2. Good for health

A. You can enjoy pasta on any budget, and you can have a different and delicious low-cost meal every day of the week. Just serve it with a different sauce. It’s easy to make a healthy meal in minutes that will satisfy your whole family. Pasta tastes good and it's healthy. It also has a long shelf life, so you can keep it in the kitchen cupboard until you need to cook a meal.

B. It's rather difficult to find out where pasta comes from. Archeologists believe that cooking noodles was already quite a common practice in Arabic countries in the 5th century AD. At the same time, the Chinese were also making a noodle-like food. The way it reached Europe is still a mystery, though there are many theories – some believe that travelling Arabs from Central Asia were responsible for bringing early forms of pasta to the West.

C. Despite its reputation, pasta is a low-calorie dish which is good for you. With only 200 calories per cup and a gram of fat, it is perfect even for those on a strict diet. Pasta is naturally packed with vitamins and necessary minerals so it is heart-healthy as well. Pasta may help people to control their blood sugar and weight so it is recommended as part of a well-balanced diet.

D. It seems that pasta was first introduced to Italy in the eighth century. Its ‘home’ was the southern island of Sicily. Prior to its wide use in the 13th century, pasta was considered to be a luxury product in Italy. The reason was that it took a lot of time to make it as all the work was done by hand. By 1400, pasta was sold in shops, but at night a guard was kept to protect the high-priced goods.

E. Only in the 16th century did pasta become popular and affordable to all classes of people. In the city of Naples a machine was made that allowed huge quantities of pasta to be produced. It turned pasta into a cheap food. The number of pasta shops in Naples grew to three hundred. From Naples pasta began to conquer the rest of the country.

F. By the 17th century, machine-made pasta had become part of the daily meal among both rich and poor. Pasta was sold as street food by people called maccaronaros, who cooked it over an open fire. It was eaten on the spot with bare hands, with no sauce. The wealthy, who did not eat with their hands, preferred fresh pasta with cheeses and meat. With the introduction of the fork, pasta began to be served at special occasions all over Italy.

G. When most people talk about pasta, they usually think of Italy and its cooking traditions. The country and its dish have become synonymous. When Italians immigrated to different countries all over the world, they took their pasta with them to each area that they inhabited along with other customs and habits and thus pasta has become the world's favourite food.
