Proper nutrition is essential for cancer patients to support strength, immunity, and healing. A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can help manage treatment side effects and maintain energy. Choose antioxidant-rich foods like berries, leafy greens, and carrots. Include protein sources such as eggs, chicken, fish, tofu, or legumes to support muscle repair. Whole grains like brown rice and oats provide sustained energy. Stay hydrated with water, herbal teas, or broths. Avoid processed foods, sugary snacks, and alcohol. Consult a dietitian for personalized guidance tailored to individual needs and treatment plans.
