==Special Precautions of Brazil nuts==

*Brazil nuts are high in [[selenium]] and an ounce (roughly half a dozen) provides 800 micrograms. That's about double the US recommended tolerable upper limit. Overindulging regularly could lead to selenium toxicity. Symptoms may include a metallic taste, garlic odor on the breath, hair loss, brittle nails, fatigue, nausea, rash, diarrhea, runny nose, cough and nerve pain. Selenium-containing supplements are another potential source of this mineral.

* Rich in [[Methionine]].

==The benefits of Brazil nuts are==

*High [[Selenium]] Content : The greatest health benefit of Brazil nuts lies in their high selenium content, and this is what makes them so special. One single kernel provides 100% of the daily value for selenium, while 1 ounce contains as much as 536.8 mg of this nutrient, meaning 766% of the DV! The body cannot produce selenium by itself, so it must be obtained through food and water. Although not being an antioxidant, selenium plays an important role in the antioxidant defense system of the human body. It boosts the activity of antioxidants, for their functionality greatly depends on the presence of selenium. Selenium is an essential component of two important antioxidant enzymes, known as glutathione peroxidise and thioredoxin reductase, and it also increases the vitamin E function in the body. High levels of selenium in Brazil nuts are therefore associated with many health benefits. Listed below are some of the most important ones.
