Selenium: A Trace Mineral for a Healthy Body
As we grow older, our bodies require a lot of essential minerals and vitamins to function properly. One such mineral is Selenium which plays a vital role in the human body. It is an essential trace element that is important for our overall wellbeing and good health.
Selenium was first discovered in 1817 by Swedish chemist Jöns Jacob Berzelius. In the early days, it was considered as just another toxic element, but later it was found that selenium has several important functions in the human body. It is required only in small amounts but plays an important role in various biological processes.
Benefits of Selenium
1. Helps Protect Against Cancer
Studies have shown that selenium can help reduce the risk of certain cancers including prostate, lung, and colon cancer. It works by reducing DNA damage and oxidative stress caused by free radicals.
2. Boosts Immune System
Selenium helps strengthen the immune system by increasing white blood cells’ production which fights off infections and diseases.
3. Improves Heart Health
Selenium has been linked to improved heart health as it helps lower high blood pressure levels and reduces inflammation throughout the body.
4. Promotes Thyroid Health
The thyroid gland requires selenium to produce hormones that regulate metabolism throughout the body.
5. Increases Fertility
Studies have also suggested that selenium may improve fertility rates among both men and women due to its antioxidant properties.
Sources of Selenium
Although many foods contain some amount of selenium, most people do not get enough from their diet alone.
Some food sources rich in selenium include:
– Brazil nuts
– Tuna fish
– Sunflower seeds
– Eggs
– Brown rice
– Chicken
It’s worth noting that while Brazil nuts are one of the best sources of selenium; they must be consumed carefully due to their high levels of toxicity if over-consumed.
Supplements are another way people can increase their selenium intake. However, it is important to follow recommended dosages as excess amounts of selenium can lead to toxicity.
Selenium Deficiency
A deficiency in Selenium can cause several health problems such as cognitive decline, thyroid dysfunction, and even heart disease. The symptoms of a deficiency include hair loss, muscle weakness, and fatigue.
In some cases, people who are deficient in selenium may develop Keshan disease which is a type of heart disease that affects children in certain regions where the soil is low in selenium.
However, it’s rare for someone to be deficient in Selenium if they eat a balanced diet as most foods contain small amounts of this trace mineral.
Conclusion
In conclusion, Selenium is an essential trace mineral that plays a crucial role in maintaining good health. It has been linked with multiple benefits including cancer prevention and improved heart health among others.
It’s important to consume enough of this nutrient through your diet or supplements but avoid over-consumption as excess amounts can lead to toxicity.
If you’re concerned about your Selenium levels or have any health issues associated with its deficiency; consult your healthcare professional who will recommend appropriate treatment options.
