Top Food Sources of Selenium ✓
Function: Antioxidant, thyroid function
(a Chalcogen)
Selenium is a trace mineral essential for antioxidant defense, thyroid hormone metabolism, and immune system function. It helps protect cells from oxidative damage and supports overall health.
Powerful Antioxidant Role – Selenium is a key component of glutathione peroxidase, an enzyme that protects cells from free radical damage.
Supports Thyroid Function – Works closely with iodine to regulate thyroid hormone production and metabolism.
Enhances Immune System – Selenium boosts immune response, helping the body fight infections and inflammation.
May Reduce Risk of Certain Cancers – Some studies link adequate selenium intake to lower risks of prostate, lung, and colorectal cancers.
Critical for Reproductive Health – Essential for sperm motility and overall fertility in men and women.
Found in Soil and Affected by Geography – Selenium content in food varies depending on soil selenium levels, leading to regional differences in intake.
Deficiency Can Cause Keshan Disease – A rare heart condition seen in selenium-deficient areas, emphasizing the mineral’s importance.
Excess Intake Can Be Toxic – High selenium consumption may cause selenosis, with symptoms like hair loss, gastrointestinal upset, and nerve damage.
Supports Cognitive Health – Some evidence suggests selenium may protect against cognitive decline and support brain function.
Stored in Body Tissues – Selenium is stored primarily in the liver, kidneys, and muscle tissues for later use.
