Read the passage.

People have been eating yogurt as a staple health food item for many years. In the 1970s, the popularity of ice cream was rising and so was freezing and production technology. This technology initiated the idea of frozen yogurt as a dessert. Frozen yogurt launched into the market in the 1970s, with hope of a success. However, frozen yogurt was a complete failure due to the taste. Many customers complained that the flavor of frozen yogurt tasted too much like regular yogurt. Therefore, the demand of frozen yogurt slowed at a shocking rate in the 1990s. It was clear that frozen yogurt needed to change its flavor to appeal to more people. If not, frozen yogurt would not exist.

In the 2000s, trends changed. All of a sudden, there was demand for frozen yogurt as an alternative to unhealthy desserts, like ice cream or gelato. This is because yogurt is well known to be a great source of calcium and have a low fat content. In comparison, traditional ice cream was a very sweet dessert with a high fat content. This healthier aspect of frozen yogurt lead to a tripled economic growth rate. Due to the increase in popularity, there is now a wide variety of flavors to choose from. Healthier options include strawberry, peach, banana, or raspberry. Unhealthier options include chocolate, cookie, or baked good flavors. Additionally, it is now served in a variety of ways, like soft serve and hard serve, and can be served in either a cup or a cone.
