Introduction: Health is the normal state of human life and is the key to economic development, social progress and national prosperity. guarantee. Our country's Constitution clearly stipulates: Maintaining the health of all citizens and improving the health level of people of all ethnic groups is one of the important tasks of socialist construction. Helping people get healthy is the responsibility of each of our health workers, and it is also the sacred mission of every health educator.

(1) What is health?

Due to the different times, environments and conditions in which people live, their understanding of health is also different. In the past, people generally believed that a body without disease, injury, or disability was "healthy." With the changes in the spectrum of human diseases and the transformation of medical models, people's understanding of health is also deepening. Modern people realize that in addition to biological factors, psychological and social factors as well as bad living habits, lifestyles, and behaviors are important causes of many diseases and deaths. When paying attention to human health, it is obviously not comprehensive enough to look at the problem from the perspective of "biohuman" alone. The impact of social factors and psychological factors on human health must be taken into consideration. As this understanding deepens, the past "biomedical model" is transformed into a "biological, psychological, and social" medical model.

The World Health Organization (WHO) stated in its Constitution in 1948: "Health is not only the absence of disease or weakness, but a perfect state of physical, mental health and social well-being." That is to say, human health is not only the absence of physical disease, soundness and weakness, but also a state of psychological and spiritual balance, and also includes good adaptation between people and society, and the achievement of harmonious coexistence with society. Man not only has a body but also a spirit; man is not only a natural person, a biological person, but also a social person. This new concept of health is a comprehensive definition of health that combines the human body with the spirit and the individual with society.

A completely healthy person is not only objectively healthy, but also should understand basic health knowledge, have the belief and awareness to pursue health, have a healthy lifestyle, and at the same time bear health responsibilities to others and society. .

There is also a state between health and disease, which we call sub-health. It often refers to the absence of clinical symptoms and signs, or the feeling of illness without clinical evidence, but there is information about potential disease tendencies, and it is in a state of low quality and psychological imbalance of body structure degradation and physiological function decline.

(2) Factors affecting health

Human health is affected by many factors. In addition to intrinsic factors such as genetics, psychology and behavior (lifestyle), the biological environment, society External factors such as the environment and natural environment are closely related to human health.

Social environment: Social environment factors include political system, social stability (war or peace), economic status, medical and health services, food and drinking water supply, community services, interpersonal relationships, cultural customs, etc., among which All are closely related to health.

Natural environment: It includes climate conditions, geographical conditions, water quality and soil conditions (including minerals), magnetic fields and rays, etc., which are also directly related to human survival and health. For example, in some areas, endemic diseases such as fluorosis, iodine deficiency disease, Kashin-Beck disease, and Keshan disease can occur due to too much or too little trace elements in water and soil.

Biological environment: mainly refers to the biological state of the environment in which people live, especially the concentration, activity and pathogenicity of organisms that cause and spread diseases. Such as viruses, bacteria and other microorganisms, mosquitoes, flies, cockroaches and other insect vectors, and mice and other animals. When the concentration of these organisms in the environment in which humans live is high or they are highly pathogenic, they will inevitably pose a threat to human health.

Genetic factors: A person’s physical characteristics will be passed on to offspring, and certain diseases are also hereditary, such as hemophilia, albinism, diabetes, etc.

Psychological factors: It can directly or indirectly affect health. For example, long-term psychological stress can cause high blood pressure, and sudden emotional excitement can cause cardiovascular and cerebrovascular diseases.

Behavioral (lifestyle) factors: Unhealthy lifestyles can also directly or indirectly harm health. For example, long-term heavy smoking can lead to tracheitis, hypertension and other diseases, and even increase the risk of lung cancer and other diseases. Chances of cancer. Excessive drinking over a long period of time can damage the liver and cause other digestive problems. A high-fat and high-cholesterol diet can lead to arteriosclerosis and coronary heart disease. A high-sugar diet and lack of exercise may cause diabetes.

Scientific research shows that among the above-mentioned factors that affect health, 45% of the diseases suffered by humans are related to lifestyle, and 60% of the death factors are related to lifestyle. In the United States, unhealthy lifestyle accounts for 48.9 of the total causes of death, and in our country it accounts for 37.3. This shows that human behavioral factors have a great impact on their own health.

A person’s lifestyle is largely influenced by his family in the early stages, such as eating habits, hygiene habits (such as toothbrushing habits), and daily living habits. However, as age increases, people will gradually adjust their behavior due to the influence of the surrounding environment, and will form relatively fixed behavioral habits after entering youth and adulthood. Such as whether you pay attention to hygiene, whether you like sports, whether you like to communicate with others, whether you smoke and drink, etc. These behavioral habits, that is, lifestyle, will have a long-term impact on their health.

