Conclusion
The findings from this study show that motivation and opportunity are the main drivers of regular soya consumption while knowledge was the most reported barrier to consumption among healthy, Asian post-menopausal women. Using a theory-based approach, we demonstrate that perception is fluid and influenced by knowledge gained over time. We propose that understanding perception within specific cultural and population context could be the solution to improving compliance and retention in dietary intervention trials. Future clinical trials investigating the soya and public health relationship are warranted to enable better communication and informed decision-making between patients and their healthcare professionals.
