Key Takeaways

  • Selenium is a mineral your body needs for good health. It helps protect against damage from free radicals, keeps your thyroid working properly, and supports your immune system.
  • Not having enough selenium can cause hair loss, make you feel weak or tired, lower how well you fight off sicknesses, hurt how well you think and remember things, and mess up your thyroid’s work.
  • If the soil where food grows doesn’t have much selenium or someone has health problems like Crohn’s disease that make it hard to take in nutrients from food, they might not get enough of this important mineral. People with HIV or those who are on kidney dialysis also need to watch out for low selenium levels.
  • Eating foods like nuts, seafood, meat, and eggs or taking a supplement can help fix low levels of selenium, but be careful not to get too much because it can harm your body.
  • Talk to doctors about the right amount of selenium for you, especially if you live in an area with less selenium in the ground or if you have certain illnesses that could lead to a deficiency.

What is Selenium?

Selenium is a trace mineral your body needs to stay healthy. It plays a key role in metabolism and thyroid function, helping to produce thyroid hormones. This mineral acts like an antioxidant, which means it fights damage from harmful particles called free radicals.

Your brain and immune system also need selenium to work their best.

You don’t need much selenium; small amounts keep you in good shape. Foods like nuts, seafood, meat, eggs, and some grains are great sources of selenium. Soil has selenium, too, so the food can vary depending on where it’s grown or raised.

Causes of Selenium Deficiency

Selenium deficiency can occur due to limited intake or absorption of selenium, living in regions with low soil selenium content, undergoing kidney dialysis, and living with HIV. These factors can contribute to a decreased supply of this essential mineral in the body, leading to potential health issues.

Limited intake or absorption

Your body needs a little selenium every day to stay healthy. If you don’t get enough from your food, you might have problems like weak muscles and hair falling out. Some people don’t eat enough foods that are high in selenium.

Others may eat enough, but their bodies can’t take it in well. This could happen if they have a health problem like Crohn’s disease, making it hard for their gut to absorb nutrients.

Eating foods with more selenium, like nuts, meat, and fish, can help. If you also get enough vitamin E from things like nuts and green veggies, it helps your body use the selenium better.

But be careful not to eat too much because it’s possible to get too much selenium, which can cause other health issues.

Living in selenium-deficient regions

People living in places where the soil has low levels of selenium face a bigger risk of not getting enough. The amount of selenium in foods can depend greatly on how much is in the soil where plants grow or where animals graze.

If you eat mostly foods from an area with little selenium, your body might not get what it needs for strong health.
