Does selenium supplementation slow down aging? What is the role of selenium supplementation?

Selenium is an essential nutrient for delaying aging, is one of the most important mineral nutrients in the human body, all the effects of selenium are based on resisting free radicals and improving immunity, which can effectively alleviate the symptoms related to ** disease. At present, the role of selenium in psoriasis and ultraviolet radiation on ** damage has attracted much attention in the academic community.

Selenium destroys the peroxides existing in the body through the action of glutathione peroxidase in the cell, prevents the formation of harmful free radicals and attacks on unsaturated fats, which not only has an effect on the cells of the whole body, but also has an effect on epidermal cells and subcutaneous tissues, which can delay the aging and death of **; Selenium and vitamin E synergize with each other to prevent cell aging and increase elasticity, selenium can also antagonize the toxicity of lead, reduce the toxic effect of lead-containing cosmetics, and protect ** from harm, so selenium supplementation is beneficial to beauty.

Elderly people with poor resistance are often susceptible to some influenza diseases when the weather changes abruptly in spring. Health experts remind everyone that the focus of spring immunization is on selenium supplementation, and the elderly who are frail and sick should pay more attention and attention. Below, health experts will tell you that in daily life, there are many ways to supplement selenium for the elderly.

The two most commonly used are dietary therapy and medicinal therapy, among which dietary therapy is more widely used. In terms of dietary therapy, selenium-rich foods that can be eaten regularly are: sesame seeds, garlic, asparagus, mushrooms, prawns, sardines, liver, kidneys, wheat bran, onions, tomatoes, broccoli, celery, straw mushrooms, milk, etc.

There are various methods of selenium supplementation, which can take the form of dietary therapy and medicinal therapy, and dietary therapy should be the main method. Foods rich in selenium are: sesame seeds, garlic, asparagus, mushrooms, prawns, sardines, etc.

If it is really necessary to seek medical treatment, the elderly can also appropriately supplement organic selenium such as selenium eggs, selenium-rich mushrooms, and selenium-rich rice.

If the elderly are more deficient in selenium, it is best to take health products refined with organic selenium malt and natural vitamin E as the main raw materials. And the product should reach a natural level, hormone-free, safe and non-toxic.

At present, more than 490 diseases that have been verified are caused by selenium deficiency, especially by the elderly who are a high-risk group of diseases, selenium deficiency may lead to diabetes, cardiovascular disease, acute myocarditis and other diseases. In addition, cataracts and glaucoma suffered by some elderly people are also related to selenium deficiency. International nutrition experts have long pointed out that a daily intake of 200 micrograms of selenium can effectively prevent the occurrence of cancer.

More than 300 micrograms can have a certain effect on cancer. It is recommended that the elderly can supplement selenium by taking health supplements, but it should be noted that eating too much selenium will also be detrimental to health.

Hello, eggs contain more selenium than meat. The selenium content of plant foods is determined by the selenium content of local water and soil, for example, Bama in Guangxi and Ziyang in Shaanxi are both high-selenium areas, and selenium-rich tea from 100,000 mountains can be used to supplement selenium. Selenium-rich foods are first recommended goldenrod tea, sesame, malt and Chinese herbal medicine astragalus, followed by yeast, eggs, beer, seafood to red shrimp, lobster, tiger clawfish, tuna, etc., and then animal liver, kidney and other meat, and fruits and most vegetables do not contain much selenium, but the content of garlic and mushrooms is quite large, and asparagus contains selenium.

Please give me a good review, thank you.

[The effect of selenium on the human body]:

Selenium has the toxic effect of antagonizing heavy metals such as cadmium and mercury, and forms compounds that are difficult to dissociate, so that the adverse biological effects of cadmium and mercury are reversed, so as to exert a detoxification effect. In addition, selenium is also involved in the body's material metabolism and energy metabolism, participates in phage defense, and is related to immune mechanisms.

Proper dietary selenium content is one of the important factors in maintaining health under stressful conditions. The physiological functions of selenium are also manifested in the following aspects: it participates in the maintenance of immune function and protects cell membranes and cells.

