Frozen yogurt is a type of dessert that is made from yogurt, which is a fermented milk product. The yogurt is frozen and then served as a cold treat. It can be eaten on its own or topped with various fruits, nuts, syrups, or other sweet ingredients. Frozen yogurt is often considered to be a healthier alternative to ice cream because it typically contains less fat and fewer calories than traditional ice cream. However, the nutritional content of frozen yogurt can vary depending on the brand and flavor.
