What dietary changes should I make during Ovarian Cancer treatment

Dietary Guidance During Ovarian Cancer Treatment

I'm glad you're thinking about nutrition during your treatment—this is an important part of supporting your body through cancer care. Let me share what the evidence shows about dietary approaches during active treatment.

Key Principles for Cancer Treatment Nutrition

According to ASCO (American Society of Clinical Oncology) guidelines, there is currently insufficient evidence to recommend for or against specific dietary interventions during active cancer treatment. This means doctors don't yet have definitive proof that one particular diet is better than another during chemotherapy or other treatments.

However, this doesn't mean nutrition doesn't matter. Rather, it means the focus should be on general healthy eating principles rather than restrictive diets.

What the Evidence Supports

Focus on Whole Foods & Anti-Inflammatory Eating

Research from integrative oncology experts recommends:

• Plant-based, whole foods rich in antioxidants and anti-inflammatory compounds
• Colorful vegetables and fruits (aim for variety—different colors provide different nutrients)
• Whole grains like quinoa, farro, and barley
• Healthy fats from sources like olive oil, avocados, nuts, and fatty fish (salmon, sardines)
• Adequate protein to support cell repair and maintain muscle mass during treatment
• Fermented foods like kefir and kimchi to support gut health

Gut Health Matters

Your gut microbiome (the bacteria in your digestive system) plays a crucial role during cancer treatment. According to research by Dr. [removed] Thomas presented at ASCO, poor gut health can:

• Reduce immunotherapy effectiveness by up to 40%
• Increase treatment side effects
• Reduce response to chemotherapy

To support gut health:

• Eat diverse, colorful fruits and vegetables (aim for 30 different varieties per week)
• Include prebiotic fibers (chicory, beans, leeks, garlic, nuts)
• Consider probiotics, especially lactobacillus strains
• Incorporate medicinal mushrooms (turkey tail, lion's mane, reishi)

What to Avoid or Limit

• Ultra-processed foods (foods in boxes/cans with long ingredient lists of chemicals)
• Excessive sugar and sugary drinks (cancer cells preferentially use glucose)
• Processed and smoked meats (limit red meat to less than 18 ounces per week)
• Excessive dairy (some patients become lactose intolerant during treatment)
• Alcohol

Important Considerations During Treatment

Manage side effects first: If you're experiencing nausea, loss of appetite, or difficulty swallowing, the priority is eating something nutritious rather than following a perfect diet. Work with your healthcare team on managing these symptoms.

Avoid restrictive diets during treatment: While intermittent fasting and ketogenic diets show promise in research, these should only be considered with your oncologist's approval, as they may not be appropriate during active chemotherapy.

Hydration is critical: Drink adequate fluids daily—water is ideal, but broths and electrolyte beverages can help if you're experiencing nausea.

Questions to Ask Your Oncology Team

1. Should I work with an oncology dietitian? (Look for credentials like "CSO"—Certified Specialist in Oncology Nutrition)
2. Are there specific foods I should avoid based on my treatment plan?
3. Do any of my medications interact with supplements or specific foods?
4. What are the signs I'm not getting adequate nutrition, and when should I call?
5. Are there clinical trials studying nutrition interventions for ovarian cancer patients?

The Bottom Line

According to integrative oncology guidelines, the goal is to make your body "as inhospitable as possible" to cancer growth while supporting your resilience through treatment. This means:

• Eating mostly whole, plant-based foods
• Supporting your gut health with diverse vegetables and fermented foods
• Maintaining adequate protein and calories
• Avoiding processed foods and excess sugar
• Working with your care team on individual adjustments

Your oncologist and an oncology-trained dietitian can tailor these recommendations to your specific situation, treatment plan, and any side effects you're experiencing.