Promotes the growth and reproduction of the body. Protects cardiovascular and myocardial health. Selenium can reduce the incidence of cardiovascular disease, and can also reduce or disappear angina; Increase energy and productivity.

Selenium can prevent the occurrence of Keshan disease, which is related to endemic selenium deficiency in China.

Selenium can reduce the toxicity of aflatoxins and relieve the toxic effects of heavy metals in the body. Selenium has a strong affinity for heavy metals and is a natural antidote against heavy metals. Selenium binds to metals in the body to form complexes, which detoxify and excrete metals.

Selenium protects eyesight and the function of the visual organs. Selenium-containing glutathione peroxidase and vitamin E reduce the degree of oxygen damage on the retina. Blindness in diabetics can be improved with selenium, vitamins E and C.

Selenium has antitumor effects. An appropriate amount of selenium can inhibit the occurrence and development of a variety of chemical carcinogens caused by animal liver cancer, ** cancer and lymphosarcoma. Diseases such as breast cancer, colon cancer, rectal cancer, prostate cancer, ovarian cancer, urinary tract tumors, and leukemia are all related to selenium deficiency in the environment.

Ways to supplement selenium]:

Foods that contain more selenium in daily life include seafood, animal offal, lean meat, rice, cereals, etc. The amount of selenium in traditional Chinese medicine Dilong is also more. Almost all of the selenium in the body comes from food, but due to the different biochemical characteristics of each person, the surrounding environment and other factors, the intake of selenium also varies from person to place.

In addition to wheat germ, garlic, asparagus, mushrooms and sesame seeds, selenium-rich foods also include many seafood products such as prawns, tuna and sardines. In addition, there are some plants that are particularly rich in selenium, such as astragalus, sedge, asters, quinoa and alfalfa. For example, goldenrod contains 10 mg of selenium per gram, alfalfa can reach 32-122 micrograms, and vegetables of the cruciferous family cabbage also have a strong ability to accumulate selenium.

However, because food will also lose part of selenium due to volatilization during cooking and heating, if the elements required by the human body are not consumed enough from food, they can be supplemented by safe health care preparations. For example, high bioavailability, non-selenium power chewable tablets, comprehensive supplementation of corn selenium and vitamins, corn selenium conversion and absorption is good, and vitamins can prevent excessive selenium supplementation and avoid selenium poisoning.

Selenium supplementation is a long-term process, and selenium, like other nutrients, participates in the body's metabolism and is constantly converted, utilized and excreted by the body. Selenium is also an element that is easy to excrete, whether the selenium absorbed into the body will always exist in the body, determined by experts, the human body's selenium will be reduced by half within 11 days, indicating that the metabolism of selenium is relatively fast, can be continuously absorbed, and constantly discharged, indicating that the human body needs to continuously replenish selenium.

Adequate amounts of selenium must be supplemented throughout life to have a high ability to prevent cancer and disease, and if selenium supplementation is stopped, the ability to defend against disease will be reduced. Selenium can fight free radicals, improve immunity, and protect the body from foreign harmful substances. However, the human body itself can not synthesize selenium, the human body's "metabolism" needs selenium mainly in food, animal organs and poultry eggs contain high selenium, but fat and cholesterol are also high, people should not eat more; Shrimp and crab and other seafood have high selenium content, but the utilization rate of the human body is low; Grains, vegetables and fruits are low in selenium and do not contribute much to the body's selenium intake.

In addition, China has a low selenium zone from the northeast (such as Heilongjiang) to the southwest (Sichuan, Yunnan), where the selenium content of the food produced there is low. It is generally recommended to drink 100 micrograms of plant-active selenium every day, and the selenium-rich corn flour of pure grains is not harmful to the body, and if it is not a special diet, it is easy to cause dietary selenium insufficiency.

Selenium deficiency in the human body can easily lead to cardiovascular and cerebrovascular diseases. Epidemiological investigations have confirmed that selenium deficiency is closely related to atherosclerosis, coronary heart disease and hypertension. The incidence of cardiovascular and cerebrovascular diseases in selenium-deficient areas in the United States is 3 times higher than that in high-selenium areas, and the incidence of cardiovascular and cerebrovascular diseases in selenium-rich areas is 67% lower than the national average.

