In order to enhance immunity, many people are used to eating health food to keep fit. Be careful that too much may be harmful to health. People's immune system is complex, so how does the health food you eat work? Which part of the body will it affect? There is no conclusion yet; And most health foods are processed, not natural foods. It is suggested that it is best to choose unprocessed fresh fruits and vegetables to ensure health.
Common health food for enhancing immunity
There are hundreds of immune health foods on the market, which one is the best? Li Wanping, a nutritionist, said that many health foods claimed to have been endorsed by domestic and foreign research reports and had certain effects on animal experiments such as immunomodulation or improvement of liver function. In fact, the effectiveness of animals does not mean that people have the same effect; Moreover, everyone's physique is different, and eating health food has different effects on immunity.
For example, after receiving treatment, cancer patients are prone to side effects such as a sudden drop in the number of white blood cells and low immunity; Patients with lupus erythematosus have high immunity and attack their own immune system. Therefore, health food may be effective for relatives and friends, but it may not be suitable for yourself. Li Wanping suggested that people can try it for three to six months, and if it doesn't work, stop eating it to avoid wasting money.
There are many kinds of health foods in the market, such as ginseng, clam essence, ganoderma lucidum, Antrodia camphorata, mushrooms, ginkgo and so on. Among them, there are many studies on ginseng (red ginseng is pickled), especially a series of studies on Korean ginseng found that it has an effect on joint inflammation.
▌ Ginseng:
Since ancient times, ginseng has been considered to have the function of enhancing immunity and invigorating the spirit. The older generation often sliced ginseng and drank it in water. In fact, ginseng has a complex composition and contains ginseng soap? Rg 1、Rg2、Rg3？ Wait, the key mechanism is not clear. However, many studies have found that ginseng can really stimulate immunity, and it can affect immune-related macrophages through two inflammatory factors; In addition, TNF-α is related to tumor necrosis factor. Many people feel much better after eating it. They are not easy to catch a cold, their blood circulation has improved and their sexual function has improved. Clinically, someone once soaked 1 or 2 pieces of ginseng every day. This regimen has been soaked for twenty or thirty years without interruption.
However, when eating ginseng, you should also pay attention. Because of the hot weather, eating too much is easy to constipation, and I can't sleep at night. People who are over-immunized may have the opposite effect once they eat too much ginseng. Li Wanping said, "Too much or too little immunity is not good." Usually, people with blood pressure of120 ~140mmhg can try to take ginseng to adjust their immunity. However, if the blood pressure is too high (above140mm Hg), it is not recommended to eat American ginseng, and it will not be affected. In addition, people in an inflammatory state had better not eat ginseng.
▌┄essence:
Clam essence is a health food that has been vigorously promoted in TV advertisements in recent years. Meretrix meretrix, commonly known as clam, is regarded as a sacred product for anti-fatigue and liver protection. Because of the positive and negative comments of the paper, it is suggested that people may wish to choose products with health food certification to ensure the quality is guaranteed; Moreover, this certificate is best only for a certain batch of products, not a certificate for five years, so the safety of each batch of products cannot be guaranteed, making health certification a mere formality.
It is worth noting that the extract of Meretrix meretrix is taken from seafood, which is easy to have high sodium content, just like the truth that preserved fruit must be salted. Therefore, patients with hypertension should pay attention to sodium intake when eating Meretrix meretrix extract. The Consumer Culture and Education Foundation found that the sodium content of 6 samples in 12 was much higher than the marked value. In addition, seafood may have the problem of heavy metal pollution. If you want to eat health food to enhance your immunity, you should consider your priorities in advance, choose the way that is most beneficial to your health, or you need manufacturers to provide heavy metal detection reports.
▌ Ganoderma:
Ganoderma lucidum contains polysaccharide ganoderic acid, which has antiallergic and anti-inflammatory effects. In addition, the small molecule LZ-8 protein and nucleic acid in Ganoderma lucidum can produce similar immunoglobulins and provide the ability to activate macrophages, and its function is similar to that of immune-related IL-2 interferon. Many scientists at home and abroad are actively participating in the research on the efficacy of Ganoderma lucidum, which means that Ganoderma lucidum itself does have certain therapeutic significance.
But ganoderma lucidum is not omnipotent, especially for improving cancer immunity. Remind cancer patients that if the white blood cell count is very low during treatment, consider whether they can eat Ganoderma lucidum to enhance their immunity. There are always patients who will try it in clinic, but the effect needs more experimental evidence. Cancer patients are still very weak in the recovery period after treatment. Before eating Ganoderma lucidum, it is best to make sure that the raw materials are not polluted or that the production process is safe, so as to avoid spending a lot of money on Ganoderma lucidum, which is not good for your health.
▌ Niu Zhangzhi:
Is Niu Zhangzhi three years old? In order to understand the efficacy of Antrodia camphorata, the researchers first damaged the liver of mice, and then gave Antrodia camphorata. The results showed that the liver function index (GPT) of mice decreased. But unlike Ganoderma lucidum, there is no natural food to eat, so people should pay attention to the risk of food processing when buying.
Dance mushrooms:
Besides Antrodia camphorata, maitake is a very popular healthy food in recent years. It is a Japanese mushroom, which was introduced from Japan and planted in China. There have been studies on the application of D- fraction to patients with breast cancer, and it seems that it has significant anticancer activity and can help fight cancer. However, more experimental evidence is needed, and it is impossible to completely determine whether it is effective. However, D-fraction is edible, at least it is safer to eat.
▌ Ginkgo:
Many people will take health food made of Ginkgo biloba leaves to prevent Alzheimer's disease or increase peripheral blood circulation and improve hearing loss.
Li Wanping said that Ginkgo biloba, also known as ginkgo biloba, contains bitter lactone and flavonoids, which can promote vasodilation and regulate blood circulation. Because it can increase the content of carbon monoxide in the body, relax blood vessels, improve blood circulation, and further help the brain to increase the content of dopamine, thus preventing dementia, improving hearing, and reducing numbness in hands and feet or cold limbs.
Ginkgo biloba has many advantages. When the blood circulation is improved, the body will naturally be strong and the immunity will be improved. In addition to using medical-grade therapeutic drugs, eating ginkgo biloba is a good way. It is suggested that ginkgo can be cooked, such as fried ginkgo with tremella or fried pork slices with ginkgo lily. , is a delicious and healthy nutritious dish.
However, it should be reminded that although some health foods can enhance immunity, health foods are processed products after all, not pure natural ingredients, and the true colors of fruits and vegetables cannot be seen; Moreover, most of them are extracts of plant fruits and vegetables, plus many other nutrients, and then made into buccal tablets, capsules, powders, liquids and so on. People can't guarantee that the processing is completely pollution-free. For example, a manufacturer claims that a commodity is an extract of ginsenoside or Ganoderma lucidum, but are the raw materials really extracted from natural materials? If the extracted ingredients are not the key ingredients, is there any difference in the effect of health food? Can the action mechanism of various active ingredients be confirmed to act only on specific parts of the body? The effect of health care products also varies from person to person.
"Doctors diagnose medicine and nutritionists diagnose lifestyles. Li Wanping emphasized that there is no medical insurance for food processing. Consumers should eat natural fresh ingredients and supplement their immunity in the right place, which is the only way to stay healthy forever. People may wish to choose onions containing phlogiston nutrients, or cruciferous natural fruits and vegetables such as cabbage, which will help improve immunity.
