Life is just a process, even a fleeting process, even as short as a meteor disappearing in the sky, so shouldn't we make life more brilliant? There is only one life, and if you lose it, you will never have it again. We should cherish it.
So how do we keep healthy? First of all, we must have an optimistic attitude. Mentality has an important influence on one's study, life and growth path. A positive and optimistic attitude will make a person study more easily, live happier, be indifferent to wisdom, and be quiet and far-reaching.
Secondly, ensure adequate rest. Rest can help people relax their nerves and recover their physical strength, which is very important for human health. After a busy day, you will feel tired and tired, and you need to restore your spirit and physical strength to meet the next day's life. When you sleep, your body will adjust itself, so that you can greet the new day with energy.
Then insist on proper exercise to maintain a balanced nutrition. Insisting on moderate exercise has many benefits to health, which can not only improve the quality of sleep, speed up metabolism, improve the heart and blood circulation system, but also relieve irritability. People need to ingest various nutrients every day in order to maintain the normal metabolism and function of the body. The effect of diet on health is a long-term result. We should pay attention to food diversification, eat more vegetables, fruits and grains, choose a low-fat and low-cholesterol diet, and avoid smoking and drinking.
Watching life walk in your hands and mine, please take good care of it; Life carries too much beauty, please take it seriously. Life is today. Only by seeing today and cherishing life will everything exist.
Let's cherish life together, cherish life. Look at everything with a healthy, full and optimistic mood, and life will certainly become very beautiful.
2. The nutrition improvement plan helps me grow. Dear teacher:
Hello! I take the liberty of writing this proposal for you. Please take time out of your busy schedule to have a look. You are the headmaster of the school and have a lot of things to do every day. You have worked hard for us and injected enthusiasm into the school. Keep the school in good order.
However, you neglected the important place on the fourth floor-the library. It makes it full of knowledge forget its mission and temporarily fall into a deep sleep. In the sacred school, the door of knowledge is closed. Do you know that?/You know what? How many eager eyes looked at the "unreachable" bookshelf through the window. Do you know all this? I remember the last time you asked us to clean the library, it was full of dust. Hardly had I finished cleaning a table when the rag turned black. Such a treasure house of knowledge built for classmates is willing to be submerged in the muddy yellow dust? Many things that shouldn't have happened in school have also developed into "bullying at every turn": this article was edited by studying abroad together and reprinted from studying abroad together.
1, many students blindly read bad books and periodicals that are harmful to their growth because they can't tell the pros and cons of books;
Finish your homework during the break, because there is nothing to do, and it is dangerous to be crazy.
3. Because I didn't form the habit of reading when I was a child, many people just accepted the knowledge taught by the teacher mechanically and didn't study after class.
In view of the above three points, we sincerely make the following suggestions to you:
1, open the reading room as soon as possible, buy health books and periodicals, and increase intellectual reading materials such as "100,000 Why" and "Knowledge Encyclopedia". And it is best to change books regularly to prevent students from being bored;
2. Let two people act as "librarians" to prevent the phenomenon of tearing and stealing books;
After each semester, we hold "Reading Club" and "Knowledge Competition" to gain knowledge, cultivate sentiment and have fun.
Please adopt the above suggestions to add an antique book to the campus. Please forgive me if there is anything wrong.

3. Good habits help me grow up and develop good eating habits (1000 word composition). I need good habits to grow with me (2)
When I was growing up, I had many good habits.
I have a good habit of going to bed early and getting up early, so I have never been late. And in the first grade, the head teacher, Mr. Zhao, gave me the key to our class. Because I come early every time, I left the task of opening the door for our class until the third grade.
I have a belief in my heart-I should do everything seriously and rewrite every word when I write my homework. I remember that I just learned to write in the first grade, and I always can't write well. I cried about it, so I don't believe that I can't write well, so I practice writing every day when I come home from school. Sure enough, I was praised as a "little calligrapher" by my teacher in the conduct comments at the end of grade one, and this good habit persisted until grade five. Because of this good habit, I can get ideal results in every exam.
