COMPARED WITH ICE CREAM and traditional (supermarket) frozen yogurt, the brands I looked at do offer some nutritional benefits. They are lower in calories and fat. (The froyos generally have 100-150 calories and no fat per half-cup serving, compared with 250-300 calories and 5-10 grams of fat for ice cream.) The yogurts offer the advantage of probiotics, the healthy bacteria we rely on for digestive and immune functions.

However, frozen yogurts are still high in sugar, and the amount varies considerably — from 20 grams in a half-cup serving in the more basic flavors to 52 grams in others.
