Inevitably, some recipes need more of a makeover than others. Such was the case with this soup, which had 555 calories and 38.2 grams of fat per serving. After eliminating more than a quarter-pound of butter and substituting reduced-fat products for the whole milk and full-fat cheeses, the final result was an equally savory dish with 329 calories and 10.8 grams of fat per serving. You can improve the health benefits of your own soups at home by starting with fat-free, low-sodium broths and using reduced-fat dairy products.
