A well-balanced diet with selenium-rich foods ensures sufficient intake. Brazil nuts are the most concentrated dietary source, with just one or two nuts providing more than the recommended daily intake. However, due to their exceptionally high selenium content, overconsumption should be avoided to prevent toxicity.
Seafood is another excellent source, particularly fish such as tuna, sardines, halibut, and salmon. These not only supply selenium but also offer omega-3 fatty acids, which contribute to cardiovascular and brain health. Shellfish like shrimp and oysters are also selenium-rich, making them valuable dietary additions.
Meat and poultry provide significant amounts of selenium, with chicken, turkey, and beef being notable sources. Organ meats, such as liver and kidney, contain even higher levels. Dairy products, including milk and eggs, offer moderate amounts, making them good options for those who consume animal-based foods.
For individuals following a plant-based diet, whole grains such as brown rice, barley, and whole wheat are beneficial sources. Selenium content in grains varies depending on soil quality, with some regions producing crops with lower selenium levels. Vegetables such as spinach, mushrooms, and broccoli contribute modest amounts, and legumes like lentils and beans provide additional sources for vegetarians.
Recent research suggests that selenium’s antioxidant properties may help reduce inflammation and oxidative stress, potentially lowering the risk of cardiovascular diseases, neurodegenerative disorders, and certain cancers. It also plays a role in reproductive health, with studies linking adequate selenium levels to improved fertility in both men and women. Additionally, selenium supports the immune response, aiding in protection against infections and viruses, including potential benefits in combating respiratory illnesses.
Ensuring a well-rounded intake of selenium-rich foods can help maintain overall health and prevent deficiencies. By incorporating a variety of these foods into daily meals, individuals can support essential bodily functions and long-term well-being.
