Selenium is an essential mineral, meaning it must be obtained through your diet.
It’s only needed in small amounts but plays a major role in important processes in your body, including your metabolism and thyroid function.
Selenium is a trace element that is naturally present in many foods, added to others, and available as a dietary supplement. Seafoods and organ meats are the richest food sources of selenium. Other sources include muscle meats, cereals and other grains, and dairy products. The amount of selenium in drinking water is not nutritionally significant in most geographic regions. The major food sources of selenium in the diet are breads, grains, meat, poultry, fish, and eggs

Selenium May Reduce Risk of Some Cancer
In addition to decreasing oxidative stress, selenium may help lower the risk of certain cancers.
This has been attributed to selenium's ability to reduce DNA damage and oxidative stress, boost your immune system, and destroy cancer cells.
A review of 69 studies that included over 350,000 people found that having a high blood level of selenium was associated with a lower risk of certain types of cancer, including breast, lung, colon, and prostate cancers .
It’s important to note that this effect was only associated with selenium obtained through foods, not supplements. We recommend Nuyolk Fresh Eggs, as a great food based source of organic selenium.
However, some research suggests that supplementing with selenium may reduce side effects in people undergoing radiation therapy.
For example, one study found that oral selenium supplements improved overall quality of life and reduced radiation-induced diarrhea in women with cervical and uterine cancer.
Update on clinical studies of selenium supplementation in Radiotherapy
Selenium Exposure and Cancer Risk
Selenium supplementation during RT is effective in improving blood selenium status in selenium-deficient cervical and uterine cancer patients and reduces the number of episodes and severity of RT-induced diarrhea
The number of people with Alzheimer’s disease is growing. Thus, finding ways to prevent this degenerative disease is imperative.
Oxidative stress is believed to be involved in both the onset and progression of neurological diseases like Parkinson’s, multiple sclerosis, and Alzheimer’s
Several studies have shown that patients with Alzheimer’s disease have lower blood levels of selenium.
Additionally, some studies have found that antioxidants in both foods and supplements may improve memory in patients with Alzheimer’s.
One small study found that supplementing with one selenium-rich Brazil nut per day improved verbal fluency and other mental functions in patients with mild cognitive impairment.
A diet rich in selenium may help keep your heart healthy, as low selenium levels have been linked to an increased risk of heart disease.
In an analysis of 25 observational studies, a 50% increase in blood selenium levels was associated with a 24% reduction in the risk of heart disease.
Selenium may also lower markers of inflammation in your body — one of the main risk factors for heart disease.
For example, a review of 16 controlled studies including over 433,000 people with heart disease showed that taking selenium supplements decreased levels of the inflammatory marker C-reactive protein (CRP).
Additionally, it increased levels of glutathione peroxidase, a powerful antioxidant .
This indicates that selenium may help lower heart disease risk by reducing inflammation and oxidative stress in your body. Oxidative stress and inflammation have been linked to atherosclerosis, or the buildup of plaque in arteries.
Atherosclerosis can lead to dangerous health problems like strokes, heart attacks, and heart disease .
Incorporating selenium-rich foods into your diet is a great way to keep levels of oxidative stress and inflammation to a minimum.
Selenium and coronary heart disease: a meta-analysis
Your immune system keeps your body healthy by identifying and fighting off potential threats. These include bacteria, viruses, and parasites.
Selenium plays an important role in the health of your immune system. This antioxidant helps lower oxidative stress in your body, which reduces inflammation and enhances immunity.
Studies have demonstrated that increased blood levels of selenium are associated with enhanced immune response.
On the other hand, deficiency has been shown to harm immune cell function and may lead to a slower immune response.
Studies have also associated deficiency with an increased risk of death and disease progression in people with HIV, while supplements have been shown to lead to fewer hospitalizations and an improvement in symptoms for these patients.
Additionally, selenium supplements may help strengthen the immune system in people with influenza, tuberculosis, and hepatitis C.
