Dietary nutrition and health paper

Dietary nutrition and health paper, diet is a kind of culture, while Chinese cuisine is famous all over the world. 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 1

1. 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 the normal life activities such as human metabolism, growth and development. Food can supply 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 food intake and utilization by human body, including substances that human body is ingesting, digesting, absorbing and assimilating. All foods contain certain nutrients. By special processing, foods rich in nutrients, easy to digest and absorb, various and safe to eat can be made. 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 of concern to the general public today, and they play an important role in China's national economic and social development. 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 can't be separated from food supply. People ingest food to solve the problem of "hungry" and absorb basic nutrients from food. At the same time, people pursue "delicious" food and satisfy their taste. 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. Relationship between food nutrition and human health

The human body needs protein, fat, carbohydrates, inorganic salts, trace elements, vitamins and water. Food contains nutrients, which are needed for human life and health, for human growth and development, and for human labor and activities. People's life must be maintained by diet. People's quality of life, mental psychology and diet nutrition are closely related. People's learning ability, ability to resist germs, exercise ability, rehabilitation ability, reproductive ability, intelligence, physical strength, height and weight, and life span are closely related to diet nutrition. Once the intake of nutrients is unbalanced, it will easily lead to some diseases, which will 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 B1 will make people get beriberi and other adverse symptoms related to the imbalance of nutrients. However, in reality, no food can provide nutrients according to the quantity needed by the human body and the desired suitable ratio. Therefore, in order to have a reasonable nutrition and a balanced diet, in order to meet the needs of nutrition, the human body must consume a variety of foods, so that the nutrition consumed by the human body can be balanced with the nutrition obtained from the food. In short, human life needs food to maintain, and human health is closely related to food nutrition.

4. Measures to strengthen food nutrition

Unreasonable dietary structure is the fundamental reason for the imbalance of human nutrition, and the purpose of food nutrition strengthening is to improve the nutritional status of human beings. By adding vitamins, amino acids and minerals to food, the nutritional index of food can be strengthened. In real life, many people are short of 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 human physiological needs. However, in order to seek self-interest and cater to the enjoyment of vision and taste of consumers, 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 to add nutritional fortifiers to food according to the characteristics of human body and the demand for nutrients. Generally speaking, nutritional fortifiers are often lacking in food and necessary for human body. Produce special foods with fortified nutrition for special people and balance their dietary structure. Nutritional fortification of food must meet the needs of the public. Nutritional fortification of foods necessary for people's lives has a significant effect on maintaining human health, such as rice, flour, bread, noodles and so on. In our country, 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 regarded as 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 edible 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, food nutrition strengthening should also be oriented to drinks, especially milk, drinks and other drinks that are often drunk. Adding nutrients to these drinks will help the human body absorb and play an important role in the nutritional balance of the human body.

when adding nutritional fortifiers to food, we 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, the government food quality supervision department should strictly supervise the food quality, put an end to the substandard food in the market, and formulate reasonable food nutrition standards.

5. Conclusion

Food nutrition is related to human life and health, and strengthening food nutrition plays a positive role in solving malnutrition symptoms. The human body ingests food, absorbs nutrients in food, and ensures the needs of normal physiological activities of the human body. In daily life, we should pay attention to adjusting the balance of dietary structure and ensuring the nutritional balance, so as to promote the healthy development of life.

annual health preservation-conforming to the three laws of the four seasons, people have the honor of being the spirit of everything, but people are also influenced by nature all the time.

The movement of Yin and Yang in the universe makes the driver change, which affects everything and people.

therefore, the principle of keeping in good health should of course conform to the change of weather and climate, and keeping in good health in four seasons is the essence of keeping in good health in time.

We know how to keep in good health in a day, so how do we keep in good health in a year?

We should also master three laws for keeping in good health all year round: the law of the ebb and flow of Yin and Yang, the law of the rise and fall of Qi, and the law of the opening and closing of weather.

after mastering these three laws, we can preserve our health for a long time, enrich our collection, nourish Yin and Yang, and nourish our five internal organs.

"Nourishing yang in spring and summer, nourishing yin in autumn and winter" are the two most famous sentences in Huangdi Neijing about keeping healthy in four seasons.

below, let's learn about the methods of keeping in good health in four seasons.

how to raise yang in spring and summer?

in spring, the hair grows, the air grows and the sun begins to shine, and everything recovers.

Huangdi Neijing tells us that we are "insatiable on the sun", that is, we should not hate the sun. At this time, we should lie down at night and get up early to bask in the sun, let us express our liver qi, and let our vitality and qi flow with the spring qi. This is called four qi regulating the spirit.

Therefore, the key point of spring health preservation is how to coordinate your liver qi, five zang-organs qi and spring qi.

spring health preservation is characterized by rising hair and relaxing, so we should pay attention to make 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 appear, so this is the reason why the liver should be nourished in spring.

