Boosting White Blood Cell Count: Nutrition Tips for Immunosuppressed Patients - Nutrition

How to increase white blood cells?


I have rheumatoid arthritis, and long-term use of immunosuppressants has led to a decrease in my white blood cell count.
From October 2021 to May 2022, my count fluctuated between 6,000 and 8,000, which was acceptable.
However, since June, my counts have dropped from 7,070 to 8,450, then to 5,710, and by September, it was only 4,830.
Therefore, I would like to consult on how to increase my white blood cell count.

I found some information suggesting that eating one banana a day can help increase white blood cells, along with foods like shiitake mushrooms, black fungus, job's tears, tremella, lotus seeds, mulberries, and legumes.
Since I don't eat much for main meals, I am considering making job's tears into a drink and would like to know if there are other foods that can be blended into a puree or cooked into soups to help increase white blood cell count.

If my white blood cell count drops to an abnormal level, should I consider taking nutritional supplements? If so, which ones? In August, I had a urine protein level of 2+, creatinine of 1.12, and serum potassium of 5.4, so my doctor advised me to limit high-potassium fruits and vegetables.
I initially wanted to make burdock soup but decided against it due to its high potassium content.
In September, my values decreased to trace, 1.03, and 4.2, but I am unsure if I should continue to avoid high-potassium fruits and vegetables.

Hello: A low white blood cell count requires adequate protein intake, as protein provides the necessary materials for the bone marrow to produce white blood cells.
You can choose sources such as pork, beef, chicken, fish, and eggs.
Traditional Chinese herbs like Astragalus, American ginseng, Codonopsis, goji berries, red dates, and Poria can also help increase the number of immunoglobulins.
If your overall caloric intake is insufficient due to not eating much during meals, it will not be possible to increase your white blood cell count.
It is recommended to consider oral nutritional supplements to boost caloric and protein intake.
Regarding your blood test report indicating high potassium levels, you should avoid high-potassium foods such as sweet potato leaves, water spinach, spinach, and amaranth.
Fruits like kiwi, bananas, cantaloupe, cherimoya, and durian are also very high in potassium and should be consumed cautiously and in small amounts.
Additionally, some unrefined whole grains like oats, Job's tears, and burdock also have high potassium content, so please pay special attention to those.
Wishing you peace and well-being! Sincerely, Dietitian Fan Chun-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

Boosting white blood cell (WBC) count, especially for individuals on immunosuppressive therapy, is a critical concern. As you mentioned, your WBC count has been declining, and you are looking for dietary strategies to help increase it. Here are some nutritional tips and considerations that may assist you in this regard.


Nutritional Strategies to Boost White Blood Cell Count
1. Increase Protein Intake: Protein is essential for the production of white blood cells. Foods rich in protein include lean meats (chicken, turkey, beef), fish, eggs, dairy products, legumes (beans, lentils), and nuts. If you find it challenging to consume solid foods, consider protein shakes or smoothies that incorporate these ingredients.

2. Incorporate Immune-Boosting Foods: Certain foods are known to support immune function. These include:
- Mushrooms: Varieties like shiitake and maitake are known to enhance immune function.

- Garlic: Contains compounds that may stimulate the immune system.

- Citrus Fruits: While you need to be cautious with high-potassium fruits, vitamin C-rich foods like oranges and grapefruits can be beneficial.

- Berries: Blueberries and strawberries are high in antioxidants, which can support overall health.

3. Consider Nutritional Supplements: If your dietary intake is insufficient, you might consider nutritional supplements. Products specifically designed for immune support, such as those containing vitamins C, D, and zinc, can be beneficial. However, consult with your healthcare provider before starting any new supplements, especially given your existing health conditions.

4. Hydration: Staying well-hydrated is crucial for overall health and can support the production of blood cells. Aim for adequate fluid intake throughout the day.

5. Avoid High-Potassium Foods: Given your elevated potassium levels, you should avoid foods high in potassium, such as bananas, sweet potatoes, and certain leafy greens. Instead, focus on low-potassium vegetables like carrots, green beans, and bell peppers.

6. Small, Frequent Meals: If your appetite is low, try eating smaller, more frequent meals throughout the day. This can help ensure you are getting enough calories and nutrients without feeling overwhelmed by large meals.

7. Cooking Methods: Opt for cooking methods that enhance the flavor and appeal of your meals, such as steaming, roasting, or stir-frying with healthy oils. This can help improve your appetite and make it easier to consume a variety of foods.

8. Consult a Dietitian: Given your specific health concerns and dietary restrictions, working with a registered dietitian can provide personalized guidance tailored to your needs. They can help you create a meal plan that balances your nutritional needs while considering your potassium levels.


Monitoring and Medical Consultation
It's essential to monitor your WBC count regularly, especially since you are on immunosuppressive therapy. If your WBC count continues to decline or if you experience symptoms such as frequent infections, fatigue, or unusual bruising, it is crucial to consult your healthcare provider. They may recommend further evaluation or adjustments to your medication regimen.

In summary, while dietary adjustments can play a significant role in supporting your immune health, they should be part of a comprehensive approach that includes regular medical care and monitoring. Always consult with your healthcare provider before making significant changes to your diet or starting new supplements, particularly in the context of your existing health conditions.
