Do you know the importance of selenium to the body? Doctor: It is important to the human body in three aspects.

Calcium, iron, zinc, selenium, vitamins and so on. Are essential nutrients in our daily diet. They can not only provide enough nutrition and energy for the normal operation of our bodies, but also promote the growth and development of our bodies and make them healthier. Then do you know its importance to our human body?

As one of the 15 essential nutrients in our daily diet, selenium is an indispensable trace element in our body. At the same time, it is also one of the important components of selenoprotein, which plays a very important role in human body. In addition, selenium also has a good antioxidant effect, which plays a very important role in maintaining the function of thyroid gland and DNA synthesis in our body, as well as maintaining the normal immune system. Doctor's tip: Selenium is very important to the human body, and its importance to the human body mainly includes these three points.

1. Against free radicals

In fact, the process of energy conversion in our body is very complicated. In this complicated process, we not only have to continuously inhale oxygen to oxidize the carbohydrates in the food we eat, so as to produce the energy, carbon dioxide and water we need, but also produce a substance with free oxidation groups in this process, which is what we often call "free radicals". However, the oxygen contained in this free radical is very unstable, which may oxidize the surrounding cells at any time, causing damage to cell membranes and cells, and eventually leading to inflammation, arterial injury and even cancer. Therefore, if we ingest a proper amount of selenium in our life, it can combine with free radicals, thus eliminating the activity of free radicals, playing a role in fighting free radicals and reducing the risk of physical illness.

2. Reduce the risk of cancer

In addition to fighting free radicals, selenium can also help reduce the risk of certain cancers in the body. Studies have found that selenium can help the body reduce DNA damage and oxidative stress, but it can enhance the immune system's ability to destroy cancer cells. Thereby well inhibiting the growth of cancer cells and reducing the risk of cancer.

3. Promote thyroid health

Iodine plays a very important role in enhancing our thyroid function. In fact, selenium is also very important for maintaining thyroid function. According to the research, if the level of selenium in human blood decreases, it will cause autoimmune thyroiditis and hypothyroidism. Therefore, proper intake of selenium in life can effectively promote thyroid health.
