Should You Avoid Certain Foods During Targeted Therapy?

When undergoing targeted cancer therapy, diet often becomes a concern for many patients. The truth is, there’s no need for overly strict restrictions, but maintaining a light, balanced, and nutritious diet is essential.

1. Focus on balanced nutrition
Targeted drugs work by regulating specific molecular pathways in the body. To support your body’s metabolism and recovery, your diet should include adequate protein, fresh vegetables, and whole grains. Avoid extremes — eating too little may weaken your immunity, while overeating can burden your liver and kidneys.

2. Be cautious with certain foods
Some foods can interfere with drug absorption or metabolism.

• Grapefruit and grapefruit juice are known to affect liver enzymes, which may alter the drug’s effectiveness.

• Herbal supplements and over-the-counter health products should also be used carefully, as their components can interact with your medication.

3. Eat smart, not less
The key to a proper diet during targeted therapy isn’t “eating less,” but eating right. Regular meals, balanced portions, and clean cooking methods (steaming, boiling, stewing) help minimize digestive stress and maintain stable nutrition levels.

4. Seek professional guidance
Before making major dietary changes or taking supplements, always consult your oncologist or a clinical nutritionist. They can provide individualized advice based on your specific medication and health condition.

In short:
Targeted therapy doesn’t mean you must give up your favorite foods — it’s about balance, moderation, and scientific management. Eating right supports the treatment and enhances your quality of life.
