In the difficult battle against tumors, there is a hidden enemy that silently invades the physical and mental health of patients – and that is malnutrition. A staggering figure shows that up to 80% of cancer patients experience malnutrition in the process, which not only weakens their ability to fight the disease, but also may shorten valuable survival. Imagine if there was a way to effectively replenish these essential nutrients, would we be able to offer a silver lining to these patients? 
The problem of malnutrition of cancer patients is like a killer, secretly eroding the vitality of patients. The reasons behind this are varied, but in the final analysis, they can be divided into two main categories: direct and indirect. Direct factors: The disease itself affects the huge growth demand of tumors, which often "rob" the patient of nutrients, resulting in nutrient insufficiency. At the same time, the abnormal metabolism of tumor cells can also interfere with the normal absorption and utilization of nutrients, forming a "metabolic trap", so that even if the patient eats normally, the nutritional status may deteriorate day by day. Indirect factors: Chemotherapy and radiotherapy, although they are powerful in defeating tumors, are also accompanied by nausea, vomiting, stomatitis, etc., which seriously affect the patient's appetite and food intake. In addition, psychological stressors such as anxiety and depression often lead to a lack of interest in food, and inadequate nutrient intake becomes the norm. Malnutrition: Malnutrition, the enemy that weakens resistance, not only affects the quality of daily life of cancer patients, but is more likely to be a key factor affecting the effectiveness and survival. Below, we take a closer look at its impact from two aspects. A double whammy to the immune systemFirst of all, adequate nutrition is the cornerstone of maintaining the normal functioning of the immune system. Malnutrition directly leads to reduced immune cell function, making patients more susceptible to infections while weakening the natural lethality to tumor cells. Secondly, malnutrition can also affect wound healing and tissue repair, which undoubtedly increases the difficulty and risk of postoperative recovery for patients undergoing surgery**. Hindrance to the effect of chemotherapy and radiotherapy has high requirements for the nutritional status of patients. In malnourished patients, the internal environment may not be conducive to the effective effect of the drug, resulting in poor results. What's more, malnutrition may also affect the patient's tolerance, making it difficult for the patient to complete the plan, which in turn affects the consistency and final results. In the face of cancer, which is the enemy of life, malnutrition is undoubtedly an obstacle that patients must pay attention to and overcome. Through scientific nutritional intervention and lifestyle adjustment, the nutritional status of patients can be effectively improved, the body's ability to resist diseases can be enhanced, and a solid backing can be provided for overcoming diseases. The joint efforts of the patient, family members, and the care team are critical in this process. 
Cornerstone Nutrition: To build an anti-cancer shield, the nutritional supplement strategy for cancer patients should first focus on cornerstone nutrition - proteins, vitamins, minerals. These nutrients are key to building the body's cancer shield. Proteins are fundamental to cell repair and immune system function; Vitamins and minerals are essential for the body's metabolism and protective mechanisms. Protein: High-quality protein** includes fish, chicken breast, soy products and dairy products. The recommended daily intake is adjusted according to individual circumstances, and the general recommendation is 1. per kilogram of body weight2 to 15 grams of protein. Vitamins & Minerals: Fresh fruits and vegetables, nuts, and whole grains are good for vitamins & minerals**. In particular, foods rich in antioxidants, such as blueberries, tomatoes, and carrots, can help fight cancer. Nutrient-dense: Strategic food choices: Choosing nutrient-dense foods is especially important for cancer patients. This means that every bite of food should be rich in essential nutrients. Omega-3 fatty acids, such as deep-sea fish (salmon, mackerel) and flaxseed, are effective in fighting inflammation and boosting immune function. High-fiber foods, such as oats, whole-grain bread and vegetables, promote gut health and help detoxify. Eating habits: small and frequent small and frequent runs: Cancer patients often experience loss of appetite, and small, frequent meals can help maintain a steady intake of energy and nutrients. Liquid nutrition: When solid food intake is difficult, a protein- and energy-rich liquid nutrition supplement is a good choice. For example, a nutrient-dense shake or soup. While food is nutritionally optimal**, supplements can provide the necessary nutritional support in certain situations. Choice: Prefer natural ingredients, low-added supplements, and avoid high sugar and artificial additives. Use: Choose and use nutritional supplements under the guidance of a healthcare professional to ensure safety and effectiveness. Psychological nutrition: The mental health of cancer patients has a direct and indirect impact on nutritional status. Maintaining a positive mindset and improving quality of life through appropriate psychological support and social activities are also part of a nutritional supplementation program. Psychological support: Participating in a support group for cancer patients and talking to others who are going through the same experience** can provide psychological comfort and practical advice. Relaxation techniques: Try meditation, yoga or light exercise to reduce stress and promote physical and mental health. 
Nutritional supplementation is an all-encompassing challenge for cancer patients, covering many aspects of diet, lifestyle and mental health. By implementing the above strategies, cancer patients can effectively improve their nutritional status, thereby supporting the ** process and improving their quality of life. Remember, working closely with your care team to develop a personalized nutrition plan is the key to success.
