On September 6th, 2022, at the autumn conference of Mate50 series and new products in the whole scene held by Huawei, the new pure electric vehicle AITO Wenjie M5 EV, which was deeply empowered by Huawei, was officially released. Thanks to the HarmonyOS intelligent cockpit, the intelligent level, endurance and comprehensive performance of the M5 EV have evolved in an all-round way, aiming to bring consumers the ultimate carefree smart travel experience. As a part of the HarmonyOS intelligent cockpit, Xiaoyi has also been upgraded again, bringing a new and more humanized voice interaction experience to car owners with continuous technological innovation and functional optimization.

Intimate service will be upgraded, and car xiaoyi will be a travel assistant who knows you better.

Traditional voice assistants often need users to send voice instructions in one direction before they can provide services. Xiaoyi, the intelligent assistant of AITO’s M5 EV, can not only actively provide services through wisdom perception, but also add five functions, from reminding to start the power-saving mode, charging reminder, charging station inquiry and screening to easy navigation and getting off at complex locations, providing car owners with all-round intimate services such as getting on, driving and getting off, making travel smarter and more enjoyable.

Super power saving mode reminder：In view of the emergency that may occur during driving, Xiaoyi has added the function of "Super Power Saving Mode Reminder", which is the first in the industry. Specifically, when the vehicle is in a low battery, Xiaoyi will take the initiative to broadcast "The battery is low, do you want to turn on the super power-saving mode?"; After the user agrees to turn it on, it will voice again to remind that "the torque and maximum speed of the vehicle will be limited after turning on the super power-saving mode. Are you sure to turn it on?" After getting the second confirmation from the user, Xiaoyi will switch the vehicle to the super power-saving mode to help the owner drive with peace of mind.

Voice charging service：When you want to charge the car but can’t find a suitable charging station, the user can wake up Xiaoyi by voice to quickly query and filter. After the voice wakes up Xiaoyi, the user can say "Filter Fast Charge/Slow Charge", and Xiaoyi will filter out the list of nearby fast charge/slow charge charging stations according to the voice instruction, and the user can go directly to the charging station he wants to go according to the planned route of Xiaoyi. The whole process of inquiry and screening needs no hands-on, and the voice control skill is easily realized, which greatly improves the driving convenience.

Intelligent voice charging reminder：For users who often charge their cars in a fixed period of time, Xiaoyi can intelligently learn and remember the user’s habits, and when the user does not charge the car according to his habits, he will take the initiative to remind "I suggest you charge according to your charging habits" and respond quickly and actively; When the temperature drop may affect the car’s power, Xiaoyi will also perceive and broadcast the weather information in time to remind users to charge in advance-"The temperature will be low tomorrow, so it is recommended to charge today".

Easy navigation in commonly used complex places：whenWhen the frequented places are too complicated and navigation is troublesome, clever and capable small arts can also help. It can select the destination information and plan the route to the destination according to the user’s historical preference-that is, after the user has visited a complex location for three times, Xiaoyi can directly locate the specific location when the user navigates to this address next time, avoiding the search for complex locations and easily improving the travel efficiency.

Xiaoyi reminded me：Always forget to bring the necessary items after getting off the bus. In order to avoid running back and forth in a hurry, the user can set the get-off reminder for Xiaoyi voice in advance. For example, when you get on the bus, you say "Xiao Yi Xiao Yi, remind me to take an umbrella in the trunk when you get off the bus". When you judge that the user gets off the bus according to the behavior intelligence such as hanging the P file and opening the door, Xiao Yi will remind you in time: Please remember to take an umbrella in the trunk.

In addition to these intimate functions, the car-mounted Xiaoyi can accurately judge and respond to voice commands from the main driver, the co-driver and the rear row through "four-tone zone recognition", communicate with the owner more smoothly and naturally through "full-duplex continuous dialogue", and operate the text, buttons and function options of the car interface at any time through "full-interface visual speaking". The smarter you use Xiaoyi, it is expected that through continuous function upgrade, it will bring users a more humanized car voice service experience and redefine the new way of smart travel.

Special feature of 1905 film network According to foreign media reports, a famous French actor, director and producer died on April 21st local time at the age of 80.

Jacques perrin is a legend of French films.

