Navigating nutrition during cancer treatment can feel overwhelming. With so much buzz about diets and supplements, it’s easy to feel lost. “Here’s the truth: good nutrition isn’t about perfection — it’s about staying strong, managing side effects and setting yourself up for recovery,” says Jaclyn Bart, registered dietitian with HonorHealth Cancer Care.
Food for thought
After a cancer diagnosis, what you eat can become a big focus for you and your loved ones. Many people wonder how nutrition might impact cancer and its treatment. You might be asking yourself:
- Should I eat only organic or non-GMO foods?
- Is a ketogenic diet beneficial?
- Would going vegan help?
- Are there specific supplements I should take?
- Does sugar fuel cancer?
“These are valid concerns, but with so much conflicting information online, it’s essential to rely on trusted, evidence-based guidance,” says Jaclyn. “Consulting with a nutritionist or cancer dietitian can help clarify what’s right for you and support your treatment journey.”
The power of proper nutrition
The primary goal of nutrition during cancer treatment should be maintaining strength to tolerate treatment and preparing for recovery. Many patients don’t realize their risk for malnutrition or dehydration, which can impact treatment effectiveness. Underconsumption of food or nutrients often results from cancer treatments and their side effects, making professional guidance critical.
Proper nutrition for cancer patients means focusing on both quality and quantity — ensuring the right nutrients are consumed in appropriate amounts to maintain your health and support during treatment.
What is the best cancer-fighting diet?
A plant-based, vegan diet can be really helpful during cancer treatment because it’s packed with nutrient-rich foods that support your overall health and strengthen your immune system. Some of the best types of foods to eat during chemotherapy or other cancer treatments are:
- High-quality, plant-based proteins
- Beverages that can keep you hydrated, this may include electrolytes or coconut water which is high in potassium
- Fruits and vegetables (types vary depending on side effects you’re experiencing from treatment, such as diarrhea or constipation)
- Healthy fats such as avocados, nuts and seeds
A vegan diet can provide essential vitamins, minerals and antioxidants that help reduce inflammation and promote healing, supporting both your body’s fight against cancer and recovery.
