Understanding Chemo-Induced Nausea
Chemotherapy drugs are powerful medications designed to kill fast-growing cancer cells. Unfortunately, they can also affect other rapidly dividing cells in the body, including those lining the gastrointestinal tract. This can lead to side effects like nausea and vomiting, which can be distressing and interfere with treatment. The good news is that dietary adjustments can make a significant difference in how you feel, allowing you to get the calories and nutrients you need to stay strong.
Soothing Foods for Nausea Relief
When your stomach feels unsettled, the goal is to choose foods that are gentle, low-odor, and easy to digest. Here are some of the best food and drink options to consider:
- The BRAT Diet: This classic combination—Bananas, Rice, Applesauce, and Toast—is a foundation for a bland diet. These foods are low in fat and fiber, making them easy on the stomach.
- Clear Liquids and Broths: Stay hydrated by sipping on clear liquids throughout the day, such as low-sodium chicken or vegetable broth, apple juice, flat ginger ale, or sports drinks. Ice pops or gelatin can also be good options.
- Bland Starches: Plain pasta, boiled potatoes, and plain cereals like cream of wheat or oatmeal are gentle on the digestive system.
- Soft Fruits and Vegetables: Canned peaches, pears, applesauce, or cooked, soft vegetables like carrots and squash are easy to tolerate.
- Low-Fat Proteins: Protein is crucial for maintaining strength. Choose options like skinless, baked or broiled chicken, hard-boiled eggs, or cottage cheese.
- Cold Foods: For many people, cold foods have less aroma and are more appealing than hot, steaming meals. Try cold chicken sandwiches, yogurt, or smoothies.
Foods and Triggers to Avoid
Just as some foods can help, others can worsen nausea. It is often best to avoid the following during periods of intense nausea:
- Fatty and Fried Foods: Greasy foods like french fries, heavy meats, and fried eggs are difficult to digest and can trigger stomach upset.
- Spicy and Highly Seasoned Foods: These can irritate the stomach lining and increase nausea.
- Overly Sweet Foods: Rich desserts, cakes, and candies can be overwhelming and make nausea worse for some individuals.
- Strong Odors: The smell of cooking or specific foods can be a powerful trigger. Avoiding strong aromas from coffee, fish, or garlic can be helpful.
- Heavy Dairy: While some low-fat dairy like yogurt or cottage cheese may be tolerated, full-fat milk and ice cream can be harder to digest.
- Favorite Foods: Avoid eating your favorite foods while feeling sick. You could develop a lasting aversion to them.
A Comparison of Tolerable vs. Irritating Food Choices
| Tolerable Options | Irritating Options |
|---|---|
| Dry crackers and toast | Greasy, fried foods |
| Plain white rice | Spicy, heavily seasoned dishes |
| Chicken broth | Cream-based soups or sauces |
| Applesauce and canned fruit | Very sweet desserts |
| Baked skinless chicken | Fatty cuts of meat or fried chicken |
| Herbal tea (ginger, peppermint) | Strong-smelling coffee or fish |
| Chilled foods and beverages | Hot, steaming dishes |
| Boiled potatoes | French fries or hash browns |
Dietary Strategies and Tips
Beyond choosing the right foods, how you eat is just as important. These strategies can help minimize nausea and make eating more manageable.
- Eat Small, Frequent Meals: An empty stomach can worsen nausea, but a full one can be overwhelming. Try having five or six small meals throughout the day instead of three large ones.
- Time Your Fluids: Sip on fluids slowly throughout the day, preferably between meals rather than with them. This prevents feeling too full and ensures you stay hydrated.
- Keep Snacks Handy: Place bland snacks like crackers or dry toast by your bedside. Eating a few bites before getting out of bed can help with morning nausea.
- Avoid Lying Down After Meals: Stay upright for at least 30 to 60 minutes after eating to aid digestion and prevent discomfort.
- Get Fresh Air: A well-ventilated eating area can help reduce food odors. Eating outdoors or in a different room from where the food was cooked can be beneficial.
- Suck on Candies: Hard candies with flavors like ginger or lemon can help with a metallic taste in the mouth and can be soothing.
- Use Plastic Utensils: If foods taste metallic, switching to plastic cutlery can make a difference.
Conclusion
Navigating nausea during chemotherapy can be challenging, but making strategic food choices and adopting helpful eating habits can significantly improve comfort and quality of life. By focusing on bland, easily digestible, and hydrating foods while avoiding triggers, you can support your body's nutritional needs throughout treatment. Always discuss dietary changes with your healthcare team, including an oncology dietitian, to ensure they are appropriate for your specific situation.
