How can I get the best absorption of selenium?

The main factors that affect the absorption of selenium are as follows:

1. Iron supplementation. Having sufficient iron can improve the utilization rate of selenium. Patients with iron deficiency anemia may also have decreased glutathione peroxidase activity.

In this case, selenium supplementation should be accompanied by iron supplementation to restore glutathione peroxidase activity to normal levels in a timely manner.

2. Bacterial infection.

Intestinal microbial interference. Escherichia coli, Streptococcus faecalis, Clostridium and some Salmonella can combine the body's selenium into its own enzymes to use amino acids instead of sulfur-containing amino acids, and can also convert the soluble form of selenium into an insoluble form, so that it cannot be absorbed by the human body. Therefore, the interference of gut bacteria should be taken into account when determining the recommended amount of selenium in the diet.

3. Lack of vitamin E

Vitamin E reduces the body's consumption of selenium. Vitamin E and selenium have their own independent effects in metabolism, and they also complement each other. Adequate vitamin E can improve the body's ability to utilize selenium, and the amount of selenium in the liver can be multiplied.

4. Other aspects.

Different forms of selenium have different utilization rates. In addition to the organic form of selenium-containing amino acids (such as selenomethionine, selenocysteine, etc.), selenium in human food also exists in inorganic forms and in the form of polysaccharides combined with other organic chelates. These different forms of selenium enter the human body and are used to different degrees.

Compared with inorganic selenium, organic selenium has a higher utilization rate. Organic selenium mainly includes selenium yeast, selenium-rich foods (selenium malt powder, selenium-rich edible fungus powder) and so on.

Selenium protein is best absorbed by the body. Protein selenium is a natural organic selenium, which can be efficiently absorbed by our body and can be consumed for a long time. Now the more popular selenium supplement food - rice embryo selenium, the selenium contained in it is organic protein selenium.

Legume. Stir-fried white pumpkin seeds, soybeans, red kidney beans, broad beans, mung beans, safflower beans, tiger skin kidney beans, flower peas, peanut kernels, northern tofu, southern tofu.

Fruits and vegetables. The highest content of vegetables is golden cauliflower, camellia, garlic, mushrooms, followed by peas, Chinese cabbage, pumpkin, radish, leeks, onions, tomatoes, lettuce, etc. Eating more fruits, vegetables and other foods rich in vitamins A, C, and E can help with selenium absorption.

In fact, foods rich in selenium are also rich in vitamin E, and these two nutrients interact with each other.

Eggs. Eggs contain micrograms of selenium, duck eggs contain micrograms of selenium, and goose eggs contain micrograms of selenium.

Aquatic products. Mackerel (mackerel), prawns, dace, large yellow croaker, herring, Chinese horseshoe crab, shrimp skin, red ladyfish, mackerel (mackerel), hairtail, sea bass, river prawns, moray eel, bighead carp (fathead), marsh prawn, carp, grass turtle.

Meat. Beef kidney, pork kidney, chicken breast, pork (lean), duck liver, chicken liver, lamb (lean).

The effect of dietary therapy is not obvious, and it is important to persist. It is recommended to take some selenium supplements, selenium-rich and the like.

The role of selenium: Selenium is called the "king of anti-cancer" among the trace elements in the human body by scientists Scientific research has found that the level of blood selenium is closely related to the occurrence of cancer. A large number of surveys have shown that the level of selenium in food and soil in an area is directly related to the incidence of cancer, such as:

The high levels of selenium in the food and soil in this region are associated with low cancer incidence and mortality, and conversely, the high incidence and mortality of cancer in this region show that selenium is closely related to the occurrence of cancer. At the same time, the scientific community has also recognized that selenium is the "king of anti-cancer" among the trace elements in the human body. Boosts immunity:

Organic selenium can scavenge free radicals in the body, eliminate toxins in the body, antioxidant, can effectively inhibit the production of lipid peroxide, prevent blood clots, remove cholesterol, and enhance human immune function. Prevent diabetes: Selenium is the active ingredient that makes up glutathione peroxidase, which can prevent the oxidative destruction of pancreatic islet cells, make them function normally, promote sugar metabolism, reduce blood sugar and urine sugar, and improve the symptoms of diabetic patients.

