A Brief History of Pizza: The Dish that Conquered the World

Pizza, the way we know it today, is a derivation from focaccia (from the Latin word for fire), flat bread that has been prepared since antiquity in different forms and garnished with herbs, olives, fat, raisin, honey, and nuts.

The word pizza in Italian identifies any type of flat bread or pie—fried or baked. Although you’d find many types of pitas or pizzas around the Mediterranean, it is in Naples that pizza in the form we know it today first emerged, after the tomato appeared on the table in the 1700s. Naples has many records of pizza since around the year 1000; the first mentions call these flat breads laganae, and later they are referred to as picea. In those times, pizzas were dressed with garlic and olive oil, or cheese and anchovies, or small local fish. They were baked on the open fire and sometimes were closed in two, as a book, to form a calzone.

In Naples is also where the first pizzerias opened up, with brick wood-burning oven, covered with lava stones from the Mount Vesuvius. The chefs of those times ignored pizza because was considered a poor people’s food, but the new combination with the tomato, when it entered the kitchen around the 1770s, must have raised some curiosity, even in the royal palace. Ferdinand I Bourbon, King of Naples, loved the simple food of the people and went to taste the pizzas made in the shop of Antonio Testa. He liked it so much that he wanted pizza to be included in the menu at the court. He failed after the opposition of his wife, Queen Maria Carolina. His son Ferdinand II also liked all kind of popular food and he loved pizza to the point that he hired Domenico Testa, son of the now famous Antonio, to build a pizza oven in the royal palace of Capodimonte.

Pizza became very popular, earning its place in Neapolitan folklore. Simple and economical, it turned into the food for all people, even sold on the streets, as shown in many illustrations of the time.

A famous episode extended the popularity of pizza beyond the limits of the city of Naples. It was 1889, and Margherita, queen of Italy, was visiting the city. She was told about pizza and wanted to taste it. A famous cook by the name of Don Raffaele, helped by his wife Donna Rosa, was invited to cook pizza at the royal palace. They prepared three pizzas, typical of that time: one with cheese and basil; one with garlic, oil, and tomato; and one with mozzarella, basil, and tomato. The queen, impressed by the colors of the last pizza, which resembled the national flag, preferred that one. Since then this pizza is known as Pizza Margherita, and Don Raffaele is credited with its invention, even if we know that it already existed for a long time.

At the beginning of the last century, with Italian immigrants, the first pizzerias appeared also in the United States, where pizza has become a mass phenomenon. Yet, even today the best pizza is found in Naples, where it is rigorously made with buffalo mozzarella. Superior pizzas are considered those obtained by moderate variations of the simplest and most popular: Pizza Napoletana with tomato, garlic, oil, and oregano; Pizza Margherita; Pizza Marinara with tomato, anchovies, capers, and olives; and Pizza Four Seasons, divided in four quadrants, each dressed in a different way. Pizza with hot salami, the American pepperoni pizza, is instead found in the Calabria region south of Naples, where this type of hot sausage is produced.

4000 Year Old Secrets of Green Tea

The Chinese have known about the medicinal benefits of green tea for over 4,000 years. But recent studies are just starting to unlock these ancient secrets of green tea.

Today, a great deal of research is being carried out about green tea health benefits and the findings are very exciting.

Here are just a few medical conditions that drinking green tea is reputed to be helpful with:

  • Cancer
  • Rheumatoid arthritis
  • High cholesterol levels
  • Cardiovascular disease
  • Infection
  • Impaired immune function
  • Controlling high blood pressure
  • Lowering blood sugar

Researchers believe the real secret of green tea lies in the fact that it is rich in EGCG which is a powerful anti-oxidant. EGCG has been found to kill cancer cells without harming healthy tissue.

A University of Purdue study recently concluded that a compound in green tea actually inhibits the growth of cancer cells.

Red wine has been long studied because it contains resveratrol, a polyphenol that limits the negative effects of smoking and a fatty diet.

But researchers from the University of Kansas determined that EGCG is twice as powerful as resveratrol, which may explain why the rate of heart disease among Japanese and French men is quite low, even though approximately seventy-five percent of them are smokers.


Research also indicates that drinking green tea lowers total cholesterol levels, as well as improving the ratio of good (HDL) cholesterol to bad (LDL) cholesterol.


But the health benefits of green tea don't end there. Green tea has been found to inhibit the abnormal formation of blood clots which is the leading cause of heart attacks and stroke.


New studies have actually shown that green tea can even help you loose weight. The American Journal of Clinical Nutrition performed a study at the University of Geneva in Switzerland. Researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or a placebo.

It has also been shown that drinking green tea can give your body a greater ability to fight infection and kill bacteria.

Green tea can even help prevent tooth decay. Its bacteria-destroying abilities kill the bacteria that causes dental plaque and aids the immune system with its antifungal properties by improving digestive function.

You may be asking if other Chinese teas offer similar health benefits. But the answer is no. Although green, oolong, and black teas all come from the leaves of the Camellia sinensis plant, the way green tea is processed is what sets them apart.

Green tea leaves are steamed, and that prevents the EGCG compound from being oxidized. Black and oolong tea leaves are made from fermented leaves, which converts the EGCG into other compounds. This process makes oolong and black teas much less effective in preventing and fighting various diseases.

So how much green tea should you drink? There are as many answers to this question as there are researchers investigating the health properties of green tea.

While some companies selling green tea say that ten cups per day are necessary to reap the maximum benefits, a University of California study on the cancer-preventative qualities of green tea concluded that you could probably attain the desired level of polyphenols by drinking two cups a day.

The research of this ancient beverage continues, and it may take decades to unlock all of the secrets it holds. Although green tea should not be considered to be a magic bullet, researchers agree the positive health benefits are very promising.