In 1992, the World Health Organization proposed four cornerstones of a healthy lifestyle: reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance. If this could be done, the life expectancy of the global population could be extended by more than 10 years.

1. Reasonable diet. That is, nutrition should be comprehensive and balanced. It is advisable to be 80% full for each meal. The staple food should be a combination of fine grains and miscellaneous grains. Reduce the intake of animal fats and sweets. Eat more fresh vegetables, fruits, soy products and milk. Limit the amount of salt. The daily salt intake per person of no more than 6 grams.

2. Exercise moderately. The most important thing about exercise is persistence and moderation. The program should vary from person to person. You can do mild to moderate exercise 5 times a week, for about half an hour each time. Young and middle-aged people can play ball and long-distance running. Middle-aged and elderly people can walk briskly, jog, and ride bicycles. Moderate exercise is an important factor in preventing and eliminating fatigue and ensuring health and longevity.

3. Quit smoking and limit alcohol consumption. Smoking and drinking are the enemies of health. Smoking is an important harmful factor leading to many diseases such as hypertension, coronary heart disease, lung cancer, bronchitis, and emphysema. People of any age can reap real health benefits by quitting smoking. Scientists have discovered after years of experiments that smokers’ internal organs will undergo a series of beneficial changes after quitting smoking: Within 20 minutes: blood pressure drops to standard levels; pulse drops to standard speed; the temperature of hands and feet rises to standard body temperature .

Within 8 hours: the carbon monoxide content in the blood decreases to normal levels; the oxygen content in the blood increases to normal levels. Within 24 hours: The risk of myocardial infarction is reduced. Within 48 hours: The function of nerve endings gradually begins to recover; the sense of smell and taste become more sensitive to external substances. Within 72 hours: Bronchial spasm no longer occurs, breathing becomes much more comfortable, and lung capacity increases. 2 weeks to one month: blood circulation is stable; walking is steady and light; lung function improves by 30. 1 to 9 months: symptoms such as cough, sinus congestion, fatigue, shortness of breath are alleviated; new cilia appear on the mucosa of the trachea and bronchi, treatment The function of mucus is enhanced; phlegm is reduced, the lungs are cleaner, and the chance of infection is reduced; the body's energy reserves are increased; weight can increase by 2_3 kg.

Within 1 year: The risk of coronary artery disease is reduced to half that of smokers.

4. Psychological balance. Mental balance is the most important. To maintain psychological balance, we need to achieve the following points: three happiness: helping others, being content with what we have, and enjoying ourselves. Three Rightes: Treat yourself correctly, treat others correctly, and treat society correctly. Three requirements: not only to contribute to society wholeheartedly, but also to savor a beautiful life; to be enterprising in career but also to have a normal mind in life; to strive for excellence in one's job and to be multi-faceted. Colorful spare time life.

(3) The concept of health education

Since the early 1980s, when health education was officially introduced into our country, health education has been familiar to many people. Health education is an activity and process carried out by means of dissemination, education, and intervention, with the goal of helping individuals and groups change unhealthy behaviors and establish healthy behaviors, and with the purpose of promoting health.

Health education is to prevent and control diseases and promote health as the main starting point. Through planned, organized and systematic educational activities, it encourages people to voluntarily adopt behaviors that are beneficial to human health and eliminate or reduce risk factors. , reduce morbidity, disability and mortality, improve life and quality of life, and evaluate the effectiveness of education. The core of health education is to change people's behavior and lifestyle and the environmental conditions that affect behavior and lifestyle changes. Health education is a planned, purposeful and evaluated educational activity, not just radio and television, posters, slogans, etc. It emphasizes the mutual cooperation between health educators and those receiving education. Through the two Let’s work together to achieve the goal of health.

It is the unification of changing the knowledge, concepts and behaviors of education objects. The relationship between these three is as follows: knowledge is the foundation, faith is the driving force, and action is the goal. Its purpose is to eliminate or reduce risk factors that affect health, prevent disease, promote health and improve quality of life.

About Health Education Knowledge Lecture 2

Cerebral infarction is caused by cerebral atherosclerosis, intima damage of blood vessels narrows the cerebral artery lumen, and then local thrombosis occurs due to various factors. It is a cerebrovascular disease that aggravates arterial stenosis or completely blocks it, leading to ischemia, hypoxia, and necrosis of brain tissue, causing neurological dysfunction.

