- Selenium is a mineral that keeps your body healthy by fighting cell damage, helping the thyroid gland work well, and being good for making babies. It can even be helpful for people with asthma and might stop cancer from starting.
- You can find selenium in foods like Brazil nuts, seafood, meat, eggs, and whole grains. Adults should try to get 55 micrograms every day to stay healthy.
- Taking too much selenium can make you feel sick or cause hair loss. Always talk to a doctor before taking selenium pills to make sure you’re not having too much.
What is Selenium?
Selenium is a trace mineral your body needs in small amounts. It plays an important role in many bodily processes. This mineral is a part of proteins called selenoproteins, which are essential for DNA synthesis, protection from infection and oxidative damage, and thyroid hormone metabolism.
Your body can’t make selenium on its own. You need to get it from foods or sometimes supplements. Good sources include Brazil nuts, fish, eggs, and grains that grow in selenium-rich soil.
Eating the right amount of selenium helps keep your immune system and thyroid working well. It’s also key for reproductive health and may protect against some diseases like heart problems and certain types of cancer.
Possible Health Benefits
Selenium offers various potential health benefits, including protecting against cell damage, supporting thyroid health, promoting reproductive health, potentially helping with asthma management, and offering protection against certain types of cancer.
These benefits highlight the importance of maintaining adequate selenium levels in our diet for overall well-being.
Protects against cell damage
Our bodies face a daily battle with tiny invaders called free radicals. These troublemakers can harm our cells, leading to health problems over time. But there’s good news! Selenium acts like a superhero, guarding our cells from these attacks.
This mineral works as an antioxidant, which means it fights off the bad effects of free radicals.
Eating foods high in selenium helps keep your body’s defense strong. You can think of antioxidants as bodyguards for your cells—they help keep everything safe and sound inside so you stay healthy on the outside.
It’s one way to ensure you take care of yourself at the smallest level—your amazing cells!
Supports thyroid health
Selenium helps your thyroid work well. The thyroid gland needs this mineral to make hormones that control how fast your body uses energy. Enough selenium keeps the thyroid healthy to do its job right.
If you don’t get enough, you might have trouble with your thyroid.
People eat foods rich in selenium for a strong thyroid. Doctors say this nutrient lets the thyroid make and use its hormones correctly. Good hormone levels mean better health for your whole body, not just the neck area where your thyroid sits.
Promotes reproductive health
Selenium plays a crucial role in promoting reproductive health. This essential mineral supports the growth and healthy muscle activity vital for reproductive organs. For women, selenium supplementation has shown promise to enhance reproductive health and function in cases of deficiency.
Also, selenium protects cells from damage, indirectly benefiting overall reproductive health.
Selenium also plays an important role in supporting fertility and reproduction in men. Adequate selenium levels help maintain healthy sperm production and motility, contributing to male reproductive health.
May help with asthma
Research suggests that selenium supplementation may offer relief for individuals dealing with asthma. Studies have indicated that people with chronic asthma might have lower selenium levels than those without the condition.
Observational research has also revealed a potential association between low selenium levels and asthma severity. Additionally, evidence shows that individuals with asthma may exhibit low blood levels of selenium.
Furthermore, studies have proposed that selenium supplementation could aid in managing asthma symptoms by potentially reducing their severity.
May protect against cancer
Selenium may help protect against cancer by supporting the immune system and acting as an antioxidant, protecting cells from damage. Studies have suggested that selenium’s role in reducing oxidative stress and inflammation could lower the risk of certain cancers.
Selenium’s ability to regulate DNA repair and cell growth also supports its potential in preventing cancer development.
Research has shown that higher levels of selenium in the body may be associated with a decreased risk of certain cancers, including prostate, lung, colorectal, and bladder cancers.
However, it’s important to note that while selenium shows promise in cancer prevention, further research is needed to understand its specific effects on different types of cancer fully.
Food Sources and Recommended Intake
Selenium is present in a variety of foods, and the recommended daily allowance for adults is 55 micrograms. Here are some good food sources of selenium and their respective selenium content:
- Brazil nuts: Known for having exceptionally high selenium content, with just two nuts providing over 100% of the recommended daily intake.
- Seafood (oysters, tuna, halibut, sardines): Rich sources of selenium.
- Meat (beef, liver, lamb): Provides significant amounts of selenium.
- Poultry (chicken, turkey): Contains selenium within favorable quantities.
- Eggs: A good source of selenium.
- Whole grains: Such as wheat germ and brown rice.
Risks and Side Effects
Excessive intake of selenium can lead to toxicity, which may cause symptoms such as nausea, vomiting, and hair loss. To learn more about selenium’s risks and side effects, keep reading for valuable information on maintaining a healthy balance.
Risks of deficiency
Selenium deficiency can lead to health issues, especially in regions with low selenium levels in the soil. Groups at risk for deficiency include people with gastrointestinal disorders, HIV, and those undergoing kidney dialysis.
Deficiency symptoms may include fatigue, hair loss, weakened immune function, and infertility.
Furthermore, research suggests a potential link between low selenium levels and certain types of cancer. To mitigate these risks, consuming selenium-rich foods such as Brazil nuts, sunflower seeds, fish, and eggs is essential, or considering selenium supplements if advised by a healthcare professional.
The dangers of excess intake
Consuming too much selenium can lead to health issues. Excessive intake may cause muscle tremors, hair loss, stomach upset, and lightheadedness. High levels of selenium in the body over a long time can result in toxicity and various health problems.
Moreover, taking selenium with medications that slow blood clotting might increase the risk of bruising and bleeding.
It’s important to be mindful of your selenium intake. Chronically high levels could have adverse effects on your health. Therefore, it’s crucial to stick to the recommended daily amount and avoid excessive consumption of selenium for overall well-being.
Use of selenium supplements
Consider consulting a healthcare professional before starting selenium supplements. Excessive intake of these supplements may lead to side effects and risks, so it’s important to be cautious about the dosage.
Selenium supplements are often promoted for benefits like boosting immune function and supporting a healthy reproductive system. However, weighing the potential risks against the advantages is crucial when considering their use.
Remember that proper guidance from a healthcare provider is essential when incorporating selenium supplements into your health regimen. Always prioritize safety and be well-informed about these supplements’ possible risks and benefits before making any decisions regarding their usage.
