The brazil nut tree is native to the Amazon region of South America, where it is one of the tallest trees in the rainforest. The tasty nuts the tree bears are botanically not nuts at all, but seeds.
Brazil nuts are high in calories and high in fat, but most of this is healthy monounsaturated fat such as oleic acid, which is known to help boost "good" cholesterol while lowering "bad" cholesterol.
Vitamin E is also found in brazil nuts, and acts as a powerful antioxidant in the body, helping to protect us from the cell damage caused by free radicals; it's also a great boost to the skin.
Brazil nuts are also very rich in selenium, being one of the best if not the best natural source for this important nutrient. Selenium is necessary for thyroid health, good cognitive function, a healthy immune system and for fertility in both men and women.
Brazil nuts are also good sources of B vitamins such as thiamin, riboflavin and niacin, which are all important for a healthy metabolism. Other vital minerals such as copper, magnesium and manganese are also to be found in brazil nuts.