The main factors of cerebral infarction are: hypertension, coronary heart disease, diabetes, overweight, hyperlipidemia, and preference for eating fatty meat. Many patients have a family history. It is more common in middle-aged and elderly people aged 45 to 70 years.

Patients with cerebral infarction generally go through three stages: acute attack, recovery and sequelae. Comprehensive prevention and treatment for most patients during the recovery and sequelae phases is carried out at home. If effective drugs can be adhered to, Treatment, insisting on dietary regulation, insisting on rehabilitation training such as limb function, and controlling risk factors such as blood pressure and blood lipids can achieve the purpose of rehabilitation treatment that effectively improves symptoms and prevents recurrence.

Effective rehabilitation and health care treatment for patients with cerebral infarction should include the following points:

Diet: Eat more fiber-rich foods, such as various vegetables, fruits, brown rice, whole grains and Beans can help with defecation, prevent constipation, stabilize blood sugar and lower blood cholesterol.

Use vegetable fats and oils, and cook them by boiling, steaming, cold dressing, roasting, grilling, stewing, stewing, etc.; avoid fatty meat, offal, fish eggs, butter and other high-cholesterol foods; you can Choose fish and skinless chicken with less fat content; eat 1 to 2 whole eggs per week. Six major food categories, including milk and their products, grains and roots, meat, fish, beans and eggs, vegetables, fruits and oils, should be consumed in a variety of ways to fully obtain various nutrients.

Exercise: Appropriate amounts of physical exercise and physical activities should be carried out. It is not advisable to do strenuous exercise. Running and mountain climbing are not advisable. Walking, calisthenics, Tai Chi and other aerobic exercises can be carried out. However, the choice should be based on the individual's physical condition, and should not be excessive to avoid excessive fatigue.

Proper physical exercise can increase fat consumption, reduce cholesterol deposition in the body, and improve insulin sensitivity. It is beneficial to preventing obesity, controlling weight, increasing circulatory function, adjusting blood lipids, lowering blood pressure, and reducing blood clots. It is an important tool for preventing and treating cerebral infarction, cerebral embolism, Active measures for cerebral infarction.

Medication: The pathological basis of cerebral infarction is cerebral atherosclerosis. After the thrombus subsides, cerebral arteriosclerosis does not subside, and cerebral infarction may still re-form, so the functions of thrombolysis, blood stasis, and lipid lowering cannot be interrupted. Anticoagulant? Effective drug for treating cerebral infarction.

Traditional Chinese medicine:

Traditional Chinese medicine has definite clinical effects in preventing cardiovascular and cerebrovascular diseases, including traditional Chinese medicine that promotes blood circulation and removes blood stasis, aromatic resuscitation, and can lower blood pressure and lower blood pressure. It has the functions of viscosity, improvement of microcirculation, antioxidant, anti-thrombosis, elimination of blood stasis, etc. It is suitable for the treatment of symptom recovery and prevention of recurrence in patients with cerebral infarction.

Aspirin: Mainly inhibits platelet aggregation and release, improves the balance of prostaglandins and thromboxane A2, and prevents thrombosis. The disadvantage is that 47% of patients develop drug resistance.

Risk factor control:

High blood pressure: It can accelerate and aggravate the development of arteriosclerosis. The higher the blood pressure, the greater the chance of cerebral infarction or recurrence of cerebral infarction.

Hyperlipidemia: On the one hand, it makes the blood thicker, slows blood flow, and reduces the amount of blood supply to the brain; on the other hand, it damages the vascular endothelium and deposits on the blood vessel wall to form atherosclerotic plaques, which directly leads to cardiovascular and cerebrovascular diseases. The occurrence and development of disease. Diabetes: Diabetes above 80% leads to abnormal lipid metabolism, often accompanied by arteriosclerosis, hyperlipidemia and cardiovascular and cerebrovascular diseases; and increased blood glucose content will also increase blood viscosity and coagulation, which is conducive to the formation of cerebral infarction.

Heart disease: Blood to the brain comes from the heart. When myocardial infarction or heart failure occurs, the blood supply to the brain is insufficient, which can cause cerebral infarction; when rheumatic heart disease is combined with atrial fibrillation and other arrhythmia attacks, the emboli in the atria fall off and enter the cerebral blood vessels, which can cause cerebral embolism.

