In the paper Dietary Nutrition and Health, diet is a kind of culture, and China cuisine is world-renowned. It is an indisputable fact that the food in China is delicious and foreigners love it. China's food culture has a long history. The following is my paper on diet, nutrition and health.
Dietary nutrition and health paper 1 1, the concept of food and nutrition.
The definition of "food" in China's Food Safety Law is: food refers to all kinds of finished products and raw materials for human consumption or drinking, as well as articles that are traditionally both food and medicine (but not including articles for therapeutic purposes). Food is the material basis for human survival, and human beings will consume a lot of food in their lifetime, thus ensuring normal life activities such as human metabolism, growth and development. Food can provide energy for human activities, and energy can support the human body to complete life activities. The normal life of human beings can never be separated from food.
Nutrition refers to the total process of human intake and utilization of food, including substances that human intake, digestion, absorption and assimilation. All foods contain certain nutrients. Through special processing, it can be made into foods with rich nutrition, easy digestion and absorption, various types and safe eating. The human body ingests food, digests food and absorbs nutrients in food, thus promoting the growth and development of the human body, resisting aging, defending against viruses, prolonging life and other life processes.
2. The relationship between food and nutrition
Food and nutrition are hot topics that people pay close attention to and play an important role in the national economy and social development of China. The nutritional index of food has also become one of the key research objects in the field of food manufacturing and processing. People's normal life activities are inseparable from food supply. People eat food to solve the problem of "hunger" and absorb basic nutrition from food. At the same time, people pursue "delicious" food to satisfy their own tastes. Now people are eager for "healthy" food. Healthy and nutritious food is not only to ensure human health, but also to better realize its own functional needs for food.
3. The relationship between food nutrition and human health
Protein, fat, carbohydrates, inorganic salts, trace elements, vitamins and water are essential for human body. Food contains nutrients, which are needed by human life and health, human growth and development, and human labor and activities. Human life must be maintained by diet. People's quality of life, mental psychology and diet nutrition are closely related. People's learning ability, resistance to germs, exercise ability, rehabilitation ability, reproductive ability, intelligence, physical strength, height and weight, and life span are all closely related to diet and nutrition. Once the intake of nutrients is unbalanced, it will easily lead to some diseases, thus affecting human life and health. For example, lack of protein will make people panic, lack of fat will make people lazy and unwilling to think, lack of vitamin A will lead to dry skin, and lack of vitamin B 1 will make people get beriberi and other bad symptoms are all related to nutritional imbalance. However, in reality, no food can provide nutrition according to the quantity and the appropriate proportion needed by the human body. Therefore, in order to have a reasonable nutrition and a balanced diet, and to meet the nutritional needs, the human body must ingest a variety of foods, so that the nutrition consumed by the human body is balanced with the nutrition obtained from the food. In a word, human life needs food to maintain, and human health is closely related to food nutrition.
4, food nutrition strengthening measures
The unreasonable dietary structure is the fundamental reason for the imbalance of human nutrition, and the purpose of strengthening food nutrition is to improve human nutrition. By adding vitamins, amino acids and minerals to food, the nutritional index of food can be strengthened. In real life, many people lack nutrition knowledge and blindly pursue the enjoyment of vision and taste when treating food, thus ignoring the nutritional value of food itself. Food should contain as many nutrients as possible to ensure the healthy growth of human body on the basis of meeting the physiological needs of human body. However, in order to seek personal gain and cater to consumers' enjoyment of vision and taste, some food processors ignore the nutritional value standard of food itself, which leads to malnutrition and other symptoms for some people and affects human health.
Nutritional fortification of food is based on the characteristics of human body and the demand of human body for nutrients, and follows the principle of "supplementing what it lacks", adding nutritional fortifiers to food. Generally speaking, nutritional fortifiers are often lacking in food and necessary for human body. Produce special foods with enhanced nutrition for special people and balance their dietary structure. The nutritional strengthening of food must meet the needs of the public. The nutritional fortification of food necessary for people's life plays a significant role in maintaining human health, such as rice, flour, bread, noodles and so on. In China, due to the relatively low economic level of farmers, they can enjoy a limited material base, so there are many malnutrition symptoms among rural residents. Therefore, food nutrition strengthening should be oriented to farmers, and rural areas should be the focus of food nutrition strengthening work. In addition to the staple food for human beings, food nutrition enhancement should also be oriented to human daily necessities, such as cooking oil, salt, vinegar, soy sauce and other condiments. These daily necessities also play an important role in promoting human health. Therefore, adding trace elements such as calcium, iodine, iron and zinc to these daily necessities can also improve their nutritional standards. Besides, people can't live without drinks. Therefore, the strengthening of food nutrition should also be beverage-oriented, especially milk, beverages and other frequently consumed beverages. Adding nutrients to these drinks will help the human body absorb them and play an important role in the nutritional balance of the human body.
