Vietnamese cuisine often employs low-fat cooking methods such as steaming, boiling, grilling, or stir-frying with minimal oil. Sour soup, a traditional dish made from fish and vegetables like tomatoes, pineapple, tamarind, and bean sprouts, is not only refreshing but also rich in nutrients. This dish helps balance the digestive system, supplements vitamins and minerals, and preserves the natural flavors of the ingredients.
