Sponsor: Laval University
Conditions: Gut Microbiota, Metabolic Syndrome
Interventions: Raspberry supplement
Countries: Canada
There is growing evidence that nutritional intervention with dietary polyphenols can positively modulate the gut microbiota to improve cardiometabolic health. Whether the beneficial effects of raspberry on obesity and the metabolic syndrome can be linked to their potential impact on the gut microbiota and intestinal integrity remains speculative at this time. Moreover, the mechanisms of action underlying health benefits associated to raspberry consumption are still unknown. The investigators are thus proposing to combine the study of metagenomics, transcriptomics and metabolomics to test whether a prebiotic activity of raspberry can play a role in the prevention of obesity-linked metabolic syndrome in a clinical setting.
