Kidney cancer treatment, such as targeted therapy, can have side effects that affect your relationship with food, such as poor appetite, nausea, or mouth sores that make eating challenging.

At the same time, cancer treatment generally calls for increased calorie and protein intake because surgery, targeted therapy, and cancer-related inflammation can break down muscle faster than usual, says Alison Tierney, RD, the founder of Wholesome, a telehealth nutrition practice supporting people through cancer treatment and survivorship, based in Oconomowoc, Wisconsin.

But if your kidney function drops significantly, which can occur after a nephrectomy, your nephrology team may recommend limiting protein intake instead to ease your kidney’s workload, Tierney notes.

 In these cases, they may also recommend reducing your intake of sodium, potassium, and phosphorus, to help prevent imbalances that can affect your heart, bones, and overall health.

The following whole, minimally processed, plant-forward foods can help you maintain strength and muscle mass, support your immune system, manage cancer treatment side effects, and nourish your body as you recover. Remember to stay flexible if treatment side effects make certain foods difficult to tolerate, Tierney says, and check with your care team before making any changes to your diet.
