What this trial studies

This study investigates the effects of a food-first synbiotic approach, combining prebiotics and probiotics, on gut microbiota and cardiometabolic health in post-menopausal women. Participants will consume yogurt with added spices or without for four weeks, followed by a washout period, and then switch to the alternative treatment. The study aims to measure changes in gut microbiota and their relationship with systemic metabolic effects, particularly focusing on short chain fatty acids and gut-derived metabolites.

Who should consider this trial

Good fit: Ideal candidates are post-menopausal women aged 50-69 with a BMI between 18.5 and 34.9.

Not a fit: Patients with cardiovascular disease, diabetes, liver disease, cancer, or significant gastrointestinal issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel dietary approach to improve gut health and reduce risks associated with cardiometabolic syndrome.

How similar studies have performed: While the use of spices for health benefits is gaining attention, this specific synbiotic approach is relatively novel and has not been extensively tested in similar studies.
