Diet and immune response: how today’s plate shapes tomorrow’s health

Abstract

Nutrition is emerging as a promising therapeutic tool to modulate the immune system in health and disease. We propose that the timing of dietary interventions is probably what determines their success. In this context, we explore recent research that identifies the early phases of dietary intervention as critical time windows for modulating immunity and optimizing cancer therapy. Furthermore, we highlight how the timing of intervention can yield different outcomes. The data suggest that nutrient availability and absorption over a short period can significantly impact mammalian immune and even non-immune landscapes. This, in turn, can lead to changes in mucosal and systemic immunity, potentially exacerbating or ameliorating inflammation, and perhaps influencing tumor cells and their response to cancer therapies.
