Initially developed in 1980 to evaluate nutritional conditions and surgical risk in gastrointestinal surgery, the prognostic nutritional index (PNI) has since proven to be a valuable tool in various clinical settings. This simple biomarker reflects a patient’s nutritional and immune status, both of which are critical determinants of health and recovery.

The human immune system is a complex network that constantly produces white blood cells, including lymphocytes, to fight infection. This process is internal, so no foods have lymphocytes directly, but certain nutrients are crucial for supporting their healthy function and boosting overall immune response.

Malnutrition is one of the most common causes of low lymphocyte count (lymphopenia) worldwide, highlighting the critical connection between nutritional intake and immune health. So, can diet affect lymphocyte count and influence your body's ability to fight infection?

White blood cells, including lymphocytes, contain vitamin C concentrations up to 80 times higher than blood plasma, a phenomenon that underscores the nutrient's vital role in immune cell health. Instead of reducing lymphocytes, vitamin C is crucial for their proper function, differentiation, and proliferation.

According to the Cleveland Clinic, nutritional deficiencies are the most common cause of a low lymphocyte count, known as lymphocytopenia, worldwide. Understanding which foods decrease lymphocytes is crucial for maintaining a robust immune system.

A 2016 study on nursing home elderly with zinc deficiency showed supplementation increased peripheral T cell counts, suggesting a crucial role for the mineral in immune function. However, the effect of zinc on T cells is more complex than a simple increase and depends heavily on an individual's existing zinc status.

A 2019 study published in the *American Journal of Clinical Nutrition* found that vegetarians often have lower total white blood cell counts than omnivores, though still within normal reference ranges. To support a robust immune system and know how to increase lymphocytes for vegetarians, a strategic focus on nutrient-dense plant-based foods and a healthy lifestyle is key.

Recent research from a study on type 2 diabetes patients found that vitamin D deficiency was associated with the lowest lymphocyte counts. While not a direct "increase," this and other studies show that adequate vitamin D levels are crucial for lymphocyte function and overall immune system regulation. This article will explore the nuanced effects of vitamin D on these essential white blood cells.

According to the National Institutes of Health, proper nutrition is a crucial factor in supporting immune function and the body's production of white blood cells, including lymphocytes. While the acronym TLC is also associated with the heart-healthy Therapeutic Lifestyle Changes diet, in the context of immune health, it refers to the Total Lymphocyte Count. This article focuses on the specific foods and nutrients that can support and increase this count naturally.

According to the World Health Organization, deficiencies in certain micronutrients can impair immune function and increase susceptibility to infections. A balanced diet rich in specific vitamins is crucial for optimizing the production and activity of lymphocytes, the white blood cells that are vital for a strong immune system.
