Selenium: A Powerful Antioxidant
First things first, one of selenium’s key jobs in the body is acting as an antioxidant. Antioxidants are substances that protect your cells from damage caused by free radicals, which are unstable molecules that can damage cells and lead to chronic diseases. Think of free radicals like tiny wrecking balls inside your body, and antioxidants like the repair crew coming in to fix the damage.
Selenium is a part of a group of proteins called selenoproteins, which have antioxidant properties. These proteins help neutralize free radicals and prevent oxidative stress, which can contribute to aging, heart disease, and even some types of cancer. So, when you ask, “What does selenium do for the body?” one of the answers is that it protects your cells from the inside out, helping keep you healthier for longer.
Boosting Your Immune System
Another important thing selenium does for the body is support your immune system. A strong immune system is your first line of defense against infections and illnesses, and selenium plays a vital role in keeping it strong. This mineral helps stimulate the production of white blood cells, which are essential for fighting off invaders like bacteria and viruses.
Some studies even suggest that selenium deficiency can weaken immune function, making you more susceptible to infections. If you’ve been feeling run down or catching colds frequently, it could be a sign that you’re not getting enough selenium. So, keeping your selenium levels up is one way to help your immune system stay on its toes.
Selenium and Thyroid Health
Your thyroid is a small but incredibly important gland in your neck that regulates a lot of things, from metabolism to energy levels. Selenium is crucial for thyroid health because it helps convert the thyroid hormone (T4) into its active form (T3). Without selenium, this conversion process can be slower, which can lead to issues like fatigue, weight gain, and even depression.
Low selenium levels have also been linked to thyroid diseases like Hashimoto’s thyroiditis and Graves’ disease, both of which can mess with your thyroid function. By ensuring you get enough selenium, you’re helping your thyroid stay in top shape, which in turn helps keep your metabolism running smoothly.
Selenium and Heart Health
Selenium also plays a role in keeping your heart healthy. Several studies have suggested that this mineral has a protective effect on your cardiovascular system. It helps prevent oxidative stress in blood vessels, which can reduce inflammation and lower the risk of developing heart disease. Some research has even shown that people with higher selenium levels tend to have a lower risk of heart attacks and other cardiovascular problems.
This antioxidant effect is especially important in fighting off the buildup of plaque in arteries (a condition known as atherosclerosis), which can lead to high blood pressure and other serious heart conditions. In short, selenium helps maintain the health of your blood vessels and heart, contributing to overall cardiovascular health.
What Does Selenium Do for Your Skin?
Want better skin? Selenium might be a secret ingredient in your skincare routine, even if you didn’t realize it. Because of its antioxidant properties, selenium helps prevent skin damage from the sun’s harmful UV rays. It also has anti-inflammatory effects, which means it can help calm conditions like acne and eczema.
Moreover, studies have suggested that selenium might help with skin aging. It can help protect the skin from the kind of cellular damage that leads to wrinkles, sagging, and other signs of aging. In other words, getting enough selenium could keep your skin looking healthier and more youthful over time.
How Much Selenium Do You Need?
Now that we know what selenium does for the body, you might be wondering, “How much do I need?” For adults, the recommended daily intake of selenium is around 55 micrograms per day. For pregnant women, that number goes up slightly to 60 micrograms. Keep in mind that selenium can be toxic in large amounts, so it’s important not to overdo it.
The good news is that getting selenium through food is generally safe, and most people get enough just by eating a balanced diet. Foods rich in selenium include:
- Brazil nuts (they are by far the best source!)
- Seafood (like tuna, sardines, and shrimp)
- Meats (especially turkey and chicken)
- Whole grains (such as brown rice and whole wheat bread)
- Eggs and dairy products
For those who don’t eat these foods regularly, selenium supplements are also available. However, it’s always a good idea to talk to a doctor before starting any new supplements, just to be on the safe side.
Can You Have Too Much Selenium?
While selenium is essential for health, too much of it can be dangerous. In fact, selenium toxicity, also known as selenosis, can cause symptoms like nausea, vomiting, hair loss, fatigue, and even nerve damage. The upper limit for selenium intake is about 400 micrograms per day for adults, and exceeding that can lead to problems.
If you’re concerned about your selenium intake, it’s best to consult with a healthcare professional who can test your levels and guide you accordingly.
