Selenium is an essential mineral that plays a key role in supporting the body's antioxidant defenses and maintaining overall health. While selenium is found in a variety of foods, certain groups of people may be at a higher risk of selenium deficiency, including:

People with poor dietary intake: Individuals with a diet low in selenium-rich foods (such as Brazil nuts, seafood, meats, and whole grains) may be at risk.

Those with digestive disorders: Conditions like Crohn’s disease, celiac disease, or irritable bowel syndrome (IBS) can affect nutrient absorption, including selenium.

People undergoing certain treatments: Individuals undergoing dialysis or certain cancer treatments may have an increased need for selenium.

Pregnant and breastfeeding women: Increased nutritional demands during pregnancy and breastfeeding may make it harder to meet selenium requirements through diet alone.

Individuals with a history of alcohol use: Excessive alcohol consumption can impact nutrient absorption and lead to a deficiency in selenium and other essential nutrients.

People with compromised immune systems: Those with weakened immune systems, such as those with HIV/AIDS, may be at risk for a selenium deficiency.

Ensuring adequate selenium intake through diet or supplementation is important for maintaining overall health and supporting the body's natural defense systems.
