Why Do White Blood Cells Drop During Chemotherapy?
Chemotherapy drugs target rapidly dividing cancer cells but also suppress bone marrow, which produces blood cells. As a result, white blood cells, red blood cells, and platelets may decrease. When white blood cell counts are low, immunity drops, making patients more vulnerable to infection and fatigue—highlighting the importance of nutrition and supportive care.
Diet Principles: Balanced Plate + Enough Protein
Protein is essential for producing white blood cells. During chemotherapy, patients need about 1.5 times more protein than usual.
Example:
- 60kg male: ~90g protein per day
- 50kg female: ~75g protein per day
Simple dietary recommendations:
- Base meals on a balanced plate: 2–3 portions vegetables > 1–1.5 portions fruits > ~1 bowl whole grains > 4–5 portions lean protein (fish, chicken, tofu).
- If appetite is poor: add balanced nutrition shakes or oncology-specific supplements.
Nutrition Strategies to Support White Blood Cells
1. Anti-Inflammatory Diet (Mediterranean Style)
Focus on vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish. Foods rich in Omega-3s such as salmon, mackerel, walnuts, and flaxseed help reduce inflammation.
2. Reduce Sugar & Refined Carbs
Avoid white rice and white bread. Choose oats, barley, red beans, and sweet potatoes to stabilize blood sugar and reduce inflammation.
3. Iron Beyond Beef
While beef contains iron, it’s also high in saturated fat. Better options include pork liver, clams, oysters, and duck meat for iron support.
4. Anti-Inflammatory Nutrients
- Vitamin D3 – supports immune regulation
- Vitamin C – antioxidant support
- Curcumin – reduces chemotherapy-related inflammation
- Fish oil (Omega-3) – lowers chronic inflammation
5. Oncology-Specific Nutrition Formulas
When appetite is poor, supplements with fish oil, arginine, nucleotides, and glutamine can reduce white blood cell decline during chemotherapy.
6. Mushroom-Derived Polysaccharides (β-Glucans)
Ingredients from Reishi, Coriolus (PSK/PSP), and yeast β-glucans have shown in clinical studies to help restore white blood cell counts and enhance immune function after chemotherapy.
Lifestyle: Nutrition + Exercise Together
Diverse Phytochemicals
Different vegetables and fruits contain thousands of antioxidants that protect immune cells. Daily recommendations:
- Vegetables: 2–3 servings
- Fruits: ≤2 servings (to avoid excess sugar)
- Best picks: berries, green tea, broccoli, nuts
Moderate Exercise
Research shows regular exercise (walking, resistance training, light jogging) can reduce chemotherapy side effects, improve appetite, and stimulate white blood cell production.
Key Takeaways
Chemotherapy often reduces white blood cells, but you can minimize risks by following three core principles:
- High-Protein Nutrition – daily adequate protein intake
- Anti-Inflammatory Diet – more vegetables, whole grains, healthy fats; less red and processed meat
- Lifestyle Support – moderate exercise + evidence-based supplements
This holistic approach reduces infection risk, supports immunity, and helps patients complete treatment more safely and effectively.