In summer, everything is flourishing and the yang is strong. At this time, we should make full use of our vitality to maintain our bodies and our lives.

In summer, it is important to nourish the heart, so we should eat more bitter things, because suffering into the heart is good for clearing our heart fire and clearing our heat.

In summer, we should eat more things to clear away heat and promote dampness, such as watermelon and mung bean soup.

As for meat, we should eat more cold and cold meat, such as duck meat, and eat less warm things like chicken.

In addition, 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 31 days of summer is the time to nourish the spleen, which governs the transport and transformation. At this time, we need to nourish the spleen, that is, we should 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 nourish the spleen and strengthen the spleen.

In summer, when the weather drops, the atmosphere of the earth rises, and the atmosphere of heaven and earth intersects, people's mood should be kept happy, so that the qi can be smooth and outgoing.

if you violate this truth, you will be heartbroken.

In summer, it is advisable to sweat a lot, and there is a saying that "sweat is the liquid of the heart", so the heart is also the most easily damaged.

autumn and winter are the time to enter the earth. We often say that the vernal equinox begins to "open the heaven" and the autumnal equinox begins to "enter the earth".

when entering the land, everything should be collected, and our human body should also raise it.

after spring and summer, the world seems to be tired.

Everything is ripe, and fruits and crops are collected. At this time, people should also turn to rest, which is called "harvesting".

in autumn, we should mainly raise lungs.

The lungs are dry after the summer heat. At this time, we should eat more moist things, such as pears, lotus roots, almonds, Fritillaria and lilies, to nourish our lungs, moisten our lungs and restrain our lung qi.

The humidity drops in autumn, which is the season of catching cold easily.

In autumn, the weather is dry, and "dryness" is easy to hurt the lungs, which affects the function of qi propaganda.

thus causing symptoms such as dry cough and less phlegm.

Therefore, it is the theoretical basis of nourishing the lungs in autumn to "clear the lungs".

after winter, the Lord hides.

At this time, everything is closed, animals have gone to hibernate, flowers have withered, and leaves have fallen out. Then people should have a rest.

The most important health preservation in winter is to keep hidden. What should you hide?

If you keep the essence well, you won't get sick next year, so it is said that "if you don't keep the essence in winter, you will get sick in spring".

once a patient came to see me. He always caught a cold, and I kept catching a cold in spring.

I said what did you do in winter, and he said that he had been on a business trip this winter, and he was so tired.

In fact, this is the result that he didn't hide essence to nourish his body in winter.

I told him to make up for it now, and to have a "I awake light-hearted this morning of spring" as soon as possible to maintain his essence through sleep.

The solar terms with abnormal weather need to pay attention to the change of Yin and Yang throughout the year, which is the foundation of everything's birth, growth, transformation, harvest and storage. Therefore, it is necessary to nourish 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 change of 24 solar terms and carry out health care.

24 solar terms has 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 twenty-four solar terms. There are six solar terms in a season, and a year is twenty-four.

"Spring rains shock the spring and clear the valley, summer is full and summer is hot, autumn is exposed with cold and frost, and winter is snowy and snowy." This is solar term song in four seasons.

Among the 24 solar terms, eight solar terms are very important. In 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, long summer, beginning of autumn and beginning of winter.

Therefore, these eight solar terms are chosen because they represent the most representative climate change in the four seasons.

when these solar terms come, the climate will change. When it is cold, it will be cold, when it is hot, it will rain, and when it is windy, it will be windy. Spring breeze blows, summer breeze blows, and winter breeze blows.

If our bodies adapt to the changes of the four seasons, just like spring is a warm climate, summer is a hot climate, winter is a cold climate, and you are cool in autumn, people are not easy to get sick.

On the other hand, if the spring is a recoil wind, or a hedge wind, just like the summer wind in winter, it should be cold and hot, and the winter wind in summer should be hot and cold. When there is such a climate change, you should pay attention to health, because this unseasonably seasonal climate is the time when diseases are most likely to occur.

The weather is hot or cold, and your body is cold or hot. If your body is weak or not, and the weather is abnormal, you are prone to get sick, so you should 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 care should be carried out according to the changes of yin and yang qi of heaven and earth.

This philosophy of keeping in good health can be simply summed up in one sentence: conforming to nature leads to success in keeping in good health, while violating nature leads to many diseases.

They are all in the Five Elements-five lines of gossip and the Eight Diagrams and Five Elements, the secrets of physical health preservation, each have its own corresponding body parts and acupoints.

We use the image of gossip to explore human physique, in fact, we are predicting the physical quality and health status of the human body.

its value also lies in: by recognizing the application, learning to adjust oneself, and truly taking the initiative of health and longevity into your own hands. Dietary Nutrition and Health Paper 3
