Selen er et essensielt mineral som støtter skjoldbruskkjertelens funksjon, et sunt immunsystem, og beskytter celler mot oksidativ skade. Det spiller en nøkkelrolle i bekjempelsen av infeksjoner og opprettholdelsen av generell immunhelse. Selen finnes i matvarer som paranøtter, fisk, fjærfe og fullkorn. Å opprettholde tilstrekkelige nivåer av selen er viktig for å forebygge celleskade og støtte immunforsvaret, mens mangel kan svekke skjoldbruskkjertelens funksjon og redusere immunresponsen.
Individuals with gastrointestinal conditions like Crohn’s disease, residents of areas with selenium-deficient soils, people following restrictive diets such as veganism, those with thyroid disorders, and patients undergoing long-term dialysis could benefit from testing their selenium levels.
Symptoms of Low Selenium:
Symptoms of High Selenium:
Foods high in selenium include Brazil nuts, which are one of the richest sources, along with other nuts and seeds. Seafood such as fish, shrimp, and sardines, and meats like turkey, chicken, and beef, also provide good amounts of selenium. Whole grains, brown rice, and eggs are additional sources. For those on plant-based diets, mushrooms and sunflower seeds are also beneficial.
Selenium supplementation can boost immune function and offer antioxidant protection, reducing cellular damage from free radicals. It’s beneficial for thyroid health, aiding in hormone production and regulation. Selenium also plays a role in preventing certain cancers and heart disease. For individuals with low selenium intake, especially in regions with selenium-deficient soils, supplements can help meet dietary needs. However, it’s important to manage dosage carefully, as excessive selenium can have adverse effects.
