General Principle: Increase the intake of total energy

Eat: eat rice, noodles and other carbohydrate-containing foods, supplement meat and other high-quality protein

Drink water: it is appropriate to use a few times

Urban construction has developed rapidly over the years. Guangzhou has a large number of construction workers working at construction sites. They are building blocks for the city. The daily labor intensity is very large. Occasionally, it needs to be operated in high temperature and dust environment and may even be exposed to some harmful chemical substances. Under such circumstances, how to properly diet can "full blood resurrection" while preventing the potential threat of occupational diseases?

Recently, the fourth session of the Food Safety Auditorium jointly organized by the Guangzhou Food and Drug Administration and Guangzhou Daily, the Guangzhou Nansha District Food Safety Committee Office, and the CCCC Nansha General Contracting Department co-organized the Pearl of Phoenix Bridge in Nansha District. Bay Center Plaza opened. The lecture invited Professor Liu Yi, the chief physician of the Twelfth People’s Hospital of Guangzhou City, to give lectures on prevention and control of occupational diseases for construction workers.

High-intensity operations consume most carbohydrates

Construction workers work hard and take a long time. Liu immigration analysis said that high-intensity operations have a large total energy expenditure on the body, increased muscle glycogen consumption, increased protein breakdown, increased oxygen consumption, and increased sweating.

How to properly supplement energy after high-intensity labor to achieve "full blood resurrection"?

"Increase in total energy intake is very important." Liu immigrants said that after the daily high-intensity work, increase the intake of carbohydrates such as rice, noodles, and bread, and supplement high-quality protein such as meat and eggs during labor hours. In the case of long and sweating, it is necessary to replenish water and electrolytes in a timely manner.

High temperature and sweaty drinking water a few times more reasonable

The construction site is a relatively high temperature place in the city. Especially in the summer, sweating has become a true portrayal of workers. When working in a high-temperature environment, workers are prone to rapid heart rate, excessive sweating, and increased metabolism. Liu immigration reminded that this can easily lead to loss of body water and electrolytes, loss of water-soluble vitamins, reduced heat capacity, and decreased digestive juices, digestive dysfunction, resulting in decreased appetite.

How to reasonably replenish water after high temperature operation?

"It should be a small number of times is appropriate, so as not to affect appetite." Liu immigrants suggest that the temperature of supplemental beverages is appropriate to about 10 °C. In addition, various soups such as fish soup, vegetable soup and broth can be eaten in alternation.

Anti-dust

Work under the dust easily hurt lung diet should avoid heat stimulation

"Different sizes and types of dust can cause different symptoms in the lungs." Liu Yi said, long-awaited in a dust environment, easily lead to cough, sputum, pulmonary ventilation dysfunction, and even suffering from bronchitis, lung Department of infection, long-term non-intervention, serious and even the development of lung cancer and other diseases.

He suggested that operators operating in a dusty environment should usually avoid dust as much as possible, enhance immunity, and eat less irritating foods to help protect the health of the lungs.

Avoid dust: insist on wearing a mask that meets the regulations and reduce dust exposure.

Strong immunity: Eat more milk, lean meat, eggs and soy products and other foods rich in high quality protein; eat more pears, oranges and other fruits with heat, thirst and phlegm; choose vitamins and minerals rich Fresh fruits and vegetables, such as tomatoes, melon, green bean sprouts, watermelons, pineapples and so on.

Avoid irritation: When you have upper respiratory tract infection or lung infection, do not eat or eat hard and high-fiber foods; fast or eat spicy foods such as pepper, green onion, onion, strong tea, coffee, etc., so as not to aggravate cough and asthma. Other symptoms; avoid eating greasy food and wine.

Anti-heavy metal

Adequate intake of Vitamin minerals to reduce chemical damage

In the construction environment, there may be toxic heavy metals such as lead, mercury, cadmium, and organic dichloroethane. When they enter the human body, they damage the metabolism of nutrients in the body, or damage specific target organs, and endanger the human body in varying degrees. Working in this environment, how to increase their immunity, promote the body's detoxification and detoxification?

Immigration Liu suggested that workers exposed to lead and mercury can increase the intake of high-quality proteins such as milk, eggs, beef, scallops, and soy products, and at the same time appropriately limit dietary fat intake because high-fat diets can cause poisons in the small intestine. The absorption in the increase.

In addition, it is also important to ingest adequate vitamins and minerals. He suggested that workers exposed to lead and mercury, in addition to daily intake of 500g vegetables, should also be supplemented with 100mg of vitamin C, and vitamin B1, B12 and folic acid, etc., in order to promote the synthesis of hemoglobin and red blood cell production, reduce lead, etc. Hematopoietic system damage. In addition, adherence to dietary diversification ensures adequate intake of minerals such as calcium, iron, zinc and selenium, as well as resistance to the absorption of toxic metals and the promotion of discharge.

Beware of two common food poisonings

According to Liu's immigrants, food poisoning is mainly divided into chemical food poisoning and bacterial food poisoning. For example, melamine, clenbuterol, nitrite, arsenide, organophosphorus pesticides are chemical poisoning. Infections such as Staphylococcus aureus and Clostridium botulinum are bacterial poisoning. He separately interprets and deals with the characteristics and prevention of these two common types of food poisoning:

First, anti-chemical food poisoning

Common nitrite poisoning, mainly due to intake of long-lived raw and cooked vegetables, fresh vegetables just before pickling, salt added to the excessive amount of nitrite, mistakenly nitrite as salt and so on. The incubation period for this kind of poisoning is usually 1 to 3 hours, and individual even up to 20 hours. Poisoning can occur lips, tongue, nails and body skin purpura, accompanied by dizziness, headache, rapid heart rate, irritability or lethargy, gastrointestinal symptoms, severe cases can be coma, convulsions, such as the occurrence of respiratory and circulatory failure and death.