My schoolbag is always neat. I remember when I was a freshman, I couldn't find anything, and sometimes I couldn't find my homework because my schoolbag was too messy. Then my mother taught me a way to put all kinds of books in one place, big books in one place, small books in one place, stationery in one place and so on. Since my mother taught me this method, I have been sticking to it until now, so I can find anything easily.
I cherish all my things, whether clothes, shoes or books. Once on my ninth birthday, my mother gave me a book "Unsolved Mysteries", which was brand new, but I definitely didn't read it. I love reading, and I have long known the sweetness of "Yan Ruyu in the book". Everything is clean, new and comfortable to look at.
I hope these good habits can accompany me to middle school, university and work …
4. The theme of the composition is "economic assistance, help me grow up", which is about 800 words "economic assistance, help me grow up"
"The sword front comes from sharpening, and the plum blossom fragrance comes from bitter cold." Everyone's birth environment is unchangeable, but everyone's life is built by their own struggle. The family environment is not something we can choose, but we can change it by our own hands. In order to change the embarrassing situation as soon as possible, the state has set up a grant, which provides a guarantee for us to successfully complete our studies.
All men are born unequal, but the country has been trying to make us compete in an environment as fair as possible. State grants are specially set up for students from poor families, which are full of national affection and care. When we just solved the tuition fee, the shortage of living expenses appeared in front of our poor students at an inappropriate time. The shortage of living expenses is a helpless but must be solved problem. Although this is an embarrassing problem that no one wants to face, life cannot be avoided.
In 2008, many things happened in China, such as the Wenchuan earthquake and the world financial crisis. Despite the bad events, the party and the country have not forgotten us, thinking of us all the time, and scholarships have always been around us. We should be honored and proud of such a country.
Let's study hard and strive for progress in the time accompanied by financial aid! We must be worthy of the country, the people and the scholarship that has been with us. Scholarship provides a guarantee for the worry-free life of poor students. Grants are real and become the most needed cotton-padded clothes and lunches for poor students, but they are not only cotton-padded clothes and nutritious lunches, but also the state's mourning and care for poor students. Because others care, they have a reliance in their hearts, and because they care, they are stronger.
In 2009, the world financial crisis was serious, and the state funds were distributed to us again. At this moment, I am very excited. For us poor rural people, it can be said that it is a timely help and gives us comfort. At the same time, it also solves the difficulties in our life and enables us to learn scientific and cultural knowledge and practical technology better.
My family is very poor, and the cost of going to school every year depends entirely on grants. It's a grant from the state, which helps me stick to it and continue my studies. I will never remember this kindness.
Countless irrefutable facts prove that the party and the country will always think of us and scholarships will always accompany us.
Life is cruel, life is unequal, and the road to a better ideal is full of thorns. However, those poor students are no longer afraid and cold-the national bursary lights a lamp for the poor students to struggle in the dark, so that the snowy winter is no longer cold, so that the nutritious lunch is no longer lingering, and the pace towards tomorrow is more vigorous.
Let "funding, help me grow" become the common aspiration of every difficult classmate. Thanks to the party and the country!
5. Grateful for the healthy growth of my egg and milk composition 600 words Since September 2009 1, the "egg and milk project" has been gradually implemented in the compulsory education stage in our district, which has benefited more than 40,000 students.
This is a project that benefits the people and the people; Is an important measure for the party and * * * to care about the health of teenagers; It is a concrete manifestation of the continuous improvement of China's comprehensive national strength and the people's enjoyment of the fruits of reform and opening up in the past 30 years. Every day, when we are still sleeping, teachers get up early to cook eggs and warm milk for us.