Cataract prevention: Selenium can protect the retina, enhance the finish of the vitreous, improve vision, and have the effect of preventing cataracts. Prevention of cardiovascular and cerebrovascular diseases:

Selenium is an important element for maintaining the normal function of the heart, and has a protective and repairing effect on the heart muscle. The decrease in blood selenium level in the human body will lead to the decrease of the function of scavenging free radicals in the body, resulting in an increase in the deposition of harmful substances, an increase in blood pressure, a thickening of the blood vessel wall, a decrease in the elasticity of blood vessels, a slowdown in blood flow, and a decrease in oxygen delivery function, thereby inducing an increase in the incidence of cardiovascular and cerebrovascular diseases. Prevent Keshan disease, large bone joint disease, arthritis:

Selenium deficiency is the main cause of Keshan disease, large bone joint disease, and two endemic diseases, selenium supplementation can prevent bone marrow end lesions, promote repair, and promote disulfide bonds in protein synthesis against metal element detoxification. It has a good preventive and ** effect on patients with these two endemic diseases and arthritis. Detoxification, detoxification:

Selenium binds strongly to metals and can resist cadmium poisoning to the kidneys, gonads and central nervous system. Selenium combines with heavy metals such as mercury, tin, thallium, and lead in the body to form a metalselenoprotein complex for detoxification and detoxification. Prevention and treatment of liver disease, protection of the liver:

After 16 years of epidemiological investigation in areas with a high incidence of liver cancer, Yu Shuyu, a medical expert in China, found that the selenium content in the blood of residents in areas with high incidence of liver cancer was lower than that in areas with low incidence of liver cancer, and the incidence of liver cancer was negatively correlated with blood selenium level. Bengbu Xiweikang Biotechnology Co., Ltd., based on the standards of the National Health Organization, has developed selenium-rich rice and tea, with an organic selenium content of 100-300 micrograms per kilogram, which has successfully opened up a safe and effective new channel for human selenium deficiency food supplements.

Eat more foods that contain a lot of selenium.

Which foods are high in selenium?

Although butter, fish meal, lobster, mushrooms, pork kidney, garlic and other foods contain a certain amount of selenium, the absorption rate is not ideal. Nutritionists advocate supplementation of organic selenium, such as selenate polysaccharides, selenium yeast, selenium eggs, selenium-rich mushrooms, selenium-rich malt, selenium-rich gastrodia, selenium-rich tea, selenium-rich rice, etc.

Selenium intake is more related to the selenium content of the soil than to dietary patterns. Soils in the United States and Canada appear to contain enough selenium. A study of vegetarians and vegans in the United States found that they consumed enough selenium.

Selenium is found in many foods, but it's especially found in brazil nuts, whole grains (whole wheat bread, oatmeal, barley), white rice, and legumes.

Eggs contain more selenium than meat, and per 100 grams of food, pork contains micrograms of selenium, eggs contain micrograms of selenium, duck eggs contain micrograms of selenium, goose eggs contain micrograms of selenium, ginseng contains 15 micrograms of selenium, and peanuts contain micrograms of selenium. For example, the selenium content of grain produced in China's high selenium areas is as high as 4 8 milligrams per kilogram, while the grain in low selenium areas is milligrams per kilogram, a difference of 1000 times.

There are three ways to supplement selenium, the first way is to supplement selenium with drugs, the second way is to supplement with food, and the third way is to supplement with selenium by improving lifestyle.

First of all, pharmaceutical selenium supplementation can take yeast selenium and protein selenium preparations to supplement the deficiency of trace element selenium in the body.

Secondly, because selenium is an antioxidant that can effectively resist oxidation and prevent cancer, it is also rich in selenium in some foods. It is recommended to eat more of these foods when supplementing with selenium, such as eggs, lean meat, garlic, corn, shrimp, oysters, etc.

Finally, lifestyle improvements can also be made, such as going to bed early, waking up early, increasing the duration of deep sleep, not staying up late, and getting in the sun every day can also help selenium be digested and utilized in the body.

Top 10 Best Foods to Eat to Protect Your Liver, What Foods to Eat.

The seafood, edible mushrooms, meat, etc. we eat daily actually have selenium, but the content of selenium is not very high. It is best to directly buy selenium-rich foods from big brands to help the human body replenish selenium, such as the brand of selenium Huinong, which specializes in R&D and sales of selenium-rich products, and the product quality is guaranteed

"Selenium is a trace element necessary for the human body, selenium deficiency can easily lead to the decline of the body's immunity, so that the metabolism is slow, you must supplement a sufficient amount of selenium every day to maintain the balance of the human body, you can supplement by taking selenium tablets, it is best to take it on an empty stomach to improve the absorption rate of selenium. You can also eat more animal liver, such as duck liver, pig kidney, chicken liver, etc., and you can also eat more seafood, such as fish and shrimp, sea cucumber, oysters, etc., eggs and vegetables are also rich in selenium, such as Chinese cabbage, seaweed, pumpkin, kelp, asparagus, etc. "

Selenium supplementation products to choose the right, to choose organic selenium, inorganic selenium is not easy to be absorbed by the human body and harmful to the human body, in the choice also need to pay attention to screening, now many people directly use the inorganic selenium industrial treatment method for organic synthesis, this residue is more, the conversion rate is low, the effect is also poor, it is best to choose pure natural malt selenium, which is made by absorbing selenium elements when the wheat sprouts, directly drying and pressing the malt after the tablet, the conversion rate is high, and the organic selenium content reaches more than 97%, such as the brand of Weixunkang.
