Broccoli and raw radish diet and the gut microbiome
Does a diet including broccoli and raw radish affect gut microbiome composition in healthy adults?
Human · randomized crossover diet trial
Key findings
Differences in community composition
Beta diversity, a measure of differences in microbial communities, varied by diet (p=0.03).
Relative abundance of certain taxa
Relative abundance of Firmicutes was lower and Bacteroidetes and Bacteroides higher than on the comparison diet. The differences were more pronounced in participants with lower body mass index.
A diet containing both foods
Participants ate broccoli with raw radish under a controlled whole-diet intervention.