When we came to school, the teacher had delivered hot milk and eggs to us. Thinking of this, I can't help but feel a warm current in my heart and deeply feel that the country and teachers have paid too much for us! Every Friday, there will be a special delivery car for eggs and milk, bringing us fresh eggs and Mengniu pure milk.
This fully reflects that the Party and * * * always put the healthy growth of the majority of young people as the top priority. What actions should we take to repay the love of teachers and the concern of the party and * * *? I think everyone is also thinking about this problem! We teenagers are the future of the motherland, and the hope of the future of the motherland is pinned on us! So make sure you have a good body.
With a healthy body, we can study well, master skills and become a useful pillar of the country. Japan once said, "A glass of milk makes a nation strong."
The body is the capital of learning, and you need a strong body to do everything. Isn't a bag of milk and an egg every day the strength of our great Chinese nation? "Egg and Milk Project" is a popular project, love project and nutrition project in happiness project. The implementation of "Egg Milk Project" will certainly improve the nutritional status of primary and secondary school students, further enhance their physique, promote their healthy growth, and effectively reduce the economic burden of primary and secondary school students' families, which fully reflects the care and help of the Party and * * * for children and people.
It makes us realize the care and love of our country, and inspires our patriotism. Let us learn slowly: be grateful to the society and all hard-won things! Care, care, this is the country's concern for the healthy growth of our next generation! We should know how to be grateful for everything the Party and * * * have given us.
6. Composition: Thinking class helps me grow. There are many interesting classes in our school, but what I remember vividly is the thinking class.
It was a hot afternoon, and our class was still excited to welcome the arrival of Espin class. "Ding? ; ? ; ? ; "When the bell rang, Mr. Lu came into the classroom and said," Children, today we are going to hold a little debate contest. The topic of debate is whether Chinese food is better or western food is better. The rule is: 1. You can only add or resist after the students have finished speaking; 2. Keep the classroom quiet. Ok? " "ok!" Our whole class replied loudly, and I thought so: Hehe, of course we support western food, and western food will win, and western food will win! "Ok, let's get started." As soon as the teacher stopped speaking, the students raised their hands. The first student to express his opinion was Shen Yi, who seemed to say, "I think Chinese food is good, because it has more cultural significance, so I think Chinese food is good." "No, western food is good. Because western food is rich in nutrition, Chinese food is easy to lose nutrition when fried and washed. " To Xiao Mu said. The bear said to him again, "Yes! When eating Chinese food, chopsticks are mixed in one plate, which is very unsanitary, but western food is a separate meal system, and each uses its own plate and knife and fork, which is very hygienic. " After a while, Zheng also said to him, "I agree with you very much." In foreign countries, except for sick people, almost everyone's physique is better than ours, and a large part of it is obtained from food. " At this time, Shen Yi seemed to be somewhat dissatisfied and said, "I don't think so. How did our Yao Ming in China and the' world's highest' come out? " China people can cook western food, but for example: Tangyuan, jiaozi, steamed stuffed bun? ; ? ; ? ; ? ; ? ; ? ; Who can do it outside the country? Stop it, even dumplings, jiaozi and steamed buns.
7. Based on the principles of nutrition, health, balanced diet, moderate exercise, physical fitness and breast-nourishing, the dietary guide for athletes in China 1. The food is varied, liquid and low in fat, and 5%-10% is added during training; Reference value of daily vitamin and inorganic salt supply.
A balanced diet can ensure that the energy and various nutrients ingested by the body meet physiological needs, such as vitamins A, E, C and lycopene. In addition, some "ideal values" of biochemical indexes measured to evaluate athletes' dietary nutrition and functional status have been added to the standard, which can be used as a reference for the general population.
This standard gives the recommended reference value of athletes' daily total energy supply (48 sports are divided into 5 grades). People found that; Good morning.
In 2002. In addition, the pros and cons of adding high-quality protein to the diet before exercise should be judged according to the specific situation and individual differences of athletes.
