Vitamins, proteins, potassium, and many other essential nutrients are often mentioned when we discuss essential nutrients. However, there are still tons of vitamins that don’t get enough attention. In fact, people always forget that the term essential nutrients refer to a variety of vitamins and minerals rather than just a few.

Certain “essential” nutrients are often taken for granted as we only need a minimum amount of them. One of these is selenium — ever heard of it? 

In this blog, we will be talking about the benefits of selenium in our body and how it affects our everyday body functions.

What is Selenium?

The benefits of selenium in our body are much more unique compared to the common nutrient we hear about. But before we discuss its benefits, let us first talk about what selenium is.

Selenium is naturally occuring mineral on certain plants like wheatgrass, alfalfa and barley

Selenium is a trace mineral found in water, soil, and some plants. Although it is not needed in huge amounts, the body requires it to get energized and to function normally. Furthermore, this mineral regulates our metabolism and thyroid, which makes it even more important. 

Here are some of the health benefits of selenium:

1. It helps to nourish your thyroid glands.

Selenium is an important component for the health and nourishment of your thyroid glands. It helps to regulate the secretion of thyroid hormones, and it stimulates the production of T3 hormone which is the most active form of thyroid hormone in the body.

Your thyroid glands perform a very important role in the body. It is important for the regulation of the metabolism of the body cells.

Proper regulation of the thyroid is very crucial to our health as it affects the speed of our metabolism. Too much or even too little can impact the way our body functions.

For instance, when too much thyroid glands are secreted you may risk having hyperthyroidism. This condition could cause your body cells to work faster than it normally should. Oftentimes, people with hyperthyroidism may experience a faster heart rate or frequent diarrhea.

On the other hand, fewer thyroid glands may lead to a condition called hypothyroidism. Essentially, this may lead to slower metabolism making you feel constipated and, in some cases, gain weight.

2. It helps to reduce the risk of joint inflammation.

Joint inflammation can happen to anyone, regardless of their age. Having this medical condition can hinder your everyday work due to constant pain or swelling.

Typically, joint inflammation happens when damaged tissue or our immune system produces chemicals that can cause swelling in the joint. To some, they experience inflammation due to arthritis, a chronic condition. Other times, it may be caused by external factors such as an injury. 

One effective way to prevent joint inflammation is through selenium.

Selenium’s important function includes working to reduce oxidative stress around the joints. This will result in a reduced risk of inflammation. Selenium deficiency is one of the contributing causes of rheumatoid arthritis and the deterioration of joint tissues.

Other ways to prevent joint inflammation

Making a few changes in your lifestyle can take time. But as you slowly get used to it, you will start to realize that it brings wonders to health.

Aside from selenium, there are also several healthy habits that can help you lower the risk of experiencing inflammation. Among these includes:

  • Have a healthy diet. What you eat affects the functions of your body. With that in mind, you want to ensure that you eat foods that will provide the sufficient nutrients that you need.
  • Don’t drink alcohol or smoke. If you want to feel the full benefits of your efforts to work out and maintain a balanced diet, skip your unhealthy habits.

3. It helps to prevent cancer.

Selenium are important in DNA repair to fight cancer cells

According to a study, they found that selenium may play an active part in preventing cancer by supporting DNA repair and synthesis in damaged cells. This can help to prevent the growth of cancer cells.

Moreover, selenium might also play a role in inducing cancer cells to self-destruct. This process is called apoptosis. The body uses it as a self-destruct mechanism to eliminate abnormal cells.
