The Brazil nut, also known as Bertholletia excelsa, is a natural wonder of the Amazon rainforest. Cherished by the indigenous people of this region for its much-needed protein, fats and other essential nutrients, this nut has, in recent years, become widely recognized as an herbal supplement. In the local region where it is found, some of the common names for this nut are castania, castanha-do-pará, para-nut, Castaña-de-Brazil and cream-nut. Contrary to popular belief, Brazil nuts are found in many areas other than Brazil. Such areas include Bolivia, Columbia, Peru, Venezuela and the Guianas. In fact, it is Bolivia, not Brazil, who is the largest producer of Brazil nuts.
Almost exclusively, Brazil nut trees can be found in abundance in non-flooded forest regions of South America. This stately tree is one of the largest trees in the Amazon rainforest, growing up to 50 meters tall and living anywhere from 500 to 700 years.

Each fruit pod contains 12 to 25 Brazil nuts, which is the part of the tree that people use for a variety of health and culinary purposes.

A Brazil nut consists of 70 percent fat and 17 percent protein. However, most of these fats are "good fats" like mono-unsaturated fatty acids such as palmitoleic acid and oleic acid. These types of fats help to lower "bad cholesterol" and increase "good cholesterol" in your body. Research studies show that diets rich in palmitoleic acid and oleic acid help to prevent coronary artery disease and strokes.
Brazil nuts have also been found to contain high amounts of vitamin-E. On average, 100 grams of these nuts contains a whopping 52 percent of the recommended daily value of Vitamin E.
