Healthy cooking methods that retain nutrients include steaming, grilling, and sautéing. These techniques typically involve shorter cooking times and lower temperatures, minimizing nutrient loss compared to methods like boiling. Steaming, for example, preserves more vitamins and minerals by preventing them from leaching into the cooking water. Additionally, using minimal fats or oils can enhance the healthiness of meals. By choosing these methods, individuals can create dishes that are not only flavorful but also rich in essential nutrients, promoting overall health.
