Diet Nutrition and Health, diet is a kind of culture, and China cuisine is world-renowned. It is an indisputable fact that China's food 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 excluding 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 the necessary energy for human activities, and energy supports 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. After special processing, it can be made into food with rich nutrition, easy digestion and absorption, diverse varieties and safe eating. The human body ingests food, digests food, and absorbs nutrients in food, thus promoting human growth and development, anti-aging, virus defense, longevity 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 their 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 necessary for 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 nutrient intake is unbalanced, it will easily lead to some diseases and affect human life and health. For example, the lack of protein will make people panic, the lack of fat will make people lazy and unwilling to think, the lack of vitamin A will lead to dry skin, and the lack of vitamin B 1 will make people get beriberi and other adverse symptoms, all of which are related to the imbalance of nutrients. But in reality, no food can provide nutrition according to the amount needed by the human body and the desired appropriate proportion. Therefore, in order to have a reasonable nutrition and a balanced diet, and to meet the needs of nutrition, the human body must ingest a variety of foods, so that the nutrition ingested by the human body can be balanced with the nutrition obtained from food. In a word, human life needs food to maintain, and human health is closely related to food nutrition.
4, food nutrition strengthening measures
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 in 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 in 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. Nutritional fortification of foods necessary for people's lives, such as rice, flour, bread, noodles, etc., plays a significant role in maintaining human health. In China, due to the relatively low economic level of farmers and the limited material base they can enjoy, 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 human staple food, 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. In addition, people can't live without drinks. Therefore, the strengthening of food nutrition should also be beverage-oriented, especially milk, beverages and other drinks that are often drunk. Adding nutrients to these drinks is helpful to human absorption and plays an important role in human nutritional balance.
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. Scientific and effective methods are used to add nutritional fortifiers to ensure that nutrients are not lost. In addition, government food quality supervision departments 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, ensuring balanced nutrition and promoting the healthy development of life.
Dietary nutrition and health for two years-following the four seasons and three laws, people are honored as the spirit of all things, 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 change of weather and climate, and health care in four seasons 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?
Three laws should also be mastered in the health care throughout the year: 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.
Mastering these three laws, you can preserve health, 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?
Spring comes, the air grows, the sun begins to shine, and everything recovers.
Huangdi Neijing tells us that "greedy for the sun" means not to hate the sun. At this time, we should lie down at night and get up early to bask in the sun, so that our liver qi can be vented and our vitality and vigor can run with the spring qi. It's called "Four Temperaments".
Therefore, the key point of keeping in good health in spring is how to coordinate your liver qi and the qi of your internal organs with spring qi.
Spring health care is characterized by rising hair and relaxing, and attention should be paid to making the yang in the body gradually flourish.
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 from the heart is good for us to clear the heart and reduce the fire, and clear away heat.
Eat more heat-clearing and dampness-promoting things in summer, such as watermelon and mung bean soup.
As for meat, eat more cold meat, such as duck, and eat less warm things like chicken.
In addition, 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, it is necessary to replenish the spleen, that is, to cook things before eating.
And at this time, the earth will enter a mature stage, the millet is being grouted, and the melons and fruits are almost ripe.
This time is the best time for us to replenish the spleen and strengthen the spleen.
In summer, the weather drops, the atmosphere rises, the atmosphere of heaven and earth intersect, and people's mood should be kept happy, so that the atmosphere can be smooth and outgoing.
If you violate this truth, it will break your heart.
It is also advisable to sweat a lot in summer, and there is a saying that "sweat is the liquid of the heart", so the heart is also the most fragile.
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 accept everything, and we have to raise it.
After spring and summer, the world seems to be tired.
Everything that should grow is ripe, and all the fruits and crops are harvested. At this time, people should also turn to rest, which is called "harvesting".
Autumn is mainly about nourishing the lungs.
After the heat, the lungs are dry. At this time, we should eat more nourishing things, such as pears, lotus roots, almonds, Fritillaria, lilies, etc., to nourish and moisten the lungs and restrain 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 propaganda.
Thereby causing dry cough and less phlegm.
Therefore, it is the theoretical basis of nourishing the lungs in autumn that "the chest is not ambitious but the lungs are clear".
After the winter, God 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 will not 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, and I always catch a cold in spring.
I said what did you do in winter, and he said that 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, as soon as possible to have a "I woke up this morning in spring with a relaxed mood", and to maintain the essence 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 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 and carry out 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 is cold and frost, and winter snow is drifting." This is Four Seasons solar term song.
Of the 24 solar terms, eight are very important. Among the 24 solar terms we are talking about, 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, 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 changes, the cold is cold, the hot is hot, the rain is rainy, and the wind is windy; Spring breeze blows, summer breeze blows, winter breeze blows.
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, spring is a recoil wind, or a hedge wind, just like Xia Feng in winter, it should be hot and cold, and summer is a winter wind, it should be hot and cold. When there is such a climate change, you should pay attention to health, because this unseasonable climate is the time when diseases are most likely to occur.
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 given by heaven and earth, so people's health preservation should be carried out according to the changes of Yin and Yang of heaven and earth and Yang Qi.
This philosophy of health preservation can be simply summarized as one sentence: conforming to nature leads to success in health preservation, and violating nature leads to illness.
They are all in the Five Elements-five lines of gossip and Eight Diagrams, and the secret of keeping in good health has its 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 cognitive application, learn to self-adjust, and really take the initiative of health and longevity in your own hands.
