United Dairy Farmers, or UDF, was founded in 1940, when Carl Lindner Sr. opened the first UDF store in Cincinnati. UDF introduced its frozen yogurt along with reduced-calorie ice cream in 1989. As of 2010, UDF offers five flavors of frozen yogurt, with slightly varying nutritional components. UDF frozen yogurt is low in calories, but it may not necessarily be a good dietary choice, especially if you are on a low-carbohydrate diet.
Calorie Content
The calorie content for UDF yogurt varies by flavor. A 1/2 cup serving of the milk chocolate, strawberry and vanilla flavors provides 120 calories, while the cherry cordial and "cookies & cream" flavors contain 150. All of the flavors are lower in calories than a 1/2 cup of ice cream, which contains about 170 calories per serving.
Fat Content
Like most frozen yogurt, UDF frozen yogurt is relatively low in fat. The cherry cordial flavor is highest of the five flavors, with 4.5 g per 1/2 cup serving, while the strawberry flavor is lowest, with 1.5 g per 1/2 cup serving. The amount of saturated fat in UDF frozen yogurt ranges from 2.5 g in the cherry cordial flavor to 1 g in the strawberry flavor.
Carbohydrate Content
UDF frozen yogurt is rich in carbohydrates. The cookies & cream flavor contains the most carbohydrates, with 25 g per 1/2 cup; vanilla contains the least, with 21 g per 1/2 cup. Most of the carbohydrates come from sugar. Vanilla and milk chocolate have the lowest levels of sugar, with 17 g per 1/2 cup, while the cherry cordial has the most, 20 g of sugar per 1/2 cup.
Protein Content
UDF frozen yogurt is not a rich source of protein. Although most flavors have 4 g of protein per 1/2 cup, the milk chocolate flavor provides 5 g, and the strawberry contains 3 g per 1/2 cup. Many other dairy products are higher in protein, such as cottage cheese, which contains 16 g of protein per 1/2 cup.
Vitamin and Mineral Content
One 1/2-cup serving of UDF frozen yogurt is not a rich source of many vitamins and minerals, but every flavor offers 15 percent of the daily recommended intake of calcium, 2 percent of the daily recommended intake of vitamin A and between 2 and 15 percent of the vitamin C recommended intake. The cookies & cream and cherry cordial flavors provide 2 percent of the recommended intake of iron, although no other flavors provide any of this nutrient.
