coping with taste alterations
Why Does Chemotherapy Affect Taste?
One of the lesser-known but significant side effects of chemotherapy is taste alteration, also known as dysgeusia. Many cancer patients report that foods taste metallic, overly sweet, or completely bland. These changes can make eating a challenge, leading to poor nutrition and weight loss. Fortunately, there are strategies to help manage these taste changes and make meals more enjoyable.
Chemotherapy drugs can damage taste buds, alter saliva production, and affect the way nerves transmit taste signals to the brain. Additionally, changes in gut bacteria and inflammation from treatment can contribute to food aversions and altered taste perceptions.
A 2018 study published in the journal Supportive Care in Cancer found that up to 70% of chemotherapy patients experience taste disturbances, with some continuing to have issues even after treatment ends. Understanding this side effect is the first step toward managing it effectively.
Approaches to Managing Taste Changes
1. Experiment with Different Flavors and Textures
Since chemotherapy can dull taste perception, intensifying flavors can make foods more appealing. Try:
Adding citrus (lemon, lime, orange) to water or meals
Using herbs and spices like basil, ginger, or garlic to enhance flavor
Trying cold foods, as they may be easier to tolerate than hot meals
2. Combat Metallic or Bitter Tastes
A common complaint is a persistent metallic taste. To counteract this:
Use plastic or wooden utensils instead of metal
Rinse your mouth before meals with baking soda and water (1/4 tsp baking soda in 1 cup of water)
Avoid processed meats, which can enhance metallic flavors
3. Stay Hydrated and Improve Saliva Flow
Dry mouth can worsen taste alterations. Keep hydrated by:
Drinking lemon-infused water or herbal teas
Eating hydrating foods like cucumbers, watermelon, and soups
Using sugar-free lozenges or chewing gum to stimulate saliva production
The Role of Miracle Berry Tablets
Miracle berries (Synsepalum dulcificum) are a natural way to modify taste perception. These berries contain miraculin, a glycoprotein that temporarily alters taste buds, making sour or bitter foods taste sweet.
How Miracle Berry Tablets Help
Studies have shown that miracle berry tablets can improve the taste of certain foods for chemotherapy patients. A 2019 study in Cancer Treatment and Research Communications found that patients who took miracle berry tablets before meals experienced a significant reduction in metallic and bitter tastes.
How to Use Them:
Place a miracle berry tablet on your tongue and let it dissolve
Try eating tart foods like lemons, vinegar-based dressings, or yogurt
Effects last for about 30–60 minutes, providing temporary relief
While not a cure-all, many patients find that miracle berries make food more enjoyable during treatment.
When to Seek Professional Guidance
If taste alterations lead to severe weight loss, malnutrition, or food aversions, consult a dietitian or oncologist for personalized nutritional support. They may recommend:
Medical nutrition drinks or protein shakes
Zinc supplements, as some studies suggest zinc deficiency may contribute to taste loss
Customized meal plans to maintain calorie and nutrient intake
Conclusion
Taste alterations during chemotherapy can be frustrating, but they don’t have to take away the joy of eating. By experimenting with flavors, managing metallic tastes, staying hydrated, and considering miracle berry tablets, patients can find ways to enjoy food again. With a little creativity and persistence, meals can still be nourishing and satisfying.
