Nutrition and diet are crucial for overall health and play a significant role in cancer care. A nutrient-rich diet supports healing, recovery, and energy levels during cancer treatment, helping patients cope with physical and emotional challenges. Adequate intake is vital to prevent malnutrition and cancer cachexia, characterized by weight loss and muscle wasting. Nutrient-dense foods can also help manage cancer-related fatigue by reducing inflammation and maintaining metabolic balance, thus supporting patients through their treatment journey.
