Selenium

Why Does a Selenium Deficiency Occur?

Selenium deficiency typically arises due to inadequate dietary intake. This can happen in regions where soil has low selenium levels, affecting crops and livestock. Certain health conditions, such as gastrointestinal disorders, can impair selenium absorption. Diets lacking in selenium-rich foods like nuts, seafood, and meats also contribute to deficiency. 

Excessive intake of foods that inhibit selenium absorption also play a role, such as grains with high phytic acid like whole grains, legumes, and soy products. Some people may also have genetic factors that influence selenium metabolism, increasing their risk of deficiency.

What to Do About Selenium Deficiency?

Increasing selenium intake through diet is essential. Consuming selenium-rich foods such as Brazil nuts, seafood, eggs, and meats can help. For those with dietary restrictions or absorption issues, selenium supplements may be necessary. Monitoring and adjusting dietary habits to ensure a balanced intake of nutrients can also support overall selenium levels.
