Comparing Vegan and Keto Diets: Rapid Impact on Immune System

A study by the National Institutes of Health found that switching to a vegan or keto diet for two weeks led to distinct immune system responses in participants. The vegan diet primarily affected innate immunity and red blood cell pathways, while the keto diet influenced adaptive immunity and a wider range of proteins. Both diets significantly altered participants' microbiomes and metabolic processes, demonstrating the rapid and diverse immune responses to dietary changes. This research suggests potential for tailored diets to prevent or complement disease treatments.