Symptoms and signs:

1. The onset is extremely acute, and symptoms often reach their peak in a few seconds or a short period of time, and a few show progressive deterioration in a stepwise manner.

2. Some patients have temporary confusion, headache, and convulsions. Secondary cerebral edema that occurs within a few days after large artery occlusion can worsen symptoms and lead to disturbance of consciousness. Severe cerebral edema can also cause fatal disease. Risk of displacement of intracranial structures (herniation).

3. Local symptoms and signs of the nervous system occur suddenly.

4. Internal carotid artery: It can cause blindness in the ipsilateral eye. Other symptoms are often difficult to differentiate from the symptoms and signs that occur after occlusion of the middle cerebral artery and its deep perforating branches.

5. Anterior cerebral artery: Uncommon, one side can cause contralateral hemiplegia (lower limbs heavier than upper limbs), strong grip reflex and urinary incontinence. Bilateral involvement can cause apathy, confusion, and occasionally mutism and spastic paraplegia.

6. Posterior cerebral artery: There may be homonymous hemianopsia, contralateral hemispheric sensory loss, spontaneous thalamic pain, or sudden involuntary hemiconvulsions; alexia may be seen when the dominant hemisphere is involved. disease.

7. Vertebro-basilar artery: dizziness, diplopia, eye movement paralysis, ataxia, crossed paralysis, pupillary abnormalities, quadriplegia, difficulty in eating and swallowing, disturbance of consciousness and even death.

8. The middle cerebral artery and its deep perforating branches: are most susceptible to involvement, with contralateral hemiplegia (severe degree), hemiparalysis (sensory loss), homonymous hemianopsia, and the dominant hemisphere (usually the left Aphasia may occur when the side) is affected, and apraxia may occur when the non-dominant hemisphere is affected.

Signs of onset:

1. Dizziness and headache suddenly worsen or change from intermittent headache to persistent severe headache. It is generally believed that headaches and dizziness are mostly the precursors of ischemic cerebral infarction, while severe headaches accompanied by nausea and vomiting are mostly the precursors of hemorrhagic cerebral infarction.

2. Transient visual impairment, manifested as blurred vision, or visual field loss, and incomplete vision. This phenomenon usually recovers within one hour and is an early warning signal for cerebral infarction.

3. Language and mental changes refer to difficulty in pronunciation, aphasia, and difficulty in writing; sudden changes in personality, such as taciturnity, indifferent expression, or irritable multilingualism, irritability, or short-term judgment or mental retardation, and lethargy.

4. Other aura symptoms, such as nausea, vomiting or strangulation, or blood pressure fluctuations accompanied by dizziness or tinnitus, unexplained repeated nosebleeds, are often the recent precursors of high blood pressure and cerebral hemorrhage. .

5. Drowsiness and lethargy, manifested as yawning repeatedly, especially in response to hypoxia in the respiratory center. As cerebral arteriosclerosis worsens, the arterial lumen becomes narrower and narrower, and cerebral ischemia seriously worsens. About 80 people yawn frequently 5 to 10 days before the onset of ischemic cerebral infarction. Therefore, do not ignore this An important alarm signal.

6. Somatic sensory and motor abnormalities, such as episodic unilateral numbness or weakness of limbs, loss of objects in hand, unexplained fainting or falling, unilateral facial paralysis, lasting less than 24 hours. Follow-up observation shows that 3 to 5 years after this phenomenon occurs, more than half of the people will suffer from ischemic cerebral infarction.

7. Melanoma fugax refers to a normal person who suddenly experiences black eyes and cannot see objects, and then returns to normal within a few seconds or minutes, without nausea, dizziness, or any disturbance of consciousness. This is caused by transient retinal ischemia, which indicates changes in intracranial hemodynamics or temporary obstruction of retinal arteries by tiny thrombus, which is the earliest warning signal of cerebrovascular disease.

How to prevent cerebral infarction:

1. Don’t overwork yourself. Overwork or poor rest can easily cause blood pressure fluctuations and cause cerebral thrombosis.

2. Eat a light diet, mainly vegetarian food, and eat less high-fat foods. Eat 500 grams of vegetables, 250 grams of fruits, and 250 ml of milk every day.

3. Quit smoking and limit alcohol consumption. Smoking and alcohol can damage the intima of blood vessels and cause small blood vessels to contract and narrow the lumen, making it easy to form thrombus.

4. Emotionally stable. Anger or long-term depression and anxiety can cause disorders of vascular neuroregulation and are important causes of cerebral infarction.

