Which Nutrients Can Support Immunity During Lung Cancer Treatment?
During lung cancer treatment, patients’ immune systems often face significant challenges. While surgery, chemotherapy, and radiotherapy are effective in combating tumors, they can also compromise immune cell function. Beyond adhering to medical guidance, proper nutritional support plays a crucial role in maintaining immune function, preserving physical strength, and supporting overall wellbeing.
The Importance of High-Protein Foods
Protein serves as the building block for the immune system, forming antibodies, immune cells, and various signaling molecules. During treatment, patients often require higher amounts of protein than the general population. Sources such as chicken breast, fish, tofu, eggs, and low-fat dairy provide high-quality protein. Adequate protein intake helps preserve muscle mass, reduces fatigue, and supports the production and repair of immune cells.
Vitamin C and Antioxidant Support
Vitamin C not only combats free radical damage but also enhances white blood cell function, improving immune responsiveness. Foods rich in vitamin C include citrus fruits, kiwifruit, strawberries, bell peppers, and leafy greens. In certain cases, under professional medical supervision, high-dose intravenous vitamin C may also be considered to further support the body’s antioxidant capacity.
Immune-Regulating Role of Vitamin D
Vitamin D is known to modulate both innate and adaptive immune responses. Patients with vitamin D deficiency are more prone to infections and reduced immune function. Natural sources include sunlight exposure, deep-sea fish, egg yolks, and fortified dairy products. When necessary, supplementation under medical guidance can help maintain stable blood levels of vitamin D.
Supporting Trace Elements: Zinc and Selenium
Zinc and selenium play key roles in the maturation and function of immune cells. Zinc is abundant in lean meats, nuts, and seafood, while selenium can be found in Brazil nuts, seafood, and whole grains. Although required in small amounts, deficiencies can significantly impair immune function. Ensuring adequate intake helps enhance immune defense during treatment.
Anti-Inflammatory Benefits of Omega-3 Fatty Acids
Chronic inflammation is common among lung cancer patients during treatment. Omega-3 fatty acids have natural anti-inflammatory properties, helping to reduce the burden of inflammation on the body. Rich sources include fatty fish (such as salmon and sardines), flaxseed oil, and walnuts. Appropriate consumption can help maintain immune balance and overall health.
Conclusion：Nutritional support during lung cancer treatment is not just about “eating enough,” but about strategically supporting the immune system. A diet enriched with high-quality protein, vitamin C, vitamin D, essential trace elements, and Omega-3 fatty acids can help the body maintain defense mechanisms and cope with treatment challenges. Collaborating with professional nutritionists or healthcare teams enables personalized plans, ensuring patients receive the optimal support and care throughout their treatment journey.