Adding nutritional fortifiers to food should not only add nutrients in a targeted way, but also pay attention to food safety to ensure human safety. Use scientific and effective methods to add nutritional fortifiers to ensure that nutrients are not lost. In addition, the government food quality supervision department should strictly supervise food quality, prevent unqualified food from entering the market, and formulate reasonable food nutrition standards.
5. Concluding remarks
Food nutrition is related to people's life and health. Strengthening food nutrition has a positive effect on solving malnutrition symptoms. The human body ingests food and absorbs nutrients in food to meet the needs of normal physiological activities. In daily life, we should pay attention to adjusting the balance of dietary structure to ensure balanced nutrition, thus promoting the healthy development of life.
Diet, nutrition and health for two years-conforming to the honorific title of "four seasons and three days", but people are always influenced by nature.
The yin-yang movement of the universe changes the driving force, thus affecting everything and people.
Therefore, the principle of health care should of course conform to the changes of weather and climate, and four-season health care is the essence of timely health care.
We know how to stay healthy in a day, so how can we stay healthy in a year?
In the health care throughout the year, we should also master three laws: the law of the rise and fall of yin and yang, the law of the rise and fall of qi, and the law of the opening and closing of weather and atmosphere.
After mastering these three laws, we can keep healthy, collect, nourish yin and yang and nourish the five internal organs for a long time.
"Nourishing yang in spring and summer, nourishing yin in autumn and winter" are the two most famous sentences about four seasons health preservation in Huangdi Neijing.
Below, let's learn more about the methods of keeping in good health in the four seasons.
How to raise yang in spring and summer?
In spring, the main hair grows, the air grows, the sun begins to shine, and everything recovers.
Huangdi Neijing tells us that we are "greedy for the sun", that is, we should not hate the sun. At this time, we should lie down at night, get up early in the sun, let us express our liver qi, and let our vitality and vitality run together with the spring qi. This is the so-called four-tone spirit.
Therefore, the focus of spring health preservation is how to coordinate your liver qi and five zang-organs qi with spring qi.
Spring health care is characterized by rising hair and relaxation, so we should pay attention to making the yang in the body prosper gradually.
The climate in spring accelerates people's blood circulation, which is related to the physiological function of the liver. If the liver is abnormal, a series of diseases will occur, so this is the reason why it is appropriate to raise the liver in spring.
In summer, everything is thriving and the sun is shining. At this time, we should make full use of our vitality to safeguard our bodies and our lives.
Summer focuses on nourishing the heart, so we should eat more bitter things, because suffering into the heart is good for our heart and clearing away heat.
Eat more heat-clearing and dampness-promoting things in summer, such as watermelon and mung bean soup.
As for meat, we should eat more cold meat, such as duck, and less warm food like chicken.
Besides, we should try to eat foods that are ripe in summer, such as fruits and vegetables that are ripe in summer.
Eating like this is good for our heart and spleen and stomach.
The last 30 days of summer is the time to nourish the spleen, which is responsible for transportation and transformation. At this time, we need to nourish the spleen, that is, we should cook things before eating.
At this time, the earth will enter a mature stage, the millet is being grouted, and the melons and fruits are almost mature.
This is the best time for us to nourish the spleen and strengthen the spleen.
In summer, when the weather drops, the earth's atmosphere rises, and the atmosphere of heaven and earth intersect, people's mood should be kept happy, so as to make the atmosphere smooth and extroverted.
If you violate this truth, it will hurt your heart.
It is also advisable to sweat a lot in summer. There is a saying that "sweat is the liquid of the heart", so the heart is also the most vulnerable.
