Radiation therapy is a common treatment used to fight cancer. It works by using high-energy rays to target and kill cancer cells. This therapy can be very effective, but it also comes with side effects that can make it difficult to eat.
Good nutrition is crucial during radiation therapy because it helps your body stay strong and heal faster. Eating the right foods can help you keep up your energy, maintain your weight, and better handle the side effects of treatment.
Some of the common side effects of radiation therapy include mouth sores, fatigue, and changes in taste. These can make eating a challenge, but with the right diet, you can manage these issues more easily.

Foods to prioritize during radiation therapy
Protein Power
Protein is essential for tissue repair and immune function, especially during radiation therapy when your body is under significant stress and working to heal. Adequate protein intake can help repair damaged tissues and support the immune system, making recovery smoother.
Examples of protein-rich foods include lean meats, fish, poultry, eggs, beans, tofu, nuts, and seeds. Protein supplements can also be an option to help meet your needs, but it’s important to consult a doctor or registered dietitian before adding them to your diet to ensure they are appropriate for your specific situation.
Fruits and Vegetables
Fruits and vegetables play a vital role in providing essential vitamins, minerals, and antioxidants that support overall health and aid in the healing process. Eating a variety of colorful fruits and vegetables can ensure you’re getting a wide spectrum of nutrients.
For those experiencing mouth sores from radiation therapy, cooked vegetables and smoothies made from fresh fruits and vegetables can be gentler on the mouth and easier to consume.
Healthy Fats
Healthy fats, particularly unsaturated fats, are important for energy and cell health. Including sources of healthy fats in your diet can provide a concentrated source of energy, which is particularly beneficial if you’re struggling to maintain your weight. Recommended sources of unsaturated fats include olive oil, avocado, nuts, and seeds.
Hydration Heroes
Staying hydrated is crucial during radiation therapy to help prevent fatigue and constipation. Adequate fluid intake supports bodily functions and overall health. It’s recommended to drink water, clear broths, and electrolyte-rich drinks to maintain proper hydration levels.
Ensuring you consume enough fluids throughout the day can make a significant difference in how you feel and your ability to cope with treatment side effects.

Foods to minimize or avoid during radiation therapy
Spicy and Acidic Foods
Spicy and acidic foods can exacerbate mouth sores, leading to increased discomfort and irritation.
It is advisable to avoid ingredients like chili peppers, citrus fruits, and tomatoes, which can be particularly harsh on sensitive mouth tissues. Instead, opt for milder alternatives that provide similar nutrients.
For example, sweet bell peppers can replace chili peppers, while melons and bananas can be good substitutes for citrus fruits. Steamed or roasted vegetables like carrots and squash can offer a gentler option with similar nutritional benefits to tomatoes.
Raw and Undercooked Foods
During radiation therapy, the immune system may be weakened, making it essential to exercise caution with raw and undercooked foods due to the elevated risk of foodborne illnesses.
It is recommended to avoid consuming raw fish (such as sushi), undercooked meats, and unpasteurized dairy products. These can harbour harmful bacteria that can overwhelm a compromised immune system.
Instead, ensure all animal products are thoroughly cooked and choose pasteurized dairy options only.
Highly Processed Foods
Highly processed foods often provide minimal nutritional value and can contribute to inflammation, which is unfavorable during the healing process.
Foods such as sugary drinks, packaged snacks, and fried foods should be minimized or avoided. These foods are typically high in unhealthy fats, sugars, and preservatives, which can exacerbate inflammation and offer little in terms of essential nutrients.
To maintain a healthy diet, focus on whole foods, including fresh fruits and vegetables, whole grains, lean proteins, and healthy fats.
Alcohol
Alcohol can have several negative interactions with radiation treatment, including exacerbating dehydration and worsening side effects like fatigue and mouth dryness. Additionally, alcohol can irritate the mucous membranes and potentially interfere with the healing process.
It is advisable to limit or avoid alcohol consumption during treatment to support better hydration and overall health. Opt for nutrient-rich, non-alcoholic beverages such as herbal teas, diluted fruit juices, and water with a splash of lemon or cucumber to stay refreshed without the adverse effects of alcohol.

Managing Side Effects Through Diet
Mouth Sores
Mouth sores can make eating and drinking uncomfortable during treatment. To minimize discomfort, opt for soft foods that are easier to chew and swallow, such as mashed potatoes, yogurt, and scrambled eggs.
It is beneficial to consume foods at cool or lukewarm temperatures, as extremely hot or cold foods can exacerbate sores. Adding broth or sauces to your meals can help keep food moist and lessen irritation.
In addition to dietary choices, using mouth rinses and other oral care products as recommended only by your doctor can aid in managing mouth sores and maintaining oral hygiene.
Nausea and Vomiting
Managing nausea and vomiting often involves selecting bland, easily digestible foods. Items like crackers, toast, and plain rice can be gentle on the stomach. Ginger, known for its anti-nausea properties, can be particularly helpful; consider integrating ginger tea or consuming ginger in small, manageable amounts. Acupressure on specific points, such as the inner wrist, may also provide relief from nausea as part of a broader management strategy.
Fatigue
Fatigue is a common side effect that can be alleviated through diet. Eating smaller, more frequent meals can help maintain steady energy levels. Focus on incorporating energy-boosting nutrients by consuming foods rich in complex carbohydrates, such as whole grains, along with lean proteins, like chicken or tofu. Including a variety of fruits and vegetables can also supply essential vitamins and minerals to support overall energy and stamina.
Taste Changes
Taste changes can make meals less enjoyable, but adjusting your cooking methods and seasonings can help. Experimenting with different spices and herbs can add flavor and make foods more palatable.
Trying new cooking methods like grilling or roasting can also enhance the taste and texture of foods. Keeping an open mind and testing various combinations can help you identify what works best for your altered taste buds.
Conclusion
In summary, maintaining a balanced and nutritious diet is crucial to support the body during radiation therapy.
Selecting gentle, easily digestible foods can help manage nausea and vomiting, while incorporating energy-boosting nutrients and frequent small meals can combat fatigue. Experimenting with spices, herbs, and different cooking methods can make meals more palatable despite taste changes.
Open communication with your radiation oncologist is essential for personalized guidance. With good nutrition and a positive mindset, you can enhance your overall well-being and boost the effectiveness of your treatment journey.
