Who hasn't enjoyed eating peanuts? Did you know that although peanuts look like nuts and taste like nuts,
they aren't nuts at all? They belong to the pea family, so they are called peanuts.
     The peanut grows flowers above ground, but its "fruit" grows underground. It grows in more countries
than most other "nuts". The peanut is a native South American plant. Scientists believe that it grew wild in Brazil
long ago. They think that for several thousand years the early peoples of South America made it a part of their
diet. These peoples were nomads who moved on when a natural food could no longer be found in one area.
Along the way they probably let fall some peanuts, which got into the ground and grew. This is believed to be
the way the plant reached the place where the Incas (印加人) lived. The Incas, from about 1100 to 1532,
thought highly of peanuts.
      The peanuts were eaten in several forms and used as sacrificial offerings (祭品) to. the Incan Sun God.
Later in the 16th century, European soldiers had brought peanuts to other parts of the world, including North
America, Africa, Asia, Europe, and Pacific Islands.  
     Although peanuts were found native in South America, they are now grown in almost every country that
has warm weather. India produces the most peanuts. China's production is next, followed by the United States.
     The peanut is special in more ways than one. It can be eaten raw, boiled, roasted, or fried. Hundreds of
widely different products have been made from it. Carver, an American scientist, set himself the task of
discovering new uses for eating peanuts and many other products.
     Peanuts are very highly nutritious and are also high in protein (蛋白质). Americans use about seven-tenths
of their protein in the form of meat. In India, where the poor can't pay for meat or milk, peanut meal and peanut milk have been produced. These have been a great help to the poor.
     New products are continually being made from peanuts, among them peanut cheese and a powder that
becomes peanut butter when water is added. The fact is that peanuts are so healthy that they are used by
astronauts. The unusual nut that isn't a nut is one of nature's most amazing gifts.
