　　Quinoa can be ground into flour or cooked whole. It is used in cereals, drinks and fresh salads. It can also be mixed with vegetables or beans for a full meal. The leaves and stems can also be used for medicinal purposes. Some people use them to reduce pain, heal wounds and even keep insects away.

　　Quinoa is full of amino acids and minerals. Amino acids are organic compounds that form protein. The body needs them to help break down food, and to grow and repair tissue.

　　The UN Food and Agriculture Organization believes that quinoa can be used to fight hunger and feed a growing world population. The reason is the high value of protein provided by quinoa. The crop has also become popular among those seeking healthier ways to eat. The center of the seed contains up to 45 percent protein.

　　Quinoa is currently grown in more than 70 countries. Peru and Bolivia together produce 92 percent of the crop. The rest comes mainly from the United States, Ecuador, Canada and Argentina.

　　Starting about 10 years ago, the popularity of Quinoa caused its price to rise quickly. Many Bolivian farmers have gained from this increase by earning more. They have been able to buy vehicles and other goods with the increased profits.

　　However, other Bolivians have had to give up their main food because it costs too much. Instead they are buying and cooking with other foods that are not as rich in healthy minerals and proteins.