As an actor, at the age of 25, he won the Golden Lion Award for Best Actor at Venice Film Festival with the film "Half a Man".

Stills of Half a Man

As a producer, his works have been nominated for the Oscar for Best Foreign Language Film for many times.

Based on the real assassination

Let behan be nominated for the Oscar as a producer for the first time

As a director, his nature documentaries and other epic works, which started shooting in 1980s, made him a documentary master in the hearts of global audiences, and also earned him the reputation as a French national treasure director.

To many people, jacques perrin’s artistic life seems to be open.He was born in France in 1941. Because his father was the stage supervisor and his mother was an actor, he lived in the theater since he was a child. Started in movie master at the age of six.Marcel CarnéGuest role in "Gate of the Night".

"Night Gate" screen

At the age of 20, he was admitted to the National Paris Institute of Advanced Theatre Arts and received professional training. In 1960, he took the leading role in the film of the famous Italian film director Valerio Surini, and made his mark in the film industry.

Today, people can’t take their eyes off him. However, at this time, jacques perrin has a broader ideal: to find broader freedom in movies.

In the days surrounded by flowers and applause, jacques perrin never stopped reflecting, just like his creative attitude. Because behind the open life, he also experienced the loss that outsiders can’t imagine.

In 1970, at the age of 29, jacques perrin gradually retired from the background and tried to be a producer. The number of films was amazing. Up to now, we are familiar with many French films, such as Children of Lumiere, Long Engagement and Perfume. You can not only find his figure in these films, but also find his name in the list of titles and producers.

Play the role of adult Pierre in Spring of Cowboy Class.

But he also experienced many box office fiasco. Especially in 1976, because of heavy debts, he was once forced to interrupt his production work.

Stills of "The Desert of Tatars"

It was Giuseppe tornado who made his name appear on the Oscar shortlist for best foreign language film in 1988. He played Duo Duo as an adult.

There are many middle-aged people in Paradise Cinema.

When many young people leave their hometown, they bid farewell to Alfredo. This grandpa’s line has made many people cry.

"Whatever you want to do in the end, love it!"

This seems to be the rule that jacques perrin abided by all his life. In 1989, the production of "Monkey Family" made him really shift his focus to the theme of natural ecology, which also marked the rise of animal movies in France.

Since 1994, jacques perrin has successively released the trilogy of "Heaven, Earth and Man": "Migrating Birds", with migratory birds, insects and mountain people as the main characters, which has aroused widespread concern.

Working photos of Migrating Birds

During most of his life devoted to nature documentaries, he flew over five continents with pilots and scientists for Migrating Birds, and crossed the Pacific Ocean and the Atlantic Ocean. The Himalayas and the Sahara Desert were also their stops. I also lost everything for "The Ocean".

Work photos of Ocean

The documentary "Ocean", which took a team of 400 people seven years and cost 75 million dollars, is the most expensive documentary in history. The film has shot more than 100 marine creatures, which not only shows the law of natural selection, but also tells the life of harmonious coexistence among marine creatures. Different from the common nature documentary, it records the vivid images of marine life that are little known and have strong feelings.

Jacques perrin has been preparing for Ocean for more than two years and filming for more than four years. He has designed the most advanced instruments to see the ocean with the vision of fish. He raised money while filming, and even had to resort to corporate sponsorship from all over the world to seek the support of publishers, film organizations and charities from all over the world. Later, the film overspent 9 million euros, which later became a huge debt on him.

In the end, The Ocean not only won the best documentary in César Awards, but also became the highest-grossing documentary in history.

Jacques perrin’s shooting technique of natural and ecological documentary has reached a fantastic level by the time of this film. He vividly reproduces the nature of the universe from three aspects: three-dimensional shooting of space, synchronization of sound and picture, and impersonal objective recording, bringing the audience into the natural ecology and immersing them in the movie dream.

In the dream, flocks of birds fly by us, and they will be deeply stared at by the cute sea lions.

"If the earth one day, only ourselves. Is there anything sadder than this? Our film is not the kind that always has a sequel, or we hope that the audience can experience the beauty of nature in the cinema! "

In 2015, jacques perrin was included as a member of the French Oceanographic Association, and worked closely with the world ecologists as a French eco-filmmaker, using the power of movies to awaken human beings’ attention to the earth’s ecological problems.

