Diet plays a crucial role in patient care and recovery. Nurses must understand the importance of a balanced diet that includes a variety of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals. Proper nutrition can accelerate healing, improve the immune system, and enhance overall well-being. Nurses should also be aware of specific dietary needs for different conditions, such as low-sodium diets for hypertension or high-protein diets for wound healing.
