Linguine is a type of pasta similar to fettuccine and trenette but elliptical in section rather than flat. It is about 4 millimetres (0.16 in) in width, which is wider than spaghetti but not as wide as fettuccine. The name linguine means "little tongues" in Italian, where it is a plural of the feminine linguina. A thinner version of linguine is called linguettine. Linguine was traditionally served with sauces such as pesto but others such as tomato or fish based sauces are popular as well. Linguine is typically available in both white flour and whole-wheat versions but was originally made with durum wheat. Linguine originated in Italy and is based on more traditional pastas.
Nowadays, most products sold as pasta are made from common wheat. However, similar noodles can be made from other grains, such as rice, barley or buckwheat.
Some types of pasta are refined during processing, stripping the wheat kernel of the bran and germ, removing many of the nutrients.
Sometimes refined pasta is enriched, meaning it has some nutrients, such as B vitamins and iron, added back in.
