At present, the incidence rate of cancer in our country is getting higher and higher, and people are also becoming more and more frightened, worried that they may accidentally suffer from cancer. Therefore, when people can meet their daily food and clothing, they begin to pay attention to the topic of "health preservation", hoping to achieve the effect of resisting cancer and improving immunity through health preservation.
Among the various ways of health preservation, diet health preservation is nothing more than supplementing various nutrients into the human body through diet. So, there are thousands of nutrients, which should we give priority to?
Selenium, which stands out from many nutrients, has become a priority supplement for people in the process of health preservation. So, today I'm going to take you to know, is selenium really an essential element to fight cancer and improve immunity?
1、 Is selenium an essential element to fight cancer and improve immunity?
To prevent cancer, people first need to improve their immunity. If immunity is poor, the risk of cancer will increase.
Recently, there is a saying: "selenium is an essential element if you want to improve immunity and resist cancer." Is this statement true?
Answer: "it's true."
Selenium, a trace element, plays an important role in human body. Selenium can stimulate the immune globulin in the body, make it produce antibodies and improve the immune function of the human body.
If the body has enough immunoglobulin antibodies, immunity will continue to strengthen, and the ability to resist the outside world will also be improved, thereby reducing the risk of disease.
Do you think selenium only has the function of "improving immunity"? No, its function is far more than this one.
Selenium supplementation can also play a certain anti-cancer effect. There are thousands of ways to fight cancer. How does selenium fight cancer? Let's have a look.
When talking about cancer, it is inevitable to mention carcinogens, such as heavy metals, chemicals, radiation, smoke, etc. In this industrialized era, we are inevitably exposed to some carcinogens in our daily life, so reducing the probability of carcinogens inducing cancer is the top priority.
Selenium happens to have this function. Sufficient selenium in the body can reduce the damage caused by heavy metals, radiation and other carcinogens to the body, reduce its toxicity and carcinogenicity, and reduce the risk of cancer after the body is stimulated by carcinogens.
In addition, many cancer patients are also loyal fans of selenium. During the period of cancer, the two most difficult treatments are radiotherapy and chemotherapy.
Although radiotherapy and chemotherapy can destroy cancer cells in the body, they can also cause damage to normal cells in the human body. Therefore, to some extent, they belong to a treatment method of "injuring 1000 enemies and damaging 500 self". Many patients may suffer from depression and hair loss after radiotherapy and chemotherapy.
Selenium supplementation can also enhance the tolerance of cancer patients to radiotherapy and chemotherapy, and improve the discomfort symptoms after treatment.
It is precisely because selenium has this powerful function that many people call it the "king of cancer". Although this title is a little exaggerated, it also confirms the position of selenium in the hearts of cancer-fighting people.
What are the benefits of selenium supplementation, in addition to improving immunity and anti-cancer? Let's get to know each one.
2、 What are the benefits of selenium supplementation?
When it comes to the king of health preservation, selenium is indispensable, not only because selenium can improve immunity and cancer, but also for other reasons, such as oxidation resistance, cardiovascular protection, etc.
If there is enough selenium in the human body, it can improve the antioxidant performance of the body and reduce the damage of oxidation to the body.
When it comes to oxidative damage, people may not understand it. For example, if you cut an apple and put it in the air for a long time, the color of the apple will soon turn yellow, black and begin to rot. this is the damage of oxidation to the apple.
In other words, oxidation will also cause the same damage to the human body, which will lead to accelerated aging of the human body and wrinkles in the skin. Therefore, antioxidation is an important factor to enhance immunity and delay aging.
If you want to improve the antioxidant function of the human body, you should supplement enough selenium to reduce the damage of oxidation to the body, delay the aging speed of the body, and promote the elimination of free radicals in the body.
For beauty lovers, enough selenium can also improve skin elasticity, reduce wrinkles and make skin younger.
Secondly, selenium supplementation also has protective effects on the cardiovascular system, such as promoting the decline of blood pressure, reducing blood consistency, reducing cholesterol content, etc., and preventing hyperlipidemia, hyperlipidemia, hypercholesterolemia and other diseases.
Seeing this, some people may wonder, how can selenium have such powerful functions? It can prevent so many cardiovascular diseases.
In fact, the culprit of most cardiovascular diseases is free radicals, and selenium is the natural enemy of free radicals. Enough selenium can effectively remove harmful free radicals in the body, reduce the damage of free radicals to blood vessels, delay the aging speed of blood vessel walls, and thus prevent a variety of cardiovascular diseases.
If selenium is insufficient in the body, it will lead to the continuous damage of the blood vessel wall by free radicals, which will accelerate the aging speed of the blood vessel wall, reduce its elasticity and become fragile. In this case, once stimulated by the outside world, the vascular wall is prone to rupture, bleeding and other symptoms, inducing thrombosis, cerebral hemorrhage and other diseases.
Therefore, if patients suffer from coronary heart disease, hypertension, myocardial infarction and other cardiovascular diseases, it is suggested that patients should supplement selenium more, promote the elimination of harmful free radicals, repair and soften blood vessels, which is beneficial to the recovery of cardiovascular diseases.
Since selenium has so many benefits, what foods should we eat to supplement selenium?
3、 What food can you eat to supplement selenium?
Diet regimen, pay attention to is: correct diet, adequate supplement.
Correct diet refers to precise attack on which nutrient elements need to be supplemented. For example, people who want to supplement selenium can eat more egg foods such as goose eggs, quail eggs, duck eggs and eggs; Cashew nuts, melon seeds, almonds and other nut foods; Pig liver, pig kidney, goose liver and other animal liver foods.
Secondly, you should also eat more shrimp, sea cucumber, oyster, lobster and other aquatic products; Kidney beans, soybeans, black beans, red beans, soymilk and other bean products. In addition, papaya, apples, cabbage, green vegetables, spinach, radish and other vegetables and fruits are also rich in selenium.
After mastering the correct diet, you need to pay attention to appropriate supplementation. Any nutrient should be "appropriate". If you supplement it too much, it will backfire.
Generally, it is enough to supplement about 50ug selenium every day, and it is not appropriate to overdose it. If you blindly supplement selenium, it will have a negative impact on the body, such as chronic selenium poisoning.
Selenium poisoning patients may have discomfort symptoms such as limb numbness, dizziness, no appetite for food, low spirits, dull skin pain, hair loss, nail deformation, papules on the skin surface, skin pruritus and so on. Therefore, it is recommended to supplement an appropriate amount of selenium, not too much.
