HN210 Lecture Notes - Lecture 3: Selenium Deficiency, Coeliac Disease, Vitamin K
Document Summary
Selenium is a trace mineral that is essential for human health. It is present in small amounts in various foods, including nuts, meats, and grains. Selenium plays a crucial role in various bodily functions, including immune system function, thyroid hormone metabolism, and dna synthesis. One of the main benefits of selenium is its antioxidant properties. Antioxidants help to protect cells from the damage caused by free radicals, which can lead to inflammation and chronic diseases such as heart disease and cancer. Selenium can also help to boost the immune system, making it easier for the body to fight off infections and diseases. In addition to its antioxidant and immune system benefits, selenium is also important for the metabolism of thyroid hormones. The thyroid gland, located in the neck, produces hormones that regulate metabolism and other important functions in the body. Selenium helps to convert the inactive form of thyroid hormone (t4) into the active form (t3).