However, people who exercise regularly should try new foods and drinks during training and determine the most suitable eating time for them; 7. Pay attention to rehydration and sugar supplementation; 8。 It has been reported that if the products with high draft exceed the ideal value (range), it is necessary to implement intervention measures such as dietary and sports nutrition supplement, low-fiber food, joint report of athletes, and the Canadian-American Sports Medicine Association (ac ***), so as to ensure the athletes' optimal nutritional status and provide solid material and energy support for high-intensity sports training and competition; To delay fatigue, we should first pay attention to improving the body's ability to resist free radicals, and eat digestible snacks such as cakes and bread before exercise.
In recent years, many studies have proved that maintaining blood sugar level can promote hydration and improve glycogen storage. Studies have shown that eating before exercise has no negative effects and can improve and maintain hemoglobin levels. Sugar should be in moderation and supplemented scientifically afterwards. Appropriate amount of "sugar+protein" electrolyte beverage (the ratio of sugar to protein is 4∶ 1) should be supplemented as soon as possible after exercise, so as to accelerate the elimination of exercise fatigue and the recovery of physical fitness after exercise. Adjust the mood and psychology of athletes.
The study on how to eat before exercise and competition found that eating a meal rich in sugar 2-4 hours before exercise can significantly increase the contents of muscle glycogen and liver glycogen, so that ordinary people and athletes can eat reasonably and supplement nutrition scientifically. Usually, meat should be eaten in moderation.
It is particularly important for athletes to eat sugary food or drinks during the competition if they don't supplement glycogen before the competition, or if they don't eat enough before the competition (such as limiting energy intake in order to lose weight). What to eat can eliminate fatigue as soon as possible. Usually, during and after exercise fatigue, we should take enough nutrients as soon as possible to supplement the energy reserves consumed by the body during exercise and regulate the physiological functions of the body. This is an important measure to relieve exercise fatigue, promote fatigue elimination and restore physical strength.
Therefore; 3. Eat more vegetables, mainly cereals, with balanced nutrition. The disorder caused by the intake of any sugar 1 hour before exercise is temporary, which regulates and improves immune function; Prevent or reduce injuries to bones, joints and soft tissues caused by sports and bananas. For example, for marathon and road cycling athletes, the heat distribution of three meals in the evening and extra meals during training (25% for breakfast, 35%-40% for lunch and no more than 30% for dinner) has no physiological significance. Only one study reported that the intake of sugar 65,438+0 hours before exercise led to the decline of exercise ability. Therefore.
A balanced diet for athletes requires not only a quantitative balance. Eat enough sugar, beans and their products before intensive training; 4. Maintain proper weight and body fat, physical function and training plan.
Their diet should first follow the dietary patterns of China people and dietary guidelines of China residents, and choose different foods according to their sports, different periods and physical functions, and even different seasons and regions. In 2005, China's State Sports General Administration issued the Nutrition Recommendation Standard for Elite Athletes. Although supplementing sugar within 2 hours before exercise will cause a transient increase in plasma insulin concentration, it will not reduce exercise ability. The food selected before exercise should provide 500- 1000kcal of energy, and sugar accounts for 65%-70% of the total energy. Drink milk or yogurt every day; 5; Kg/h sugar (about 30-60g/h), the endurance exercise ability was significantly improved.
So protein 12%- 15%). And take part in long-distance running competitions.
Eat a small amount of sugar such as energy bars, fruit juice (1 ∶ 3 dilution), sugary drinks or fresh fruits (bananas, etc.). Before the competition 1 hour; 2. Balance food intake and exercise. Before 15- 30 minutes, you can take an isotonic sports drink containing sugar and electrolyte.
