There are about 5000 types of potatoes around the world, and in Peru, where I am from, exist about 3000 types. The potato was introduced to humanity during the Neolithic Era / The Revolution of Agriculture,  3000 - 2000 B.C.E  years ago. The potato was a very important source of food for the people who lived in the Andes region. These people learned different techniques to grow and store it.  Nowadays the potato is big part of our Peruvian culture. In Peru and in other places around the world there are Potato International Centers (CIP) where they keep making scientific investigations to learn more of the benefits of its consumption. On May 30th of every year we celebrate  the "Day of the potato" in Peru, where through expositions, fairs and other events, people can try the different varieties of potatoes, which are used in different Peruvian dishes.
