What this trial studies

This study investigates how supplementation with milk and yogurt affects bone health and body composition in Canadian young adults aged 19 to 30 years. Participants with low dietary calcium intake will be assigned to consume either milk or yogurt alongside their habitual diet over a 24-month period. The research aims to fill the knowledge gap regarding the long-term impact of these dairy products on obesity and osteoporosis, which are significant public health concerns in Canada. By examining the role of probiotics and key nutrients in dairy, the study seeks to provide insights into improving health outcomes in this age group.

Who should consider this trial

Good fit: Ideal candidates are Canadian young adults aged 19 to 30 with a dietary calcium intake below 1000 mg per day.

Not a fit: Patients with a body mass index over 30 kg/m2 or those with certain medical conditions affecting bone health will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved bone health and body composition in young adults, potentially reducing the risk of osteoporosis and obesity.

How similar studies have performed: Previous studies have suggested positive effects of dairy consumption on bone health and body composition, indicating potential for success in this approach.
