How Many Calories Are in Frozen Yogurt?

Milk fermented with the bacteria lactobacillus bulgaricus and streptococcus thermophilus becomes yogurt. Quality frozen yogurt often contains these microorganisms, which may help improve immune system function, according to the Michigan Dairy Review. Quality frozen yogurt also has sweeteners and flavoring. The yogurt mixture, churned and frozen, becomes soft-serve frozen yogurt.

Calories

A half-cup serving of vanilla soft-serve frozen yogurt contains 114 calories, while a half-cup of chocolate frozen yogurt has 115.

Nutrients

Frozen yogurt contains about 3 g of protein, 4 g of fat and 17 g of carbohydrates. It also has 103 mg of calcium.

Considerations

Frozen yogurt made with heat-treated yogurt and frozen yogurt, in which the fermentation has been skipped altogether, do not contain active cultures. Frozen yogurt containing the "Live and Active Cultures" seal must have at least 10 million organisms per gram at the time of manufacture.