How to eat food during exercise is the fundamental source of various nutrients, and diet is the natural absorption way of nutrients. In addition to supplementing sugar, American Nutrition Association (ada) can also delay the occurrence of sports fatigue and increase the power output during long-term exercise. Especially, athletes in endurance events should consume sports drinks and fats containing 25%-30% sugar and electrolyte. 6. Pay attention to breakfast and necessary meals. Therefore, in addition to training factors and genetic factors, nutrition is also one of the important factors to win sports.
Reasonable diet and scientific nutrition supplement are also the keys for athletes to win and ensure their physical and mental health, such as 1, 6- fructose diphosphate, alkaline drinks, fruits and potatoes, which athletes take 0.7g/200). Eating them 2-4 hours before moderate-intensity cycling (sugar >:) can promote gastric emptying, reduce intestinal discomfort, and supplement foods containing antioxidants such as vegetables and fruits. A balanced diet must be related to the level of exercise and training, and nutritional supplements should be used reasonably under the guidance of medicine.
It is found that there are still different opinions on whether it is necessary to provide sugar (4%-8%) through sports drinks to improve sports ability for sports lasting less than 1 hour. However, the energy supply ratio of the three major thermal nutrients (sugar 50%-60%.
8. The original meaning of nutrition, health and nutrition is "seeking health", which refers to the process that the human body ingests, digests, absorbs and utilizes the nutrients in food to meet the physiological needs of the body.
[1] Reasonable nutrition refers to providing enough energy and various nutrients for the body through reasonable diet and scientific cooking, and maintaining the balance among various nutrients to meet the normal physiological needs of the human body and maintain healthy nutrition. [1] The significance of rational nutrition lies in promoting growth and development, preventing and treating diseases, enhancing intelligence, promoting prenatal and postnatal care, and enhancing the immune function of the body, so as to achieve the goal of health and longevity.
Nutrients refer to substances in food that can provide energy, body composition, tissue repair and physiological regulation. At present, there are 40-45 kinds of essential nutrients for human body. [2] Among them, protein, lipids, carbohydrates, vitamins, minerals, water and dietary fiber are the most important nutrients for human body.
Two. Health Overview With the development of economy and social progress, people pay more attention to the quality of life and health. The World Health Organization defines health as "health refers to a good state of physical, psychological and social adaptation, not just the absence of disease or physical health".
On this basis, ten standards of health have been formulated: energetic, able to undertake daily life and heavy work calmly without feeling too nervous and tired; Optimistic and positive, willing to take responsibility, no matter big or small, not picky; Be good at rest and sleep well; Strong adaptability, able to adapt to various changes in the external environment; Can resist the common cold and infectious diseases; Proper weight, well-proportioned figure, and coordinated head and shoulder position when standing; Bright eyes, quick response, no inflammation in eyelids; Clean teeth, no dental caries, no pain, normal gum color, no bleeding; Hair shiny, no dandruff; Muscles are plump and skin is elastic. It can be seen that people no longer equate health with no disease, and the concept of health care is more and more widely accepted by people. People maintain a healthy body and a healthy mental state in various ways.
[3] Third, the relationship between nutrition and health. Nutrition is a process in which organisms constantly absorb the necessary substances from the outside to maintain their life activities. Human beings maintain life, ensure growth and development, improve health and complete various activities through nutrition.
Human beings are inseparable from nutrition from fetus to death, and the quality of human physique is closely related to nutritional status. [4] Nutrition is a prerequisite for maintaining human life, a material basis for ensuring physical and mental health, and an important condition for human rehabilitation.
In short, people's birth and death are closely related to nutrition. And those substances needed to maintain the normal growth and metabolism of the body are called "nutrients".
The functions of nutrients mainly include providing energy, promoting growth and tissue repair, and regulating physiological functions. The basic unit that constitutes the human body is the cell, which constitutes the tissue, the tissue constitutes the organ, and the organ constitutes the human body system.
The substances that make up cells come from the nutrients in the food we eat, which are used by the body to nourish the cells in our body. Cell health undoubtedly determines people's health.
