The Power of Bifidobacteria and Gut Health with Dr. Christine Bishara

In this episode of the Vibrant Wellness Podcast, Dr. Emmie Brown and Melissa Gentile are joined by Dr. Christine Bishara, an internal medicine physician and author of The Gut Revolution, whose clinical work focuses on the intersection of nutrition, microbiome science, and immune function. Dr. Bishara presents evidence supporting the use of time-restricted eating, dietary diversity, and microbial restoration to improve metabolic health, cognitive performance, and immune resilience.

Dr. Bishara shares clinical data and personal experience supporting “intermittent eating,” a reframe of time-restricted feeding emphasizing nutrient-dense intake within a limited window. The discussion highlights the therapeutic importance of microbial metabolites, mainly in decreasing dependence on external supplements.

The episode also explores the role of Bifidobacteria in both children and adults, how it declines with age and modern diets, and how targeted diet and timing strategies can boost Bifidobacteria levels, enhance immune regulation, and improve viral resistance.