In China, the documentary directed by jacques perrin is the most familiar foreign documentary film, especially regarded as one of the compulsory courses of aesthetic education by family audiences. His Spring of Cowboy Class and Paradise Cinema have also influenced a generation of China filmmakers.

In memory of the French filmmaker familiar to the audience in China, the film channel will be held at:

At 8:50 on April 23, the documentary "Ocean" directed by jacques perrin was broadcast;

At 22:20 on April 25th, the classic movie Paradise Cinema starring jacques perrin was broadcast.

On April 30th, at 17:20 pm, World Movie Journey will launch a special program in memory of jacques perrin, so stay tuned!

　　CCTV News:The geostationary communication satellite represents the development level of a country’s satellite communication. It is an important resource that constitutes the foundation of the information superhighway and an important embodiment of a country’s comprehensive strength and technical level.

　　People who often travel in China know that mobile phones and notebooks can’t get on the Internet on flying planes and ocean-going ships. Similarly, on high-speed high-speed trains, mobile phone signals are intermittent. However, with the development of a new generation of communication satellites in China, full coverage of online chatting, ocean-going video entertainment and remote mountain signals will become a reality.

　　China’s independent research and development technology breaks the monopoly of foreign air communication

　　Maritime video will no longer be a dream.

　　On April 12, 2017, China successfully launched the Shijian-13 satellite in xichang satellite launch center using the long march 3b. After completing the on-orbit test, the satellite was named Zhongxing-16.This is the first Qualcomm communication satellite in China, with a total communication capacity of over 20G, which truly realizes the broadband application of autonomous communication satellites.

　　Zhang Wei, Senior Engineer of the Fifth Academy of Aerospace Science and Technology Group:The development of Qualcomm measurement technology represents that we are now on the ground, and you can use our satellite to realize video. Originally, only one voice communication function can be realized. Now we can video, so there is still a great application direction, that is, our aircraft. This is the first time that China has used Ka-band broadband communication technology on communication satellites.

　　Satellite capacity is actually like a highway. The original C-band and Ku-band capacity of communication satellites can only accommodate two cars at the same time, and the cargo they can carry, that is, information and data, is limited. However, the capacity of Ka-band satellite is much larger, it can drive 10 or more cars on the road at the same time, and the amount of information and data it can carry far exceeds that of other frequency bands.The breakthrough of this technology means that broadband internet access can be realized anytime and anywhere through communication satellites in the future, especially in areas that cannot be covered by ground communication networks, as well as on aircraft, high-speed rail, ships and other means of transportation.

　　Zhang Wei:Now everyone on the plane knows that communication can’t be realized. After the technology of HTS (Qualcomm Communication Satellite) is popularized in the future, we can also realize our communication on the plane based on satellites, including high-speed rail, ships and so on. HTS is a very popular application direction.

　　Zhang Wei told reporters that relying on Qualcomm’s satellite communication technology, a satellite broadband communication network will be built in the future. By then, no matter whether you are in an airplane at an altitude of 10,000 meters, a high-speed high-speed train, or a ship in the vast sea, or a deserted desert, deep mountain or island, you can browse the network and make video calls at high speed.

　　At present, the Fifth Academy of Aerospace Science and Technology Group has developed satellite mobile communication terminal products for outdoor, high-speed rail, ships and other aspects based on the Qualcomm satellite of Zhongxing 16. The original satellite communication terminals, limited by satellite design, are relatively large in size, and are generally installed on buildings or large vehicles.Now, relying on Qualcomm satellite, the terminal receiving device of communication satellite can be miniaturized, and ordinary household SUV can be installed.Zhang Ge, a senior engineer of the Fifth Academy of Aerospace Science and Technology Group, demonstrated a portable satellite broadband communication system for reporters. This system has the function of one key to the satellite, and can quickly connect the network when the ground communication network is damaged or interrupted in the earthquake-stricken area.

　　In addition to this portable satellite broadband communication system, the team led by Zhang Ge is still developing satellite broadband communication systems for high-speed trains and ocean-going ships.

