"I heard that selenium is good for fighting cancer and enhancing immunity, but how do we usually supplement selenium?" At a recent family gathering, Aunt Li suddenly raised this question.
As the head of the family, she has always attached great importance to the nutritional balance of her family, but the concept of selenium is still a little foreign to her. Everyone exchanged words and words, hoping to find scientific answers.
Selenium has the reputation of "anti-cancer element", and the World Health Organization has listed it as one of the essential trace elements in the 21st century. So, what exactly are its benefits to the human body? How can we add to this? Let's break down the answers one by one.
One of the main effects of selenium is to enhance the body's antioxidant capacity and immune function. It is the main component of glutathione peroxidase, which effectively removes peroxide from the body and prevents DNA damage from producing cancerous cells.
At the same time, selenium can also enhance the body's resistance to viral infections, and it is also of great value in the prevention of some influenza infections. Therefore, selenium supplementation is not only beneficial for cancer prevention, but also for overall physical fitness.
Secondly, selenium is also an important mineral needed to maintain the growth and development of the human body. It is directly involved in the body's protein synthesis, and selenium deficiency can cause problems such as malnutrition and skin ulcers. Therefore, pregnant women, infants and other special populations should pay more attention to the supplement of selenium.
In addition, selenium can also promote insulin production, which is beneficial for lowering blood sugar and preventing diabetes. In terms of cardiovascular, appropriate amount of selenium supplementation can also prevent atherosclerosis and reduce the risk of cardiovascular and cerebrovascular diseases.
So, how to reasonably supplement this important trace element in daily life? Let's start with food and recommend several ingredients with high selenium content:
The first high-selenium food is nuts. For example, almonds, walnuts and cashew nuts can provide an average of about 50-100 micrograms of selenium per 100 grams, which can be called the "king of selenium". Foods such as mushrooms, seafood, and rice koji are also good sources of selenium.
The second is edible mushrooms rich in plant selenium. Taking the common shiitake mushrooms and Xiuzhen mushrooms as examples, the average selenium content per 100 grams exceeds 20 micrograms, which is a good food supplement for selenium.
The third food is nightshade vegetables. For example, tomatoes and green peppers are rich in organic selenium, and regular consumption can play a role in long-term selenium supplementation. The most common thing we Chinese residents eat is selenium-rich rice, so eating more staple foods is also conducive to selenium supplementation.
In addition, animal foods such as animal liver, lean meat, poultry eggs, etc. are also excellent sources of selenium. Therefore, in the daily diet, a balanced combination of the above types of ingredients is very helpful to achieve a reasonable intake of selenium.
Of course, for special groups with severe risk of selenium deficiency, such as severe patients such as cancer or people who exercise vigorously, selenium preparations can also be appropriately supplemented under the guidance of doctors to meet the higher needs of the body.
But doctors have also repeatedly stressed that any nutrient intake must be measured. Although selenium is an essential trace element, excessive intake can also produce toxic reactions, the most common manifestations are: nausea and vomiting, diarrhea, rash, etc., and even damage liver and kidney function in severe cases.
Therefore, for the general population, as long as you pay attention to a balanced diet every day, it is enough to supplement from food in moderation, and you must not blindly take selenium preparations in large doses.
In short, the importance of selenium to the body cannot be underestimated, and we should all pay attention to it. Housewives like Aunt Li take the initiative to pay attention to health knowledge, and in the future, they should continue to strengthen the nutritional ratio of their families, reasonably supplement selenium and other beneficial elements, and escort the health of the whole family.
