Diet can influence white blood cell (WBC) levels. Nutrient-rich foods like fruits, vegetables, whole grains, and lean proteins support immune function, potentially increasing WBC production. Deficiencies in vitamins (e.g., B12, folate) or minerals (e.g., zinc) may lower WBC counts, weakening immunity. Conversely, chronic inflammation from poor diets high in processed foods can elevate WBC levels, indicating stress or infection. For patients using ceftriaxone injection wholesale, a balanced diet enhances treatment efficacy by supporting immune response. Always consult a healthcare provider for personalized advice, as diet alone cannot replace medical interventions for serious conditions affecting WBC levels.
