The new dishes provide customers with the opportunity to enjoy pizzas free from artificial preservatives, colours and flavours. Scott Bergren, Pizza Hut president, explained: "With the availability of real, all-natural ingredients, Pizza Hut is redefining quality in the pizza category. We've always been known for our great tasting pizzas and adding all-natural ingredients takes our commitment one step further." The chain conducted its own research and found that 73% agreed that foods that are natural have flavour the way it was meant to taste. While testing the product, customers showed a strong preference toward all-natural ingredients in the markets. Pizza Hut's new ingredients include all-natural sauce from vine-ripened tomatoes with no high-fructose corn syrup; all-natural pepperoni with no artificial preservatives, no nitrites or nitrates added; all-natural Italian sausage with no artificial colors, flavours or preservatives; and 100% real beef with no fillers. The new ingredients are presented in red Pizza Hut pizza boxes made from 40% recycled materials. The company's migration towards real ingredients began in 2008 when it introduced The Natural(TM), a pizza with all-natural ingredients, for a limited time in select markets. Pizza Hut has almost 6,200 restaurants in the United States and more than 4,000 restaurants in 100 other countries.