In terms of prevention, Liu Immigration gave 4 tips:

1. Keep vegetables fresh during daily eating. Do not eat decayed vegetables. Leftovers must not be stored for too long.

2. The salt content of pickles should be >20%, and pickle must be eaten after 15 days.

3. According to the national health standard, salted nitrite should be <20mg/kg.

4. Do not drink bitter well water, do not use bitter water to cook rice, porridge, in particular, can not spend the night.

Second, antibacterial food poisoning

Immigration from Liu pointed out that the symptoms of poisoning caused by different bacteria are different. For example, Staphylococcus aureus poisoning can cause severe nausea, vomiting, diarrhea, abdominal pain, Clostridium botulinum poisoning can cause loss of sound, blurred vision, drooping eyelids, difficulty swallowing, Difficult breathing and so on. Once the above symptoms occur, you should seek medical advice as soon as possible.

How to prevent bacterial food poisoning? Immigrant Liu also gave three reminders:

1. To prevent the intake of contaminated food: Do not eat dead animals and meat; Food production, storage and transportation, sales process to prevent flies, rodents, dust, anti-fouling; raw and cooked meat during cooking to be treated separately, Sheng food The container should be sterilized.

2. Food should be properly stored: The key to controlling the growth and reproduction of microorganisms in food lies in the environment in which it is stored. For example, animal foods should generally be kept at a low temperature and stored at low temperatures (below 5°C in the dark); cooked foods should not be stored for too long.

3. Thoroughly pasteurize before eating: When the food is heated to 100°C, it can kill the common pathogenic bacteria for more than 5 minutes, but the spores should be eliminated. The heating time needs to be longer; in addition, do not eat raw sauce; Eat thoroughly, must be thoroughly heated before eating; eggs must be boiled for more than 8 minutes before consumption.

Plant Extract

Plant extracts refer to a class of substances derived from plants that have one or more biological functions. Can be separated by physical and chemical extraction of one or more effective components formed by natural products.
There are many kinds of plant extracts. At present, natural plant extracts mainly include essential oils, saponins, alkaloids, polysaccharides, polyphenols, flavonoids and so on. According to the biological activity, it can be divided into antioxidants: grape seed extract, green tea extract, pine bark extract, etc. Immune modulators: ginseng extract, gynostemma pentaphyllum extract, Ganoderma lucidum extract, etc. Improve cardiovascular function: ginkgo biloba extract, lotus seed heart extract, rhodiola extract, etc. Sedative: valerian extract, hop extract and so on.
According to their own characteristics in the market application of plant extracts can be roughly divided into six categories: coloring, seasoning, medicinal, health, dietary supplements and feed additives. Natural plant pigments refer to pigment components in roots, stems, leaves, flowers, fruits and bark of plants, such as turmeric, sappanwood, indigo, safflower, black bean and green walnut peel. Natural plant pigments are widely used in food, textiles, cosmetics, medicine, leather industry, printing and dyeing and other industries.
Plant extracts are rich in ingredients that can effectively stimulate the senses, such as sweeteners and volatile substances. Natural sweeteners, such as stevia glycoside and grosvenin, are popular new sweeteners. They are not only sweet, but also ideal substitutes for sucrose. Essential oils are concentrated volatile substances that are commonly used in the preparation of fragrances and are widely recognized in plant extracts.
Contained in the plant extracts of saponins, alkaloids, polyphenols, flavonoids and other ingredients are widely study has many biological activities, such as antioxidant, antibacterial, anti-inflammatory, improve animal production performance, antivirus, enhance immunity, etc., for human and animal health has the effect of nots allow to ignore, and the development of its pharmacology and health care function has become the main trend of plant extracts.In addition, as a dietary supplement, it is one of the main applications of various plant extracts. Such as oligosaccharides (oligosaccharides, oligosaccharides, oligosaccharides, galactose, etc.) dietary fiber, soybean protein, dietary fiber, wheat albumin, L-arabinose, sugar alcohol (xylitol, malt heavy sugar alcohol, sorbitol, etc.) and other natural plant food additives have been widely used in the food health care market. Many plant functional ingredients with anti-inflammatory, antioxidant and bacteriostatic properties are also commonly used as substitute anti-bacterial products. The application of green feed additives in livestock and poultry production has been vigorously developed, such as green tea polyphenols extract, pine bark procyanidins extract and polyanthocyanidins extract.
Due to the changes in lifestyle, working mode and consumption mode, more consumers are pursuing the life concept of "big health". The so-called "big health" refers to a concept of whole-process, comprehensive and total factor care for people's life around the basic necessities of life, life, old age, illness and death. It not only pursues individual physical and physical health, but also pursues mental, spiritual, social, environmental and family health. In the era of "great health", natural plant-based health products are the core and the key material basis.
With increasing attention to the food and drug safety, from natural plant in the development and utilization of the active ingredient is becoming more and more attention, a large number of food safety, have certain curative effect function of plant extracts have been used as raw materials in a variety of ways into functional food nutrition and health food has entered people's lives, and will play a more and more important role.
And more and more new research new discovery, predicts that the plant extract industry chain will have more members to join, there will be more business opportunities. The future domestic plant extract market will stride forward gradually to mature period!