　　Zhang Ge, Senior Engineer of the Fifth Academy of Aerospace Science and Technology Group:At present, our equipment supports more than 500 people, that is, if you install such a device on a luxury oil tanker, all the people on board can access the Internet directly via satellite by taking your ordinary mobile phone and connecting to the ship’s WIFI.

　　Combining technical test with demonstration application, Zhongxing-16 carried out high-speed laser communication test on the geosynchronous orbit satellite for the first time, with the highest speed of 2.4 G.. Satellite laser communication has the advantages of large communication capacity, long transmission distance and good confidentiality. If the test is successful, it marks that China has reached the international advanced level in this field.

　　On August 6th, 2016, China successfully launched Tiantong-1 satellite 01 in xichang satellite launch center, which is the first star of China satellite mobile communication system, also known as the "China version of maritime satellite", and its successful launch marks that China has entered the "mobile phone era" of satellite mobile communication.

　　After the Wenchuan earthquake in 2008, the ground communication network in the earthquake zone was completely paralyzed. At that time, China did not have its own mobile communication satellite system, so it could only rent foreign satellite phones for earthquake relief. The international mobile satellite system has formed a number of global or regional mobile communication systems, which are not only widely used in personal communication, ocean transportation, offshore fishing, air passenger transport and other fields, but also can realize barrier-free communication and determine the location in the case of natural disasters such as earthquake, flood and frost. After the Wenchuan earthquake, Tiantong No.1 was established.

　　The reporter learned that the technical indicators and capabilities of Tiantong-1 satellite have reached the level of international mainstream mobile communication satellites, and it has completely independent intellectual property rights. In particular, Tiantong-1 satellite has solved the technical problem of deploying an oversized antenna, making the satellite telephone terminal used on the ground more miniaturized and mobile.

　　The selfless dedication of several generations of researchers has been passed down from generation to generation.

　　Make China’s satellite industry from scratch. From lagging behind to leading

　　In recent years, our communication satellites have been successfully launched and put into use, covering the cutting-edge technologies and applications in the development of communication satellites, such as broadcast and television live broadcast, Qualcomm broadband satellite, mobile communication satellite and data relay satellite. Looking back, when we started to develop satellites, we were not only poor. Moreover, the foundation is weak. Under such conditions, our researchers insisted on self-reliance and selfless dedication, and finally embarked on a road of research and development of China communication satellites. Although this road was not smooth, it also experienced setbacks and hardships.

　　In the exhibition hall of the Fifth Academy of China Aerospace Science and Technology Group, real products from Dongfanghong-1 to Dongfanghong-4 satellites are displayed, which have witnessed the development of communication satellites in China.

　　Dongfanghong-1 was China’s first artificial earth satellite developed by the older generation of space scientists and technicians through self-reliance under the conditions of poverty and weak economic and technological foundation at that time. Due to the limitation of technical level at that time, it did not have communication function.

　　Zhang Wei, Senior Engineer of the Fifth Academy of Aerospace Science and Technology Group:After the success of this satellite, it actually created a precedent for our country’s artificial earth satellite, but its significance only reflects from scratch, so our satellite will be put into use after all.

　　After the successful launch of Dongfanghong-1, in order to make the communication satellite truly practical, the older generation of space science and technology personnel, represented by Sun Jiadong and Qi Faren, established the belief of "developing China people’s own communication satellite on their own". After nine years of hard work, Dongfanghong-2 communication satellite was finally developed successfully. On April 8, 1984, Dongfanghong-2 experimental communication satellite was successfully launched, making China the fifth country in the world to independently develop and launch geostationary orbit satellites.

　　Constrained by the technical level of electronic component development and material science research at that time, Dongfanghong-2 satellite had a small load and a short service life. The C-band transponder of the satellite had only two channels, while the C-slope transponder of the international advanced communication satellite had reached 24 channels at that time, and its service life was as long as ten years.

　　Zhang Wei:At that time, the power it could provide was very small, because there were so many solar cells, so it could provide so much power. Therefore, at that time, the on-orbit life of our country’s communication satellites was relatively short, that is, five years, and the effective power it could provide was very low, so the so-called transponder number was just a few transponders.

