Summary
This trial will study whether blueberries can help prevent obesity-linked metabolic syndrome by looking at the microbes in the gut and the metabolites produced.
Who is the study for?
This trial is for Caucasian men and premenopausal women in good health, with a BMI of 25-40 or waist circumference over 80 cm for women and 94 cm for men. Participants must have high triglycerides or fasting insulin levels. Exclusions include heavy drinkers, recent surgery or antibiotic use, smokers, certain medication users, metabolic disorder sufferers, blueberry allergies/intolerances, significant weight change recently, or special diets.
What is being tested?
The study tests if daily consumption of either real blueberry powder or a placebo affects the gut microbiota and can help prevent obesity-related metabolic syndrome. It combines genetic material analysis (metagenomics), gene expression profiling (transcriptomics), and small molecule characterization (metabolomics) to understand how blueberries might benefit heart and metabolic health.
What are the potential side effects?
Since this trial involves consuming blueberry powder which is generally considered safe as part of a regular diet; no significant side effects are expected beyond potential allergic reactions in those sensitive to blueberries.
