Registered dietitian-nutritionist Michelle Myers discusses how to relieve some common symptoms from cancer treatment.
Nutrition plays an important role in the lives of those who have been diagnosed with cancer. As people undergo treatment and enter survivorship, their relationship with food can change. Memorial Sloan Kettering’s clinical dietitian-nutritionist team is here to help with any concerns that come up. This can include everything from food-related side effects and safe food handling and preparation to special and restricted diets.
“Everyone with cancer could benefit from meeting with a member of our team, regardless of what stage of treatment or survivorship they’re in,” says Michelle Myers, a registered dietitian-nutritionist at MSK. “I love getting patients back to eating and thinking about food the way they used to.”
Medical nutrition therapy is available for all MSK patients, says Ms. Myers, though people who are interested are encouraged to first speak with an MSK doctor or nurse.
“Whether you feel too nauseous to eat during chemotherapy or you saw something on the internet about a food you should avoid, or if you want help with maintaining your weight after treatment, we’re here to assist for all of it,” she says.
To learn more about how cancer care can affect nutrition and diet, we asked Ms. Myers some common questions.
What kind of diet should people follow during cancer treatment?
There’s no right diet for everyone. Your care team can help you figure out a plan that works for you. During treatment, you should focus on getting enough calories and protein while managing your symptoms. Be liberal with what you eat and choose your favorite foods — don’t worry too much about what those foods are.
To control symptoms from treatment, my recommendations depend on the type of care you’re receiving and specifically what doesn’t feel right. For example, those receiving chemotherapy may experience a loss of appetite, nausea, constipation, or diarrhea. I have specific instructions to help with each of those side effects.Back to top
Let’s start with people experiencing nausea during chemotherapy. What diet is good for them?
To alleviate nausea while undergoing cancer treatment, try eating smaller portions of food, but eat more often. You should avoid food that’s high in fat, overly spicy, or overly sweet. This includes fried foods, pastries, or foods made with a lot of spices. High-fat foods stay in your stomach longer and are harder to digest. Avoid strong odors, such as cooking smells, smoke, or perfume, which can make nausea worse. Instead, try a bland diet consisting of foods like crackers, toast, pasta, yogurt, and skinless chicken.Back to top
What about people who have constipation during cancer treatment?
I recommend gradually increasing your fiber intake and getting enough fluids. Foods that are high in fiber include fruits and vegetables, as well as whole grains, such as some cereals, pasta, and brown rice. It’s crucial to drink enough throughout the day to keep the stool soft and to prevent gas and bloating.Back to top
Are there nutritional tips for preventing diarrhea during cancer treatment?
The most important thing with diarrhea is preventing dehydration. I tell my patients that they should drink at least 64 ounces of fluids per day. That’s about the size of a two-liter bottle. Water is obviously a good fluid, but people can also drink fruit juice or tea. In order to replace sodium and potassium, which may be lost with diarrhea, you may want to drink an electrolyte-containing beverage such as Gatorade or unflavored Pedialyte. It’s vital to avoid very hot or cold foods, foods high in sugar or fat, or spicy foods. These are all hard on the digestive system.Back to top
How can caregivers support a loved one who doesn’t want to eat?
I understand how upsetting it can be to watch a loved one who won’t eat. First, you should try to figure out if there are any specific symptoms that are going on besides the fact that they just don’t have an appetite. After that, you should encourage and support your loved one without applying too much pressure. Don’t force them to start eating if they don’t want to and don’t force them to finish their plate.
It’s important to make eating a pleasant experience. That could mean putting on music, setting the room to a more comfortable temperature, or including loved ones at the table. I also encourage people to try experimenting with different food temperatures and textures and using smaller plates so the amount to eat doesn’t seem overwhelming.Back to top
What about after treatment? Is there anything people should or should not eat?
After treatment, when you’re feeling a little better and not experiencing side effects, focus on choosing healthy foods. Maintain a well-balanced diet of lean protein, whole grains, healthy fats, and a variety of fruits and vegetables.Back to top
