of Estée lauder, said that Aveda, a subsidiary of the group, has arranged a new product release plan for the next 12 months, which also gives the brand more room for manoeuvre. She said, "We are also striving for more time to finish the work", so that Aveda can ensure the orderly development of new products.

But small brands are also more flexible to some extent. When Seen, a hair care brand, couldn’t get enough press pumps for its shampoo and conditioner, it temporarily decided to switch to a different color press pump. A larger company may not be able to make this change so soon.

Brands that have completed their purchases at home have also gained the upper hand. Bradley Ryan, founder of men’s beauty brand Undercover Man, attributed his recent success to the use of pomegranate oil and beeswax purchased locally.

Credo also doesn’t think its new product launch activities will decrease in the next few months. This is partly because this retailer only sells "clean" and sustainable beauty brands, which Annie Jackson, its founder and chief operating officer, calls "flexible" because these brands don’t rely on fancy packaging design, and they "tend to purchase in China, without considering long-term transportation delivery and other constraints from the epidemic".

The number of tests is reduced.

Product testing is another obstacle that needs to be overcome. Products must meet the safety standards before they are officially listed. For example, the slogan "90% of product users think their fine lines have decreased" requires clinical trials, but the efficiency of these tests has slowed down due to the outbreak of the epidemic.

This means that brands will have to wait longer to publicize the benefits of their new products, which is particularly difficult for the skin care industry.Because many brands take the commitment to quality innovation as their key selling point.

"Most third-party testing institutions have been closed, and the testing institutions that are still operating in the United States need to queue up for a long time to make an appointment," said Tamerri Ater, product development director of Versed Skin Care. "We have found a spare testing institution and tried our best to shorten the testing cycle accordingly."

The above problems also caused Ron Robinson, a cosmetics chemist and founder of BeautyStat, to feel "frustrated" when he launched a new product in early June and failed to conduct clinical trials to prove its efficacy.

"Before the release of the product, we have completed the safety test and internal performance test, so we know that the product is safe and effective ….. but we also hope to be verified by a third party," said Robinson, who completed a four-week test for 31 subjects at the end of July, and wrote in the information description of the product: "90% of crow’s feet, fine lines and wrinkles seem to have improved."

A turning point is coming.

Experts believe that with the epidemic under control, most of these problems can be solved. The sales boom of some products may also stimulate investment in resources needed to accelerate supply chain development.

Dan Langer, chairman of the hair care brand R+Co, said: "People’s interest in health, personal care and sustainability is rising again, and I think we will see real innovation in this industry next year."

Vargas predicts that the slowdown in R&D business will eventually recover, and before that, the whole industry can barely survive. "Now is not the time to introduce new products on a large scale for marketing," she said. "I think products with good quality, high efficiency and simple use will eventually stand out."