　　The main load of communication satellite is transponder, and one transponder can transmit more than ten sets of standard definition TV programs. The greater the load of communication satellite, the more transponders, which means that more radio and TV programs can be transmitted and more communication capacity can be provided. Zhang Wei told reporters that because Dongfanghong No.2 could not meet the needs of customers at that time, there was also a debate about "buying stars" or "making stars" in China. Under the circumstances at that time, astronauts had no choice but to develop Dongfanghong-3 satellite according to the international level at that time under the condition of weak technical foundation and poor facilities.

　　Zhang Wei:Dongfanghong-2 is a spin-stabilized satellite. By Dongfanghong-3, we have a three-axis stabilized satellite. With the adoption of the solar wing, the technology has a great leap forward, and we can only inherit about 20% of the technical foundation of Dongfanghong-2, and the remaining 80% is based on the independent innovation of our astronauts in China.

　　From the national project in 1986 to the successful launch of Dongfanghong-3 satellite in 1997, researchers have solved hundreds of technical difficulties in 11 years, gnawed down more than ten "hard bones" and experienced the pain of the first satellite launch failure. Dongfanghong-3 satellite not only achieved a leap in the development technology of communication satellites in China, but also provided a highly reliable communication satellite platform for China’s space industry.

　　In 2000, Dongfanghong-4, aiming at the international first-class level, began to be developed. The design life of the satellite platform was increased to 15 years, and the number of transponders carried was increased to 52. At that time, the market goal of Dongfanghong-4 communication satellite was not only to occupy the domestic market, but also to go out and seize the international market.

　　While researching and developing the communication satellite platform of Dongfanghong-4, they are also exploring the market of Dongfanghong-4. In May 2002, they signed a purchase order contract for Xinnuo-2 satellite with Xinnuo Satellite Communication Co., Ltd.; In May, 2004, he participated in the bidding for the whole satellite development and launch project of Nigeria Communication No.1 satellite, and stood out from 21 companies including the United States, France and Britain, and won the bid successfully.

　　Zhang Wei:Dongfanghong-4 satellite, its weight reached 5 to 5.5 tons, and its load capacity reached about 600 kilograms. This level was actually at the same level as the international advanced level at that time, so through Dongfanghong-4, we actually realized a transformation process from following to running together.

　　In 2010, focusing on the demand of high-power communication satellites in the next 20 years, a new generation of Dongfanghong-5 satellite with high load, high power, long life and expandability began to be developed. At the same time, the Fifth Academy of Aerospace Science and Technology Group is also tracking the most advanced technology in the world and expanding the technical level of the original satellite platform. In order to improve the payload of communication satellites, they have to make the electronic system smaller and smaller.

　　Gong Jianglei, deputy director designer of the Fifth Academy of Aerospace Science and Technology Group: These products are actually a hardware product based on the integrated electronic system on our entire communication satellite.Now these four products have actually replaced more than 20 previous products. The previous products were relatively large in quantity and volume, and we have reduced them by about 50%, which is also a relatively leading level in the whole world.

　　It is an inevitable choice for the Fifth Academy of Aerospace Science and Technology Group to follow the world’s leading technology and achieve technological transcendence in some technical fields. After graduating from Ph.D. in 2008, Chen Yue came to the Fifth Academy of Aerospace Science and Technology Group to be responsible for the control and promotion of communication satellites. Just after working for more than two years, he proposed to the institute the research on electromagnetic propulsion of communication satellites without working medium, which was still controversial at that time.

　　Chen Yue, deputy director designer of the Fifth Academy of Aerospace Science and Technology Group:Everyone’s main doubt is that this technology may be scientifically researched and developed in engineering before it is fully explained. Is it risky or is there a principled error? This is the main controversy.

　　Communication satellites in space need to adjust their attitude and maintain their orbits, so satellites will carry a lot of propellant. The traditional chemical propulsion method is to generate thrust by propellant oxidation. At present, the electric propulsion method used in satellites is to ionize the carried working medium gas, and then spray the plasma to generate thrust. Both of these propulsion methods need to carry working medium, that is, propellant and gas.

　　Chen Yue:Figuratively speaking, these liquids or gases stored in the tank, once these working fluids are used up, the engine can no longer be used, and its life is up. And our current propulsion mode, this electromagnetic propulsion, is that as long as there is electricity, as long as the equipment can work normally, it can work and generate thrust.

