What is the best diet for ovarian cancer patient undergoing therapy? In my experience living with an incurable cancer since 1994, your diet is based on specific priorities below.
Interestingly, a gut microbiome-enhancing diet (below) can accomplish all of the objectives above. Further, according to research, a healthy gut microbiome can enhance the efficacy of therapies while reducing the risk of side effects.
Below is a 14-day, treatment-ready diet outline for a newly diagnosed ovarian cancer patient. The plan emphasizes maintaining strength, supporting immune function, reducing inflammation, preserving gut health, and minimizing treatment-related side effects (fatigue, nausea, bowel changes). It is flexible and can be adjusted for appetite, taste changes, or treatment phase.
Adequate protein to preserve lean mass and aid healing
Complex carbohydrates for energy and bowel regularity
Healthy fats to reduce inflammation and support calorie needs
Fiber-rich, gut-supportive foods (as tolerated)
Micronutrient density (folate, iron, magnesium, zinc, vitamin D)
Hydration (2–2.5 L/day unless restricted)
Food safety is important: avoid unpasteurized products, raw eggs, undercooked meats, and unwashed produce.

Thank you,
Ovarian cancer is characterized by dysbiosis, referred to as oncobiosis in neoplastic diseases. In ovarian cancer, oncobiosis was identified in numerous compartments, including the tumor tissue itself, the upper and lower female genital tract, serum, peritoneum, and the intestines.
Colonization was linked to Gram-negative bacteria with high inflammatory potential. Local inflammation probably participates in the initiation and continuation of carcinogenesis. Furthermore, local bacterial colonies in the peritoneum may facilitate metastasis formation in ovarian cancer.
Vaginal infections (e.g. Neisseria gonorrhoeae or Chlamydia trachomatis) increase the risk of developing ovarian cancer. Bacterial metabolites, produced by the healthy eubiome or the oncobiome, may exert autocrine, paracrine, and hormone-like effects, as was evidenced in breast cancer or pancreas adenocarcinoma.
We discuss the possible involvement of lipopolysaccharides, lysophosphatides and tryptophan metabolites, as well as, short-chain fatty acids, secondary bile acids and polyamines in the carcinogenesis of ovarian cancer.
We discuss the applicability of nutrients, antibiotics, and probiotics to harness the microbiome and support ovarian cancer therapy. The oncobiome and the most likely bacterial metabolites play vital roles in mediating the effectiveness of chemotherapy.
Finally, we discuss the potential of oncobiotic changes as biomarkers for the diagnosis of ovarian cancer and microbial metabolites as possible adjuvant agents in therapy.
