What is the term for the increase in white blood cells after eating?

The term "Digestive Leukocytosis" specifically refers to the observed increase in white blood cell count following a meal. This phenomenon occurs as the body activates its immune system in response to the ingestion of food, particularly high-protein or high-fat meals. This increase in white blood cells is thought to be a part of the body's natural response to potential pathogens or allergens that may be present in the food, as well as to manage the increased metabolic load caused by digestion.

Postprandial Response indicates a general physiological change after eating, but it does not specifically denote the increase in white blood cells. Nutritional Reaction is a broad term and does not specifically describe the white blood cell increase. Metabolic Surge suggests an increase in metabolic activities but does not directly relate to changes in white blood cell count. Therefore, Digestive Leukocytosis is the most precise terminology for this biological process following food consumption.
