Diet and nutrition form the foundation of good health and longevity. Our diets play a dual role when it comes to health and disease: a balanced diet preserves health and lowers the risk of non-communicable diseases, while a consistent nutrient-rich diet during cancer treatment upholds healing, recovery and energy levels.
Diet’s role in oncology
For individuals undergoing cancer treatment, nutrition becomes far more than a matter of general wellness — it becomes a vital component of healing. Cancer and its treatments place immense stress on the body, resulting in a greater need for energy, protein, vitamins, and minerals. Adequate nutritional intake supports tissue repair, maintains immune function, preserves healthy body weight, and enhances the body’s ability to tolerate and recover from medical therapies. When these needs are unmet, patients face a greater risk of malnutrition and cancer cachexia, a serious condition marked by involuntary weight loss, muscle wasting, weakness, and reduced physical capacity.
In addition, cancer-related fatigue is a common, distressing symptom experienced by patients. Nutrient-dense foods, help stabilise energy levels by reducing inflammation, preserving muscle mass, and maintaining metabolic balance. Thus, nutrition plays a both supportive and a therapeutic role.
