Imagine that your dear family has just undergone an operation, or perhaps yourself, lying in a hospital bed, facing the long road ahead. At this time, you hear the doctor and the people around you emphasize over and over again: "If you have surgery or are sick, you should eat some good supplements." But in the midst of all this advice and information, do you really understand what "nutrition" really is? We often hear about the need to supplement with protein, vitamins, minerals, etc., but what are the specific effects of these nutrients on recovery? Why is proper nutrition more important than usual when the body is vulnerable? 
Nutrition, in short, is the substance that the body needs to survive, grow, maintain a healthy state and perform its daily functions. It includes five broad categories: proteins, carbohydrates, fats, vitamins, and minerals, each of which plays an integral role. Protein: The main building block of the body, not only as a building block of muscles and tissues, but also as a key component in repairing injuries (such as recovery after surgery) and producing important biochemicals (such as enzymes and hormones). Carbohydrates: The primary source of energy** that supports daily physiological activities and the body's recovery process. Complex carbohydrates, such as whole grains, provide more consistent energy than simple carbohydrates, such as sugar. Fats: Another important source of energy and essential for maintaining cell structure, absorbing certain vitamins, and producing essential fatty acids. Vitamins and minerals: While they are not required in large quantities by the body, they play a central role in maintaining bodily functions, strengthening the immune system, bone health, and cell repair. After surgery and during illness, the body's repair mechanisms kick in, and the demand for nutrients increases. Protein helps repair damaged tissues, carbohydrates provide the energy needed for recovery, fat supports long-term energy needs and cellular recovery, and vitamins and minerals ensure that it all runs smoothly. Deficiencies in any of these nutrients can delay the recovery process, increase the risk of infection, and even affect the overall effectiveness. Practical advice: Scientifically supplement a nutritionally balanced diet: Ensure a balanced intake of the five major categories of nutrients, especially increasing the proportion of high-quality protein (e.g., lean meats, legumes) and complex carbohydrates (e.g., whole grains). Personalized Nutrition Plan: A personalized nutrition supplement plan is developed by a medical professional, taking into account the type of surgery, the individual's health status, and specific needs. Stay hydrated: Adequate hydration is essential to promote nutrient absorption and cell repair. 
1. Enhance immunity: The importance of proteinDuring surgery and disease recovery, the repair mechanism in the body is accelerated, and protein becomes an indispensable nutrient. Protein is not only the basis for cell regeneration, but also enhances the function of the immune system and aids in wound healing. Can be diversified to include fish, meat, eggs, and legumes. The focus is on adequate intake while focusing on the quality of the protein. 2. Promote wound healing: Vitamin C and zinc vitamin C are essential for enhancing the repair of blood vessels, bones and soft tissues. At the same time, it is a powerful antioxidant that can reduce the damage caused by free radicals and speed up the recovery process. Citrus fruits and green leafy vegetables are good for vitamin C**. Zinc is another mineral that is essential for wound healing, it is involved in cell** and protein synthesis and is key to the proper functioning of the immune system. Meats, nuts, and whole grains are good for zinc**. 3. Maintain energy and weight: During the recovery period of healthy carbohydrates, it is important to maintain proper energy intake, which can provide stable energy**. The complex carbohydrates found in whole grains, fruits and vegetables, and legumes provide fiber, vitamins, and minerals in addition to energy to support overall health. 
4. Maintain fluid balance: Proper water intake is essential to maintain fluid balance after surgery and during recovery from illness. In addition to drinking water directly, water-containing foods such as fruits and soups are also a great way to stay hydrated. Electrolytes, such as sodium and potassium, play a key role in regulating water balance and neuromuscular function in the body. A reasonable diet should include good ** of these elements, such as bananas (good for potassium**) and a moderate amount of salt (** of sodium**) Fifth, adjust fat intake: choose high-quality fats, especially unsaturated fatty acids, such as omega-3 and omega-6, which are beneficial to reducing inflammation and promoting cardiovascular and cerebrovascular health. Deep-sea fish, flaxseeds, and nuts are all good for this type of healthy fat**.
