Tips for Eating
At times, it may seem almost impossible to eat when you are receiving chemotherapy. The following suggestions may help you to get the much-needed nutrients and calories, while minimizing other side effects like nausea and vomiting.
Eat smaller, more frequent meals of easily tolerated foods. Avoid fatty, greasy, and spicy foods. They are be harder on your digestive system. Remember to keep your fluid intake up as well. Drink plenty of fluids throughout the course of the day.
It is important to note that nutrition suggestions for a person receiving chemotherapy can be very different from what is recommended for daily healthy eating. This is a good time to ignore the rules. Eat what you want, when you want, and eat what makes you feel good. Try some foods that you may not have liked in the past. You may find that something that you thought was inedible is now pure heaven.
Dealing With Loss of Appetite
Most chemotherapy medications cause some degree of appetite loss, which can range from mild to severe, which can ultimately lead to malnutrition. Usually, the change in appetite is temporary. Your appetite should return once you have completed chemotherapy.
Until this happens, try some of the following tips:
- Eat high-protein, high-calorie foods.
Add extra calories and protein to meals by using ingredients like:
- Milk powder
- Protein powder
- Peanut butter
- Honey, jam, and sugar
- Cheese and cream cheese
- Use liquid supplements that are specially prepared with extra nutrients, which can be found in most health food stores.
- Drink shakes, smoothies, milk, and soup if chewing and eating solid food is a problem.
Eat soft foods that are easy to chew and swallow, such as:
- Soft fruits—bananas, applesauce, watermelon, peaches, and pears
- Cottage cheese
- Mashed potatoes
- Macaroni and cheese
- Custards and puddings
- Scrambled eggs
- Oatmeal or other cooked cereals
Supplement meals with snacks that are rich in protein and calories, like:
- Cheese—soft, hard, and cottage
- Avocado spread on toast or crackers
- Hard boiled eggs
- Full-fat yogurt
- Try to get a lot of calories at breakfast, as this may be the most tolerable meal of the day.
- Eat in a pleasant environment with other people.
Managing Nausea and Vomiting
Nausea and vomiting are very common side effects of chemotherapy. If you are experiencing either, talk with your doctor. There are several drugs that prevent or alleviate nausea and vomiting. These medications can be used before your symptoms appear.
Some things you can do to help manage nausea and vomiting include:
- Eat prior to chemotherapy treatment.
- Eat dry, bland foods like crackers, toast, or breadsticks throughout the day.
- Sit up or lie down with the upper body raised for one hour after eating.
- Avoid eating in the room where food was prepared. The odor may be too strong.
- Avoid eating in a room that is too warm.
- Rinse out your mouth both before and after eating.
- Suck on hard candies, like peppermints or lemon drops, if there is a bad taste in your mouth.
In addition, social support is critical to your recovery. Take advantage of the kindness of others. Let your family and friends help you. Ask for assistance with grocery shopping, meal preparation, and clean up. If you have no one to help you, investigate resources in your area, like a community assistance center, support groups, local churches, social service centers, or senior centers.
If you are having problems eating, talk to your oncologist for a referral to a registered dietitian (RD). An RD can help you develop eating plans that may be better tolerated, while providing calories and nutrients.
One Final—But Important—Note
When you undergo cancer treatment, your immune system weakens. Avoiding
is essential. Take the following steps to prevent this:
- Wash all fruits and vegetables thoroughly, even if you plan on peeling the fruit or vegetable.
- Wash your hands and food preparation surfaces before and after preparing food, especially after handing raw meat.
- Thaw meat in the refrigerator, not on the kitchen counter.
- Be sure to cook meat and eggs thoroughly.
- Avoid raw shellfish and sushi.
- Use only pasteurized or processed ciders and juices and pasteurized milk and cheese.
And remember, your doctors may have some helpful hints of their own. There are also some medications that can stimulate your appetite, reduce nausea, and generally boost your mood.
