Essential Dietary Guidelines for Cancer Patients Undergoing Chemotherapy

What is the diet for chemotherapy?

Hello, I apologize for bothering you.
I would like to ask about my grandfather, who has recently been diagnosed with lung cancer and is currently undergoing chemotherapy.
What kind of diet would be best for him right now? Are there specific foods he should eat or avoid? Also, I've heard that chicken should not be eaten; is that true? Thank you for your help!

Hello! Here are some dietary considerations for your grandfather during chemotherapy for lung cancer:
1.
During chemotherapy, patients may experience changes in their food preferences.
Therefore, it is advisable to prepare foods that the patient enjoys and to adjust seasonings to enhance appetite.
2.
Patients often have poor appetite, so food preparation should be varied, and a small, frequent meal approach should be adopted to stimulate appetite and promote digestion.
3.
Avoid gas-producing foods such as sweet potatoes and leeks.
Pay attention to which foods may cause discomfort and avoid those.
4.
Provide foods with mild odors to reduce unpleasant smell stimuli.
Slightly acidic foods may help increase the patient's appetite, but if there is oral mucositis, acidic foods should be avoided.
5.
Choose slightly sticky foods, as these patients often experience dry mouth and reduced saliva production.
Moist foods (such as stews or noodle soups) are easier to swallow.
6.
Citrus fruits (such as oranges, tangerines, and lemons) can stimulate saliva production.
7.
Try to stay away from the kitchen to avoid the smells from cooking that may trigger nausea and vomiting.
8.
When the patient's appetite is very poor and eating is not ideal, balanced nutritional supplements can be provided.
There are no dietary restrictions against eating chicken during chemotherapy for lung cancer, so chicken can still be included in the diet.
Sincerely,
Nutritionist Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

When caring for a cancer patient undergoing chemotherapy, especially for conditions like lung cancer, it's crucial to focus on a well-balanced, high-calorie diet that supports their nutritional needs while managing side effects from treatment. Here are some essential dietary guidelines to consider:

1. High-Calorie, Nutrient-Dense Foods
Cancer patients often experience weight loss and decreased appetite due to chemotherapy. Therefore, it's important to include high-calorie foods that are also nutrient-dense. Foods such as avocados, nuts, seeds, full-fat dairy products, and healthy oils (like olive oil) can provide the necessary calories and nutrients without requiring large volumes of food.

2. Protein-Rich Foods
Protein is vital for healing and maintaining muscle mass, especially after surgery or during chemotherapy. Encourage the consumption of lean meats (like chicken, turkey, and fish), eggs, legumes, and dairy products. If your grandfather is concerned about eating chicken, it's generally safe unless advised otherwise by his healthcare provider. However, ensure that all meats are cooked thoroughly to avoid any risk of foodborne illness, as chemotherapy can weaken the immune system.

3. Hydration
Staying hydrated is crucial. Encourage your grandfather to drink plenty of fluids, including water, herbal teas, and broths. If he experiences nausea, ginger tea or clear broths can be soothing.

4. Small, Frequent Meals
Instead of three large meals, consider offering small, frequent meals throughout the day. This approach can help manage nausea and make it easier for him to consume enough calories.

5. Avoiding Certain Foods
While there is no blanket list of foods that all cancer patients must avoid, some general guidelines include:
- Raw or Undercooked Foods: Due to a weakened immune system, it's best to avoid raw fish, undercooked meats, and unpasteurized dairy products.

- Highly Processed Foods: Foods high in sugar, salt, and unhealthy fats should be limited as they can contribute to inflammation and other health issues.

- Certain Supplements: Some supplements, especially antioxidants, may interfere with chemotherapy. Always consult with a healthcare provider before introducing any new supplements.

6. Managing Side Effects
Chemotherapy can lead to various side effects, including nausea, taste changes, and mouth sores. Here are some strategies:
- Nausea: Eating bland foods, such as crackers or toast, can help. Ginger and peppermint are also known to alleviate nausea.

- Taste Changes: Encourage the use of herbs and spices to enhance flavor. If certain foods taste metallic, using plastic utensils may help.

- Mouth Sores: Soft, moist foods are easier to eat. Avoid spicy or acidic foods that can irritate the mouth.

7. Consulting with Healthcare Providers
It's essential to work closely with healthcare providers, including oncologists and registered dietitians, to tailor a dietary plan that meets your grandfather's specific needs. They can provide personalized recommendations based on his treatment plan and overall health status.

Conclusion
In summary, a well-balanced, high-calorie diet rich in protein and hydration is essential for cancer patients undergoing chemotherapy. While chicken is generally safe to eat, ensure it is cooked properly. Always consult with healthcare professionals before making significant dietary changes or introducing new supplements. This approach will help support your grandfather's health and well-being during his treatment journey.
