21 Energizing and Nutritious Foods For People Undergoing Chemotherapy

Chemotherapy is an intense medical treatment used to target and destroy cancer cells, but it often comes with a wide range of side effects that can leave patients feeling exhausted, nauseous, and weak. During chemotherapy, the body requires extra nutrients and energy to repair damaged tissues, maintain a healthy immune system, and combat the side effects of the treatment. A balanced diet full of nutrient-dense foods can help boost energy levels, support the immune system, and enhance overall well-being during this challenging time.

While there is no one-size-fits-all approach to nutrition during chemotherapy, there are certain foods that can provide the energy and nourishment needed to support the body through treatment. In this article, we’ll explore 21 energizing and nutritious foods that can help people undergoing chemotherapy feel stronger, manage side effects, and improve their quality of life.