Clinical medical studies in China have also confirmed that the blood selenium concentration of patients with acute myocardial infarction is significantly lower than that of healthy people.

The effects of selenium on human health are extensive, with a variety of immune and biological functions, especially its anti-tumor and anti-toxic diseases and anti-aging effects on cardiovascular diseases. In recent years, it has attracted special attention, and research has confirmed that selenium is the activity center of a variety of enzymes, which plays a role in resisting diseases, preventing aging, and enhancing immune function in life activities.

The contribution of selenium to human health can be summarized as follows:

1. Antioxidant effect: selenium can reduce toxic peroxides to harmless substances, decompose peroxides, remove free radicals, protect the structure and function of cell membranes, repair molecular damage, and increase immunity;

2. Promote a variety of metabolic activities in the body and promote growth;

3. Cardiovascular: selenium is a normal component of muscle, selenium deficiency will cause skeletal muscle atrophy, myocardial damage, until it increases, calcium deposition, selenium supplementation can prevent the occurrence of a variety of diseases, protect cardiovascular and myocardial health, and reduce the incidence of cardiovascular diseases;

4. Resist and reduce the toxic effect of a variety of heavy metals, and can form insoluble substances with important metals such as silver, mercury, lead, etc., which has a certain effect on the human body to resist metal pollution in the environment.

5. Protect the healthy function and vision of the optic organs;

6. Improve the body's immunity.

Regulates the cell proliferation cycle and mainly kills tumor cells in the proliferative phase.

Induces apoptosis of tumor cells without inflammation.

Adjuvant chemotherapy to enhance the sensitivity of chemotherapy drugs.

Reverse tumor drug resistance and enhance the efficacy of traditional chemotherapy.

Reduce chemotherapy toxicity*** and increase the number of white blood cells.

Induce tumor cells to differentiate into normal cells.

Prevent metastasis of tumors.

Prevents **stage tumors**.

Balances the immune system and prevents cancer.

Selenium has many functions, such as improving human immunity, anti-oxidation and anti-aging, participating in diabetes, anti-cancer and anti-cancer, protecting eyes, protecting and repairing cells, improving the shoe oxygen capacity of red blood cells, preventing and treating cardiovascular diseases, detoxification, anti-poison and anti-pollution, protecting the liver and so on. The trace element selenium is not much in the human body, about 3-20 mg, but the effect is huge.

It is an over-the-counter drug, generally speaking, there are no contraindications, that is to say, normal people will not have much effect on taking it, but if you are allergic to selenium or allergies, then, it is recommended not to choose to take it to help improve the problem, otherwise it is likely to cause harm to the body because of taking it.

Clause. Second, the *** of selenium tablets.

Although normal people can take it, however, this does not mean that it will not exist after taking it, if you take it for a long time, it is likely to cause hair loss or nail deformation, if the problem is serious, it will also lead to liver damage, and even death, therefore, it is recommended that you ask your doctor before taking it, how long to take it to avoid being troubled.

Clause. 3. How to eat selenium tablets.

The correct way to take it is to take two to four tablets each time, once to two times a day, the specific amount of medicine will be determined according to the patient's condition, generally speaking, cardiovascular and cerebrovascular patients can take two tablets, liver disease patients need to take two to three tablets, and diabetic patients take two pills, if it is a cancer patient, then take four pills.

1 patient with liver disease, 2 patients with cardiovascular disease, 3 patients with diabetes, 4

Gastrointestinal patients 5 people who are prone to fatigue and those who have been addicted to tobacco and alcohol for many years!

People living in areas with high selenium intake and already high selenium intake should not supplement with selenium, because excessive selenium intake can cause some toxic symptoms. Because selenium itself is a trace element, it should not be oversupplemented.

People in areas with high selenium should be cautious about selenium supplementation. People who have excess selenium in their bodies should also not be supplemented.

People who are healthy and do not lack selenium cannot supplement selenium, and excessive selenium supplementation will cause poisoning.

Uh, hello, if you can't hide from calcium, you can't make up for those who can't be sunburned to the point of being afraid of the sun.
