There’s more to nutrition during cancer and cancer therapy than counting calories, protein, and carbs. The foods you choose can help you cope with many side effects, such as nausea, vomiting, loss of appetite, diarrhea, chewing and swallowing difficulties, and taste changes. As each person’s medical background and diagnosis is different, so is the response to treatment. Side effects can be severe, mild, or absent. Make sure to discuss with your healthcare team any/all potential side effects of treatment before the treatment starts. Side effects include nausea, diarrhea, constipation, chewing or swallowing, taste alterations, and bloating.