5. Diabetic patients with increased blood viscosity need to control blood sugar and reduce blood viscosity.

6. For patients who have suffered from cerebral infarction, it is recommended to take long-term low-dose aspirin while monitoring blood viscosity and cerebral blood vessels to prevent recurrence.

7. Control blood pressure. Patients with high blood pressure must take antihypertensive drugs for a long time and monitor their blood pressure frequently. They should not take medicine based on whether they are dizzy or headache.

Dietary adjustments for patients with cerebral infarction:

1. Control total calories. If total fat intake is controlled in the diet, blood lipids will decrease.

2. Limit the intake of refined sugar and sugary sweets, including snacks, candies and drinks.

3. Patients with cerebral infarction should use less salt and adopt a low-salt diet, with 3 grams of salt per day. You can add salt and mix well after cooking.

4. Patients with cerebral infarction should drink water frequently, especially in the early morning and evening. This thins the blood and prevents blood clots from forming.

5. Pay attention to the cooking ingredients. In order to increase appetite, you can add some vinegar, tomato sauce, and sesame sauce when cooking. In addition to being a seasoning, vinegar can also accelerate the dissolution of fat and promote digestion and absorption. Tahini has high calcium content. Regular consumption can supplement calcium and has certain benefits in preventing cerebral hemorrhage.

Lecture on Health Education Knowledge Part 3

In order to improve the health awareness of rural residents, let rural residents understand the concept of health, factors affecting health and healthy lifestyles, and establish a healthy life concept.

It has been decided to hold a lecture on health education knowledge. The notice is as follows:

Location: Health Education Office, Zhengjixiang Health Center

Lecture content: Establishing the concept of health

Lecturer: Wang Bingjun

Participants: Public health department staff and all rural doctors

Healthy lifestyle and behavior

Speaker: Wang Bingjun

1. The diet should be mainly based on cereals, eat more vegetables, fruits and potatoes, and pay attention to the combination of meat and vegetables.

Cereal food is the main body of the traditional diet of our residents. It is the best basic food for human beings and the most economical source of energy. Cereal-based meals can not only provide sufficient energy but also avoid excessive fat intake, and are beneficial to the prevention of cardiovascular and cerebrovascular diseases, diabetes and cancer. The "Dietary Guidelines for Chinese Residents" states that adults should consume 250g to 400g of cereals every day.

Vegetables and fruits are important sources of vitamins, minerals, dietary fiber and phytochemicals. Potatoes are rich in starch, dietary fiber and a variety of vitamins and minerals. Vegetables, fruits and potatoes play an important role in maintaining good health, maintaining normal intestinal function, improving immunity, and reducing the risk of chronic diseases such as obesity, diabetes, and hypertension. The "Dietary Guidelines for Chinese Residents" points out that adults should eat 300g to 500g of vegetables and 200g to 400g of fruits every day.

Food can be divided into cereals (rice, noodles, cereals, etc.) and potatoes, animal foods (meat, poultry, fish, milk, eggs, etc.), beans and nuts (soybeans, other dry beans, etc.) (foods, peanuts, walnuts, etc.), vegetables, fruits, and pure energy foods (animal and vegetable oils, starch, sugar, wine, etc.). The nutrients contained in various foods are not exactly the same. Each food can provide at least one nutrient. No natural food can provide all the nutrients needed by the human body. A diet composed of a variety of foods can meet the various nutritional needs of the human body, achieve the purpose of reasonable nutrition and promote health.

2. Regularly consume milk, beans and their products.

Dairy foods have complete nutrients, suitable nutritional composition ratio, are easy to digest and absorb, and are an excellent source of dietary calcium. Drinking milk for children and adolescents is beneficial to their growth and development and bone health, thus delaying the onset of osteoporosis in adulthood; drinking milk for middle-aged and elderly people can reduce bone loss and is beneficial to bone health. It is recommended that each person drink 300 grams of milk or an equivalent amount of dairy products per day. People with high blood lipids and overweight and obesity should choose reduced-fat, low-fat, skimmed milk and their products.

Soybeans are rich in high-quality protein, essential fatty acids, B vitamins, vitamin E and dietary fiber and other nutrients. They also contain phospholipids, oligosaccharides, isoflavones, plant sterols and other nutrients needed by the human body. Phytochemicals. Eating more soybeans and their products appropriately can increase the intake of high-quality protein and prevent the adverse effects of excessive consumption of meat. It is recommended that each person consumes 30 to 50 grams of soybeans or an equivalent amount of soy products per day.

