Food prevention

It should be noted that because some food prevention can only increase the probability of successfully preventing diseases by increasing the nutritional content of the body, it cannot specifically target a specific disease. Diseases can be effectively prevented, so the following so-called food prevention has not been confirmed by clinical experiments and is subjective. People with allergies should consider it carefully.

1. Garlic: Garlic has antibacterial and anti-inflammatory effects, can protect the liver, regulate blood sugar, protect cardiovascular, resist hyperlipidemia and arteriosclerosis, and resist platelet aggregation. Nutrition experts have found that garlic extract has anti-tumor effects and recommend eating 3-5 grams of raw garlic every day.

2. Aloe: Aloe is a perennial herbaceous plant of the Liliaceae family like goldenrod, garlic, onion and wild lily. It mainly grows in dry and hot areas. It has strong vitality and can clear away heat, detoxify, relieve diarrhea, It is anti-inflammatory and antibacterial, enhances immunity, and can also protect the stomach, liver and skin care.

3. Lentinus edodes: Improve the body’s immune function. Lentinan can improve the phagocytosis function of peritoneal macrophages, promote the production of T lymphocytes, and increase the killing activity of T lymphocytes;

4. Tomato: rich in vitamins, minerals, carbohydrates, organic acids and a small amount of protein. It has the functions of promoting digestion, diuresis and inhibiting various bacteria. At the same time, studies have concluded that tomatoes contain carotenoids that can produce vitamin A, mainly α-carotene and β-carotene. Ingesting tomato juice for a period of time will significantly increase the lycopene in the body, and at the same time, the immune function of T lymphocytes will be enhanced.

5. Fresh radish: It has an immune effect because it is rich in interferon inducers.

6. Fresh royal jelly: Contains royal jelly acid and antibacterial active substances, which has strong bactericidal and antibacterial effects and can effectively improve and enhance human immune function.

3. The diet should be more sweet and less sour: sweet foods should be eaten in spring to strengthen the spleen and stomach, warm and replenish yang energy; the liver controls hair growth, and is related to spring. Correspondingly, acid enters the liver and eating less acidic food can not only prevent excessive growth of Yang Qi, but also nourish the liver and improve disease resistance.

If the avian influenza virus is inhaled into the respiratory tract, at the same time This disease occurs when the body feels very cold for a long time. When the body is cold, people's resistance can only resist the cold. The cold directly acts on the body, greatly reducing or disappearing the body's ability to resist the reproduction of germs and viruses in the body. At this time, the germs and viruses will multiply rapidly in the body until the disease occurs. , this is how common cold and flu viral diseases occur.

(1) What is influenza (H7N9) virus? Influenza H7 viruses are typically a group of influenza viruses that circulate among birds. Influenza virus (H7N9) belongs to a subgroup of the H7 virus family. Although there are occasional reports of certain H7 viruses (H7N2, H7N3, H7N7) infecting humans, there have been no reports of human infection with H7N9 viruses in the past until such cases were recently reported in China. (2) What are the main symptoms of human infection with H7N9 virus? So far, patients infected with the H7N9 virus have developed severe pneumonia, with symptoms including fever, cough, and difficulty breathing. However, knowledge of the full range of symptoms that may occur after infection with the influenza A (H7N9) virus is still limited. (3) Why can poultry viruses now infect humans? At this time, we do not know the answers to these questions because the source of human exposure to the virus is unknown. However, genetic analysis of the virus showed that although the virus evolved from avian influenza viruses, it showed characteristics that could be adapted to grow in mammals. These adaptations include the ability to bind to mammalian cells and grow at temperatures close to the normal body temperature of mammals, which is lower than that of birds. (4) How to prevent influenza (H7N9) virus infection? Although the source of infection and mode of transmission cannot yet be determined, it is prudent to adopt the following basic hygiene behaviors to prevent infection. They include hand hygiene, respiratory hygiene, food safety measures. ①Hand hygiene: Wash hands before, during and after preparing food; before eating; after using the bathroom; handling animals or animal excrement; when hands are dirty; and when caring for patients at home.
