Foods to Increase White Blood Cell (WBC) Count

White blood cells (WBCs), also called leukocytes, are an important part of the immune system. They help the body identify and fight infections caused by bacteria, viruses, fungi and other harmful microorganisms. When white blood cell levels are low, the body may become more vulnerable to infections and illnesses.

Many people search for the best food to increase white blood count when they receive a blood test showing low WBC levels. While nutrition plays an important role in supporting immune health, it is important to understand that no single food can instantly raise white blood cell counts. In many cases, low WBC counts are related to infections, nutritional deficiencies, medications, autoimmune diseases, bone marrow disorders or cancer treatments, and medical evaluation may be necessary.

A balanced diet rich in protein, vitamins, minerals and antioxidants can help support the body's ability to produce healthy blood cells and maintain immune function. This article explains the best foods, nutrients, lifestyle habits and dietary strategies that may help support healthy white blood cell levels.

What Are White Blood Cells?

White blood cells are immune cells that protect the body from infections and foreign substances. They circulate through the blood and tissues, helping identify and eliminate harmful pathogens.

Major types of white blood cells include:

• Neutrophils
• Lymphocytes
• Monocytes
• Eosinophils
• Basophils

Each type has a different role in defending the body against infections and supporting immune responses.
