What's Delicious Pizza

Pizza is an oven-baked, flat, disc-shaped bread typically topped with a tomato sauce, cheese and various toppings.Originating in Italy, from the Neapolitan cuisine, the dish has become popular in many parts of the world. An establishment that makes and sells pizzas is called a "pizzeria". Pizza is one of the national foods of Italy and the Italian people.

Base and baking methods
The bottom of the pizza, called the "crust", may vary widely according to style—thin as in a typical hand-tossed pizza or Roman pizza, or thick as in a typical pan pizza or Chicago-style pizza. It is traditionally plain, but may also be seasoned with garlic, or herbs, or stuffed with cheese.

In restaurants, pizza can be baked in an oven with stone bricks above the heat source, an electric deck oven, a conveyor belt oven or, in the case of more expensive restaurants, a wood- or coal-fired brick oven. On deck ovens, the pizza can be slid into the oven on a long paddle, called a peel, and baked directly on the hot bricks or baked on a screen (a round metal grate, typically aluminum). When made at home, it can be baked on a pizza stone in a regular oven to reproduce the effect of a brick oven. Another option is grilled pizza, in which the crust is baked directly on a barbecue grill. Greek pizza, like Chicago-style pizza, is baked in a pan rather than directly on the bricks of the pizza oven.

Health issues

Pizza can be high in salt, fat and calories. There are concerns about negative health effects.Food chains, such as Pizza Hut, have come under criticism for the high salt content of some of their meals, which were found to contain more than twice the daily recommended amount of salt for an adult.

European nutrition research on the eating habits of people with cancer of the mouth, oesophagus, throat or colon showed those who ate pizza at least once a week had less chance of developing cancer. Dr Silvano Gallus, of the Mario Negri Institute for Pharmaceutical Research in Milan, attributed it to lycopene, an antioxidant chemical in tomatoes, which is thought to offer some protection against cancer.Carlo La Vecchia, a Milan-based epidemiologist said, "Pizza could simply be indicative of a lifestyle and food habits, in other words the Italian version of a Mediterranean diet." A traditional Mediterranean diet is rich in olive oil, fiber, vegetables, fruit, flour, and freshly cooked food. In contrast to the traditional Italian pizza used in the research, popular pizza varieties in many parts of the world are often loaded with high fat cheeses and fatty meats, a high intake of which can contribute to obesity, itself a risk factor for cancer.