3. The meals should be light and less salty.

Excessive intake of edible oil and salt is a common dietary problem for urban and rural residents in my country. Excessive salt intake is closely related to the prevalence of hypertension. Fat is one of the important sources of energy for the human body, but excessive fat intake can increase the risk of obesity, hyperlipidemia, atherosclerosis and other chronic diseases. You should develop the habit of eating light and low-salt meals, that is, the meals should not be too greasy, not too salty, and do not eat too much animal foods and fried, smoked, and pickled foods. It is recommended that the daily cooking oil consumption per person should not exceed 25 grams; the salt intake should not exceed 6 grams (including the salt content in soy sauce, pickles, and sauces).

4. Maintain a normal weight and avoid overweight and obesity.

Whether your weight is normal can be judged by body mass index (BMI). The normal weight of adults refers to a body mass index between 18.5 kg/m2 and 23.9 kg/m2.

The calculation formula is: BMI= weight (kilogram)/height (meter) 2 Overweight and obesity are one of the main reasons for the increased prevalence of cardiovascular disease, diabetes and certain tumors. Food intake and exercise are the two main factors in maintaining a healthy weight. Food provides the body with energy, and exercise consumes energy. If you eat too much and don't exercise enough, the excess energy will be stored in the body in the form of fat, increasing your weight, leading to overweight or obesity. On the contrary, if you don't eat enough, it can lead to underweight or weight loss due to lack of energy. Both being overweight and underweight are unhealthy symptoms, making you susceptible to a variety of diseases and shortening your lifespan. Therefore, a balance between food intake and exercise should be maintained so that the energy provided by the various foods ingested can meet the needs of the body without causing excess energy in the body, so that the body weight can be maintained within an appropriate range.

5. After falling ill, you should seek medical treatment promptly, cooperate with the doctor’s treatment, and take medication according to the doctor’s instructions.

After getting sick, you should seek medical treatment promptly, diagnose and treat early, and avoid delaying the best time for treatment. This can not only reduce the harm of the disease, but also save the cost of medical treatment.

In the process of disease treatment and recovery, you must strictly follow the doctor’s treatment plan and actively cooperate with the doctor’s treatment. You must follow the doctor's instructions, take medicines on time and in the right amount, prepare your diet, determine your activity level, and improve your behavior according to the doctor's requirements. Do not seek medical treatment randomly and use several treatments at the same time, nor should you buy medicine on your own based on partial knowledge and hearsay.

6. Do not abuse antibiotics.

Abuse of antibiotics refers to irregular use, unnecessary use, overtime and excessive use, insufficient dosage or insufficient course of treatment, etc. The misuse of antibiotics can easily lead to drug resistance of pathogenic microorganisms, causing antibiotics to gradually lose their original efficacy and fail to treat diseases. Abuse of certain antibiotics may also lead to deafness (especially in children) and imbalance of flora in the human body, which may even be life-threatening in severe cases.

Antibiotics are prescription drugs and can only be used rationally under the guidance of a doctor. 42. Food must be cooked; vegetables and fruits must be washed before eating raw.

The food should be cooked thoroughly before eating. When eating leftovers in the refrigerator, reheat them thoroughly before eating. Tableware such as bowls and chopsticks should be boiled and disinfected frequently.

Raw vegetables and fruits may be contaminated with pathogenic bacteria, parasite eggs, and toxic and harmful chemicals. Before eating raw, it should be soaked for 10 minutes and then washed thoroughly with clean water.

7. Raw and cooked foods should be stored and processed separately.

During food processing and storage, if you do not pay attention to separating raw and cooked food, for example, use a knife that has been used to cut raw food before cutting cooked food, and use a container that has been used to hold raw food before placing cooked food. , cooked food may be contaminated by bacteria and parasite eggs on raw food, harming human health. Therefore, raw and cooked foods should be placed and processed separately to avoid direct or indirect contact between raw and cooked foods.

8. Do not eat food that has gone bad or has expired.

Food shelf life refers to the period during which food quality (quality) is maintained under the conditions marked on the food label. Within this period, the food quality meets the specifications on the label or in the product standard.

Any food has a shelf life. If stored for too long or improperly, it will become contaminated or deteriorate. Contaminated or spoiled food cannot be eaten. Food will deteriorate if kept in the refrigerator for a long time; when storing food in the refrigerator, be sure to separate raw and cooked foods, and store cooked foods covered.

Don’t eat expired food. Do not eat food that does not have the exact manufacturer's name, address, production date and shelf life on the label.