Autumn and winter are the time to "enter the ground". We often say that the spring equinox begins to "open the door" and the autumn equinox begins to "enter the ground".
When we enter the house, we have to collect everything, and we also have to raise it.
After spring and summer, heaven and earth seem tired.
Everything that should have grown has matured, and fruits and crops have been harvested. At this time, people should also turn to rest, which is called "harvesting".
The most important thing in autumn is to nourish the lungs.
After the summer heat, the lungs are dry. At this time, we should eat more nourishing things, such as pears, lotus roots, almonds, Fritillaria and lilies, to nourish our lungs, moisten our lungs and inhibit our lung qi.
The humidity drops in autumn, which is a season easy to catch a cold.
The weather in autumn is dry, and "dryness" is easy to hurt the lungs and affect the function of Qi-flowing.
Thereby causing dry cough and less phlegm.
Therefore, it is the theoretical basis of nourishing the lungs in autumn to "clear the lungs without ambition".
After winter, the Lord hid.
At this time, everything was closed, the animals went to hibernate, the flowers withered and the leaves fell out. Then people, their bodies should rest.
The most important health care in winter is to raise and hide. What are you hiding?
If you hide sperm, you won't get sick in the coming year, so you say, "If you don't hide sperm in winter, you will get sick in spring."
Once a patient came to see me. He always catches a cold, while I always catch a cold in spring.
I said what did you do in winter, and he said he was on a business trip this winter, so tired.
In fact, this is the result that he didn't hide his essence in winter.
I told him to make up for it now, to have a "I am in a happy mood when I wake up this morning in spring" as soon as possible, and to keep my spirit through sleep.
Among the solar terms with abnormal weather and climate, it is most important to pay attention to the changes of Yin and Yang throughout the year, which is the basis for the birth, growth, culture, harvest and storage of all things. Therefore, it is necessary to raise yang in spring and summer and yin in autumn and winter.
The alternation of cold and summer in four seasons will cause people's physical and psychological discomfort, so it is very necessary for us to follow the changes of the 24 solar terms for health care.
Twenty-four solar terms have a very long history in China. It is not only a compass for agricultural production, but also a secret treasure to guide people's health care.
Everyone is familiar with the 24 solar terms. There are six solar terms in a season and twenty-four solar terms in a year.
"Spring rain surprises spring and clear valley days, summer is full and summer is hot, autumn dew and frost, winter snow and snow." This is Four Seasons solar term song.
Of the 24 solar terms, eight are very important. Among the twenty-four solar terms, the focus is on these eight solar terms: the second solstice, that is, the summer solstice and the winter solstice; Dichotomy, namely vernal equinox and autumnal equinox; Beginning of spring, Changchun, beginning of autumn and beginning of winter.
Therefore, we should choose these eight solar terms because they represent the most representative climate change in the four seasons.
When these solar terms come, the climate will change, cold will be cold, hot will be hot, rain will rain, wind will wind; Spring breeze is blowing, summer wind is blowing, and winter wind is blowing.
If our bodies adapt to the changes of the four seasons, just as spring is a warm climate, summer is a hot climate, winter is a cold climate, and you are cool in autumn, then people are not easy to get sick.
On the other hand, if spring is a recoil wind, or a hedge wind, just like Xia Feng in winter, it should be cold and hot, while summer is a winter wind, it should be hot and cold. When such a climate change occurs, you should pay attention to health preservation, because this untimely climate is the most prone to diseases.
The weather is hot and cold, your body is hot and cold, and the exhaustion of your body and the abnormal weather are easy to get sick. Pay attention to maintenance at this time.
The Book of Changes tells us that people's qi is endowed by heaven and earth, so people's health should be based on the yin of heaven and earth and the changes of Yang Qi.
This philosophy of health preservation can be simply summarized in one sentence: conforming to nature leads to the success of health preservation, while violating nature leads to many diseases.
They are all in the Five Elements-five lines of gossip, Eight Diagrams and Five Elements. Each of them has its own corresponding body parts and acupoints.
We use the image of gossip to discuss human physique, in fact, we are predicting human physique and health.
Its value is also reflected in: through understanding the application, learn to self-adjust, and really take the initiative of health and longevity in your own hands.
