Cancer treatment often takes a heavy toll on the body, making nourishment more critical than ever. While chemotherapy, radiation, and other treatments are necessary for recovery, they can interfere with appetite and digestion, making it difficult for patients to maintain a consistent, healthy diet. As a result, finding ways to nourish the body through these challenges is key to supporting overall well-being during treatment.
Emma Veilleux, a senior dietitian supervisor at the Simms/Mann UCLA Center for Integrative Oncology, emphasizes the importance of being prepared and flexible with food choices. “The side effects of cancer treatments, like nausea, constipation, and diarrhea, can disrupt your ability to eat well,” she explained. “Patients may also experience taste and smell aversions, making foods they normally enjoy seem unappealing.”
With this in mind, Veilleux recommends stocking up on a variety of nutritious foods before treatment begins. “Having an assortment of ready-to-eat meals and snacks on hand allows for flexibility. If you don’t feel like eating one type of food, you can easily switch to something else,” she said.
Stock Up on Convenient, Nutritious Foods
Keeping a selection of ready-to-eat items like yogurt, cottage cheese, fruits, vegetables, and nut butter in the fridge, along with frozen meals in the freezer, can help ensure patients have healthy options available when their appetite fluctuates. “Whether you’re in the mood for pasta or chicken, you can choose from what’s already in your kitchen,” Veilleux explained. “Takeout can also be an option if you’re craving something specific.”
When it becomes difficult to eat due to appetite loss, Veilleux advises using protein shakes or meal-replacement drinks as alternatives to ensure adequate nourishment. “It’s important to eat something, even if it’s not a complete meal.”
Stay Hydrated
Hydration is another crucial aspect of cancer care, especially for those experiencing diarrhea or vomiting. “Electrolyte supplements can help replenish lost fluids,” Veilleux said, adding that patients should consult their doctor or dietitian to choose the right product. While coffee can generally be consumed in moderation, Veilleux recommends abstaining from alcohol during treatment, as it may worsen side effects.
Protein Is Key
Protein needs are elevated during cancer treatment, and Veilleux encourages patients to prioritize protein intake. However, flexibility is also important. “On days when appetite is low, eating anything is better than nothing,” she said. “Even simple, bland foods like saltine crackers or white rice may be easier to tolerate and are still beneficial for maintaining energy.”
Give Yourself Grace
Cancer treatment can be unpredictable, and so can your appetite. Veilleux stresses the importance of giving oneself grace during this time. “Flexibility is essential in coping with treatment’s side effects. Patients should feel empowered to communicate openly with their care team about the challenges they face, as there are medications available to alleviate discomfort,” she noted.
Both patients and their families should approach nutrition with understanding. “It’s vital to remain supportive and patient throughout the treatment process,” Veilleux emphasized. “Sometimes, the most important thing is simply nourishing your body in whatever way works that day.”
