The benefits of the trace element selenium on the body!

Trace element selenium is an essential nutrient for the human body. It plays an important role in several physiological processes, including immune system function and thyroid hormone metabolism. Selenium is also known for its antioxidant properties and pro rad to neut cells from oxidative stress.

One of the main functions of selenium in the body is as a component of glutathione peroxidases (GPx), which are enzymes that neutralize hydrogen peroxide and organic hydroperoxides produced during metabolism. These enzymes are important for preventing selenium oxidatives damage to cell Also a component of a different family of enzymes called thioredoxin reductases (TrxRs), which also help protect cells against oxidative stress.

Another important function of selenium is its role in the metabolism of thyroid hormones. Selenium is required for the activity of the enzyme iodothyronine deiodinase, which converts the inactive form of thyroid hormone (T4) to the active form (T3).

Selenium is also believed to play a role in cancer prevention. Several observational studies have found an association between higher selenium levels and a lower risk of certain types of cancer, including prostate cancer and breast cancer.

Selenium can be obtained from food sources such as seafood, nuts, seeds, and whole grains. Brazil nuts are particularly high in selenium. The daily recommended intake for adults is 55 micrograms per day. However, please note that Selenium levels can vary dep the geographic location, soil and so on. It's always important to consult with a healthcare professional before taking any supplement.

There are several benefits of getting enough selenium from your diet or supplements. Some of the main benefits include:

1. Supporting immune system function: Selenium plays a role in the activation and proliferation of certain immune cells, which can help to improve overall immune system function.
2. Antioxidant protection: Selenium acts as an antioxidant by neutralizing harmful free radicals and protecting cells from oxidative stress. This can help to reduce the risk of chronic diseases such as cancer and heart disease.
3. Thyroid function: Selenium is essential for the proper metabolism of thyroid hormones, which regulates metabolism and energy levels.
4. Cancer prevention: Some research suggests that higher selenium levels may be associated with a lower risk of certain types of cancer, such as prostate cancer and breast cancer.
5. Cardiovascular health: Selenium may help to reduce the risk of cardiovascular disease by improving the elasticity of blood vessels and reducing inflammation.
6. Cognitive function: Some studies have also suggested that selenium may have a role in cognitive function, although more research is needed to confirm this.

It is important to note that selenium levels from food sources can vary depending on the geographic location, soil and agricultural practices, so it's important to consult with a healthcare professional for advice about selenium intake.

The recommended daily intake of selenium varies depending on different sources and guidelines. However, generally speaking, the recommended intake for adult is:

55 micrograms per day for adult men and women in the United States.

100-150 micrograms per day for adult men and women in China.

150 micrograms per day for adult men and women in Europe.

It's important to note that these are general recommendations and that individual needs may vary depending on factors such as age, sex, pregnancy, lactation, and overall health. Also, pregnant or lactating women may require higher levels of selenium, and people with certain health Conditions may also require higher or lower levels.

It's also important to note that getting too much selenium can be harmful as well, which can cause symptoms such as hair loss, nail brittleness, diarrhea, skin rash, and anemia. It is also toxic in large doses. The upper limit for selenium is 400 micrograms a day for adults.

It is always recommended to consult with a healthcare professional before taking any selenium supplements, especially if you are pregnant, breastfeeding, have any medical conditions, or are taking any medications.

Selenium is a trace mineral that can be found in certain foods. Some of the best food sources of selenium include:

• Seafood: seafood such as oysters, crab, lobster, and shrimp are all rich in selenium. Tuna, sardines and cod also contain selenium.
• Nuts and seeds: Brazil nuts, sunflower seeds, and sesame seeds are all high in selenium.
• Meats and poultry: meats and poultry like beef, chicken, pork and turkey also contain selenium.
• Whole grains: Whole grains such as brown rice, oats, and barley contain selenium.
• Dairy: Milk and cheese also contains selenium.

It's important to note that the selenium content of food depends on the selenium content of the soil where the food was grown. Foods from countries or regions with low soil selenium content will have lower selenium contents.

It's also important to note that cooking or processing foods can affect the selenium content. For example, selenium can be lost during food processing such as milling, or refining. So, it is always good to consume the food in their natural form as much as possible.

It's always important to have a balanced diet that includes a variety of foods to meet your daily nutritional needs, including selenium. If you have any concerns about your selenium intake or are at risk of deficiency, it's best to speak with a healthcare professional advice.
