Briefly explain dietary sources, deficiency, toxicity, and recommended intake of selenium
Good sources of selenium include Brazil nuts, meat (especially organ meat), and fish. Severe selenium deficiency results in Keshan disease, a potentially fatal disease that causes serious heart problems and mostly affects children. Keshan disease was first documented in the Keshan region of China, which has very low levels of selenium in its soil. Consuming high amounts of selenium can result in nausea, vomiting, diarrhea, and brittleness of the teeth and fingernails. Selenium's Recommended Dietary Allowance is 55 ?g/day, and its Tolerable Upper Intake Level is 400 ?g/day.