　　There is no technology and experience to learn from, and there is no reference to any foreign materials. This technology is in the initial stage of technical experiment at home and abroad, and Chen Yue and his team are facing great challenges.

　　In order to encourage young people to innovate, the Fifth Academy of Aerospace Science and Technology Group set up a special fund for R&D and a special fund for doctoral growth to give financial support. Moreover, the core R&D personnel were not assessed for three years, and they were given strong support in personnel and experimental equipment to ensure that they concentrated on technical research.

　　Chen Yue:Through the independent research and development fund of the Science and Technology Committee of our institute and the independent research and development fund in our institute, we can support us, so that we can focus on this matter without worrying about the guarantee of conditions. It can be said that this is like an incubation. If there were no such incubation conditions at the beginning, we would not have this progress.

　　The reporter learned that at present, many key technologies of Dongfanghong-5 satellite platform, which represents that China’s communication satellites have reached the international leading level, have made major breakthroughs and need to be verified in orbit. Dongfanghong-5 platform has a total satellite power of 30,000 watts, a payload of more than 2,000 kilograms, and 120 transponder circuits, and some technical indicators exceed the level of developed countries. Most of the products on Dongfanghong-5 platform can be truly localized, independently controllable and no longer dependent on imports.

　　Half-hour observation: Aerospace, China’s brightest "business card"

　　From the first Dongfanghong-1 satellite to the world-leading Dongfanghong-5 satellite, the development of China’s communication satellites has gone from scratch, from following to running in parallel.

　　The development level of communication satellites represents a country’s scientific and technological level in the field of space science and technology, and it is also an important embodiment of a country’s comprehensive strength. Although we have experienced failures and setbacks in the development of communication satellites, we have finally been at the forefront of international communication satellites in just a few decades.

　　This is the result of the silent and selfless dedication of the vast number of aerospace science and technology workers, and it is also a continuation of the spirit of the older generation of astronauts.

　　The idea of coarse cereals has a long history. As early as more than 2,000 years ago, in the book Huangdi Neijing, the principle of balanced diet was put forward, in which coarse cereals refer to "rice, adzuki beans, wheat, soybeans and millet", which shows that coarse cereals have played an important role in diet since ancient times. So, what kinds of grains do miscellaneous grains include?

　　Generally, it refers to cereal crops other than rice, wheat, corn, soybean and potato, in which cereal grains mainly include sorghum, oats, millet, quinoa, buckwheat, etc., and bean grains mainly include mung beans, adzuki beans, kidney beans, peas, chickpeas and lentils.

　　Compared with polished rice, which nutrients of miscellaneous grains are more abundant?

　　Miscellaneous grains are rich in protein, dietary fiber, vitamins, minerals and a variety of bioactive substances, with high nutritional value. Compared with polished rice, miscellaneous grains are richer in protein, insoluble dietary fiber, B vitamins and trace elements such as calcium, magnesium and iron.

　　1. protein

　　Protein is rich in coarse cereals, especially leguminous coarse cereals, and protein is as high as 20%, which is a good source of plant protein. Cereal protein generally lacks essential amino acids — — Lysine, while miscellaneous beans contain high lysine. When they are eaten together, they can make up for the shortage of cereals and improve the overall utilization rate of protein.

　　2. Dietary fiber

　　Miscellaneous grains are also rich in dietary fiber, which can not only increase satiety, control weight and lose weight, but also enhance intestinal function and improve constipation, which is also very helpful for lowering blood lipid and protecting blood vessels.

　　3. Vitamins and minerals

　　Coarse cereals are rich in B vitamins, and the contents of minerals such as calcium, iron and zinc are much higher than those of refined rice. These nutrients play a very important role in maintaining the normal function of the body. For example, B vitamins generally participate in various physiological processes in the body in the form of coenzyme, which is an indispensable substance to promote metabolism in the body and convert sugar, fat and protein into energy. Calcium can form a strong skeleton to support the whole body and protect the heart, lungs and teeth. Iron is the raw material of cells and participates in the synthesis of hemoglobin, myoglobin and some enzymes in the body. Zinc can promote growth and tissue regeneration, promote vitamin A metabolism, and participate in immune function.

　　4. Other plant active ingredients

　　Coarse cereals are also rich in phenolic compounds, such as phenolic acids, flavonoids and phytosterols, which have strong antioxidant biological activities.