At present, there are more than forty kinds of nutrients needed by human body, which can be subdivided into seven categories: first, carbohydrates, whose function is to maintain the activity of body cells, mainly come from grains; Second, lipids, whose function is to maintain cell structure and function, mainly come from oils (edible oil, fat, nuts); Third, protein, whose function is to maintain the activity of body cells, mainly comes from fish, meat, beans, eggs, milk and so on; Fourth, vitamins, whose function is to regulate physiological functions, mainly come from vegetables and fruits; Fifth, minerals, whose function is to establish and repair body tissues and regulate physiological functions, mainly come from vegetables and fruits; Sixth, water, whose function is to regulate physiological functions, mainly comes from drinks and soup; Seventh, dietary fiber, whose function is to prevent gastrointestinal diseases and maintain gastrointestinal health, comes from various plant foods. Reasonable nutrition requires that the percentage of three nutrients in total heat energy is protein 10%~ 15%, fat 20%~30%, and carbohydrate 60%~70%.
Protein is an indispensable substance in human tissues, and it is also the main component of various enzymes, antibodies and some hormones. Fat can supply heat energy, form tissue fat and store fat, supply essential fatty acid (linoleic acid), and fat can also promote the absorption of fat-soluble vitamins.
Carbohydrate is the food source of heat energy, which can save protein and ensure normal blood sugar, liver glycogen and muscle glycogen to maintain brain activity, liver detoxification and muscle activity. Fourth, how to achieve reasonable nutrition? First, the dietary structure should be reasonable and diverse.
China's traditional eating habits are mainly cereals, and he likes to eat miscellaneous grains. The current health concept holds that in the process of cooking, the combination of meat and vegetables should have thickness.
The combination of coarse grains and flour and rice ensures nutrition, and the rice flour in coarse grains can supplement the cellulose needed by human body. Eat more vegetables and fruits with more vitamins, such as radish, celery, Chinese cabbage, bean sprouts, bamboo shoots, oranges, almonds and walnuts. Eat more foods rich in protein, multivitamins and elements such as calcium and iron.
Because vitamin C, antioxidant vitamins and trace elements can soften human blood vessels, remove harmful free radicals and protect myocardium. Eat fish, beef and mutton, milk and bean products properly, which is the source of protein.
The proportion of pork should be appropriate. Eat less salted, fried and smoked foods, and limit the intake of salt, animal oil, fat meat and animal offal.
A healthy human body needs a variety of nutrients, and it is difficult for a single food to satisfy all of them. Only diversification can provide enough protein, vitamins and cellulose, maintain the systematicness of human enzymes, increase resistance and prevent diseases. Secondly, some measures can be taken.
I am a student. As a student, how to achieve reasonable nutrition? Let me talk about some of my ideas: we should carry out active and effective nutrition education among students, hold regular lectures on nutrition knowledge, publish nutrition newspapers and periodicals, offer elective courses on nutrition knowledge, and strengthen publicity and education on nutrition knowledge to improve students' physical quality.
(1) Nutritional knowledge, behavior, attitude and eating habits A The nutritional status of students is closely related to their nutritional knowledge, behavior and attitude. Students eat vegetarian food.
9. How to write an essay I grew up with medicine Friendship is the spice of life and the painkiller of life. It is precisely because of these friends like "condiments" and "painkillers" that my growth path is full of happiness and my life has become colorful.
When I was in kindergarten, I was together every day. We three kids can be said to get along day and night, inseparable, playing together every day, talking and laughing, reluctant to part.
Later, we went to primary school. There are more than 80 students in the class, and I get along well with everyone. We learn from each other and help each other. Although a little naughty, as long as anyone has difficulties, everyone will "draw a sword to help."
Later, XXX transferred to another school, leaving only me and XXX. We used to have problems, but after X left, we decided to get back together. This XXX does some funny actions to make me laugh every day, so we seldom quarrel. XXX has become very lively and brought me endless happiness.
