Believe it or not, pizza-long an American food staple-has been losing popularity since 2000.A major contributor to the decline is America's growing interest in health.Those who fear carbohydrates don't want the crust,those who fear fat don't want the cheese, the oils, or the high-fat meats.So what is the pizza community doing to quell these fears and revive America's interest in pizza? Many prizzerias are moving away from fancy ingredient and large-sized pizzas and returning to the basic-focusing on quality ingrediants rather than unique, abundant toppings. On the other hand,a few of the larger chains are trying out new-concept pizza. Overall, the pizza industry is working hard to entice the pizza lover back.
