Food and Your Cancer Treatment

**Disclaimer: This post contains links to affiliate products.


When undergoing treatment, it is essential to understand that both your illness and eating habits may change. For some, treatment may affect how you withstand certain foods, and for others, it may not. Everybody is different and reacts differently to their illness and treatment. Finding what nutrition plans and goals are right for you can help you feel better, have better strength, better stamina, maintain healthy body weight, lower the risk of infection, and heal quicker. Here are just a few things to consider and discuss with your care team regarding nutrition and your cancer treatment.

When going through chemotherapy, side effects like loss of appetite, Diarrhea, constipation, Dry mouth, thick saliva, mouth sores, nausea/vomiting, and changes in your taste and smell may occur. There are many overlaps for tips on maintaining a well-nourished body during treatment. The main things to remember are always to stay hydrated and eat or drink foods high in calories and protein. Remember, there are different needs for your specified treatment plan. Always consult your care team before trying anything new or stopping something.

Fluids are extremely important to prevent dehydration, thin mucous, moisten the mouth, and protect your kidneys. Sources of fluids include:

  • Water (infused with fruit or vegetables for taste if desired)

  • Broths & soups

  • Smoothies & Milkshakes

  • Popsicles 

Heartburn may be an experience that can be uncomfortable. Often, avoiding heartburn triggers can help. These include: 

  • Avoiding tobacco

  • Limiting caffeine

  • Avoiding alcohol

  • Avoid eating 2-3 hours before bedtime

Focus on protein for energy and strength.  Protein is a key component that can help you recover faster and have the strength to continue treatment.

What are examples of high protein snacks?

  • Meats (beef, pork, poultry. Stay away from red meat which can increase hypertension)

  • Fish and seafood

  • Eggs

  • Dairy (milk, yogurt, cheese)

  • Legume (beans lentils)

  • Soy (edamame, tofu, soymilk)

  • Nuts and seeds

  • Protein powders and shakes

Treatment can also cause other food-related effects. For each of the following side effects, we’ve listed a few helpful strategies to overcome the impacts of treatment on your diet and nutrition.
