Alterations of taste and smell
Alterations in taste can be related to unknown effects of cancer, radiation treatment, dental problems, mucositis and infection (thrush), or medications. Cancer patients undergoing chemotherapy frequently report changes in their sense of taste, specifically a bitter taste sensation during administration of the cytotoxic drugs. One study measured the taste thresholds among cancer patients under chemotherapy compared with controls. In this study, 62% of patients complained of taste disorders associated with the chemotherapy medications. Taste dysfunction can result in food avoidance, inducing weight loss and anorexia, all of which can have significant consequences on patients' quality of life. Simply changing the types of foods eaten as well as adding additional spices or flavorings to foods may help. Citrus may be tolerated well if no mouth sores or mucositis is present. Rinsing the mouth before eating may help improve the taste of food.
While undergoing cancer therapy, patients may experience taste changes or develop sudden dislikes for certain foods. Their sense of taste may return partially or completely, but it may be a year after therapy ends before their sense of taste is normal again. A randomized clinical trial found that zinc sulfate during treatment may be helpful in expediting the return of taste after head and neck irradiation.[Level of evidence: I]

- Try favorite foods.
- Plan to eat with family and friends.
- Have others prepare the meal.
- Try new foods when feeling best.
- Substitute poultry, fish, eggs, and cheese for red meat.
- A vegetarian or Chinese cookbook can provide useful nonmeat, high-protein recipes.
- Use sugar-free lemon drops, gum, or mints when experiencing a metallic or bitter taste in the mouth.
- Add spices and sauces to foods.
- Eat meat with something sweet, such as cranberry sauce, jelly, or applesauce.
