Limited-edition holiday-inspired yogurts are also new to Safeway-owned stores. Sold in 6-ounce cups, the two low-fat varieties are Cranberry Orange and Pumpkin Pie. There are also two light formulations: Caramel Apple and Gingerbread. The light products start with fat-free yogurt and are sweetened with acesulfame potassium and sucralose in order to keep calories at 80 to 90. The low-fat varieties contain 170 calories.
