According to the nutrition database given by the USDA, the recommended size for as serving of cheese curds is 1 oz, which is much lower than the 8 oz recommended size for yogurt. When it comes to calories, 8 oz of yoghurt will contain about 150 calories, while an equal sized portion of cheese curds can carry around 830 calories. There is a pretty serious difference when the two foods are compared on a caloric basis and it is clear why a much smaller serving of cheese curds are recommended on a daily basis by the USDA.
