Here are some of the most remarkable benefits of this powerful nutrient.
Selenium acts as a powerful antioxidant
Selenium protects the body’s cells from damage caused by free radicals.
This antioxidant effect may help reduce the risk of chronic diseases such as heart disease and cancer.
Reduces the risk of cancer
According to a review of 69 studies conducted by Zhejiang University in China, high levels of selenium in the blood are associated with a lower risk of cancers such as breast, lung, and colon cancer.
This is partly because selenium helps reduce DNA damage and strengthens the immune system.
Supports heart health
Selenium helps reduce oxidative stress and inflammation, both of which are key factors in the development of heart disease.
A study from Johns Hopkins University found that a 50% increase in blood selenium levels reduced the risk of heart disease by 24%.
Supports cognitive function
Selenium may play a crucial role in preventing neurodegenerative diseases such as Alzheimer’s.
Foods rich in selenium have been shown to improve memory and cognitive function in people with Alzheimer’s.
Essential for thyroid health
The thyroid gland contains more selenium than any other gland in the body.
This mineral is crucial for the production of thyroid hormones and helps prevent diseases such as Hashimoto’s thyroiditis, in which the immune system attacks the thyroid.
Strengthens the immune system
Selenium enhances the body’s ability to fight infections by reducing inflammation.
It helps the immune system function optimally, making the body more resistant to diseases.
May relieve asthma symptoms
Early studies suggest that selenium may reduce lung inflammation and alleviate asthma symptoms.
Although more research is needed, the results so far are promising.
Supports fertility
Selenium plays an important role in fertility, especially in men, as it is essential for the production of healthy and motile sperm.
An adequate selenium level may improve sperm quality and increase the chances of conception.
Protects against premature aging
Thanks to its antioxidant properties, selenium helps combat free radicals that contribute to signs of aging such as wrinkles and skin damage.
A sufficient selenium intake can help maintain youthful skin and promote overall health.
Natural sources of selenium
You can find selenium in foods such as oysters, pecans, tuna, and eggs.
However, the selenium content varies depending on where plants and crops are grown, so it’s beneficial to include a diverse range of foods in your diet.