　　In addition to reducing cardiovascular diseases, what are the effects of miscellaneous grains?

　　1. Reduce the risk of cardiovascular metabolic diseases.

　　Studies have shown that a higher intake of miscellaneous grains is associated with a lower risk of diabetes and ischemic stroke. For every 100g/day increase in intake of miscellaneous grains, the risk of diabetes and ischemic stroke is reduced by 14% and 13% respectively.

　　2. Regulate blood sugar

　　Miscellaneous grains contain many plant active ingredients that can reduce blood sugar concentration, including polysaccharides, flavonoids, dietary fiber and so on. These plant active ingredients are helpful to delay the digestion and absorption of food, improve insulin sensitivity and glucose metabolism, and thus play a role in preventing or slowing down the increase of blood sugar in the body.

　　3. Regulating blood lipids

　　Coarse cereals are rich in dietary fiber and polyphenols, which can reduce the plasma cholesterol level by reducing the absorption of cholesterol in the diet and promoting the excretion of cholesterol, or by slowing down or reducing the fat absorption.

　　4. Promote intestinal health

　　The rich dietary fiber contained in coarse cereals can hold water, adsorb water molecules in the intestine, increase the volume of feces, promote food residues or toxins to move in the intestine and excrete them quickly, which is helpful to prevent constipation and reduce the risk of rectal cancer. The plant polysaccharides contained in it are decomposed and utilized by intestinal flora in the intestine, and fermented to produce short-chain fatty acids, which provide energy for intestinal epithelial cells and protect the intestinal barrier.

　　5. Antioxidant activity

　　Coarse cereals are rich in natural antioxidants, such as phenols, unsaturated fatty acids, sterols, phytic acid, vitamin E, etc., which can help the human body to better resist free radicals and delay aging.

　　How to open the correct posture of eating miscellaneous grains?

　　1. The intake should be appropriate

　　China residents’ dietary guidelines recommend that 50-150g of whole grains and legumes should be consumed every day, among which whole grains and legumes are the main sources of whole grains and legumes.

　　2. Eat with thickness.

　　Although the nutrition of miscellaneous grains is good, it cannot completely replace polished rice flour. Because of the high content of dietary fiber and resistant starch in miscellaneous grains, it will cause certain pressure on the gastrointestinal tract. Especially for the elderly, children and people with weak digestive function, the inedible dosage is too large. You can eat coarse cereals and polished rice flour together, and gradually increase the proportion of coarse cereals in the staple food according to your own physical reaction and taste acceptance. Healthy adults can eat 1/3 to 1/2 of the staple food every day.

　　3. Fine coarse grains and diversified cooking methods.

　　Coarse cereals are hard in texture, so they can be soaked for several hours before cooking to fully absorb water, and at the same time, anti-nutritional factors such as phytic acid and saponin can be removed by soaking. The miscellaneous grains rice or porridge with soft and rotten taste can be made by using the miscellaneous grains rice function of electric rice cooker or pressure cooker, and it is also a good choice to make miscellaneous grains soybean milk or miscellaneous grains rice paste with soybean milk machine and wall-breaking machine.

　　4. Gluten and beans are mixed and varied.

　　The composition of vitamins, minerals and other nutrients contained in different miscellaneous grains is quite different, so it is more nutritious to eat them together. When cereals and beans are eaten together, amino acids can complement each other and the overall utilization rate of protein can be improved.

　　Afraid of cardiovascular disease? These foods will be late if you don’t eat them.

　　Cardiovascular disease is the leading cause of death in the world. According to the statistics of the World Health Organization, nearly 18 million people worldwide die of cardiovascular diseases every year, accounting for more than 30% of the total deaths. Three points move, seven points eat. Many diseases are eaten diseases, and cardiovascular diseases are no exception. If you don’t eat right, the chances of high blood pressure, myocardial infarction and stroke are much higher than those who "eat". So, what is the right way to eat? Let’s take a look at a recent research conclusion published in the European Heart Journal, which is a joint research result from Fuwai Hospital in Beijing and McMaster University in Canada. If you want to help your parents and your friends with healthier cardiovascular system, prepare a small notebook quickly.
