Recently, an Italian expert's research shows that people who often eat pizza have a lower probability of suffering from pharyngeal cancer than ordinary people by 34% and a lower probability of suffering from esophageal cancer by 59%. The traditional Italian pizza is used in the study: it has a thin skin, a lot of tomato sauce and some cheese. Researchers believe that pizza cheese is a kind of dairy product, which is made of concentrated and fermented milk. It basically excludes a lot of water in milk and retains the essence with high nutritional value, which is known as "gold" in dairy products. Every kilogram of cheese products contains 10 kg of milk, including protein, calcium, phosphorus and other nutrients needed by human body. The unique fermentation process makes the absorption rate of protein reach 96% ~ 98%.

Cheese can enhance human body's disease resistance, promote metabolism, enhance vitality, protect eye health and keep skin healthy. Lactic acid bacteria and its metabolites in cheese have a certain health care effect on human body, which is conducive to maintaining the stability and balance of normal intestinal flora and preventing constipation and diarrhea. Because people in China are not used to eating cheese directly, pizza is a way to eat cheese. For pregnant women, middle-aged and elderly people, and vigorous young children, cheese is one of the best calcium supplements. But eating too much cheese can lead to weight gain. At present, low-fat cheese pizza is very popular in American pizza shops. Low-fat cheese pizza can not only retain the nutrients of ordinary cheese, but also make people who eat cheese worry-free.
