Can cancer patients eat Gynura segetum (also known as "木耳菜")?
Generally speaking, cancer patients can eat Malabar spinach (Basella alba), but it should be consumed in moderation. The detailed explanation is as follows:

Malabar spinach is rich in various vitamins, including vitamin C, vitamin E, and vitamin K. Vitamin C has antioxidant properties and can help cancer patients enhance their immunity, promote collagen synthesis, aid in wound healing and tissue repair. Vitamin E protects cells from damage caused by free radicals and plays a positive role in maintaining normal cellular functions and delaying aging. Vitamin K participates in the blood coagulation process and may help improve coagulation dysfunction that may occur in cancer patients due to treatment or other factors.
The dietary fiber in Malabar spinach promotes intestinal peristalsis and increases stool volume, helping to prevent constipation. During treatment, cancer patients often experience constipation due to reduced physical activity, medication side effects, etc., and consuming Malabar spinach can help improve intestinal function. However, it should be eaten in moderation, as excessive consumption may burden the gastrointestinal system and worsen discomfort symptoms, especially in patients with poor gastrointestinal function due to its cooling nature.
In all cases, it is recommended that patients consult their doctor or a nutritionist before trying new foods to ensure dietary safety and support recovery. At the same time, maintaining a balanced and diverse diet helps improve patients' quality of life and treatment outcomes.
