A client presents with frequent loose stools after taking antibiotics. Which probiotic has the most evidence for antibiotic-associated diarrhea?
Answer: Saccharomyces boulardii

Which dietary pattern has the strongest research support for promoting microbiome diversity?
Answer: Mediterranean diet
The Mediterranean diet, rich in diverse plant foods, fiber, and fermented foods, consistently shows the strongest association with increased gut microbiome diversity.
Zonulin is a protein biomarker that, when elevated, indicates increased:
Answer: Intestinal permeability
Zonulin regulates tight junction permeability, and elevated serum zonulin levels are a biomarker for increased intestinal permeability (leaky gut).
Which component of kombucha is responsible for its probiotic benefits?
Answer: The SCOBY (symbiotic culture of bacteria and yeast)
