foods to boost immune system during chemo

Chemotherapy presents notable difficulties for the body, such as weakening the immune system. Although medical treatments are imperative, it is important to also pay attention to nutrition and include immune-enhancing foods in your diet to offer extra assistance throughout this challenging process.

This article will examine a variety of nourishing foods that can reinforce your immune system while undergoing chemotherapy. 

Citrus Fruits

Citrus fruits like oranges, lemons, and grapefruits are well-known for their abundance of vitamin C, making them great options for boosting your immune system. Vitamin C, a strong antioxidant, helps in the creation of immune cells that are crucial for protecting the body against infections. These fruits can be enjoyed as a revitalizing snack or their juices can be added to smoothies for hydration. 

Leafy Greens

Leafy greens, including spinach, kale, and Swiss chard, provide essential nutrients like vitamins A, C, and E. These antioxidants play a role in bolstering the immune response, helping protect your cells from damage. Incorporate leafy greens into your diet by tossing them in salads, sautéing them, or blending them into a delicious green smoothie.


Garlic has been used for centuries for its medicinal properties. It contains sulfur compounds that not only lend flavor to your meals but also help stimulate the immune system. Garlic possesses antimicrobial properties, aiding in the fight against infections. Add fresh garlic to cooked dishes, soups, and sauces to enhance both the taste and the immunity-boosting qualities.


Berries are packed with antioxidants, vitamins, and minerals essential for a robust immune system. Blueberries, strawberries, raspberries, and blackberries are all excellent options. These colorful fruits contain high levels of vitamin C, as well as flavonoids that help strengthen the immune system. Enjoy them fresh, frozen, or mixed into smoothies and yogurt.

Probiotic Foods

Probiotics are good bacteria that support the well-being of your digestive system, which is important for a strong immune system. To enhance the health of your gut microbiome, include fermented foods like yogurt, kefir, sauerkraut, and kimchi in your diet. You may also consider taking probiotic supplements, but it is advisable to seek advice from a healthcare provider. 


Ginger has antimicrobial, anti-inflammatory, and antioxidant properties that can support your immune system during chemotherapy. It can help soothe an upset stomach and alleviate nausea, a common side effect of treatment. Add grated ginger to teas, soups, or incorporate it into marinades or stir-fries for a flavorful immune-boosting touch.

Protein-Rich Foods

Adequate protein intake is essential during the chemotherapy process to support tissue repair and maintenance of the immune system. Opt for lean protein sources like poultry, fish, tofu, beans, and lentils. These foods also provide other essential nutrients, including zinc and iron, which play a vital role in immune function.


While undergoing chemotherapy, it is crucial to prioritize your nutrition to support your immune system. The foods listed above are just a starting point towards building a well-rounded diet that can enhance your body’s ability to fight infections and promote overall health. Remember to consult with your healthcare team or a registered dietitian to ensure your specific dietary needs are met. Stay strong, stay nourished, and remain optimistic on your healing journey.
